I've got a 953b that has lost speed over night. Runs faster at mid throttle. Open throttle and slows. Changed hydraulic filters. One in the tank and the one in the canester on top of the hy'stat. Still no speed. Plenty of power. Doesn't slow as I'm lifting the bucket while trolling. Any help would be awesome.
yes most likley loosing pressure to underspeed valve inside hystat. u will need to take pressures to verify.
