Hustler Turf 3500/3700 owner manual Cutting height adjustment

7.If the measured cutting height is significantly different than the 3.5” desired height than the front of the deck will have to be adjusted at the two front gauge wheel forks. The rear of the deck will have to be adjusted by moving the pins up or down in the adjusting holes. Refer to Cutting hieght adjustment section for more detailed information.

NOTE: Minor leveling can be accomplished by moving the 1/2” cap screw on either front gauge arm mount forward in the slot, to raise cut- ting height, or backwards to lower cutting height. Fig. 3-7

8.If one side of the deck is more than .25” higher than the other side, lower the high side of the deck by transferring the .25” gauge wheel spacer from under the gauge wheel fork bearing to the top side. (Fig. 3-8 and 3- 11)

Lower the rear of the deck .25” at the rear height adjustment pin one hole. Fig. 3-9 and 3-13

9.The mower deck should now be level.

Cutting height adjustment

WARNING: Make sure PTO clutch switch is off, engage trac- tor parking brake, stop engine, and remove ignition key before making any adjustments to mower deck.

For best results, make cutting height adjustments on a hard flat surface. The mower deck can be height adjusted in back as well as in front.

The mower deck has two different cutting height range settings: 2” – 6” or 1” – 5”. The deck is preset at the factory to the 2” – 6” setting.

Both front and rear height adjustment are in 1/4” increments.

For a quick check of height adjustments: Measure from level surface to top of mower deck (as indicated in Fig. 3-7) and subtract 5.09 inches. The balance will be blade height. To be sure mower deck is level, measure at front and back on both left and right side of deck. Fig. 3-6

To adjust front cutting height

1.Park the unit on a flat surface, set the park brake and using the tractor’s hydraulic system lift mower deck off the ground. Shut off tractor engine. Place 8” tall blocks at the four corners of the deck. Restart engine and lower the deck onto the blocks. Shut off tractor engine and remove key from the igniton switch.

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

WARNING: The deck must rest on the blocks to prevent the deck from being lowered suddenly by the accidental move- ment of the tractor’s tool bar lift control lever.

2.Pull up and forward on gauge wheel handle and lift or lower wheel to desired height (Fig. 3-10). Both gauge wheels should be adjusted to same height for uniform cutting.

NOTE: To change cutting height range setting to the 1” – 5” range, reposition the two .5” spacers, located below the gauge wheel bearings, to above the bearings. Fig. 3-11 & Fig. 3-12

NOTE: 2” – 6” cutting height range: Recesses on side of gauge arm mounts visually indicate cutting height in 1/2” increments. Each notch between recesses represents a 1/4” adjustment. When the bottom (lowest) recess is just visible over top of gauge wheel assembly, cutting height is set at 6”, when the mower deck is set in the 2” – 6” range (see Fig. 3-7). Next mark up indicates 5-1/2”, then 5” and so forth. Top mark indicates 2”. Move gauge wheel assemblies all the way to top of arms for 2” cutting height.
