Hi
I have a John deere 3420 loader with hydraulics problems with the steering
the steering is very stiff until another service is operated
yes it is a load sensing fault , the steering isn't getting the system to the pump
Orbital unit changed
Proirty valve checked and the load check valves

the only odd thing is the brakes (which i think may be leaking through the brake pedal
but no one i have spoke to has ever had this fault that i know of

any comments would be appreciated as no one seems to know
