The control manifolds for the three cutting deck sections are very similar.
Note: When servicing the control manifolds, DO NOT interchange parts from
one control manifold to another.
Note: The ports on the cutting deck control manifolds are marked for easy
identification of components. Example: PRV is the proportional relief valve and
M2 is the return flow from the deck motor. See
to identify the function of the hydraulic lines and cartridge valves at each port.
1. Read the General Precautions for Removing and Installing Hydraulic System
Components (page
2. To prevent contamination of hydraulic system during manifold removal,
thoroughly clean exterior of manifold and fittings.
3. Disconnect wire harness connector from the proportional relief valve solenoid.
4. Disconnect hydraulic lines from manifold and put caps or plugs on open
hydraulic lines and fittings. Label disconnected hydraulic lines for proper
assembly.
5. Support the cutting deck control manifold to prevent it from falling.
6. Remove two (2) cap screws, flat washers and flange nuts that secure
manifold to frame and remove the control manifold from the frame.
