• Durability and mowing performance from 7Iron™ PRO Mower Decks forged from a single piece of steel

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.

EXCEPTIONAL MOWING RESULTS

• Spacious operator platform gives operators room to move

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.

• Get operators up to speed with user-friendly controls

OVERVIEW

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.

• Exclusive three-year, bumper-to-bumper warranty is standard with a QuikTrak™ Mower

HASSLE-FREE THREE-YEAR WARRANTIES

The E and M Series QuikTrak mowers have a 1200-hour or 36-month, whichever comes first, bumper-to-bumper warranty. The R Series mowers have a 1500-hour or 36-month, whichever comes first, warranty.
