The LH6 error code on your Cub Cadet lawn tractor indicates a problem with the left-hand hydraulic lift circuit. This circuit is responsible for raising and lowering the left-hand side of the mower deck.
Possible Causes:
* Low hydraulic fluid level
* Faulty hydraulic pump
* Faulty hydraulic valve
* Faulty wiring or electrical connection
Troubleshooting Steps:
1. Check the hydraulic fluid level. The hydraulic fluid reservoir is located on the right-hand side of the tractor, near the rear axle. The fluid level should be between the "Full" and "Add" marks on the dipstick. If the fluid level is low, add hydraulic fluid of the type specified in the owner's manual.
2. Test the hydraulic pump. To test the hydraulic pump, disconnect the hydraulic hose from the left-hand hydraulic lift cylinder. Start the tractor and operate the lift lever. If hydraulic fluid flows out of the hose, the pump is working properly. If no fluid flows out of the hose, the pump is faulty and will need to be replaced.
3. Test the hydraulic valve. To test the hydraulic valve, remove the hydraulic hose from the left-hand hydraulic lift cylinder and connect it to a pressure gauge. Start the tractor and operate the lift lever. The pressure gauge should read between 1,500 and 2,000 PSI. If the pressure is too low, the valve is faulty and will need to be replaced.
4. Check the wiring and electrical connections. Inspect the wiring and electrical connections for any damage or corrosion. If you find any damaged or corroded wires or connections, repair or replace them as necessary.
If you are unable to resolve the LH6 error code on your own, you should take your Cub Cadet lawn tractor to a qualified service technician for further diagnosis and repair.
