Toro 52" Grandstand
I recently bought (3) 52" Grandstands. Love the machines!! We are having a problem with one of the units. After about 1.5 hours of use the control levers become very difficult to push. We are using Mobil 1 oil. The machine has 150 hours of use on it. The temperature coming off of the pumps are right side 162 and left side 184. Please advise.
