I removed the blade and clutch pack to replace the main drive belt. The rest of the drive system was easy , i just had to remove one wheel to get to the rest of the system. The replacement parts are good quality. Hopefully they well last 43 years like the originals I replaced on my 1974 Snapper 21 with Wisconsin Robins engine
