Ransomes Turf Track


Wonder if anyone can help me, I brought a ransomes turf track ride on mower with a hydrostatic drive, was working great then the drive started playing up, then stopped all together, and now the hydraulic lift for the mower deck and articulation has stopped working too.

I have changed the filters and put fresh oil in, i have searched the internet to try and answer this problem but with now joy :(

Could it be the pumps that have packed in or something else? Can anyone suggest anything?

So, the engine runs but no hydraulics work, could this be something as simple as the connection between the engine and hydrostat unit has failed ?

Otherwise, we are going to have to start a masterclass on fully variable, fully reversible axial piston pumps. If you do need to start testing the hydrostat unit, you are going to need a collection of pressure gauge's.

Could not find info on website of Ransomes/Jacobson. As far as I know this machine was made by Steiner Inc USA and sold as Ransomes. Suppose it has a Sundstrand 15 series hydraulic drive. Always first check if by-pass valve is close . and of course if engine drives pump as suggested by hortimech.

After that you end up with inspecting various check and pr. valves and measuring pressures in the system.
