LEVELING THE DECK AND SETTING THE COUNTERBALANCE SPRING TENSION

CAUTON

STOP THE ENGINE, SET PARKING BRAKE, REMOVE IGNITION KEY AND SPARK PLUG WIRES FOR SAFETY.

1.Set all tire pressures to the correct specifications.

2.Rest machine on a level slab of concrete.

3.Depress the deck lift pedal to raise the deck to the full lift height position and move the height adjust pin to the 4.5” position.

4.Take all the force off the deck lift spring by loosening the nut at the front of the spring.

5.Place a level on the deck, from front to rear. If the level is too short to reach all the way from front to rear, lay a straight edge on the deck first, then place the level on the straight edge.

6.Lay a .12” spacer beneath the front level. this will automatically set the rear of the deck higher than the front.

7.Adjust the bolts in the slot to raise the rear of the deck (Shown below) until the level’s bubble is cen- tered. Repeat for the other side.

8.Check to verify the deck is leveled side-to-side. To do this, lay a 2” x 4” x 30” piece of wood under each side of the deck and lower the deck to rest freely on the top of these boards. Inspect the (3) lift hangers to see if tension is on each of them. If any of the hangers appear slack, adjust the bolt in the slot to remove the slack.

9.Raise the deck up to the transport position and pin in the desired height position.

10.Remove the 2” x 4”s from under the deck.

11.Tighten the counterbalance spring nuts until spring is to the following length:

Deck Lift Spring

36” & 42” Deck- Spring length of 16” for 3” cut- ting height. For lower cutting heights loosen springs at 1/4” intervals until stop hits adjusting pin in correct height location. If deck floats, loosen springs at 1/4” intervals until deck stops floating.(Measure from back of flatwasher to back of flatwasher)

DECK BELT ADJUSTMENT

Belt adjustment should be checked every (50) hours of operation to get maximum life and cutting perfor- mance. Belt tension is adjusted by increasing or decreasing the length of the spring on the movable idler by adjusting the eye bolt length (Shown below). For correct belt tension, adjust the spring length to 7” for the 36” and 7-1/2” for the 42” deck.

DECK BELT REPLACEMENT

(NOTE: Use only genuine Bush Hog replacement parts)

1.Remove the R.H. and L.H. deck shield assem- blies and remove the foot platform.

2.Relieve the spring tension by loosening the two 3/8” hex nuts on the spring adjustment eye bolt.

3.Remove the old belt.

4.Install the new belt being sure the belt is properly routed and positioned in all sheave grooves.

5.Adjust tension on the belt by adjusting the length of the spring on the idler (See Deck Belt Adjustment section).

6.Replace the deck shield assemblies and foot platform.
