Q: I have a Luzhong 454 and the rear lifter is not working.
A: There is switch located in the front of seat posiiton, it is for the control of hydraulic remotes and the lifter, counterclockwisely turn it to end, the oil flow of the lifter will close. If problem is not here, the lifter distributor valve should be jammed by dirty oil.
Q: Do you have an oil type you recommend or would the Nulon ISO 68 hydraulic fluid be ok?
A: Engine oil sump use SAE10W (below -5 degree Celsius) and SAE15W/40(above -5 degree Celsius)

Brake system use SAE10W.
Q: My Luzhong 554 tractor cannot start...
A: Firstly check starter motor fuse-wire, then check cluch switch and starter relay, at last check ignition lock…
Normally problem is fuse-wire of the starter motor break off. This fuse-wire is in front of starter motor (not in the fuse-box).
Checking the clutch switch if it is failed, one way is connecting the wires behind the switch, if the engine can start by key, that mean clutch switch is failed...If it still cannot start by key through above method, then keep clutch switch to original and check fuse-wire...
Even if all above parts failed, we use key or screw driver to connect the 2 polars in front of starter motor, it can make engine start.
By the way, Luzhong 25 series tractor has no this fuse-wire.

Q: Why my tractor clutch is not good as the beginning when we use for some time? On the other words, why clutch treadling range becomes longer?
