Adjusting Rollers; Adjusting Deck Pitch - Toro 30385 Operator's Manual

ADJUSTING ROLLERS

Rollers should be located in the upper holes for 2.5 and 3.8
cm heights of cut and lower holes for 5 to 12.7 cm heights
of cut. Five rollers are located on the deck, three under the
main deck and one on each wing.
1. Adjust the rollers by removing the lock nut and bolt,
positioning as desired and then installing the lock nut
and bolt.

ADJUSTING DECK PITCH

Deck pitch is the difference in height of cut from the front of
the blade plane to the back of the blade plane. TORO rec-
ommends a blade pitch of 6.4 mm ,i.e., the back of the blade
plane is .6.4 mm higher than the front.
1. Position the machine on a level surface on the shop
floor.
2. Set the deck to the desired height of cut.
3. Rotate (1) blade so it points straight forward.
4. Using a short ruler, measure from the floor to the front
tip of the blade and remember this dimension. Then,
measure from the floor to the rear tip of the blade.
5. Subtract the front dimension from rear dimension to
calculate the pitch.
6. To adjust pitch, start the tractor and raise the deck to
the highest possible position and turn off the engine.
7. Loosen the jam nuts on the bop or bottom of the height-
of-cut chain U bolt.
8. Adjust the other set of nuts to raise or lower the rear of
the No. 3 chamber and attain the correct deck pitch.
9. Tighten the jam nut.
10. Lower the deck.
