Bush Hog TD-1100 manual Section Preparation for USE, Attaching to Tractor

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.

2-1 ATTACHING TO TRACTOR

IMPORTANT

(540 RPM only)

The minimum required PTO horsepower is 30 HP for the TD-1100.

WARNING

NEVER STAND BETWEEN TRACTOR AND MOWER WHILE TRACTOR IS BEING BACKED TO HITCH.

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)

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.

Figure 2-1 Tractor Drawbar Adjustment

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.

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

12-1/2” - 17”

Above 17”

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.

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.

WARNING

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.
