This is a stab in the dark . . . I have a John Deere 575 skid steer (a rebranded NH 455). The hydraulics (boom lift and bucket tilt) are painfully slow - almost none existent. This difficulty started recently. The fluid in the reservoir is milky looking. Where do I start with diagnosing this? Drain the fluid, if so, how? I have not been able to locate a drain on the reservoir. Replace the filter? Any and all help will be greatly appreciated - I've got 16" of heavy, wet snow in my 1/4 mile long driveway.
