Central Tractor

GR60, GR72, GR84

The Rhino© Gyro family of heavy-duty rotary cutters has earned, for nearly 50 years, the reputation of outstanding performance and longevity in shredding stalks, cutting grass and weeds, and cutting brush.

Premium components including heavy-duty 44R drivelines (35R GR60); precision-built, heavy-duty gearboxes; and a massive Gyro bar blade carrier are the reason Gyro cutters set the standard all others are compared to.

	Optional Dual Shredding Blades and Shredding Attachment: The optional dual shredding blade consists of two more free-swinging blades to provide additional cutting surfaces. They are ideal of use while shredding prunings in orchards and groves. The optional shredding attachment includes two stationary blades, and when used with the dual shredding blades, provides finer shredding of stalks and grass materials. The result is faster decomposition and nutrient return to the soil.
	Heavy-duty Gearbox and Slip Clutch: The GR 60 has a Cat 4 (35R) driveline, while the GR72 and GR84 have a Cat 5 (44R) driveline for dependable service. The 140 HP gearbox (GR60) and the 150 HP (GR72, GR84) are designed for use on 540 RPM tractors. The gearbox and driveline are protected from sudden shock loads by a heavy-duty slip clutch. Accessing the grease fitting on the driveline yoke is easy with the flip up gearbox shield.
	Heavy-Duty Bar Blade Carrier: The massive heat-treated Gyro blade carrier provides a flywheel effect which lowers the cost of operation by reducing the required horsepower. The 1/2' x 5' heavy-duty flat blades are reversible for longer wear life. The 3/16' deck is reinforced with a formed channel to support the massive gearbox and blade carrier in extreme conditions.

GR60

The GR60 features a heavy-duty 140 HP gearbox. The gearbox is mounted to the formed channel, not the deck. The frame is continuously welded tot he 3/16' deck, for excellent strength. The GR60 is ideal for tractors as small as 30 HP with adequate front weights and is rated for material up to 4' in diameter. Front and rear chain guards are standard on the Gyro single spindle cutters.

GR72

The GR72 requires only a 40 HP tractor with adequate front weights and is rated for material up to 4' in diameter. The 150 HP gearbox, replaceable skid shoes, heat -treated reversible blades, heavy-duty blade carrier and laminated tailwheel all add durability and reduce downtime. The flexible "A" frame is designed to provide flotation on uneven terrain.

GR84

The GR84 features a heavy-duty 150 HP gearbox and is available with a heavy-duty CATII-III Q.H. or pull type hitch to fit a range of tractors. The heavy-duty side skirts, deck, and blade carrier allow the GR84 to cut material up to 4 1/2' in diameter. The GR84 is available in a pull type unity which only requires a 30 HP tractor for efficient operation.
