WH48A Commercial Walk-Behind Mower

An exclusive, two-year, single-source, bumper-to-bumper warranty is for all John Deere commercial mowing equipment. The warranty is best in class and places John Deere at the forefront of commercial mowing. It is hassle free, with one company handling all of the paperwork.

 

Rubber, wide-profile, flat-free front caster wheels provide a smooth cut.

John Deere provides application-specific Environmental Protection Agency (EPA) and California Air Resources Board (CARB) approved field-installed propane conversion kits for specific John Deere Commercial Walk-Behind Mowers, QuikTrak Mowers, and ZTrak Mowers. The conversion kits include all components required to convert the engines to operate on propane fuel. Single-tank or dual-tank brackets (depending on the vehicle) are provided for securely holding the propane tank(s) to the vehicle.

Propane tanks are not included.

Optional altitude kit is required when operating at altitudes above 2000 ft (610 m). The operator’s manual provided with the propane conversion kit provides further details. Parts must be ordered separately through John Deere Parts.

Propane facts:

• Propane is flammable and commonly used as a fuel.
• The molecular formula of propane is C3H8, and it is in the family of liquefied petroleum gases (LP gases). The other LP gases include butane, propylene, butadiene, butylene, isobutylene, and mixtures thereof.
• Propane is commonly available and has proven to be a dependable, safe, economical, and clean-burning fuel. It can be used as household fuel, industrial fuel, and fuel for internal combustion engines. Propane has been used as a fuel since 1910.
• At atmospheric pressure, propane boils at -44°F (-42.2°C), meaning it typically exists as a vapor. However, when contained under pressure, such as in a propane cylinder, it can exist as a liquid.
• Propane is naturally odorless, but includes an additive odorant, usually mercaptan, which gives it a distinct odor.
• Vapor propane is heavier than air, meaning it will settle in low areas such as along the ground or in drains.

 Advantages of John Deere propane conversion kits include:

• Reduced fuel costs, up to 30 percent depending on fuel prices
• Lower emissions
• Reduced fuel-system maintenance
• Maintains John Deere warranty
• EPA and CARB certified
• May qualify for national and state rebate and incentive programs. Please visit www.propane.com/commercial-landscape/programs-and-incentives/ for further information.

Worthington tanks are manufactured by Worthington Industries, Inc.

The WH Series Mowers are equipped with an infinitely variable hydrostatic drive system with reverse, which does the following:

• Provides infinite ground-speed adjustments - 0 mph to 7 mph (0 km/h to 11.3 km/h) to meet the mowing application
• Enables a smoother transition from one speed to another 
• Gives a reverse speed of 3 mph (4.8 km/h), enabling the operator to back out of tight mowing areas and increase productivity

The WH Series Mowers also come equipped with a six-position hydrostatic-transmission adjustment plate. This feature allows an operator to adjust the sensitivity of the hydrostatic transmission to provide ultimate control and comfort.

John Deere commercial mower decks have always demonstrated quality, performance, and durability. The 7-gauge, 0.179-in. (4.6-mm), fabricated floating mower deck delivers an extremely high-quality cut in diverse conditions.

Features:

• High blade-tip speed of 18,000 fpm (5,486 m/min) for more blade strikes per inch mowed 
• Floating suspension to enable the best-possible cut
• Wide, raised discharge chute for more even clipping distribution
• Reinforced front lower edge for strength and durability
• Easy height-of-cut changes without tools
• Four, dual-captured, adjustable-height anti-scalp wheels 
  

• Tube design with hanger brackets that provide a free-floating deck for a smooth cut with a reduced chance of scalping or scuffing by following the contour of the ground 
• Easy-attach belt shields to allow quick access for service 
• Wide, rolled lips for additional structural strength 
• Greaseable spindles with easy top access for simplified servicing 
• Two-coat paint covering to protect and resist corrosion 
• Hardened steel blades that extend cutting time and increase durability 
• Large discharge to evenly disperse expelled clippings
  

 

Wide and large drive wheels provide excellent traction with low turf compaction. They also provide maximum curb climbing. The square shoulder improves hillside performance.

 

The tire sizes for the WH Series models are as follows:

• WH36A - 16x6.50-8 in. 4 PR
• WH48A and WH52A - 16x7.50-8 in. 4 PR
• WH61A - 16x8.50-8 in. 4 PR
  

All of the controls on a WH Series Mower are within comfortable reach of the operator.

 

The location and simplified operation of the following controls on all models offer greater convenience, improved productivity, and increased safety: 

• Operator presence system – The bail must be depressed to operate the unit; the machine must be in neutral and the power take-off (PTO) must be disengaged to start.
• Separate choke and throttle – This takes the guesswork out of choke operation, and there is less fouling of plugs.
• Loop-type controls – These controls provide ease of operation. 
• Front adjustable cruise bar – This bar allows setting the maximum mowing speed to match conditions.
• Reverse index bar – This bar makes the machine easy to control in reverse. 
• Adjustable height of controls for short and tall operators – There are three height settings with 3 in. (7.6 cm) of total adjustment. 
• Color-coded and clearly marked switches and buttons – These enable simplified operation.
• Bilingual decals – Decals are provided in English and Spanish.
