Testing the Lift Circuit–Lift Cylinder Internal Leakage
Groundsmaster ® 4300-D
16226SL Rev C
Perform a lift cylinder internal leakage test if you identify a cutting deck raise and
lower problem. This test determines if the lift cylinder being tested is damaged.
The lift cylinders must be tested individually.
Note: The raise/lower circuit operation can be affected by the lift cylinder
binding, extra weight on the cutting deck, and/or binding of the lift components.
Ensure that these items are checked before continuing with the lift cylinder
internal leakage test.
