Took me a moment to see the tach but you got some goodies there for sure as Raymond pointed out. Rear chains are a plus too as they can be expensive to purchase. Getting the L-54A, 60 " Belly Mower, 2 Wheel Dump Trailer, FH Carryall, FH Rear Scraper Blade and weights all around with it is a real plus. And yes, it is quite clear that you have the Touch Control/hydraulics. I have a feeling you got a very good deal.
