Hello pete, What I would like to know is what they changed to make them run 17mph. My TR 96 tops out at 14.7mph. I haven't heard of any way to increase ground speed other than larger diameter tires. Rod
I am sorry I can not help tou with your question. If you put a smaller pulley on the hydrostat pump it should pump more oil to the motor therefore giving you increased speed. I am going to run that by the service manager.
