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.
