Gear Case

To keep our drive system working properly, the gear case and area around the drive should be kept clean and free of trash build-up. Clean under the drive cover twice a season.

The gear case is filled with lubricant to the proper level at the factory. The only time the lubricant needs attention is if the service has been performed on the gear case.
