There should be manuals for this machine here.I uploaded a dozen or so manuals that I got off of the Gilson Yahoo Group.
Ya they are still here.
I can't find the older one for the 15hp varidrive manual transaxle but one of the slightly newer ones use the same parts.The only difference is the fenders and the shape of the hood.
Here this one covers both the 4 speed Varidrive and the hydro.
Attachments for these older Gilson/Wards tractors are a bit hard to find.If you can find a deck for it in Any condition I would grab it up even if the deck shell is completely rotted out.You can always weld it up or have some one do it for you cheaper than buying a whole other tractor.
I wish I would of kept my old gilsons.I had 2 16hp hydros 1 15hp varidrive 1 18hp twin hydro and about a dozen of the lighter built 5 speed MTD made gilson GTs with the 12" rear tires.
