I'm enjoying watching some of these past clips because each time I do I get reminded of things from the past. Much like how this tractor is going to be a drawbar machine instead of a dozer. That's pretty neat, and as I said, reminds me of an old d4 a friend had and caged up with an added on bench to the back to carry two or three people if you didn't mind being very cozy. As well as some deer stands or a few deer or hogs. He'd use it as a woods cart and just drive it through the under brush and briars, knock over small trees and scrub palms. Wade it through a creek or wet areas to collect hunters and whatnot. It had a full home built dage and large bull bar on the front, a pto winch off the back with a few snatch blocks to redirect the cable forward if needed. As I said, a bench on the back for extra seating, a short mesh footboard for cargo, snorkel and extra lighting. He loved that crawler and kept it in fantastic mechanical shape, looks though were another story. I just st got to thinking about it when you said that this one would not be a dozer.

Fascinating stuff and things most people would never think about. Clearly track and undercarriage wear is the weakest area with these machines but then track systems are complicated with lots of moving parts. For a hobby machine seeing a few hours a year I would be reluctant to spend loads of money and overdo the restoration to get everything back to factory fresh. Here in the UK engine work and general engineering work is quite expensive and its not easy to find people prepared to do the work. On one of my stationary engines the crank pin was 20thou out of round. I couldn't find anyone prepared to grind it so I sat with a file and micrometer and re-filed the pin round. It sounds horrendous but the engine runs well and has done for over 10 seasons now. Its not under much load though.

Thanks for the Video excellent content . I have owned and operated bulldozers over many years and while i already had an understanding of how track design worked ive never heard it explained so well . I believe Caterpillar say theres 5 times more wear on the pins and bushings in reverse than in forward . I worked for a contractor that had done his time on D2s and D4s and was very strict on keeping tracks clean and adjusted correctly plus good driving habits like not backing over dirt spill from blade and driving forward when travelling from site to site . Because he was bought up on dry back end he was very strict about not using the brakes . When he had D6s and D 7s and we would paint them up in the off season he would say he wanted to see the paint wear off the floor boards before the brake pedals . It was good advice and a good habit to form . Thanks again enjoyed your video

It will last a lot of years the amount of hours you put on it if you were going to plow a 1000 acres a year with it then it is a totally different scenario.

Hey, Squatch, I know you like those odd-ball stories, this one might interest you 🙂 Guy I used to work with was Ex military (REME - Royal Electrical and Mechanical Engineers) if memory serves. He had been on winter exercises in Europe with a NATO Tank force, with units from the US, UK, Germany Etc. One really slippery hill stopped them all. No body got more than half way up. There was a really smug know-it-all in his unit that nobody liked. This guy said: Reverse the tracks, and they will go up, no problem. It did not get a good reception. BUT. Eventually, they gave it a try on one of the tanks. And. . . . Up she went. NO problem. Once all the UK tanks got to the top, Then they let out the secret. Your explanation at 07:00 would explain why that worked. I always wondered exactly how that worked.

Hi Toby, informative video. A point you did not address in this video, and probably was not in the remit, was the ‘Sprockets in front versus Sprockets at the rear’ argument and how that relates to track ‘power’ and wear. I operate a 32t Excavator set up as a ‘Shovel Logger’. Driving up a hill ‘backwards’ draws noticeably more power than going ‘forwards’. The machine really struggles to move in reverse uphill. Tank design in WW2 explored this argument with some manufacturers going for rear sprockets, while others went for sprockets at the front. Although Tanks are a different thing to tracked tractors, the results of the argument were not conclusive.

This is a completly new look at how a track works (or this era track?) I can see he aspect of it as a drawbar unit (aka Farm Field work mostly though grader or dump pull) but as a dozer, you are pretty much even with forward and reverse (as well as a loader). It would seem that for that intent a compromise track would work better (no idea if there is such a thing). Overall there would be more forward than reverse but it would be a lot closer to a 60/40 split at a guess. I worked around a JD350B as well as operated it some, we tended to dozer and loader work (Drott 4 in 1 bucket) so that would have had a 55/45 split at a guess. Still a bias forward as we had a backhoe setup on it and that was mostly forward with a bit of backing up.
