Hi, I am new to the site and desperately need instructions on how to replace the drive belt for the 42 Stander. This machine cost me close to 7k and I can't get a repair manual for it. There is something profoundly wrong with that. The local repair shop is a total ripoff. I do all my own repairs and since buying redmax weedwackers and blowers a few years ago--that is not a big deal until now. This machine weighs a whole lot and trying to view the repair area is a colossal task. A quick look has me guessing I have to remove a pulley and what looks like an electric clutch? not sure how to do it shade tree style. I really appreciate this site and any info would be greatly appreciated.
