Before opening the hydraulic system, operate all the hydraulic
controls to release system pressure and avoid injury from the
pressurized hydraulic fluid; refer to
Hydraulic System (page
1. Park the machine on a level surface, lower the cutting deck, shut off the
engine, set the parking brake, and remove the key from the key switch.
2. Raise and support the operator seat to get access to the deck lift manifold
assembly.
Ensure that the cutting deck is fully lowered and supported before
loosening the hydraulic lines, cartridge valves, or plugs from the
deck lift manifold assembly.
If the deck is raised as the deck lift manifold components are
loosened, the deck may drop unexpectedly.
3. Ensure that the cutting deck is supported by the HOC pin and not by the lift
cylinder so that the deck will remain in position during the deck lift manifold
removal. If necessary, support the deck with solid blocks to prevent it from
moving.
4. Clean the hydraulic hose and tube ends and fittings on the deck lift manifold
assembly to prevent hydraulic system contamination.
5. For assembly purposes, label all the hydraulic and electrical connections.
6. Disconnect the hydraulic lines connected to the hydraulic fittings on the deck
lift manifold. Allow the lines to drain into a suitable container.
7. Install clean caps or plugs on the disconnected lines and fittings to prevent
contamination.
8. Disconnect the wire harness connectors from the solenoid coils on the deck
lift manifold.
9. Support the deck lift manifold to prevent it from falling.
10. Remove the 2 screws (item 9 in
that secure the deck lift manifold to the bracket, and remove the deck lift
manifold from the machine.
11. If the hydraulic fittings are to be removed from the deck lift manifold, mark the
fitting orientation for assembly purposes. Remove the fittings from the deck
lift manifold as necessary and discard the O-rings from the fittings.
1. If the hydraulic fittings were removed from the deck lift manifold, lubricate
new O-rings with clean hydraulic fluid, position the O-rings to the fittings, and
install the fittings into the manifold ports; refer to
Fittings (SAE Straight Thread O-Ring Fitting into the Component Port) (page
4–9).
2. Position the deck lift manifold to the machine and secure the deck lift manifold
with the 2 screws (item 9 in
