What is a Rotary Lawn Mower?

A rotary lawn mower is a conventional cutting device that has horizontal blades mounted beneath the unit in order to trim grass. The unit operates by a gasoline or electrically-powered engine, which propels the sharpened blades in a circular motion around a centralized pivot shaft. As long as the cutting unit remains within perfect balance, a rotary lawn mower can trim large amounts of grass faster than many other comparably-designed mowers, and the result is often a much more uniform pattern as well. An overwhelming majority of the world’s current lawnmowers implement the rotary design due to its simplicity, performance, and relatively low maintenance costs.

The key to making a rotary lawn mower operable is the actual cutting blade itself, which is normally made from a solid cast of steel. Different manufacturers will implement various lengths and features of the rotary blade to increase the cutting and mulching capacity of the lawnmower while it is in use. Since the heavy deck forces grass to lean forward as the rotary lawn mower passes over it, the blades are designed with an angular pattern across the sharpened side to generate a lifting air pattern. This forces the grass to stand back upright so a smooth, uniform cut will be made across the entire cutting surface.

The technology behind the rotary lawn mower is thought to be an improvement on reel designs due to several factors. Since reel lawnmowers rely on a vertically-powered circular motion where several inline blades strike the grass in tandem, there is a large amount of upkeep to ensure that the device cuts properly. Damage to even a single blade could lead to sporadic patches of uncut grass, but in a rotary-style lawnmower, this is far less of an issue since the blade is propelled at high revolutions by an engine.

There are also several variations of a rotary lawn mower available to the general public. Self-propelled rotary lawn mowers add a drive belt to the wheels in order to eliminate the need for the device to be manually pushed, and riding lawnmowers also implement this technology by utilizing a larger, more powerful motor to carry the operator while the device is in motion. Some rotary lawn mowers also utilize two separate blades that are mounted side by side to grant a larger cutting radius, and industrial mowers may have up to eight vertically-aligned blades to mow large fields or crops. A mulching rotary lawn mower creates a more powerful updraft so that the individual blades of grass will remain within the cutting chamber longer, allowing for finer cuts that will be more easily absorbed by the soil.

The following description applies to most small rotary lawn mowers with direct driven blades. The vast majority of these use either Tecumseh (as found a variety of Sears/Craftsman equipment) or Briggs Stratton engines. However, similar Комментарии и мнения владельцев apply to others as well including Lawnboy two stroke engines and the more modern Honda and other overhead valve type of engines.

The assumption is that the engine started and ran normally prior to the incident. Now, no matter how many times you yank the starter rope or run the electric starter, it will not start at all, bucks, kicks back, backfires, or fails to develop enough power to keep going on its own.

If the blade struck a solid boulder while the engine was set on ‘high’, more severe damage is possible as even with soft metal keys locking the blade and flywheel to the crankshaft, the inertia of the rotating blade is acting sideways against the crankshaft in addition to suddenly stopping its rotation. This can result in a bent crankshaft. The end of the crankshaft with the blade adapter could be bent without affecting the bearings or internal parts. This would need to be tested for as well. Not that such an occurrence is that much better. the crankshaft would still have to be replaced but at least the bearings in the crankcase will not be damaged.

If the starter will not turn the crankshaft (assuming you remembered in your haste to engage the safety bar). it is seized or will only rotate part of a revolution before hitting against something solid inside. then you probably have serious internal damage that will require a complete strip down and replacement of some (expensive) parts. If it turns but much more tightly than you recall (assuming you do have the safety bar engaged!) then the crankshaft may be bent. again very expensive. Repair may not be worth it.

However, in most cases, what has happened is that either or both of the blade lock key and/or flywheel key have sheared to protect the crankshaft from serious (and terminal) damage.

If the blade lock key broke, the blade will no longer turn rigidly with the crankshaft and provide the inertia required by many small engines with undersized flywheels. In this case, the engine may try to start but die out with a few “putt-putts” or even kick back on the starter cord. (As a side note, attempting to use a lawn mower engine as a replacement on a piece of equipment that doesn’t have something to substitute for the blade’s inertia may not work for this reason.)

If the flywheel key broke, the ignition timing will likely be totally wrong and the result may be no ignition, backfiring, kickback, or weak or total loss of power.

First, pull off the spark plug wire and tie it securely away from the spark plug terminal (several inches minimum) or remove the spark plug entirely so that there is no chance of the engine accidentally starting. Even though it will not start now no matter what you do, the underlying problem could actually be a flooded carburetor or something else which may correct itself while you are working. Never take chances.

Drain the gas or remove the fuel tank. This will prevent gasoline from spilling out the gas cap vent hole or flooding the engine through the carburetor since you will need to tip the mower to get underneath.

CAUTION: Immediately check for oil leaks at the oil filler pipe or elsewhere.

