Tire and Skid Assembly Installation
Refer to parts drawing on page 38.
The mower is shipped with skids assembled to rear corners.
If tires and wheels are used, assemble the solid lami- nated tire (24) to cutter frame with one lock washer (62), and secure with one 1" NF hex nut (61).
If skids are used instead of wheels, install two 3/4 x
Tires or skids may be adjusted up or down for desired mowing height. Cutter should be adjusted so rear outer skid does not carry any weight under normal conditions as it encounters considerable side slipping action when turning. The inner side skid should be adjusted to pre- vent cutter from scalping, but so it does not ride on the ground in normal mowing.
Adjust front skids so they prevent scalping and so they will carry cutter when the tractor goes through a low spot. When skids are used, the weight of the cutter should be carried on the tractor and not on skids or rapid wear will result. After desired height has been selected, bolt left and right wheel guards in place. Secure with 1/2 x
Lubrication
Fill both center and cutter gearboxes half full of 90 EP gear lube or similar transmission oil. These boxes are sealed. If there is no leakage, only occasional oil checks are required.
Check for leaks in the hydraulic system. On cutter gearbox, remove top plug and replace with special vented pipe plug from box of parts.
Checking the Machine
Raise and lower the
Raise and lower cutter frame very carefully, being sure none of the bolt heads interfere with drive linkage, etc., and that drive shaft slides freely and works properly. Cutter should raise to approximately a vertical position.
Start cutter slowly and be sure blades don't interfere with anything. The drive must operate smoothly and freely. Now raise and lower the cutter slowly with drive shaft turning and again check for interferences or prob- lems.
Adjust so center frame and cutter frame ride with front slightly lower than rear for normal mowing. For varia- tions, see instructions in Operation section.
Reinstall the shield on the cutter.
Chain Shielding Installation
Full chain shielding must be installed when operating in populated areas or other areas where thrown objects could injure people or damage property.
•If this machine is not equipped with full chain shielding, operation must be stopped when any- one comes within 300 feet (92 m).
•This shielding is designed to reduce the risk of thrown objects. The mower deck and protec- tive devices cannot prevent all objects from escaping the blade enclosure in every mowing condition. It is possible for objects to ricochet and escape, traveling as much as 300 feet (92 m).
Chain shielding is bolted to front and rear of cutter with a 1/2 x
Check Chain Installation
Check chains are used to act as lower limit stops when lowering center frame. They will also prevent the cutter from settling when tractor hydraulic system will not hold the load on the
To install, bolt end of chain to diagonal brace of
It may be necessary to replace top link pivot pins with long 3/4 x 6" bolt provided. Adjust chains as required to carry cutter at desired height and angle.
Counterweight Installation (Optional)
This cutter throws a considerable side load on the 3- point hitch which results in torsion in cross shaft of trac- tor. If tractor has a fairly small cross shaft, it is advis- able to use a counterweight on the left of center frame. This counterweight, as provided, weighs 400 lbs and bolts in place as shown on page 36. Also “suitcase” weights may be used in place of the counterweight box. Use as many as required to attain the 400 lbs counter- weight. An empty counterweight box may also be pur- chased which, if filled with steel punch slugs, will weigh approximately 400 lbs. Use at least 400 lbs; more weight will not be harmful to the machine and may be of some help.
