Gas lawn mower for rough terrain
Reading time: 11 minutes May 17, 2019 Vasily Andropov Gardening specialist with experience of 8 years
Conventional mowers will not cope with dense overgrown grass, uneven surfaces, narrow sections. Complex reliefs are only possible for off-road vehicles. Here you need devices with high power and durable blades. over, the width and height of mowing, as well as the type of drive, are important.
How to choose the right model for an uneven area
The main thing in the device is its design. It determines the capabilities of technology. Models of gasoline lawn mowers for uneven areas by design features. trimmers, lawn mowers, manual, self-propelled, wheeled, wheelless and riders.
It looks like a trimmer and a lawn mower
They are a bar with a cutting mechanism below. A gasoline engine, controls and shoulder strap are located at the top of the unit. They are used in hard-to-reach places (between bushes and trees, under the fence). where the trolley with wheels will not pass.
Trimmers are also used on small uneven areas. Lawns do not mow them. the height of the grass will turn out uneven. You can buy portable models both separately and in addition to a wheeled lawn mower.
Manual (mechanical, non-self-propelled)
Such a lawn mower must be pushed around the site itself. It is suitable for small areas (up to 8-10 acres). The price for manual models is budget.
The motor rotates both blades and wheels at the same time. A man only guides this cart with a pen. Self-propelled model more efficiently cope with spacious possessions (more than 10 acres).
Self-propelled or manual carts are designed for sections of 10-25 acres with a slope of not more than 30 °. Do not handle bottlenecks with wheel mowers. only a lawn mowing machine or trimmer can handle it.
Scheme of lawn mowers and gasoline engine
Reduced versions of the tractor are cabs with steering and a driver’s seat. Equipped with mounted mowers.
By type of wheel drive
This parameter affects the maneuverability of the self-propelled lawn mower and its stability in an uneven area:
- Models without a drive. Lightweight devices weighing up to 15 kg with economical fuel consumption. The downside is that they are low-power and are controlled only by hand.
- Front wheel drive. Maneuverable self-propelled vehicles, easily deployed in place with the engine running. Rough sections are impassable for them. If such a mower is still equipped with a grass catcher, then when filling it deflects the center of gravity back. displacement. higher lagging of the front wheels from the ground.
- Rear wheel drive. Stable self-propelled models for uneven surfaces (slopes, pits, mounds). In terms of maneuverability, they are inferior to front-wheel mowers.
- All-wheel drive Equally good on a flat and complex terrain. Cons of all-wheel drive lawn mowers. it is high cost, heavy weight (about 40-50 kg).
The drive in self-propelled gasoline models is of two types:
- Belt. These are inexpensive self-propelled lawn mowers, easy to operate and maintain.
- Straight. It makes less noise, saves fuel more economically. Such self-propelled lawn mowers will cost more.
According to grass mowing parameters
The performance of the mower is determined by the working width. value. faster haircuts and fuel economy. The disadvantage of wide technology is that it is difficult to go through narrow sections (between flower beds, for example). The mowing value is selected for the area of the site:
- 30–40 cm. up to 500 m2;
- 40-50 cm. 500-1000 m2;
- 50-60 cm. 1000-2000 m2;
- 60–120 cm. from 2000 m2.
According to the device of the cutting part, self-propelled and manual models are divided into three types:
- Rotary lawn mower (rotary). Equipped with 2–4 blades (blades) fixed below the vertical shaft parallel to the ground. The mowing height is adjustable by the operator, so such a device can even cope with a bumpy area.
- Drum lawn mower (cylindrical). The blades are arranged spirally along a horizontal shaft. Shears grass evenly according to the scissors principle. knives. better mowing (their number in different models varies from 5 to 10). Drum lawn mowers are only suitable for a flat lawn, because they are thin and have mediocre cross-country ability. This technique can only cope with young shoots.
- Disc lawn mower. It works more efficiently than drum and rotor models. The cutting part of the mower is made in the form of a disk. The technique belongs to the professional segment, therefore it costs more.
A gasoline lawn mower should mow grass at least 1/3 of its initial height. Otherwise, the site will turn yellow, lose its decorative effect. Grass with a height of 10-15 cm is cut to 5-8 cm. There are three types of mowing adjustment in mowers:
- Screw. The wheel shaft must be manually moved up or down. A primitive inconvenient way, typical for cheap mowers.
- Individual. Each wheel is equipped with a separate lever for manual adjustment.
- Central. The mower is regulated by a single lever. This is especially convenient when the height needs to be changed several times in one haircut.
According to the material of the manufacture of the unit body
The choice comes down to three options:
- Plastic. Lightweight, inexpensive material with low strength and short life.
- Galvanized steel. Durable material, resistant to moisture and direct sunlight. It is more expensive than plastic, and scratches on its protective coating are fraught with corrosion.
