Correcting Mower Deck
Mismatch
If the cut is uneven across the mower swath,
correct it as follows:
1. Position the machine on a level surface on the
shop floor.
2. Set the cutting unit to the desired height of cut,
move the throttle lever to the Slow position,
stop the engine, set the parking brake, and
remove the ignition key.
3. Check and adjust front and rear tractor tire
pressure; refer to Checking Tire Pressure in
Drive System Maintenance, page 52.
4. Check for bent blades.
5. Remove the covers from the top of the cutting
units.
6. Rotate the blade on each spindle until the ends
face forward and backward.
7. Measure from the floor to the front tip of the
cutting edge.
8. Adjust the jam nuts securing the deck
yokes/chains to the mower deck until the
mower deck is level.

Adjusting the Mower Deck
Pitch
Cutting unit pitch is the difference in height-of-cut
from the front of the blade plane to the back of
the blade plane. Toro recommends a blade pitch
of approximately 5/16 inch (8 mm). That is the
back of the blade plane is 5/16 inch (8 mm) higher
than the front.
1. Position the machine on a level surface on the
shop floor.
2. Set the cutting unit to the desired height-of-cut,
move the throttle lever to the Slow position,
stop the engine, set the parking brake, and
remove the ignition key.
3. Rotate the center blade so that it points straight
forward.
4. Using a short ruler, measure from the floor to
the front tip of the blade.
5. Rotate the same blade tip to the rear and
measure from the floor to the tip of the blade
at the rear of the deck.
