Woods BATWING BW20.51Q Operator's Manual page 15

1. Check tongue clevis to make sure it is adjusted to
match your tractor PTO speed.
2. Position tongue clevis (A) up or down based on trac-
tor drawbar height.
3. Attach cutter using a 1-1/8" clevis pin (1) and clip.
4. Attach safety tow chain (2) to drawbar support.
Leave enough slack for turning.
5. Connect cutter driveline to tractor PTO shaft, mak-
ing sure the spring-activated lock pin slides freely
and is seated in tractor PTO splined groove.
6. Remove parking jack (3) from the tongue and attach
it to the storage post on the front of the left wing.
7. Adjust nuts (4) so tongue clevis (A) is parallel with
the tractor drawbar.
8. Remove parking jack (3) from the tongue and attach
it to the storage post on the front of the left wing.
NOTE: Place driveline in storage position on the
hose holder (5) when not in use.
Hydraulic Connection
1. Inspect hydraulic hoses to ensure they are in good
condition.
2. Clean the fittings before connecting them to the
tractor hydraulic ports.
3. Route the hose through the hose holder at the hitch
and be sure the hose can slide freely in the holder.
Do not allow hose slack to drag on the ground or
become caught on tractor protrusions.
4. Attach the hydraulic hose to the tractor.
5. Raise unit with center lift cylinder and extend wing
cylinders. Stop tractor and remove transport lock
pins from wing stops and transport stop as shown in
Figure 2 and Figure 3, page 18.
6. From the operator position, start tractor and raise
and lower deck several times to purge trapped air
from the hydraulic cylinder.
Interference Check
1. Be sure that tractor 3-point lift links do not inter-
fere with hydraulic hoses, cutter driveline, or cutter
frame.
2. Check for straight-ahead operation and at full turn-
ing angles. If there is any interference, remove the
lower lift links.
3. Contact between tractor lift links and cutter parts
can cause damage, especially when turning.

CV Driveline Turning Limits
NOTICE
■ You must not exceed a turning angle of 80 de-
grees at the head of the Constant Velocity
driveline or damage will occur.
1. To check for potential excessive turn angle, discon-
nect the driveline from tractor.
2. Start engine and turn as far right or left as possible.
3. Shut engine off and try to connect CV driveline to
tractor. If it cannot be connected, the turn angle is
too severe.
4. Restart engine and straighten angle slightly, shut off
engine and try to connect CV driveline to tractor.
5. Repeat the process until the driveline can be con-
nected. The point at which the driveline can be
connected is the maximum turn that should be
made.
Cutting Height Adjustment
NOTICE
■ Avoid ground contact with blades. Striking
ground with blades produces one of the most
damaging shock loads a cutter can encounter. If
this occurs repeatedly, the cutter, driveline, and
gearboxes will be damaged.
Cutting height range is from 2" to 15". A hydraulic cylin-
der is used for cutting height adjustment.
When selecting a cutting height, you should consider
the area of operation. If the ground is rolling and has
mounds the blades could contact, set the cutting height
accordingly. The cutting height (blade edge) is approxi-
mately 1" above the bottom of the side skid.
Cutting Height (Normal Mowing) - Center Section
1. Position the cutter on a hard level surface and se-
lect an approximate cutting height, Example 6".
2. Raise wings and lock them in the UP position.
3. Use the hydraulic cylinder to raise or lower the cen-
ter section to obtain a distance of 5" from bottom
edge of skid shoe to the ground.
4. Place jackstands under the four corners of the cen-
ter section. See illustration on page 21. Lower center
section to relieve pressure on attitude rod nuts.
5. Loosen outer jam nut on the attitude rods.
6. Adjust inner nuts in or out until the rear of the cut-
ter is approximately 1/2" higher than the front. See
Figure 1A. It's used as a starting point for adjusting
the attitude rod, based on different tongue height
and wheel options.
