How do you change Yard machines by mtd hydrostatic drive fluid?

Answer:
Remove the battery and tray. Remove the vent tube on top of the transmission. Unscrew and remove the plastic vent tube nipple with an 11/16 deep socket. Use a marine gear lube pump to remove the old oil. You can buy this at Walmart for $10 made by quicksilver. Refill with 20w50 motor oil.
