Operator Platform Suspension Adjustment; Parking Brake Adjustment - Ferris SRS Z2 Series Operator's Manual

4. Loosen the hardware that secures the PTO clutch anchor
(C) to the engine deck and rotate the PTO clutch anchor
away from the slot in the PTO clutch.
5. Loosen the jam nut (D) on the spring anchor eye bolt (E).
6. Loosen the adjustment nut (F) on the spring anchor eye
bolt to release the majority of the belt tension.
WARNING
Use extreme caution when rotating the idler arm with the
breaker bar, due to the increased tension in the spring
as the idler arm is being rotated. Injury may result if the
breaker bar is prematurely released while the spring is
under tension.
7. Using a 1/2" breaker bar, place the square end in the
opening in the idler arm (G) and rotate the idler arm
clockwise, which will relieve the tension on the belt
exerted from the idler arm.
8. Slide the drive belt (H) over the edge of the stationary
idler pulley (I). Carefully release the tension on the
breaker bar.
9. Remove the old belt and replace with a new one. Make
sure that the V-side of the belt runs in the grooves of the
transmission pulleys (J), PTO clutch pulley (B), and the
adjustable idler pulley (K).
10. Carefully rotate the breaker bar clockwise and install the
belt on the stationary idler pulley making sure that the
back side of the belt contacts the face of stationary idler
pulley.
11. Carefully release the tension on the breaker bar.
12. Reposition the PTO clutch anchor into the slot of the PTO
clutch and tighten it's hardware to secure it in place.
13. Turn the adjustment nut until the coil-to-coil measurement
(L) of the spring (M) equals 3-1/4" (8,3 cm).
14. Tighten the jam nut.
15. Reconnect the wire harness to the PTO clutch.
16. Re-install the mower deck drive belt. See Mower Deck
Drive Belt for re-installation instructions.
Operator Platform Suspension
Adjustment
The lower mounting position of the shock assembly linkage
(A, Figure 59) that connects to the operator platform (B)
can be positioned into one of the five available positions
to customize the ride according to the operator's weight
and/or operating conditions. The lower mounting position
closest to the engine (labelled # 1, Figure 59) is for light-
weight operators, which will provide a softer, more cushioned
ride. As the shock assembly linkage is moved towards the
furthest lower mounting position away from the engine deck
(labelled # 5) the machine can accommodate heavier-weight
operators, and provide a stiffer more rigid ride.
59
To Adjust the Lower Mounting Position:
1. Park the machine on a flat, level surface. Disengage the
PTO, engage the parking brake, turn the ignition switch to
OFF, and remove the ignition key.
2. Remove the clevis pin (C, Figure 59) and hair pin (D) that
secure the shock assembly linkage (A) to the operator
platform (B).
3. Pivot the shock assembly linkage to the next higher
numbered hole (see Figure 59) and secure to the
operator platform using the clevis pin and hair pin.
4. Continue to reposition the shock assembly linkage to
the next higher numbered hole until the desired ride is
achieved.

Parking Brake Adjustment

1. Park the machine on a flat, level surface such as a
concrete floor. Disengage the PTO, engage the parking
brake, turn the ignition to OFF, and remove the ignition
key.
2. Locate the two parking brake springs (A, Figure 60)
above the engine deck on either side of the fuel tank at
the rear of the machine.
