2-1 ATTACHING TO TRACTOR
IMPORTANT
(540 RPM only)
The minimum required PTO horsepower is 30 HP
for the TD-1100.
A. Adjust tractor drawbar length to dimension
shown in Figure 2-1. Incorrect drawbar length will
change angle of driveline causing possible damage
to constant velocity joint. See tractor operator’s man-
ual for drawbar adjustment procedure.
WARNING
NEVER STAND BETWEEN TRACTOR
AND MOWER WHILE TRACTOR IS
BEING BACKED TO HITCH.

E. Connect hydraulic hose to tractor remote
quick couplers.(See tractor dealer if furnished cou-
plers are not correct for your particular tractor) Make
sure hydraulic line is not twisted or kinked.

USE A PIECE OF CARDBOARD OR WOOD
RATHER THAN HANDS AND WEAR EYE PRO-
TECTION WHEN SEARCHING FOR HYDRAULIC
LEAKS. ESCAPING HYDRAULIC OIL UNDER
PRESSURE CAN PENETRATE SKIN. IF OIL IS
INJECTED INTO SKIN, IT MUST BE SURGICALLY
REMOVED WITHIN A FEW HOURS OR
GANGRENE MAY RESULT.
1 inch (25mm) diameter approved pin with lynch pin
retainer or equivalent.
D. Adjust tongue and clevis angle as necessary
to keep mower frame level with ground when
attached to drawbar. (Figure 2-2)
IMPORTANT
PTO ADAPTERS SHOULD NOT BE USED WITH ANY
BUSH HOG EQUIPMENT. FAILURE TO FOLLOW
THESE INSTRUCTIONS WILL CAUSE DRIVELINE
FAILURE AND POSSIBLE TRACTOR DAMAGE.
B. Attach jackstand to frame of cutter. Extend
jackstand to support weight of frame.
C. Connect clevis hitch to tractor drawbar using a

SECTION II
PREPARATION FOR USE
NOTE:
TD-1100 units using standard single acting hydraulic cylinders require tractors which are equipped
with a “float” position in their hydraulic systems to allow the wing decks to follow the contour of the
ground. If your particular model tractor does not have a “float” position in its hydraulic system, a
double acting hydraulic cylinder conversion kit should be installed. See your Bush Hog dealer.
Before operation, service all locations outlined in Section 4-2 “Lubrication” and remove transport
lock pins from mower decks as shown in Figure 3-4. Unpin inside wing tires and reposition into a
trailing position and repin in place. Run-in the mower in a static condition at half throttle for 30 min-
utes. Inspect all belts for proper tension; check gearboxes for proper oil level; and check to make
sure blade spindles are not overheating.
NOTE:
Offset drawbar
must be turned
down as shown.
If after turning the offset draw bar downward, there is
less than 7” ground clearance, it should be replaced with
a straight draw bar or the unit cannot be properly leveled.
It is important that the TD be operated in a level posi-
tion. Leveling can be accomplished by adjusting the
implement hitch to the tractor draw bar height and lev-
eling the mowerframe by use of the adjustable jack-
stand.
If after properly leveling the mower deck the draw bar
height is less than 8”, a standard pull pin may be too
long. To prevent turf damage in uneven terrain, the
standard pin should be replaced with a 1 x 5” Grade 5
bolt with locknut securely tightened.
