I replaced my L4200 seat long ago just because I wanted a more adjustable one with armrests. I found a deluxe Kubota seat on Ebay, My tractor has a cab so the seat never gets any weather or dirt...
You can replace yours with about any that you find at your local tractor store, TSC, Atwoods, Orschalunds... They all have different seats. You can adapt to your L4200 easily using a square piece of 1/8 inch thick steel. Just remove the front hinge piece from your old seat, mount it on the steel plate, mount the steel plate to the new seat. Remount the hinge to your tractor.. KennyV.
