To be clear I posted "In the future you might get better responses if you post your MF questions down below in the Massey Harris and Masey Ferguson discussion Forum that is here in the Manufacturers section.", I did not ask you to move it. Here is a link to it so those that missed it there can see it and maybe add info.
Massey Ferguson 35 help
miner09 posted the multipower lever is missing. It belongs in the open slot, pictures below. Your description of it not rolling backwards when the clutch is pushed going uphill is something high Multipower does, the straight gear transmissions will not do that.
Did you go to the links I gave you and download the manuals I found? I agree they don't give great detail in the service manual, so you have to use the manuals with the parts book. The page I clipped out below is from the Operator's manual and shows the Multipower lever. The drawing in the parts book shows the pieces to look for. My hope is someone here that follows this forum might have missed your thread on the Tractor& Farm Talk forum and will be able to provide you some actual pictures of their 35 Multipower linkage. I would but I don't have a 35 to take pictures of. I am still looking for better pictures showing the linkage.
Take a couple pictures looking straight from the sides into the area under the sheet metal down to just below the top of the transmission case, from the rear of the steering box to the back of the engine. We may be able to spot and point out some of the linkage of the multipower to help you.
