Bought a new attachment. EZ Digger back hoe attachment. Hooked it up to the auxiliary hydraulic lines. Works great but when using the thumb wheel to activate the bucket or the swing it makes a high pitched screech noise in the hydraulic line that goes from the coupler on my skid steer along the arm of my lift. It is the only attachment that makes that sound. When the bucket or swing make the full motion and stops the sound doubles??
Probably just the steel aux. line vibrating against the boom arm somewhere. I've had a few machines make that racket when using the bucket curl at a certain rpm.
Thanks, will check that out.
