W61R Commercial Walk-Behind Mower has an electronic fuel injected (EFI) air-cooled, vertical-shaft engine.

• 25 hp (18.6 kW)
  • 45.6 cu in. (747 cc)
  • Electric start with a large 300 cold-cranking amp (CCA) battery for fast, convenient starts
• EFI allows for fast starts without use of a choke - no choke lever is needed.
  • Starts are quick and easy, even for inexperienced operators.
  • EFI increases uptime.
  • Fast, reliable starts are routine just like with a modern automobile. EFI automatically meters fuel, including the extra fuel needed to start a cold engine, eliminating flooding from unnecessarily choking a warm engine. No carburetor adjustments are needed at altitude.
  • There are no choke-related problems since the choke is eliminated, thus ensuring operator confidence and quick starts, even in cold ambient temperatures (snow blower use). The mechanical throttle cable is replaced by an electric linkage that is not susceptible to wear or freezing.
  • Cost of ownership is reduced.
  • EFI precisely meters fuel to each engine cylinder. Fuel usage can be expected to be about 10 percent less than with a similar carbureted tractor.
  • Maintenance expenses are reduced because of fewer complaints related to hard starting, vapor lock, misfire, run-on, or fouled spark plugs.
• V-twin design for smooth operation and fast starts
  • Consistently strong torque at low- or high-speed operation

• Actuates arm that creates a mechanical locking interference on both drive tires
• Brake pawl located near top of tire to eliminate contact with curbs

An optional mulching attachment and special mulching blades are available:

• The high-performance mulching attachment includes formed steel baffles to control the material for superior performance.
• Special mulching blades can also be used when side discharging, though overall cutting performance may be slightly less than with the standard blades.
• The mulching attachment allows for conversion of the mower deck so it can be used to perform the mulching function (grass or leaves).

OPERATING TIPS WHEN MULCHING:

• Mow when grass is dry.
• Observe the one-third rule.
  • No more than one-third of the grass blade should be cut off at one time. This allows more efficient mulching and will promote the continued good health of the grass.
  • If the desired cut height cannot be achieved by cutting off one-third, or there is clumping of the clippings, it may be required to cut higher, wait a day, then lower the mower and make a second pass.
• Mow at proper intervals, approximately every four to five days.
• Always mow with sharp blades.
• Adjust ground speed to allow the mower deck to process the clippings effectively.

John Deere commercial mower decks have always demonstrated quality, performance, and durability. Each commercial walk-behind mower is equipped with a high-quality fabricated mower deck:

• 10-gauge, 0.135-in. (3.42-mm) fabricated steel deck top with added 10-gauge, 0.135-in. (3.42-mm) spindle mounting plate
• 7-gauge, 0.19-in. (4.8-mm) side skirts with reinforcement bar

The fabricated, floating mower deck delivers an extremely high-quality cut in diverse conditions:

• Floating suspension enables the best possible cut.
• Reinforced front lower edge provides strength and durability.
• Four mower front wheels are double-captured for durability and adjustable to three positions to suit the cut height.
• Two-coat paint covering protects the mower deck and resists corrosion.
• Deep-deck design for superior capacity.
• Side and center anti-scalp wheels promote a smooth mowing job.

• Hardened steel blades extend cutting time and increase durability.
• High blade-tip speed of approximately 18,000 fpm (5,486 m/min) for more blade strikes per inch mowed.
• R Series mower decks include a rear wheel for additional anti-scalp protection.
  • Adjustable to three height positions to suit the cut height

A high-quality polyethylene deflector gives an excellent finished appearance:

• Wide, formed discharge deflector provides even clipping distribution.
• Large discharge deflector evenly disperses expelled clippings.

Caster wheels with flat-free tires contribute to a smooth, even cutting job:

• Large, flat-free caster wheels carry the mower deck smoothly over the lawn.
• Caster wheels are close to the mower deck to reduce vehicle footprint and turning radius.
  • With the wheels less exposed, there is less chance they will get snagged by immovable obstacles, thus improving maneuverability and reducing chance of damage.

MOWER CUT-HEIGHT ADJUSTMENT

A floating mower deck has several advantages over a fixed mower deck design:

• Follows ground contour more effectively for a more even cut
• Travels smoothly above the ground with minimal chance of scalping
• Easier to adjust the cutting height

Mower cutting height can be set from 1.5 in. (3.8 cm) to 4.5 in. (11.4 cm) in 0.5-in. (1.3-cm) increments:

• The free-floating deck gives a smoother, more level cut.
• Height-of-cut changes can be made without tools.
• Large handles are provided to facilitate lifting the mower deck for setting the cut height.
• Cut-height adjustment pins have 90-degree bend for easy removal and reinstallation.

Mower deck shields are easily removed with hand knobs for access to the drive belt and other service points:

• Easy-attach belt shields allow for quick access for service.
• Four hand knobs allow removal of both mower shields.
• Greaseable spindles with easy, top access for simplified servicing.
• Spindle grease fittings can be greased with shields in place.

OPTIONAL MULCHING ATTACHMENT

An optional mulching attachment and special mulching blades are available:

• The high-performance mulching attachment includes formed steel baffles to control the material for superior performance.
• Special mulching blades can also be used for side discharging, though overall cutting performance may be slightly less than with the standard blades.
