poor design

[bungybob]

why does the hydraulic pump on my poulin pro z turn mower slow down after a short time operating? once cooled or let set for an hour it works great and slowly starts to slow down?

I am no expert, but it sounds like an over-heating issue. I'm not sure what you have for hydro units, but they should have a cooling fan. I would check to make sure that the blades aren't bent, something blocking air flow, etc.

If you can, you should also check the fluid level to make sure that it isn't too low.

If you can provide the type, model #, etc of the hydro units, the experts here (not me) should be able to help.

Thanks for the reply!
The unit is a hydro gear #ZC-DHBB-3D5A-2DPX.
Will this help with a diagnosis?

I really won't be of much help since I have little to no hydro experience, but hopefully one of the experts will chime in.
