I have a friend who has a M670 diesel his Dad bought new. Myself and a buddy are going to help him get it back together after someone stalled out on a restoration attempt. We are not MM guys, just trying to help out a neighbor. Will probably be asking more questions as we go. Does this tractor have a wet clutch? Where did the factory mount the battery? What color combo does this year tractor usually have? This has dual PTO, how common is that? Thanks for your answers in advance. Pat

The main clutch isn't a wet clutch. The ampli-torque (long lever on the right side in front of the brake pedals) does run in oil. It is a 2 speed "power shift" similar to the torque-amplifiers on IH's. If the tractor is a gasoline or LP model the battery is mounted on the inside of the right rear fender, on top of the axle. You more than likely will need a battery tray for it, since it sounds like you are missing it. They use a 3EE or the more common 3ET battery, which is a long skinny one. If it is a diesel model then two batteries are used, one on the inside of each fender. If you can post the serial number for it, which is located on a brass plate on the transmission by the clutch pedal, will help. I believe most of the 1967 models were all energy yellow. The 1966 models had dyna brown on the engine and rear end. I can email you a picture of a 1967 from some literature. Dual pto's weren't all that common on the M670 Supers. This is what the 1966 models look like. On the 1967 models all of the brown was replaced with the energy yellow.

Alan, if you'd care to take the time, could you explain the allure of the 670, particularly vs. it's predecessor, the M5. M5's can be had everyday but 670's bring money for reasons I'm not aware of. Share with me your 2 cents. Oh, and I was going to say about the battery location, unless you're going for "restoration" quality, forget those long skinny batteries and their location. Fabricate a tray and put a conventional battery up closer to the starter, AND, no need for 2 batteries. None of my diesels have 2 batteries, just one good one.

M670 Super is an all around better tractor than the older M5, M602 & even straight M670. MANY improvements, #1 Better Hydraulics,then also more HP, better Shifting mechanism, heavier wide front axle, nicer dash... the list goes on. In my opinion & many other, it also looks much better, I never cared much for the M5. We had an M602, was a great tractor, but hydraulics were less than needed. Not to mention the M670 Super is the last "MM Built" tractor of this size, so that adds collectibility for many people that don't want a Yellow Oliver, or Silver White tractor.
That's pretty much how I feel about the M series Marty, however I do like the combo of the Prairie Gold and bronze on the earlier M5's. Power steering and hydraulics have always been inadequate on the earlier models(my 5 Star included). I also like the removable hood sections on the later tractors...very quick and handy.

Dual pto is kind of a rare option on an M670 super. We recently put one on ours. We have one brown belly (66 model) and a yellow belly (68 model). Very handy little tractors. Ours is used primarily to turn a grain auger, but it also drilled wheat, raked hay, shredded corn stalks, etc.
I have had several customers with factory dual battery system that have been switched to a single. You can do it but its pretty hard on the starter. Lower cranking amps let the solenoid or Benedict arc farther making a welding effect. If your going to use it in the summer to go to the parade it'll work fine. If it starts below 50 degrees or so it gets hard on electrical components but will probably work.
