TROUBLESHOOTING

1. Be sure unit is properly adjusted and attached to tractor.

2. Remove mower from tractor and clean all grass clippings and material front mower housing to assure proper balance of unit.

3. Rotate blade and see that all blade ends are level with each other, and will cut even and on a horizontal plane.

4.  Check blade conditions - may need to be sharpened.

5. Check curved baffle plate to see it is riot bent or damaged.

6. Check mower and PTO drive belt for proper adjustments and tension.

7. For some mowing conditions, it may be advisable to use a ground speed reduction group. There is a 10" transmission drive pulley and belt available for field installation. The 8" pulley and belt normally used for the tiller can be obtained from Parts.  By slowing the ground speed and maintaining rotor speed will produce better mowing job.

8. The mower is designed to cut from 2" to 3" for lawn work. A better looking lawn and best care for grass is maintained by cutting often and not too short.  A mower set for a 2" cut on a hard surface will be very short due to the tendency to ride down the grass stubble.

9. With the mower working behind the travel of. the tractor front wheels, it may be necessary to over-cut the width of the wheel mark in the mowed grass. This would leave no uncut grass for best appearance on estate lawns, etc.

10. If mower is properly adjusted and in apparent good condition, but seems to require excess engine power - check all blade drive assemblies.  The rotor spindles should turn with 1" to 2" lbs. pull.  This can be checked by removing mower drive belt shield and drive belt.  If this pull is up to 5" lb. or more, the unit will rob power from the tractor. Repair or replace necessary parts of the rotor spindle assembly. Tight bearings, bent rotor shafts or spindle housings may be caused by hitting obstructions.

* NOTE:  The earliest 42" decks did not use the Spring to tension the belt, but used a slot in the deck where the idler pulley shaft could be loosened and adjusted.
