Inherited a 1998 TC-102 (Castelgarden) ride-on, which I'm renovating. The main drive belt needs replacing, and the belt guides are welded in place - meaning you have to slacken or remove the pulleys to get the belt on or off. I've got the engine and idler pulley off, but the rear pulley (below gearbox, no access from above) won't budge. As you can see, it has a threaded shaft, and I cannot figure if it's brute force (or a puller), or if it should be unscrewing? Any ideas? I've tried various prying and hammering techniques but no movement at all and it's in fairly good shape as you can see. Definitely no-way of getting the new belt on without getting this pulley below the guides (see photo).
