RC5715 & RCM5715 Rotary Cutters 331-431M

Level Center & Wing Decks
These adjustments should be made with your cutter
hooked to the tractor operating the cutter or to a tractor
having the same drawbar height.
Level Center Deck
Refer to Figure 2-3 & Figure 2-4 on page 34:
1. With cutter hooked to a tractor, disengage power
take-off, and park on a level, hard surface. Place
tractor gear selector in park or set park brake.
2. Using hydraulic lift, adjust center deck height so that
front skid shoes (#10) are 2 to 3 inches above
ground.
3. Wait for blades to come to a complete stop and then
fold wings up to the transport position.
4. Shut tractor down before dismounting according to
5. Lock wings in the folded-up position with transport
pins. Refer to
6. On both sides of the center deck are continuous
hinges (#1). Measure distance from bottom of hinges
to the ground at the front and back. The hinges
should be equal distance off the ground at the back
and 1" closer to the ground at the front.
If continuous hinges are too high at the front:
a. Remove cotter pins (#3).
b. Unscrew adjusting nuts (#4) an equal amount to
lower the front of the cutter until both hinges are
1" lower at the front than at the back.
If continuous hinges are too low at the front:
a. Remove cotter pins (#3).
b. Tighten adjusting nuts (#4) an equal amount to
raise the front of the cutter until both hinges are
1" lower at the front than at the back.
7.
Be sure the left and right leveling rods have equal
amounts of tension and then replace hairpin
cotters (#3). Bend one or more legs of each cotter pin
to keep them from falling out.
IMPORTANT:
See
. Loosening adjusting
nuts (#4) will lengthen leveling rods and lower front
of cutter. Tightening adjusting nuts (#4) will shorten
leveling rods and raise front of cutter.
NOTE:
The 1" measurement can be increased or
decreased depending on cutting conditions.
Level Wing Decks
Refer to Figure 2-3 on page 34:
Each wing section will need adjusting if the outer edge of
the wing top is not level with the top of the center deck.
1. Start tractor and lower wings down. Refer to
on page 41 for detailed instructions.
2. Pull cutter straight forward six to ten feet to allow the
wheels to properly align themselves.
3. Check wing tops for levelness. If the outer edge of
either wing top is higher or lower than the center
deck, then that wing should be leveled as follows:
a.
If outer wing edge is higher:
Loosen jam
nut (#7) and tighten turnbuckle (#8) to shorten the
turnbuckle until the outer wing edge is level with
the top of the center deck. Tighten jam nut (#7) to
the correct torque when level.
b.
If outer wing edge is lower:
Loosen jam
nut (#7) and loosen turnbuckle (#8) to lengthen
the turnbuckle until the outer wing edge is level
with the top of the center deck. Tighten jam
nut (#7) to the correct torque when level.
