Hour meters are a great accessory to add so you can keep track of how many hours you have on your tractor. Why do this? The main reason is so you can perform maintenance at the proper intervals. Doing so will keep your tractor running in optimal condition AND save you money in the long term. Prices range from $34.99 on most gas engines to 99$ for diesel engines (installation included when purchasing with tractor).
NOTE: GAS ENGINES HAVE HOUR AND TACHOMETER. DIESELS ARE HOUR METER ONLY.
