mately 1/4" lower than front to prevent belt from rub- bing on mower.)
Dimension “B” is set by adjusting optional casters or lift chains.
Dimension “A” is set by raising or lowering channel arms in push bars.
IMPORTANT
■Any adjustment to either dimension “A” or “B” will require checking the other adjustment.
Set desired cutting height with casters or lift chains then adjust for dimension “A”.
Check attitude by placing a straight edge along outside edge of mower as shown in Figure 1. Measure from bottom of straight edge to ground. The measurement at dimension “B” should be level with or approximately 1/2" lower than the rear. The measurement at dimen- sion “A” should never be lower than the one at dimen- sion “B” (except when using a leaf mulcher or with some tractor tire configurations, it may be necessary to adjust rear of mower approximately 1/4" lower than front to prevent belt from rubbing on mower.)
To determine cutting height, it is necessary to subtract the distance the blade is below mower from the mea- surement at dimension “B”. Subtract
Be sure mower is level side to side using these mea- surements. If it is not, check to be sure casters are set in same hole, and that channel arms and push bars are set in same hole on each side. Minor adjustments can be made by using slots in rear lift bracket for adjust- ments.
When making cutting height or attitude changes, be sure to check belt alignment. (Refer to Belt Alignment in Assembly section on page 23.)
IMPORTANT
■Improper belt alignment or tension can cause premature belt failure.
Side Skid Adjustment
With cutting height established, adjust side skids at least 1/2" above ground level. Properly adjusted side skids are designed to carry mower over uneven ground and minimize scalping. Never adjust side skids to be in constant contact with ground.
A WARNING
■Allow no children or unqualified persons to operate this equipment.
■Do not operate mower in vicinity of other per- sons.
■Do not allow riders on tractor or mower.
PRE-OPERATION CHECK LIST
___ Check to ensure blades are sharp and secure and cutting edge is positioned in the direction of blade rotation
___ Always operate tractor PTO at 1000 rpm maxi- mum when mowing.
___ Check to make sure all safety shielding is prop- erly installed and is in good condition. Be sure discharge chute or side shield is installed.
___ Check cutting height adjustment.
___ Clear area to be mowed of debris that could be picked up and thrown by mower.
___ Place tractor transmission in neutral and be sure PTO is disengaged before attempting to start tractor engine.
___ Make sure all critical tractor adjustments such as brake and clutch pedal travel, etc., are set to trac- tor manufacturer’s specifications.
STARTING & STOPPING MOWER
Power for operating the mower is supplied by tractor power take off (PTO). Refer to your tractor manual for PTO operating instruction.
A WARNING
■Do not exceed PTO speed of 1000 rpm maxi- mum.
A CAUTION
■Stop mower and tractor immediately upon striking an obstructions. Inspect mower and repair any damage before resuming operation.
Should mower become plugged, causing belt to slip over two seconds, raise mower just enough to clear plug and continue running for at least two minutes, allowing pulleys to cool. Stopping the mower with belt in contact with a very hot pulley will bake and ruin belt. Do not raise mower higher than necessary, to reduce the risk of thrown objects.
Commencing Mowing
When engaging PTO, the engine rpm should always be low. Once engaged and ready to start mowing,
