Hydro shudder/chatter
Just changed out the whole rear end and hydro pump on my 1250. The reason for the change was my hydro pump was leaking from the hydro pump housing itself where the 2 halves go together. Thought it would be easier to change out the whole business. Don't have any experience since it came from my 1450 parts tractor that I have driven very little.
Everything went well in the change and even put on a new cub filter, new trunion springs and lubed up the hydro plates for hopefully a smooth drive. This one seems very strong in the drive department, it's not a lazy hydro pump. Used it today for the first time to mow an acre and a half and it seems to shudder or chatter a little bit going up the slight grade in the yard. Does go away if I change to a faster speed. Seems like it my be slipping a little. I find it hard to believe as robust as it seems to be. Noticed it more when it got warmed up. The hydro fluid I did not change, just topped off with generic brand fluid. The color of the fluid was kind of yellow/green not clear. What do I do to remedy this? Change the fluid? Switch over my valves? Or change to another pump?