- Aluminum. Lightweight, durable material, resistant to mechanical stress and UV radiation. Corrosion, unlike steel, is not exposed. The downside is that aluminum lawn mowers will cost 3-4 times more expensive.
By diameter and number of wheels
The chassis determines the patency of a gas mower. Models with three wheels are more maneuverable, and with four. more stable. It is desirable that the front wheels are swivel in either of both cases. So it is more convenient to cut a site with bumps or thick grass.
It is important that the wheels in the mower are on bearings and not on the bushings. Then they rotate more easily and last longer. Sizes are selected according to two rules:
- Larger diameter. it is easier to move around an uneven area, mow tall grass.
- Already the wheels are deeper than the tracks from them.
Engines in lawn mowers are selected by area:
- Household motors (low power). 3.5-5 horsepower. Suitable for plots up to 5 acres, since the mowing width of domestic lawn mowers does not exceed 40 cm. It is important to remember that low-power engines cope only with young shoots. Their working life is 500 hours, after which repairs may be required.
- Semi-professional (medium power). 5–7 hp Designed for plots up to 18 acres. Lawn mowers with such motors will cut off thick, hard and thick shoots. They cost more than household models, weight and dimensions are also greater. Working life. 700 hours.
- Professional (high-power). more than 7 hp They are used on an industrial scale (parks, squares, fields). They are reliable and productive, but expensive, heavy, costly to maintain. The working life of such engines exceeds 1 thousand hours.
The mower motor class also affects the mowing width:
- household engine. 30-40 cm;
- average power. 40-60 cm;
- professional. 60-120 cm.
By the frequency of the working cycle, gasoline engines are divided into two types:
- Push-pull. They work on a mixture of gasoline with oil. They are cheap, quickly gaining momentum, easy to maintain. In addition, these engines are lighter than four-stroke ones (the difference in weight reaches 2-3 kg). Only they are noisier, and the working resource is half as much.
- Four stroke. Act on clean fuel without adding oil. powerful than two-stroke, moreover, fuel is used more economically. Emissions are less, noise is lower, gasoline burns without a trace. The cost of such motors is more expensive, it is more difficult to service them.
By additional functions
A grass catcher for a gas mower is an optional item, but greatly facilitates the work. It occurs in three forms:
- Soft. It is made of synthetic fabric (mesh). Light, slowly filling, but it is difficult to clean. the remains of mowed grass stick inside the bag.
- Plastic. Easy to clean (just rinse with water), but quickly fills.
- Combined. The walls are fabric, and the top and bottom are made of plastic. Such a container fills slowly, it is easier to clean than soft bags.
extras. wider mower functionality:
- Side discharge. Mowed grass flies off to the side, and not under the operator’s legs.
- Mulching. Grass is crushed and scattered around the site as fertilizer. The function is suitable only for dry and soft vegetation. Otherwise, the mulch will crumple, cover the lawn unevenly, clog the roots of the grass. So the lawn will become untidy and will have to be combed.
- Self-starter. Instant start of the gasoline engine.
- Transmission. Provides up to four speed modes on wheel mowers (in riders up to 12), which makes it easier to control on uneven areas.
- Rubberized handles. Simplify the transportation of the device, reduce vibration from the motor.

What is a manual gas mower?
Video: How Much Oil To Pour Into A Husqvarna 356 Lawnmower
Manual gas mower or lawn mower? We will understand in terms
Both the lawn mower and the lawn mower are effective tools for mowing grass. But this is not the same thing.
A gasoline trimmer (lawn mowing machine) is a tool that you hold in your hands (part of the weight can be transferred to the shoulders using a special suspension). It is equipped with a gasoline engine, shaft and gearbox that transmit torque to the cutting unit. As the latter, a line with a fishing line or a disk can act. lawn mowing can cut tall grass, work on uneven surfaces and slopes, as well as in hard-to-reach places (among trees and shrubs, close to fences, borders, etc.).
A gas mower is a car on wheels, also equipped with an internal combustion engine (usually a 4-stroke), and the cutting body is a metal knife that is mounted on the engine crankshaft using an adapter with shear keys (to protect the motor when the knife hits a hard object ) The main purpose of the device is mowing grass on flat surfaces (with a permissible slight bias).
As you can see, the difference between the trimmer and the lawnmower is very significant, so the term "manual gasoline lawnmower" is not quite correct, although it is quite common, both to refer to trimmers and non-self-propelled gasoline lawnmowers.
If you are considering buying a gas trimmer, then we hope that the information presented below will be useful. We will figure out what criteria should be taken into account when selecting, as well as what factors the price of a manual gas mower (more specifically, lawn mowers) depends on.
Defining selection criteria
Choice is sometimes quite a difficult matter. In order to choose the model that is best suited for you, you need to determine criteria that are important and not very, by answering such questions:
- How will we use the lawn mowing (in a professional mode or for a private house)?
