Proper RPM for PTO operation

[imalumberjack]

Hydraulic heat is bad, can you check temp? There are a couple ways you can deal with this. Re gear pto? on the older models it was just swapping two gears.
Remember its cold out now so consider replacing hydraulic oil with a lighter weight, maybe 32? Tractor hydraulic is multi viscosity. Also look at your setup .... follow the hydraulic lines from the pump all the way through the circuit looking for small fittings (sometimes people repair with what they have and might hinder flow) excessive amount of 90 degree fittings. there is probably not much you can do on the unloading side.
If this is what your primary work will be? I would regear pto to allow truck to run at higher rpm keeping pump at same.
