Zetor 7711 Hydraulic Problems

[cecilz]

I have owned a Zetor 7711 for 10 years and had hydraulic problems since day one. I've replaced the hydraulic pump,fluid, filter, etc. It will barely lift the front end loader or rotary cutter off the ground. Seems to work better when cold and very bad when fluid is hot. Any ideas?

I would had said the hydraulic pump was bet if the loader wouldn`t lift but if changed it already, you really need to put a pressure gauge on if now and what it reading. because you say it works better cold would suggest the gears in the pump are worn

I was thinking since did you check you flow valve is not in the low position because this would make your hydraulics very slow.
