Hey guys, I want to get a peerless 700 transmission for my monster mower build. But as I look online, I see some with output sprockets, and some without. I also see some with spined output shafts. I guess you can get spined sprockets for them, right? and are there different model designs that I should be aware of? I want to have a pulley on the input shaft, and a sprocket on the output shaft. I want to use it to run my rear axle.
