Our take on the John Deere 8640-8650 4WD Series Tractor Replacement Seat & Air Suspension - Fits Various Models - Brown Cloth

A complete replacement seat and air suspension kit for John Deere 8640 and 8650 4WD tractors. It pairs a Grammer seat top in brown cloth with the compact Grammer MSG93 air suspension, a self-contained 12-volt compressor, a pedestal, slide rails, an adapter plate and install hardware. The reclining backrest, tapered back support and fold-up armrests make it a more adjustable setup than a worn fixed seat, and the narrow suspension frame suits tight cabs. It is aimed at owners restoring or upgrading an aging factory seat rather than at buyers wanting a basic static seat.
