Why is the boom, arm, bucket, drive, swing and dozer power too low on my Kubota U35-4?
If the boom, arm, bucket, drive, swing, and dozer power is too low on your Kubota Excavators, it could be due to a low hydraulic oil level, requiring you to add oil. Another possibility is leakages in the hoses and/or joints, which would necessitate replacing the hose or joint.
Why is the pressurizer on my Kubota U35-4 Excavators running at full speed and noisy?
The pressurizer might be running at full speed and noisy due to several reasons: * The filter may be blocked, requiring service. * A door or window might be open; ensure they are securely shut. * The cabin sealing capacity might be inadequate; perform a pressure test and seal any leak points. * The sense pipe could be blocked; ensure it is clear and not bent. * The internal sensor could be damaged, requiring controller replacement.
What to do if my Kubota Excavators displays a low pressure alarm?
If the Kubota Excavators displays a low pressure alarm, it could be due to several reasons: * A door or window is open. Ensure all doors and windows are securely shut. * The cabin sealing capacity is not adequate. Perform a pressure test procedure and rectify the cab sealing. * The pressurizer is not operating. Ensure the correct voltage (12v or 24v) is supplied to the pressurizer motor pin A. * The pressure sense tube is blocked. Unplug it at the monitor and ensure clear flow to the exterior of the cabin. * There is a poor power supply. Check the 20A mains fuse and ensure the correct voltage. * There is a poor earth connection. Check the earth continuity at motor pin B.
What to do if filter blocking quickly in Kubota U35-4 Excavators?

Why is my Kubota U35-4 Excavators overheating and the water temperature is in the red zone?
If your Kubota Excavators is overheating, with the water temperature in the red zone, several factors could be responsible. A damaged cylinder head gasket causing coolant loss requires replacement. Low engine oil level needs to be corrected by filling to the prescribed level. Maladjustment of fuel injection requires readjustment of ignition timing. Finally, the use of poor fuel necessitates switching to the prescribed fuel.
What to do if Kubota U35-4 engine suddenly stops?
If your Kubota Excavators engine suddenly stops, check the fuel level and add fuel if necessary. Also, purge the fuel system.

If your Kubota Excavators is overheating, several issues could be the cause. It could be due to a defective water pump seal, which needs replacement. A worn or torn V-belt should be adjusted or replaced. A defective thermostat also requires replacement. Low coolant level needs to be addressed by filling to the prescribed level. Clogged radiator grill or fins should be cleaned. Coolant contaminated with rust requires replacement and the addition of anti-rust. A defective radiator cap should be replaced. Corroded coolant pipes should be cleaned. Finally, continuous operation under full load requires a reduction in load.
