How do you check gear lube on yard maching tiller?

To check the gear lube on a yard machine tiller, first ensure the tiller is on a level surface and turned off. Locate the gear lube fill plug, usually on the side of the gear case, and remove it using the appropriate tool. Inspect the lube level; it should be just below the fill hole. If needed, add the recommended gear lube until it reaches the proper level, then securely replace the fill plug.
