Hello Nev, As mentioned in the past but too far back to find many of us up this way with 2 and 3/4 have fitted C section 78 inch endless belts. They can be fitted by removing the rear stay and stand and not using a joining link. It would be necessary to fit a 1/2 link in the primary chain to get the gearbox in the right position. The belt will be a little tight at first but will stretch and for one thing no broken joining link and no slip. Cost would be around $30 and available agricultural and machinery outlets???????? Alan
