I put the snowblower on my uncles Toro/Wheelhorse this afternoon. After about 10 minutes the snowblower would not lift up. It was working just fine until then. Everything appears to be loose/free, I can lift the blower with a 2x4 under it. It is almost as if the hydraulic lift of the tractor does not have enough power to raise it. I disconnected the lift arm that connects the blower to the tractor and the lift bar moved just fine. I checked the hydraulic oil and it is right where it needs to be and looks clean. It is 18 degrees, the warmest it has been in a while, negative numbers at night.
Coincidentally a guy I work with is having the exact same problem with his JD. I have no way of warming up the machine to see if it is temperature related. Temperature has never been an issue in the past. Any suggestions?
