Used 2014 CASE 590 Super N EROPS 4x4 extendahoe with wet kit Backhoe Loader in Perris, CA

2014 Case 590SN EROPS, a/c, heat, 4x4, extend-a-hoe, wet kit, pin grabber, gp bucket, runs and works good, lift cylinder bypasses but does not leak and still works good but has no down pressure, my mechanic says it could be the float function on the valve, otherwise, works very well.
