Hi guys and gals I am new to this forum. I just turned 70 and can no longer walk a 1/2 mile to my duck blind. So I bought a basket case tote goat no motor but everything else seems to be there. It seems to be atleast 30 years old. My question is what is the expandable pully on the fist jackshaft. I dont think it is a tourque converter it looks more like a belt tenisor. The guy I bought it from said it had a cenitriful pully clutch. If it is a belt tenser how do I set up the belt pull the pully apart and as the belt wears it will take up the slack or do I have a tourque converter. Sorry about my spelling but I spent most of my younger days in the duck blind instead of school. Thanks
