D-21's "horded" common damage?

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I wasn't really sure how to title this. Basically, a guy that has the family farmstead, collects farm related "stuff". Tractors, balers, power wagons, spreader, etc, etc, ETC!
If he has one he has at least three. It all just sits out in an open field. Amongst all of it are two D-21's. Not sure what vintage,,,, can't get close enough. The guy is half a bubble off of full plumb. I've known the family for many years. The rest of them are all nice. And they all have a retraining order against them to not show up on the property. Yea, really. 

So what I'd like to know, if it's even possible, is there anything common on what, if anything that fails on these big monsters? It was such a shame to see them there. 

Any and all input appreciated.

	They weren't any too strong in the final drives/bull gear area. Bad enough at 127 HP. Even worse at 160 HP. More weight usually means more problems.

	OK, thanks. I don't live in that area anymore, but I do go down there on occasion. I've never approached him about them, but it's seems that it's now time to do that. It will be interesting how he responds. We know each other, but still...........

	Never hurts to inquire… I had an I-400 given to me about 20 years ago, after I finally decided to ask the guy about it. Drove by it every day, and when I bugged the owner about it one day… he told me “I’m never gonna do anything with it… if you want it, get it out of here.. you can HAVE it!” You really never know until you ask Edited by RedHeeler79 - 05 Dec 2024 at 5:42pm

	Here's another way to start that conversation: Visit or call him, tell him you're considering adding a D-21 to your collection, and ask HIM what common problems he's found with his. Hey Doc- The D21 rear end... when guys build kilobuck alky engines for pulling, what do they do to keep those rearends from becoming raw materials?
	Ten Amendments, Ten Commandments, and one Golden Rule solve most every problem. Citrus hand-cleaner with Pumice does the rest.

	A typical D-21 on the farm weigh's 14K or more and pulls a 6 or 7 bottom plow at 4 to 4.5 MPH. On the pulling track the most common chassis weight is 7K. I know of a couple that are down to 5.5 K. Speeds are anywhere from 45 MPH to nearly 95 MPH depending on the class. Tire tread height is always less than 1/2" inch. Modern pull sleds start easy to let the wheels spin from the very beginning. Failures in pulling just don't seem to happen because of the light weight, high speed and very short tire tread bar height.. Edited by DrAllis - 06 Dec 2024 at 5:47am

	I remember a local guy that had a D-21 back in the 70's. It had 24.5 x 32 tires (full of calcium chloride) and inner and outer wheel weights. The tractor was turned up to about 180 hp. They complained it needed a clutch every year. The dealer dynoed it and turned it down to about factory specs. When they got it back, they struggled running their 3-row chopper and told the dealer to set the pump back to where it was and they kept replacing the clutch.
