A PTO dynamometer test will simulate your tractor being under a heavy load. This allows us to find problems before they happen, and replicate problems that only happen under load. This is a great service for commercial as well as hobby operators, to reduce     or eliminate your downtime. Think of it like a health checkup on your tractor.
Special Price, only $250 for complete test. Includes a full printed report on the health of your tractor.