- What will we cut. grass, weeds, shrubs, small trees?
- What type of engine is preferred. push-pull or four-stroke? We will talk about the advantages of each type below.
- The shape of the handle (see also below).
- What are your price expectations?
- The choice of the manufacturer (brand).
Professional and private use
As a rule, the purpose of lawn mowing can be indicated in the characteristics (Application): private, universal, professional.
A professional tool cannot be cheap, because in its design, such technologies and materials are used that can achieve high wear resistance and the ability to withstand heavy loads. For example, high-quality steel, special hardening, forging, protective coatings of the walls of the cylinder and piston. The scope of use of such a tool: agriculture, farming, utilities, road maintenance services, landscaping and landscaping, contracting organizations, etc.
Universal lawn mowers are machines for private use, but designed for large areas or large volumes of work. They partially use the technologies and materials used for the manufacture of professional tools to increase the resource on the one hand, and not go too far at a price on the other. Such devices are perfect for large private households, landscaping kindergartens and schools, caring for territories adjacent to office, administrative and industrial buildings, etc.
Private use is a small amount of work, first of all, it is a summer house or a country house. There are no daily and many-hour loads, the resource of such a gas trimmer for grass is simply not designed for this. Accordingly, a machine for private use has a relatively low price.
Why is it important to categorize an instrument? The thing is that if for professional use you get an inexpensive mower designed for home use, you will soon have to look for a replacement for it, as it will either very quickly exhaust its life or overheat from excessive loads. And if at home you are considering a professional braid, then you risk overpaying for performance characteristics that you do not need.
What will we mow?
Having decided on the category of the tool, you can proceed to the specifics of the work.
If it is just mowing grass around trees, shrubs and other objects. a trimmer nozzle with fishing line is used, which rotates at high speed, and the sticking out "antennae" of fishing line easily cut grass leaves. The fishing line is safer for the scythe, in terms of striking hard objects (the scythe will not receive any damage).
If you are going to cut a tall and hard weed, a metal disk for grass with blades will be optimal. For more complex jobs, such as pruning shrubs and small trees, a disc with small teeth, like a saw, is suitable.
As a rule, a trimmer nozzle is included with any lawn mowers, a grass blade comes with most models, but a brush cutter is less common. In any case, it is not at all necessary that these cutting devices are included in the kit. they can be purchased separately, however, not every scythe can work, for example, with a disk for bushes, this issue will need to be clarified.
two-stroke and four-stroke lawn mowers
There are two types of cars with motors on the market. Recently, versions with 4-stroke engines are gaining more and more popularity due to their advantages:
- High reliability and resource, better cooling, less risk of overheating.
- Less noise and vibration due to design features and fewer revs. Accordingly, lower fatigue from work, higher comfort for the operator.
- Mixing gasoline with oil is not required. everything is poured separately.
- Respect for the environment: compared to two-stroke engines, they have a much lower level of harmful emissions (unburned hydrocarbons, nitric oxide).
- Profitability. A four-stroke engine consumes 2 times less fuel than a two-stroke engine.
Advantages of a 2-stroke engine:
- Smaller size and weight.
- Simple and inexpensive design.
- It produces more power per unit of working volume.
- Ability to work in any position (strongly inclined, vertical). This quality can be used for the application of various attachments for lawn mowing (for example, a nozzle trimmer or brush cutter). As for the 4-stroke engine, if you turn it over, the oil can get into other parts of the engine, and it simply stalls and stops turning on. You will have to contact the service center for disassembly and washing.
Petrol lawn mower handle shape and shaft type
The following types of lawn mowing arms and their purpose are distinguished:
Loop (or D-shaped, also Q-shaped). Ideal for moving between different objects in areas (trees, shrubs, hedges).
The lawn mowing shaft is a long shaft that is located inside the rod, with the help of which the torque is transmitted from the engine to the gearbox. This system may have the following structure:
- Direct non-separable. Perhaps the most reliable system. Professional machines are equipped with only such a variety.
- Direct collapsible. It allows you to conveniently transport and store the tool, however, the joint can become a weak point in case of careless handling.
- Curved non-separable. Very simple and inexpensive, but it is not designed for heavy loads. This variety is possessed by the most budgetary braid models for home use.
Brands and prices
High quality cannot be cheap, because it is the result of a lot of work by engineers and designers. The development of new solutions can take months and years of work, testing of prototypes to find the right balance between price and quality.
We work only with reliable brands that are responsible for their technology not only in words. Our range includes lawn mowers from brands such as Oleo-Mac, Caiman and Kaaz.
Oleo-Mac. Italian design and production. The brand offers a wide range of models for the needs of any user (both private and professional), it is constantly developing, offering all new solutions, but the high quality standard remains unchanged in the areas of performance, reliability, convenience and safety.
