Brake Linkage; Deck Drive Belt Adjustment - HUSTLER Super Mini Z Parts Manual

NOTE: The front brake link is not adjustable. Fig. 11-24
2. Raise and block the tractor up so the drive wheels are off of the
floor.
3. Open the hydraulic pump's bypass valve (Fig. 11-25), on the side
that is being adjusted, by turning bypass valve counter clockwise
one-half to one revolution. The valve stems on each hydraulic pump
are located near the top and are identified as a hex stud.
4. Rotate the tire. The tire should rotate. Remember hydraulic oil
resistance will prevent the tire from rotating freely even with the
bypass valves open. There should be no resistance from the brakes
at this point.
5. Move the control lever to where it is just inside (1/8") the park brake
slot. Fig. 11-26
NOTE: When the control lever is against the outside edge of the the
slot, the brakes should not be engaged. Fig. 11-27
6. Rotate the tire. If the brake is adjusted properly the tire will still
rotate but friction will start to become noticeable here. However, if
no brake resistance is noticed, the brake needs adjusted as follows:
7. Loosen the brake linkage jam nuts. Fig. 11-28
8. Rotate the tire and at the same time rotate the turnbuckle to shorten
the length of the brake linkage to increase the brake pressure. When
you feel the brake begin to engage, stop adjusting the turnbuckle.
Re-tighten the jam nuts on the turnbuckle.
9. Place the control lever in the park brake slot (Fig. 11-29). The tire
should not rotate when the control lever is in the park brake position.
10. Place the control lever in the neutral position. The tire should rotate
freely.
11. Close the hydraulic pump's bypass valve.
12. Repeat steps 3 thru 11 for the other side.
13. Remove the jack stands and lower the unit. It is now ready to
operate.

WARNING: If the pump belt fails, loss of control will occur
especially when operating on a slope. If you lose steering
control while operating the machine, place the steering
control levers in the park brake position immediately.
Inspect the machine and involve your Hustler dealer to
resolve the problem before continuing to operate.
