Page 63: Tractor Horsepower
The power required to operate a mower is determined by the tractor PTO horsepower. For most mowing conditions, the RX60 mower requires a tractor with at least 35 HP, the RX72 mower requires a tractor with at least 45 HP and the RX84 mower requires a tractor with at least 65 HP. Operating the mower with a tractor that does not have adequate power may damage the tractor engine.
Page 64: Drawbar-Pull Type Mower
OPERATION 2.6 Drawbar-Pull Type Mower For equipment operating at 540 RPM, the tractor drawbar must be positioned at a 14” distance from the hitch point to the PTO shaft end for proper operation and minimal wear to the driveline. If attaching the mower tongue clevis to a 3-point hitch drawbar supported by the lower lift arms, the attaching point must be extended past the main bar to allow for turning without binding the clevis and bar.
Page 65: Tire Spacing
OPERATION DO NOT use a PTO adapter to attach a non-matching Implement driveline to a Tractor PTO. Use of an adapter can double the operating speed of the Implement resulting in excessive vibration, thrown objects, and blade and implement failure. Adapter use will also change the working length of the driveline exposing unshielded driveline areas.

Page 89: Raising The Mower
OPERATION 9.3 Raising the Mower Using the tractor 3-point hitch control lever, raise the mower off the ground about 6”, or just high enough to clear any ground obstacles. When raising the mower, make sure all connection points are securely attached and at least 1” clearance is maintained between the driveline and the deck.
Page 90: Crossing Ditches And Steep Inclines
OPERATION 9.5 Crossing Ditches and Steep Inclines When crossing ditches with steep banks or going up sharp inclines, it is possible that the main driveline inner profile will penetrate into the outer housing to its maximum depth until the assembly becomes solid (driveline is at its extreme shortest length).
Page 91: Operating The Tractor And Implement
OPERATION Inclines and ditches should be approached along a line which is at an angle as shown. This type of path will reduce the possibility of over-collapse of the driveline and resulting damage. If the gradient is so steep that such an approach increases the possibility of a tractor roll-over, select an alternate crossing path.
Page 92: Foreign Debris Hazards
OPERATION Many varied objects, such as wire, cable, rope, or chains, can become entangled in the operating parts of the mower head. These items could then swing outside the housing at greater velocities than the blades. Such a situation is extremely hazardous and could result in serious injury or even death.
Page 93: Engaging The Power Take Off (Pto)
OPERATION Rotary Mowers are capable under adverse conditions of throwing objects for great distances (300 ft (100 m) or more) and causing serious injury or death. Follow safety messages carefully. STOP MOWING IF PASSERSBY ARE WITHIN 300 Feet (100 m) UNLESS: -Front and Rear Deflectors, Chain Guards, or Bands are installed and in good, workable condition;...
Page 94: Pto Rpm And Ground Speed
OPERATION 10.4 PTO RPM and Ground Speed Ground speed for mowing will depend upon the height, type, and density of vegetation to be cut. Recommended speed for efficient mower performance is between 2 and 5 mph(3-8 kph). Operate the mower at its full rated PTO speed to maintain blade speed for a clean cut.
Page 95: Cutting Material
OPERATION 10.6 Cutting Material When cutting trees and brush approach material to be cut with the head perpendicular to the material. The cutting edge of the blades should be the only elements in contact with material. The blade bar should not contact the material. Material should be fed through the head rather than the head being lowered on top of material.
Page 96 OPERATION Follow these guidelines to reduce the risk of equipment and grass fires while operating, servicing, and repairing the Mower and Tractor: -Equip the Tractor with a fire extinguisher in an accesible location. -Do Not operate the Mower on a Tractor with an underframe exhaust. -Do Not smoke or have an open flame near the Mower and Tractor.
Page 97 OPERATION Large, dense, or wet vegetation may need to be mowed in two or more passes to achieve a uniform cut. In such conditions, raise the cutting height to 12” or more on the first pass OPS-R-0043 Then lower the mower to the desired height and mow the vegetation a second time.
Page 98: Right Of Way (Highway) Mowing
OPERATION 10.7 Right of Way (Highway) Mowing Do not mow, or drive the tractor into material that is burning, or areas that recently burnt and may contain hot spots. Burning material, sparks, and coals could be thrown from the mower to areas of vegetation that might ignite.
