What to do if my Gravely ZT HD won't drive?

If your Gravely Lawn Mower does not drive, make sure that the transaxles are engaged by their levers. If the levers are engaged, but the unit still doesn't drive, the transaxle drive belt may be faulty, or the transaxles themselves may be faulty, in which case you should contact your Gravely dealer.
