Anyone know what some of the years lp tractors were around? I know JD had some. Today I was at the toro dealer and we saw a lp z mower, I worked at a dealer that had a lp forklift, now I see a lp mower. Guy said it would run 10 hours intermittently, mow a lawn go to next job ect. He said $25 to fill the tank, which is bigger than gas grill tank that costs $20. ????? Anyway he claimed its the first one the got in, and the wave of the future, asked if I wanted to buy it, I said nope, 2 things I will never buy again, 1st a kohler engine on a mower and second a toro! I'd get a diesel on a exmark. But the whole thing got me thinking about pic I've seen of tractors with the lp tank on them! Lol
