How do you change gear lube on mtd snowblower?

To change the gear lube on an MTD snowblower, first, ensure the machine is off and cool. Locate the gear case, remove the fill plug, and drain the old lube by unscrewing the drain plug at the bottom. After draining completely, replace the drain plug, then fill the gear case with new lube until it reaches the proper level, and finally, reinsert the fill plug securely. Always refer to the owner’s manual for specific lube type and capacity.
