Figure 1. Attitude Adjustment
NOTICE
■Improper belt alignment or tension can cause premature belt failure.
Lubrication
Grease caster pivot and wheel every 8 hours of opera- tion.
There are grease fittings on each of the three blade spindles, which are accessible without shield removal. Grease every 24 hours of operation with a good grade light to medium grease gun.
NOTICE
■Do not over grease spindles. Excess grease could be transferred to the belt and cause slippage or premature failure.
Belt Tension (Figure 2)
Set belt tension using a spring scale or other force measuring device. Remove left belt shield. Attach scale between center and left pulley. Apply between 3 and 4 pounds of force. Belt deflection should measure 5/16" for normal conditions.
Tension may be increased if necessary to prevent belt from slipping in heavy mowing conditions. When checking tension without a force measuring device, the belt, when properly set, should feel very tight.
Cycle belt through at least two revolutions after any adjustment before checking tension. These belts are very strong and need to be adjusted very tight. Belts are more likely to be damaged by excessive slippage than from being overtightened.
NOTICE
■Belt must not rub deck or crosswise support.
Tension adjustments may be made by moving the idler pulleys up or down.
Figure 2. Proper Belt Tension
NOTICE
■Alignment must be rechecked if it is necessary to move idler pulleys to get proper belt tension.
■Tension on a new belt should be readjusted every half hour for the first two hours and then checked every 8 hours of operation.
Side Shield & Discharge Chute
Side shield and discharge chute are provided for dis- charge end of mower (left end on white frames and right end on yellow frames). Use side shield for normal mowing and in areas where other persons may be present. Use discharge chute for very heavy mowing conditions.
NOTICE
■Always use either side shield or discharge chute.
Optional Equipment
Optional equipment available for this equipment includes casters for cutting height control, front roller to minimize scalping, low and extra suction blades, and a leaf mulcher. Low suction blades are for sandy areas where abrasive action could cause excessive blade wear. Extra suction blades are designed to lift up fragile downed grasses for better cutting results and are also recommended for use with leaf mulcher attachments.
Mower Spindle Assemblies
Mower spindle assemblies are equipped with two tapered roller bearings. Bearing adjustment is held by a roll pin. Adjustment should not be necessary. Repair requires special skills and tools. You may save time and money by using a new spindle assembly.
