• 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.
