DECK LEVELING
a) Park the machine on a smooth, level surface.
Raise the deck to the transport position.
b) Lower the deck onto a pair of equal height blocks
A under the rear corners of the deck. Place
another pair of adjustable blocks B under the
front of the deck so that the deck top is pitched
forward 1/8".
A 1/8" forward pitched deck provides the best horse-
power.
A level deck provides the best quality of cut.
A 1/8" rearward pitched deck provides the best strip-
ing.
Certain grass types and conditions may vary.
NOTE: The front and rear of the deck are at different
heights.
c) Measure the height of the blade cutting edge
above the ground. Remove pin C and set the
height of cut lever D to that height.
d) Loosen nuts I at all four corners of the deck.
NOTE: This will relieve tension on chains H.
e) Loosen the jam nuts E on the height of cut clips
F and adjusting screws G. Turn the adjusting
screws G until the play is taken out of the chains
H at all four corners. Tighten the jam nuts E
against the clips F and at the adjusting screws G.
Retighten nuts I at this time.
COUNTERBALANCE SPRINGS
1. Raise the cutterdeck all the way.
2. Adjust the spring A with nut B: The spring length
should be set at approximately 8-3/4", inside loop
to inside loop, when in transport position.
The springs may be tightened or loosened from
this point according to personal preference.
