Bucket Cylinder is the part that curls and tips the bucket. We send oil into one side, and the piston moves to tilt the bucket down or up. It lets us scoop, dump and grade material easily. We mount it close to the bucket link so the force goes straight. When it leaks, our bucket control gets sloppy, so we replace seals and keep the oil clean. It is simple but vital. No cylinder means no bucket, and we can’t dig much.
