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.

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. This rotating action absorbs the peak force experienced when an operator strikes an object, protecting the main deck and frame components so you have less down time and more productivity.

Robust Gearboxes

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

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.

Durable Spindles

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.

Dual Rollers

The two full width rollers on the front and rear of each deck help deliver an exceptional quality of cut. The front roller help reduce scalping in undulated terrain while the rear roller 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.

The Groundsmaster 1200 wing decks fold up near vertical for a narrow 86" (218.4cm) 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.
