* Low oil level: If the oil level is too low, the oil pump will not be able to circulate enough oil to the engine. This can cause the engine to overheat and seize up.
* Dirty oil filter: A dirty oil filter can also restrict oil flow to the engine. This can cause the oil light to come on even if the oil level is full.
* Faulty oil pump: If the oil pump is faulty, it will not be able to circulate oil to the engine properly. This can also cause the oil light to come on even if the oil level is full.
If the oil light comes on while you are operating your LX176, you should stop the tractor immediately and check the oil level. If the oil level is low, add oil until it reaches the full mark. If the oil level is full, change the oil filter and recheck the oil level. If the oil light still comes on, you may have a faulty oil pump. In this case, you will need to take your LX176 to a qualified service centre for repair.
