Adjusting the Cutting Unit
Pitch
Measuring the Cutting Unit Pitch
Cutting unit pitc h is the difference in height-of-cut
from the front of the blade plane to the bac k of
the blade plane . T oro recommends a blade pitc h
of 1/4 inc h (6 mm). T hat is the bac k of the blade
plane is 1/4 inc h (6 mm) higher than the front.
1. P osition the mac hine on a lev el surface on the
shop floor .
2. Set the cutting unit to the desired height-of-cut.
3. R otate 1 blade so that it points straight forw ard.
4. Using a shor t r uler , measure from the floor to
the front tip of the blade . R otate the blade tip
to the rear and measure from the floor to the
tip of the blade .
5. Subtract the front dimension from the rear
dimension to calculate the blade pitc h.
Adjusting the Front Cutting Unit
1. Loosen the jam n uts on the top or bottom of
the height-of-cut c hain U-bolt ( Figure 86 ).
2. Adjust the other set of n uts to raise or lo w er
the rear of the cutting unit and attain the
cor rect cutting unit pitc h.
3. Tighten the jam n uts .

Adjusting the Side Cutting Units
1. R emo v e the tensioning cap from the spindle
shaft and slide the spindle out of the castor
ar m ( Figure 87 ). R e position the shims , as
required, to raise or lo w er the castor wheel
until the cutting unit has the cor rect pitc h.
