Have no manuals or documentation, purchased tractor last year from individual moving across country. All I can advise it is a 10A fuse that when it blows the only thing that quits working is the PTO. Ran PTO today for over an hour with no load, and fuse held up. Put bush hog on it and mowed for about 15 minutes and it blew again. Tried replacing fuse and they blew immediately. Turned tractor off, let it cool down, replaced fuse with the mower shaft off of PTO and it ran perfect. Put bush hog shaft back on PTO, fuse held up for apprx 3 minutes and starting blowing fuses again. Thank you for reading and offering support.
