QuikTrak™ mower deck (652R shown)

Mower-deck reinforcement (652R shown)

A well-designed mower deck can make the difference between just getting the job done and getting eye-catching results. The 7-gauge, 0.179-in. (4.6-mm) fabricated mower deck delivers a higher quality of cut in more diverse conditions to enhance mowing performance.

Key features of the fabricated mower deck include: 

• The mower deck is manufactured from 7-gauge, 0.179-in. (4.6-mm) steel to minimize the number of welds and provide a smooth underside, with fewer sharp corners, for reduced material buildup.
• A compact footprint delivers greater maneuverability when working in tight quarters.
• A deep-deck design delivers excellent airflow so material is processed quickly and efficiently.
• A powerful vacuum effect is created by the deck's unique air-flow design, which pulls more grass upright so that the blades can cut more evenly.
• 48-in. to 61-in. (122-cm to 155-cm) decks come standard with an adjustable striping flap to enhance the after-cut appearance.

Flexible mower-discharge deflector

Large, inset caster wheels

The wide-discharge opening and raised deflector provide even clipping dispersal for an excellent finished appearance in all conditions.

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 recessed to reduce the 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 damage.

Anti-scalp rollers are double-captured for durability. They enable the deck to float over the ground and provide a smooth, level cut on even the most challenging terrain.

Mower lift lever
