Another 2120 Turf to Ag switch

[dogbreath108]

Shaley,
Did they give you a price for front centers (or even the whole wheel) using your prints?

Here is a photo of my stock 28" (a bit rusty and not even calcium filled) rears. Probably the most common on the 2120 (I think), although I have seen quite a few with the sizes that smac has...

Joe, I see, you have the disc just need the rim with clips.
I plan on getting a quote next week. The last hurdle is how to cut the centers from the Kubota R4 fronts in a concentric manner. Looked at laser and plasma but I think a rotary table and 3/16 end mill will be the way.

farmerjim (and others),
Is tere a reference somewhere that documents the differend 4wd tractor models, and front/rear tire size recommendations?

I recently scored a new pair of NH 8x16 ag tires and rims, thinking they would replace my worn 6x16 ag set. BUT they are not only a bit wider, they are almost 3" larger in diameter. Granted my old 6"ers are well worn, but I doubt that would account for all of the 3" difference.

just got a message from the agco dealer that my blank 8x16 rims are in... I'll have to pick up next saturday when I get back my work trip during the week.

My machinist friend (who is much smarter then me on a whole bunch of things) said to me, "just chuck the center in a lathe, and cut the old rim off"..

I'm thinking, ok,... sounds good!

I'll probably try in a few weeks..




shaley, make sure you let me know how you make out... I am interested...

Here is the plan. Tomorow I make the 1 hr. drive to Harry's tire Wheaton Ia and pick up the rims. 28" rears $100 ea the centers to match $110 ea and blank 6x16 fronts for $33 ea sales tax free for ag use. I have a machinest friend that will make adapters for the rear almost exactly to your drawing Shaley except he thought he would turn the new pilot hub from the 1" steel instead of adding on a 1/4" disk. He will also make from scratch the centers for the front, either 1/2 or 3/8" thick and weld them in with the right offset (Harry's would have done this for $167 to my spects rim price included) I also found the rear tires for $250 ea and they are the old style ttr Firestones, the fronts are $120 ea. I decided to go with the 8-16 6 ply, they will match the rears. Most info I have show to use 8-18 or 9.5-16 both have a circ of 99", mine will have 93" circ. the math is near perfect with what has been on the machine for 11 years. I think this should be OK with the mechanical FWD. Anyway that is the plan if anyone sees a problem or has a recomendation Please speak up Everyone on this forum is smarter then me about this stuff. Thanks for everything I hope to have just under $1700 for the total switch and still have a full set of turfs in the shedd. it will probably be mid January before it is all done, I will post before and after pics. smac

SMAC, You can get the 16mm x 1.5mm pitch x 40mm Lng. from Mcmaster Carr supply. McMaster-Carr
If you turn the pilot, make sure the material is thick enough to bury the SHCS below the surface. Keep us posted.

smac, sounds like your Harrys tire has some great prices! Very eager to see your results.

I also have just picked my blank 8x16 front rims from the agco dealer today. They were ordered unpainted (just as I wanted) for just over 50 bucks each. As much as I would like to start on this project today, it doesn't look like I will start for another week or two...

Also after thinking about it for a while, I would like to have the front centers bolt on rather than weld them as I could buy another set of 8x16 blanks for some r-1 tires... At this point, I don't know if this would be possible because the factory centers have quite a dish to them. This would make bolting to tabs or a welded ring difficult to say the least. If you guys have any ideas, let em fly, it would sure help.

Maybe if the flat centers that you guys are making work out well, I'll just have a set of those made for the second set of rims...


One more thought... Isn't the steel used for rims a different carbon content (or other composition) than regular mild steel? Somewhat tougher is what I am thinking. When I was a kid, we used to get much more scrap money from rim steel than other generic scrap steel. And it only applied to rims (at the time we only got auto rims but thought it applied to all rims).. Do you know if this is true???

I've been sidetracked by a hardwood flooring project that I promised the wife for xmas. I'll get back on this in Jan as I have already purchased the rims and tires. Please post on your experiences on the best way to remove the old center on the fronts. Thanks
