Bucket Hydraulic Cylinder to Suit Kubota U55-4, KX057-4 Mini Excavator

Restore crisp bucket response on the Kubota U55-4, KX057-4 with this direct-replacement bucket hydraulic cylinder. It arrives fully assembled with barrel, rod, piston, gland and seals, manufactured to OEM dimensions so it bolts straight in. Cross-references OEM part number RD551-67803 / RD551-67804.

If the bucket drifts open while carrying a load, struggles to curl in hard ground, or the rod is nicked and leaking, the cylinder has had its day. A complete replacement avoids the wait for a workshop rebuild and gets you back on the job sooner. This size of machine is a favourite for house-site preparation, services trenching and farm work — and that constant cycling takes its toll on cylinder seals and rods.
