Resumen del manual
Complete check lists on page 20 when assembly is complete. Position cutter flat and cut the nylon straps that are holding all loose parts to the cutter. Rotate the “A” frame hitch forward and connect lift arms and toplink. Attach the two linkage lift straps to the cutter deck (behind the gearbox) and to the end of the slack link on the “A” frame. These bolted connections are moveable joints – so tighten nylock nuts only until excess looseness is gone. Most swinging drawbars will have to be moved to a forward position or removed. Check the tractor swinging drawbar for interference with the front of the cutter before attempting to lift the cutter with the 3-pt. hitch. Tractor lift arm stabilizer bars or sway blocks must be used to control side movement of the cutter. DO NOT CONNECT THE PTO DRIVELINE AT THIS TIME. Check your lift arm Be sure the hydraulic 3-pt. hitch control draft control is turned off. Adjust lower lift arm(s) to level Refer to tractor operator’s manual for instructions. Cutting height is controlled with tractor and rear tailwheel adjustment. PTO DRIVELINE INSTALLATION Spray WD-40 into the yoke and wipe. This should remove some of the paint and make it easier to slide yoke onto the input shaft of the gearbox. Remove shearbolt and retaining ring (4) from gearbox input shaft (3). Grease the input shaft of the gearbox before installing the PTO shaft. This reduces the chance of the PTO shaft yoke from galling to the input shaft if the shear pin should break. Remove rear drive shield (1) from driveline. To remove, turn each plastic clip 1/ 4 turn and then lift out. Then slide rear shield so entire joint assembly is exposed. (Refer to figure 5.) To prevent seal damage, carefully push driveline onto gearbox input shaft until it contacts gearbox housing. Install retaining ring (4) and then pull driveline ahead. 1. Drive shield 3.

Shear Bolt Driveline Installation NOTE: A grade 2 bolt must be used for the shear bolt to provide gearbox protection. Align the holes in the driveline yoke and gearbox input shaft and install and tighten shear bolt (6) and nut (5). Install rear drive shield to driveline. Lubricate rear driveline half and install front driveline half. 19 OPERATING GEARBOX OIL NOTE: The gearbox is shipped WITHOUT lubricant, so it will be necessary to fill is before a level position, fill to the side inspection 90 wt. gear lubricant. Check often and necessary. GENERAL SAFETY Only qualified people familiar with this manual should operate this machine. Operator should wear hard hat, safety glasses, and safety shoes. It is recommended that tractor be equipped with Roll-Over Protective System (ROPS) and a seat belt be used. Before beginning operation, clear work area of objects that may be picked up and thrown. Check for ditches, stumps, holes, or other obstacles that could upset tractor or damage cutter. Always turn off tractor engine, set parking brake, lower cutter to ground and allow cutter blades to come to a complete stop before dismounting tractor. Safety is a primary concern in the design and manufacture of our products. Unfortunately, our efforts to provide safe equipment can be wiped out by a single careless act of an operator. It has been said, “The best safety device is an informed, careful operator”. We ask you to be that kind of an operator. The designed and tested safety of this machine depends on it being operated within the limitations as explained in this manual. Be familiar with and follow all safety rules in the manual, on the cutter and on the tractor. The safe operation of this machine is the responsibility of the owner/operator. The operator should be familiar with the cutter and tractor and all safety practices before starting operation. Read the safety rules on pages 4 thru 14. CAUTION! Do not operate the PTO at other than the rated 540 RPM. Excessive speeds can cause breakage, thrown objects, and potential injury. ADJUSTING FOR WORK The cutter should be operated at the highest position which will give desired cutting results. This will help prevent the blades from striking the ground, reducing blade wear and undue strain on the machine. For best results always tilt the cutter slightly This tilt decreases horsepower requirements. is desired, adjust cutter This will keep the foliage under shredded. More power is required The cutting height is adjustable from To adjust, proceed as follows: A. Raise cutter off ground using tractor 3-point lift. Turn off tractor engine, disengage PTO, set parking brake, and remove key from ignition. B. SECURELY BLOCK CUTTER. C. Remove bolt securing tailwheel to adjusting strap. D. Adjust tailwheel to desired position. Secure with bolt, lockwasher and nut. E. Lower cutter to work position. F. Adjust tractor 3-point hitch top link so linkage lift straps have a small amount of slack to allow cutter deck to float during operation. PR...
