Think I narrowed down the loader to 1 of 3 Davis loaders...a 99, 101 or 102. I've come across a online manual where the pics look similar to mine and they came with a option of 1 or or 2 pistons for the front bucket.
I've been following this thread from the start and just remembered there is a listing on agcopartsbooks.com for a 99 davis loader. It lists arms and frames for several tractor models including the MF35. Search "Davis Loader" Massey Ferguson and it will come up with a listing for the 99 loader
Actually that was done with a miller 211 welder with solid wire and a gas mix of argon and co2. Like I said stil getti g used to the welder. Back in feb I welded in some stainless steel bungs into my broncos new bassani exhaust system, welds were perfect. Was surprised how good I did them.You might look around for a better grade of wire. Sometimes the flux wired sold with units are crap. It happened to me on my cheap HF welder. i went to a high grade wire. Same name as one of those high grade welders. Not near as much splatter.
