I bet every time it has a flat tire, it’s the very inside tire. 

Its always the inside dual 🙄😖

Seems like there would be a lot of load on the axle

Back in the early 80s a couple of guys in my neck of the woods bought 6030s, tuned 'em pretty warm, and put triples on.

Both of them broke axles.

I knew it would happen on a John Deere

Where I was in ND (🥱🥱) in 2003 they had 2 John Deere 9520s on triples.

I seem to remember  there was a fault code pinging up on one of them that resulted in it being hauled off to Jamestown  query a rear wheel bearing failure.

Turned out to be the centre wheel was loose.

A guy here bought a 4840 in the late 80’s that had cast centers for duals, and decided that it didn’t have enough floatation, so he put triples on instead of replacing the cast centers with pressed steel. It lasted a year and the next year he had pressed steel for duals after that.

Dad welded up a pair of clamp-on duals for the '51 M to plant corn with about 1964 or '65. Ran the M planting till '68 when we first got the SH, by spring '69 we had home-made clamp-on's for the SH.

   First set of duals were M&W direct axle 12x38's Dad bought for the Super-M-TA to pull the 14 ft Krause disk. The M-TA pulled it O-K in stalk ground, ran in place in plowed ground.  Had to carry the disk a little bit in plowed ground even with the duals.

   I imagine with a big enough 2WD tractor, 150+ hp triples would be a benefit. The BTO I worked for never had any duals, ran 18.4x34's on everything except the 2470 Case, it had 28Lx26's.  The Landlord with the 8440 Deere had factory duals, 23.1x30 or '34's, I forget which. It would spin all 8 sometimes if the Glenco Soil-Saver settled in too deep. It had 8 matching GY Power-Torque tires around 60-70% tread, it slipped a bit all the time.  With the "Two Shank Too Big" soil saver We had to run A range all the time, just crawl along.  He made a comment to me once that sounded like it slipped even more pulling his field cultivator in the spring before planting.

The picture above is correct. In the Auction photo they put the right side decal on the left side and left side on the right. I have seen it quite a bit, but nothing gets me as much as people who put the Deere decal that is supposed to be on the back of the seat on a 4020 on the front of the tractor.

Being in MT, would they have run triples for stability? Because as mentioned, if looking for traction I would think they'd have found the limits of axle durability. Also, don't they have those floating hayfields in some parts?

My guess is they were trying to pull a bigger cultivator  than they should  have been. If duels won't keep you stable enough on a hill side I can't imagine triples would be that much better...

Also some parts of the state in a drought just turn to powder...trying to get the power to the ground.

The jd has a dt 710 in the center so it will be just like having duals once you deduct the available traction the dt710 gives it

I think if your getting to the point of excessive slippage of duals, it's time to trade up to a big Challenger.  My nephew bought a slightly used Challanger a year ago. I haven't had a chance to talk to him or his Dad but I suspect it's the smoothest riding tractor they've ever been on/in.  I think my brother-in-law's 4440 was his BIG tractor, pulling 4440-sized implements will really test how smooth that Challanger really is.

I’ve seen older smaller challengers for some pretty reasonable prices!
