I was given a 100 and I have all the parts except the PTO engagement mechanism. It looks like there is some kind of bar that comes from the front that lifts the clutch with a rod from the lever on the side. Does anyone have pictures and dimensions? I have other mowers that want to give up their parts to make the 100 live. I was told that it had a new short block and I have the side panels, mower. I started at the front and am working my way back rust busting and painting. I think it is going to be my backup mower and grand kid driver. Thanks for any help
