HW Part Store carries seal kits for John Deere 440C skidder hydraulic cylinder maintenance, covering the boom cylinder, blade lift cylinder, grapple cylinder, and steering cylinder; all replacement parts, not the machine itself.

Exact-fitting John Deere 440C Skidder Parts for Cylinder Repairs
For a full rebuild, HW Part Store offers complete seal kits covering the entire cylinder assembly. The boom cylinder full seal kit fits cylinder numbers AT42696 and AR89437 across all serial numbers, with a 2-inch rod, 4-inch bore, and 2-piece piston configuration.
These aftermarket kits are built to fit the same cylinder assemblies as the original hardware, and stocking one before a cylinder fails can reduce unplanned downtime.
Rod seal kits and bore seal kits are also available separately to support compatibility with specific cylinder configurations. Rod kits include the seals located inside the gland, while bore kits cover the piston seals and outside of the gland.
If you're unsure which kit fits your machine, check the cylinder number stamped on the unit, then find the matching kit among these products.
