Slide uni- versal joint onto gearbox shaft. Secure PTO shaft to gearbox shaft with 5/16” cap screw, flat washer, and 5/16” nut provided. Fig. 3-2 and 3-3

2.Lower tractor tool bar.

3.Block rear of mower deck up so that the deck carrier arms are at the same height as the tractor tool bar.

4.Drive the tractor ahead slowly and insert mower deck carrier arms into the tractor tool bar. Stop tractor engine, engage park brake and remove key from the igniton switch. Fig. 3-4

WARNING: Stop engine. Make sure PTO switch is off. Engage park brake and remove ignition key before getting off machine.

5.By moving the mower deck, align the holes in deck carrier arms and tractor tool bar.

6.Insert tractor clevis pins through holes in tool bar and carrier arms and lock clevis pins in place using hair pins provided. Fig. 3-4

7.Attach the PTO shaft to the engine shaft. Fig. 3-5

8.The mower deck is now ready for the deck leveling procedure. To remove deck from tractor, reverse above procedure.

Leveling mower deck

NOTE: Levelness of mower deck when lifted from surface does not affect levelness of cut in mowing position. Mower deck will mow (cut) level if it is level when set on level surface.

Refer to tractor owner’s manual for correct tractor tire pressure. To level mower deck use the following procedure:

1.Park the unit on a flat surface and set the park brake. Shut off tractor engine and remove key from the igniton switch.

WARNING: Stop engine. Remove ignition key before getting off machine.

2.Check the deck’s tire pressure and adjust it accordingly. Tire pressure should be 8-12 psi (55-83 KPa).

3.Set the 3500/3700 tractor’s Tool Bar Lift Control Lever in the fully for- ward position. (Refer to tractor’s owner’s manual for complete informa- tion.)

4.Rotate the 3500/3700 tractor’s Weight Control Valve knob counter- clockwise as far as it will turn to achieve the minimum weight transfer setting. (Refer to tractor’s owner’s manual for complete information.)

5.Set the deck cutting height to 3.5” at the two front gauge wheel forks and at the two rear height adjusting linkages.

(Refer to Cutting Height Adjustment section to set cutting height.)

6.Measure from the level surface to the top of the deck. Fig. 3-6

The top of the deck is 5.09” higher than the actual cutting height. Take the measurements at each of the areas shown (Fig. 3-6) and subtract 5.09” from them. That will give the actual cutting height for that loca- tion.

Example: 8.59” (top of deck height)

-5.09” (top of deck to blade distance) 3.50” (cutting height)

NOTE: The rear of the deck should be .2” - .5” higher than the front of the deck.
