A commercial-quality, 34.5-hp (25.7-kW) gross at 3600 rpm, air-cooled engine with EFI powers the QuikTrak™ Mower:

• Overhead valve design
  • More horsepower and torque per cubic inch of displacement
  • Better fuel efficiency
• EFI with electronic throttle control
  • Electronically adjusts the supply of both fuel and air, responding instantaneously when the mower transitions from light to heavy mowing.
  • Unlike mechanical governors that droop under load, torque rises while maintaining constant full-throttle engine speed.
  • Productivity and cut quality are improved because the mower blades keep turning at full speed, delivering optimal cut quality and dispersion of clippings.
• Immediate starting in hot or cold ambient temperatures or after long periods of seasonal storage
• No choke linkage for the user to operate
• Higher reliability with the elimination of vapor locking, misfiring, run-on, and after-bang
• Automatic altitude compensation
• Delivers fuel precisely for added efficiency
• Reduces the potential for plug fouling
• Standard dual-element, canister-type, dry replaceable, heavy-duty air cleaner with secondary safety element
• V-twin design
  • Fast starts
  • Smooth operation
• Vertical shaft for efficient transfer of power to the transmission
• Fuel pump for consistent and reliable fuel supply to the carburetor
• Full-pressure lubrication with full-flow filter
  • Reduces engine wear by ensuring proper lubrication, even when operating on hillsides or uneven terrain
  • Filtered oil reduces risk of contamination for increased engine life for increased engine life
  • Oil cooler helps keep engine at optimum temperature
• Air-cooled engine design for minimum maintenance and maximum reliability
• Standard cleanout ports for easy access to remove debris collecting in cooling fins
• Aluminum cylinder block
  • Effectively dissipates heat
  • Lightweight and strong construction
  • Extends engine life due to elimination of debilitating engine temperatures

M and R Series QuikTrak™ Mowers have 7Iron PRO Mower Decks that are built to last, while delivering a high-quality cut in diverse conditions.

The mower deck shell is forged from a single sheet of 7-gauge, 0.179-in. (4.6-mm) steel. There are fewer welds to wear or break than shells built from multiple fabrications.

Rectangular leading-edge reinforcement and rounded corners help distribute impact stress to reduce potential for damage when the mower contacts trees, rocks, curbs, and other fixed obstacles.

The trim edge of the deck is equipped with a bumper that provides extra abrasion resistance to protect the machine and the property.

Three 1-in. (2.5-cm) cold-forged spindle shafts are heat-treated for strength and supported by ball bearings. Deep spindle pockets keep the blades aligned, even after years of tough operation. The ribbed spindle housings are made of aluminum and have an 8-in. (20-cm) base for added strength and heat dissipation.

M and R Series QuikTrak™ Mowers have a spacious operator platform designed to keep operators comfortable and improve stability, while providing storage.

Moving is essential for operator ergonomics, so the M and R Series QuikTrak Mowers are equipped with a 24-in. (61-cm) wide foot platform that gives the operator room to vary their stance. The fender-mounted foot holds on R Series Mowers enable an even wider range of stance options.

Smooths out the bumps

The platform is spring loaded to keep bumps from jarring the operator. Large tires help isolate the operator from rough ground as well. R Series Mowers include a rubber mat on the foot platform.

Keeps the operator at center of control

The forward pitch of the new M and R Series leaning pad centers the operator’s core over the vehicles center of rotation. This location has the least centrifugal force, keeping the operator stable and in control. The leaning pad is padded for comfort and bolstered to provide side support to the operator while traversing uneven terrain and during end-of-pass turns. The leaning pad on R Series includes extra bolstering and a color accent.

Traction when you need it

The wide foot platform gives the operator the freedom to shift their weight from side-to-side on uneven terrain. Similarly, the forward-pitched leaning pad allows the operator to lean forward to increase stability or lean rearward to increase traction.

The color coded and logically placed controls on M and R Series QuikTrak Mowers are designed to get new operators up to speed quickly. A display panel assists in operating the mower and alerts operators of problems, to reduce downtime and repair costs. The key, choke (carbureted models only), throttle, and power take-off (PTO) switch are located at the operator’s fingertips.

Precise drive controls

Ground speed and direction are easily controlled by moving the two hand-lever hydrostatic drive controls forward or reverse.

• Up to 10 mph (16.1 km/h) forward and 5 mph (8.0 km/h) reverse on M Series Mowers.
• Up to 12 mph (19.3 km/h) forward and 6 mph (9.7 km/h) reverse on R Series Mowers.

Front and rear stationary reference bars stabilize the operator’s hands, which maintains precise control as the mower changes speed or direction. The bars also reduce fatigue from control lever operation.

Control levers return to neutral automatically, and a positive neutral-lock holds the control levers in neutral when the park brake is engaged.
