I'd guess it's a straight with C stickers.

Yeah that's no 350 C. I agree with 77Ford. I think it is a straight 350 with someones homemade decals calling it a 350C.

I don't see a problem. He's shifting from forward to reverse using the transmission instead of the reverser lever. Just like I do on my 350C.

A 350C series does not have a reverse to the best of my knowledge. It was eliminated once the reverser became standard.

I have a 1980 350C and when I ordered it from John Deere I got the 3 point rear lift option. Deere's engineers knew that by using the reverser to go in reverse the PTO shaft would spin in the wrong direction. I use a Farmi winch and put a lockout on the reverser lever so I don't birdcage my winch.

350C Operator's manual, OMT79469, has a note that only crawlers equipped with a PTO or winch had reverse in the gearbox. The spec sheets on the JD Construction Non-Current Models Website show the 350B and C as 4 forward and 4 reverse speeds. So it may have been an option with a winch or PTO on a C.

Definitely appears to have a winch drive on it. I spoke to the owner and he said he had the floor plate off and there is a reverser on it. The serial number is 269762.

I have to admit, now I believe it is a 350C. I did not see the reverser lever the first couple of times I watched this video. So then I thought it could be a 350B since it had the lever there on the battery box. I see the guy shifting the transmission into reverse and also how far he is pulling the levers to steer the machine and I thought it was an old straight 350 without a reverser.

I was convinced that you were all wrong so I went back and watched the video again while pausing it several times to see if I could pick out anything that would confirm one way or another. After watching, pausing and backing up the video several times I now see that it is a 350C.

The video quality doesn't help in that it is slightly blurry and it was hard to pick out certain details like the brake anchor bolts on the face of the final drives. Finally after spotting a couple of frames of video where those anchor bolts are visible I determined it is indeed a 350C.

A straight 350 through the 350Bs do not have these brake anchor bolts and also the final drive housings are a bit different. Also the question on the 350Cs having a reverse gear in them depended on whether it had a winch drive or PTO installed or not. You could actually order them without PTO and still get reverse gear in the transmission.

On a side note... Where I worked the powers that were at the time thought that with this reverse gear feature you could still back the machine up if the reverser quit working. Which is ridiculous since the transmission is behind the reverser. If the reverser quits then you don't have power going through to the transmission.

There's a few other quick ways to identify a C machine from a B or straight besides the anchor bolts.

The track frame support for the rear crossbar is fabricated versus cast, and runs parallel vertically with the track frame.

Later C dozers used a shortened track frame similar to the loader, and have no sprocket shields.

The C had a tachometer with green and red color behind the RPM indication

If it's a 6305 6-way dozer, the tilt cylinder guard runs at a steeper angle, to the point that the upper cylinder mount doesn't protrude above it much. The slides for tilt also switched from being weld on to bolt on in the C run.

Granted, on machines that are 40+ years old, components may be mixed and matched at this point.

As Leonard said, reverse gear in the transmission was still available in the C for the winch drive, it just wasn't needed any more as the all had reversers, whose pump supplies pressure to the steering clutches.

To make it even more confounding, just because it has a winch drive or PTO option, doesn't mean it was ever used. The first 350-C I ran as a kid had a PTO option with the little lever on top of the transmission, similar to the M-430 Dubuque's, and it was a loader with nothing out back....go figure!
