Floating Deck Hydro Drive

  • 52" (132 cm) TURBO FORCE 7-gauge cutting deck
  • 18.5 hp* Kawasaki® 603cc engine
  • Hydro-Gear 10cc pumps and Parker motors
  • Robust 9-3/8" cast iron spindles

18.5 hp Kawasaki® 603cc engine with 52" TURBO FORCE cutting deck, Twin-Lever steering controls.

Patented Adjustable Baffle

Allows operator to achieve maximum cutting performance by fine-tuning deck to conquer changing conditions, unique job sites or different times of the season. In extreme conditions, the baffle can be opened in order to conserve power and achieve faster mowing speeds. In less demanding conditions, the baffle can be closed to yield micro-sized particles and maximize discharge velocity.

Commercial-grade Deck Construction

The 7-gauge deck shell is further reinforced by a bull-nose front bumper, a 1/2" (1.3 cm) thick wear guard on the trim side, and a 3/8" (1 cm) thick reinforcement plate around the discharge opening.

Flat-free Caster Tires

Semi-pneumatic flat-free caster tires decrease downtime by eliminating flats.

Walk-Behind Bags

Toro® utility bags add convenience and productivity to everyday mowing. Use them for trash, tools, cell phone - whatever you need to pick up or carry with you.

Atomic® Mulching Blades

Atomic® mulching blades feature an aggressive "tooth" design that shreds grass and leaves into small particles. The teeth curl upward behind the blade to suspend clippings in the chamber so they are cut and re-cut until they virtually disappear.

Recycler® Mulching Kits

Recycler mulching kits deliver the industry's finest mulching performance and reduce mowing time up to 38% vs. bagging*.

*Respondents in a Texas A&M University study cut their lawns 38% faster when they didn't bag.


Toro's patented TRU TRAK® sulky is the industry's most innovative sulky design. Large, independently pivoting foot plates greatly reduce operator fatigue while the 2-point connection eliminates jack-knifing in turns or reverse. The unit tracks "true" and straight every time. Foot pads pivot into stowed position when operating in conditions not conducive to sulky operation and for trailering convenience.
