1951 Caterpillar D2

[cjmlarson]

Below is a picture of the D2 that was purchased new by Ed & Grace Grinde of Georgetown, MN for their farming operation. They farmed with this until 1969. It sat idle until 1994, when my wife, Jane & I purchased the tractor from Grace Grinde. It was in fair shape when I purchased it, but did have to remove the engine and repair the clutch, and also had to do some minor work to the pony motor. I will be posting some pictures of it working in the field in the near future once I have had the time to scan some pictures.

It will be fun to look at those other pictures to when you get them in
about how much horse powere would a D2 have?

Clayton,

The Cat looks good. I hope you can bring it to the show to let people see it and maybe do some work with it.

Some Cats had a belt pulley on the back. If you have one on your Cat, we would be happy to run your Cat on a Prony Brake and check out your engine.

A few facts and figures: Four cylinder diesel, 252 cubic inches, 1525 rpm at full load, bore is 4", and stroke is 5". The drawbar hp is 32, and the belt hp is 38. These HP numbers can be disputed, depending on which books you look at. But we do know, that with the playing we have done with it, it will pull alongside 50hp tractors with no problem. This unit has 12 inch trackpads, which is 1308 square inches of ground contact. Unit carries 20 gallons of diesel fuel and weighs approx 7,000 lbs. It has a 5-speed transmission which goes from 1.7 mph up to 5.1 mph. This unit also has a 2 cyl opposed gas pony motor for starting. You can either start the pony motor with a rope on the flywheel or take the lazy man's way and use the electric start.

This is my dad, Jack, riding on the plow adjusting the plow as we go. We were in some quackgrass trying to get this John Deere 4-16 bottom plow to scour. The D2 didn't have any trouble pulling this plow in these conditions.

This is another picture of the D2 in the field, pulling a 10' tandem disk in the spring. It was quite muddy and the disk wanted to plug up. The faster I pulled it, the less it would dig into the mud and not plug up. Again, we were just playing and having fun.