The Caiman and Kaaz trademarks are made in Japan, and the “Made in Japan” mark is the pride of the factory. The company did not, along with the global trend, transfer assembly line mowing lines to other countries where it would be cheaper. She believes that this is the only way to preserve our own know-how and high culture of production. At the same time, the factory offers highly competitive products not only due to quality, but also to price.

Which is better. STIHL or Husqvarna
The shield of the Husqvarna lawn mowers is larger in size, the engine is completely covered with plastic, the unit starts more smoothly, gently picks up the necessary speed. All components are optimally easily and quickly repaired.
Stihl starts up worse, it sounds sharper, the color of the plastic gets dirty. At the same time, Stihl lawn mowers use maintenance-free gearboxes that do not require additional lubrication. Huskvarnovsky must be lubricated, then only a long service life is guaranteed. The Stihl piston group withstands a not very high-quality fuel mixture, while not failing.
A big plus of STIHL trimmers are ergonomic vibration damping pads that can be used for a long time without unpleasant sensations. The fuel consumption of STIHL lawn mowers is 20% lower, and the emission of harmful substances into the atmosphere is 70% less. It is noted that the constantly switched on ignition on the Husqvarna is, in fact, a serious minus, based on safety precautions.
The price of the Stihl lawnmower is much lower than the Husqvarna counterparts. Nevertheless, the models of both brands are in great demand, which means they have a right to exist. And what choice the consumer will make will depend more on personal preferences than on specific technical characteristics.
Comparative review of the Lawnmower Stihl FS 55 VS Husqvarna 128R
Features of operation, maintenance
For each Stihl trimmer model, the factory operating instructions provide detailed information about the device, the principles and features of the unit. Strict adherence to the manufacturer’s recommendations significantly extends the life of manual mowers.
- Stihl lawn mowers consume a fuel mixture of AI-92 branded gasoline and STIHL engine oil for two-stroke engines in a ratio of 50: 1.
- There are several brands of branded oil, the best is considered STIHL HP Ultra. In the case of using non-original engine oil, the fuel mixture is prepared in a ratio of 25: 1.
- The prepared mixture should not be stored for a long time (no more than 1 month), unlike the original STIHL MotoMix fuel mixture, which preserves its properties for up to 2 years.
- STIHL grease is used to lubricate the gears; control is performed every 100 hours of operation. The air filter is usually changed annually.
- Sharpening a metal cutting tool is performed as necessary, usually a few filing movements are sufficient.
When using electric mowers, there are no problems with fuel, however, it is necessary to observe specific precautions when working with a power tool. A special cable lock prevents the STIHL trimmer from unexpectedly disconnecting from the network.
Stihl cordless lawn mowers, depending on the model’s equipment, provide different modes of operation without recharging. from 12 minutes (model FSA 45) to 420 minutes (model FSA 130). Mowers are available in different configurations: with a 36 V battery and a charger and without the specified equipment.
Charging time depends on the size of the battery and the type of charger. A special quick-charging device AL 300 charges the AP 160 battery in just 25 minutes, which ensures uninterrupted operation of the Stihl FSA 65 lawn mowers for about 1 hour.
Possible malfunctions, their elimination, repair
The great advantage of the STIHL lawn mowers is their simple design, reliability, and durability. The effective operation of the trimmer is largely dependent on the owner. The manufacturer warns of the need to comply with the rules for safe, competent operation of the units:
- Installation of special protective devices on cutting nozzles.
- The use of all cutting devices. mowing heads, metal and polymer cutting blades, strictly for its intended purpose.
- Increased risk of kickback when working with a saw blade in the black sector.
- Precautions when working with brush cutters. a safe distance from the cut trees.
- Saw blades should seem to soar above the ground at a distance of about 20 cm from the surface.
- Compliance with the operating mode: for electric and domestic gasoline models, work / rest for 20 minutes, for professional ones. work 50 minutes / rest 10 minutes.
- Before prolonged downtime or storage of STIHL lawn mowers, to avoid breakdowns, the fuel from the tank must be completely drained.
After prolonged use of the Stihl manual lawn mowers at full load, it is recommended that you leave the engine idling for several minutes. Such a measure will help to avoid stagnation of heat in the carburetor and the ignition system, reduce the load on the drive parts, since excess heat will be removed by the air stream.
The most common problems at work owners can fix on their own:
- The motor stops at idle. carry out the standard setting of the idle adjustment screw.
- The cutting tool moves at idle. turn the idle screw counterclockwise until the tool stops, then make another 1 / 2-1 revolution in the same direction.
- Often the engine stalls. check and clean the fuel channel from contamination.
- When operating Stihl brush cutters in the cold season, do not forget to put them in winter mode. installation of a kit for preheating air.
- If the engine does not work satisfactorily with the carburettor adjusted correctly and the air filter cleaned, the muffler should be sent to check for coking.
