I have a 753G. I do a lot of mowing with a brush cutter and use the 753 for the tight places that I cant fit a bigger machine into. With that in mind, when I run OTT Tracks, I hate the extra width that the spacers used. I had a job tomorrow that had 64" of clearance to get the machine past a building and to the lot that needed mowing.... no-go with the spacers installed! I got to looking at the tie-down points behind the rear wheel and decided (because I never use them) to torch them off, which would let me run the tracks without spacers. Well........... the &%#^ing fuel tank burns quite well when an oxy-acetylene flame gets to it! Instead of mowing tomorrow, I'll be pulling the engine/pump ass'y. Man, do I feel stupid!