The mower can usually be set on its side for a few minutes without harm but if these occur. you will have to work with it tipped less than 45 degrees or so. propped on wood blocks. Or, use this as a good excuse to perform an oil change and drain the oil (even if the engine is cold, most of the oil will drain out. it will just take a little longer). Just don’t forget to refill the crankcase with fresh oil once you have completed your work!

Using an old rag and/or proper work gloves, grasp the blade and attempt to rotate the blade and crankshaft.

CAUTION, despite your lack of maintenance, the blade may be sharp!).

The blade and crankshaft should rotate together. If there is slippage, the key has broken and will require replacement of just the key or the entire blade adapter plate depending on design. If it appears to be intact, then you can assume the flywheel key has broken. The blade key may be broken as well but it is not likely the reason for your failure to start. You should remove the blade to determine this for sure before restoring the mower to service in any case. See the section: Non-violent blade removal.

You can possibly avoid removing the flywheel for inspection of the key by unscrewing the sparkplug, rotating the crankshaft so the piston is at TDC, and noting the location of the magnet on the flywheel relative to the magneto coil pole pieces. The magnet should be pretty close to the magneto in that position. If this is not the case or just to be sure, the flywheel will have to come off to inspect and possibly replace the key.

To get at the flywheel key itself, some disassembly is required.

The Rotary Power Mower And Its Inventor: Leonard B. Goodall

Earliest known version of the Goodall mower, currently in the collection of Jerry Nance of Odessa, Missouri.

The Goodall family home at 444 E. Market, Warrensburg. The earliest work on the Goodall mower was done in the basement of this home, which is now the property of the local school district and is used for offices.

This first blade was presented to Goodall when he retired in 1952. The inscription reads, ‘Blade used on first vertical drive rotary mower made by Leonard Goodall, 1931.’

Consumers Union celebrated its fiftieth anniversary in 1986 bypublishing a special commemorative book, I’ll Buy That, inwhich it identified fifty twentieth-century inventions that had‘revolutionized the lives of consumers.’ 1 One ofthe fifty, the rotary power lawn mower, originated in the basementof a house on East Market Street in Warrensburg, Missouri, whereLeonard B. Goodall lived and developed the mower. His workrepresents the story of an individual who saw a need and, with thespirit of an entrepreneur, set out to meet it.

Immediately after World War II, an important part of theAmerican Dream included owning a home with a yard and, perhaps,even a white picket fence. Just as air-conditioning allowed peopleto live comfortably in warm climates. Goodall’s mower enabledindividuals to maintain relatively large lawns in a neat andattractive fashion.

Prior to the invention of the rotary mower, mowers were of thereel type. They could not cut high grass, which made it difficultfor individuals to push them long enough to mow a large yard. Aslong as most people lived in cities or on farms, this presented noproblem. City dwellers had either no yards or only small ones, andfarm animals served as ‘mowers’ for rural inhabitants. Thepost-World War II suburbanization movement created a great need fora mower that could be used on large lawns, and Goodall’s rotarypower mower responded to that need.

Born to farmers in Delphos, Kansas, on November 17, 1895,Leonard B. Goodall grew up in the rural and small-town atmosphereof central Kansas. Although he completed only eight grades, he hada curious mind about mechanical mattersa curiosity that remainedwith him throughout his life and dominated his professionalactivities and work habits.

As a teenager, Goodall attempted to repair a tractor with opendrive while the engine ran. The vibration caused the tractor tojump into gear. His left leg caught in the gears, necessitating itsamputation. This tragedy later had a dramatic impact on his life.The handicap and his resulting inability to push a reel-type mowercaused him to seek another approach to lawn mowing.

As a young man, Goodall moved to Salina, Kansas, where hemarried, and he fathered a daughter, Viva. The marriage ended indivorce, and in the mid 1920s he moved to Kansas City, Missouri.His curiosity had led him to develop a strong interest in twotechnological advances still in their infancy in the 1920sthe radioand the automobile. He had read and studied all that he could findabout them.

While looking for a job, Goodall responded to an advertisementin the Kansas City Star for a radio repairman at the College Store,a privately owned book and school materials store in Warrensburg,Missouri. The exact date of this move is unknown, but his familybelieves it occurred about 1927. Although he knew little aboutrepairing radios, neither did anyone else, and the College Storehired him. He moved to Warrensburg, found a single room in arooming house on West Culton and began work. The owner of thestore, Kenneth Robinson, became a lifelong friend, andRobinson’s son-in-law, Garrett Crouch, later served asGoodall’s attorney and as attorney for the GoodallManufacturing Company.

Soon after moving to Warrensburg, two important events occurredin Good-all’s life. First, he met Eula Johnson, a waitress inthe Estes Hotel coffee shop where he ate regularly. She would laterbecome his wife. Second, he became friends with Stanford McCann, anemployee at the Ford dealership. McCann helped Goodall get a jobthere, and he soon left the College Store to work for TheodoreShock, owner of the Ford dealership. Goodall served first as amechanic and later as shop foreman, a position he held through theyears of the depression and into the late 1930s.
