Key Features

  • The Toro bi-directional impact absorption system was designed for an impact of 5 mph. The spring-loaded cylinder allows the deck to rotate upon impact, which absorbs the force and protects the mowing decks and main frame components from damage, enhancing productivity.
  • Ductile cast iron spindle housing is large in diameter [9 in. (229 mm) at the base] to dissipate impact loads. Dual tapered roller bearings last up to six times longer than ball bearings.
  • The deck gearboxes include an overrunning clutch that isolates the force from accidental blade impacts to keep the mower and tractor safe.
  • The two full width rollers on the front and rear of each deck help deliver an exceptional quality of cut. The front rollers help reduce scalping in undulated terrain while the rear rollers delivers the exceptional turf striping.

The Only Pull-Behind Worthy of Being a Groundsmaster.

The Groundsmaster 1200 delivers an unparalleled combination of productivity, durability and superior cut. It features a 12-foot (3.7 meters) width of cut and can mow up to 8.73 acres/h (3.53 hectares/h) at 6 mph (9.7 km/h) per hour. Remaining true to Groundsmaster’s unmatched reputation of durability, the 1200 was designed for years of reliable mowing. Its spindles are the same as Toro’s large rotaries and capable of withstanding the roughest conditions. The bi-directional impact resistant system provides additional protection to the wing decks. Don’t let its productivity and robust design fool you; the Groundsmaster 1200’s independently articulating decks hug undulations for an exceptional finish. Combine this with the dual roller design, the Groundsmaster 1200 delivers a high-quality cut and rich turf striping in most conditions.

Productivity, durability and exceptional cut. That’s what makes the 1200 the only pull behind worthy of being a Groundsmaster.
