BLADE BRUSH ADJUSTMENT
The blade brush is properly set when machine leaves the factory, but it wears out during operation and needs to be
readjusted periodically. The blade brush assembly is found behind the drive side door and is shown below. To adjust the
assembly, loosen the hex nut, turn the setscrew counterclockwise until the wires on the brush touch the bottom of the
blade gullets and tighten the hex nut.
The brush should be replaced as it becomes worn to approximately 70% of it’s original 3” diameter. Replacements can be
purchased through your Hyd·Mech Dealer.
BLADE TRACKING ADJUSTMENT
For an H-18, blade tracking is set so the teeth of the blade protrude .260±.01” (6.6±.25mm) from the face of the wheels.
For an H-22, blade tracking is set so the teeth of the blade protrude .310±.01” (6.6±.25mm) from the face of the wheels.
IDLER WHEEL TRACKING
Release blade tension before adjusting. Adjust tracking by regulating “push” set screws and “pull” bolts. Loosening bolts
“A” and turning in set screws “C” by equal amounts will move the blade OFF the wheel. Loosening bolts “B” and turning in
set screws “D” by equal amounts will move the blade ON to the wheel. After each “C” or “D” set screw adjustment, tighten
bolts “A” or “B”, turn tension switch to “+RUN”, run the
blade for a moment and recheck the tracking.
Note: Check the proximity sensor distance from the wheel
target or spokes before starting the blade drive. Failure to
do so may result in damage to the sensor.
