Features

Cutting Deck Protection

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.

Durable Spindles

Ductile cast iron spindle housing is large in diameter [229 mm at the base] to dissipate impact loads. Dual tapered roller bearings last up to six times longer than ball bearings.

Robust Gearboxes

The deck gearboxes include an overrunning clutch that isolates the force from accidental blade impacts to keep the mower and tractor safe.

Dual Rollers

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. Each roller includes heavy duty bearings featuring easy access grease points.

Maximum Productivity

The Groundsmaster 1200 features a deck lift system allowing for the decks to be lifted from the turf while the PTO is engaged to quickly turn around without scuffing or transport over cart paths. This system helps keep the operator running at peak productivity.

Simple Height of Cut Adjustment

The Groundsmaster 1200 is not only a highly productive mower, it's also very versatile. Each deck features four mowing height adjustment points making it simple and quick to deliver the exact mowing height for superior conditions.

Quick Transport

The Groundsmaster 1200 wing decks fold up near vertical for a narrow 218.4 cm (86") transport width making it easy to get from site to site. Additionally, the transport wheels feature a torsion axle delivering a remarkably smooth ride making transport quick and comfortable.
