Hi, I'm trying to decide what would be a better choice. I have a 466, and I'm trying to decide if I should put it in a 4020 or a 4230 or?

I have an early 4020, that I've already pulled with. It has the original 404 with a 4320 turbo setup on it, but I'm willing to sell it, and buy a 4230 or 4430 to put the 466 into, or is it a better choice to put the 466 into the 4020?

I really would like to have a Generation II tractor like the 30 series, but have to make a descision on it.

My 4020 is a good looking tractor, and in nice shape. Although it would hurt to do it, I'm willing to part with it for a 30 series tractor.

I'm interested in anyone's input.

Thank you!
 
Would be easier to put in a 4230 not saying the 4020 won't work.Put a 7700 turbo 404 in a 4020 allot of modifications.
 
What classes do pull? Around here they would only let you run 11500 lb and up with a newer engine like that in it. If the let 1066's with DT466's run 9500 around you then you running a 466 is only fair. That being said back onto topic.

I currently have two 4430's I pull with and have worked on a turbo'd 4010. A syncro 4430 and 4020 are basically the same trans with some minor changes, the will both take the same kind of power, same goes for the 4230.

The 30 series tractors have a lot more room under hood. After the water manifold is remade to work with larger turbos. A 4430 with a 55 series exhaust manifold, a hx60 with the custom exhaust housing will fit under the hood no fuss. A 4230 has a slightly narrower hood and the whole thing, platform, etc.. Sits 2 inches lower, but still has more room than a 4020.

The 4020 is lacking a bit on the under hood room. On the 4010 we had to modify a 4430 manifold to fit the hx52 we wanted to run and clear the hood that had previously been raised a half an inch. Had to cut the whole turbo flange off and weld a new one on lower, not the easiest of jobs. Plus the oil drain gets tricky and the water outlet manifold has to go and a low profile one fabricated.

The 4020 clutch is dry, a good running 466 will toast a single disc clutch real fast. Two discs are considered a minimum. If is a power shift I wouldn't even consider putting a 466 in it and pulling with it.

The 42/4430's are wet clutch machines. I would take a quad range tractor over a syncro for pulling every time. I ran my one 4430 till I broke the trans pulling road gear, broke the syncro shell and high range pinion. Never had trouble keeping the wet clutches holding, did wear the main clutch out once.
The wet clutch can be setup as a 3, 4 or 5 disc clutch depending on what power level your at. The 3 disc keeps the pto separate. The 4 and 5 disc tie the drive and pto clutch together and by doing some hydraulic mods on the clutch valve and the clutch piston housing both Pistons will operate on the clutch pedal, turn the pressure up to 200 psi and it will hold more than the trans will. The clutch count in the quad pack can be increase to hold more power very easily.
 
Just moved here, not exactly sure of all the rules yet, but I
guess it depends on what class you want to pull in. Antique
classes around here cut off at 1964, so that throws out the 30
series. I wouldn't pull an antique class anyway.

I know what you mean with more room under the hood, and I
don't think there'd be radiator/fan issues with a 30 series
either.

As for the multiple wet clutches you're talking about with
adding extra disks, I'm not that far along yet, I need to hang
out with someone the next time they do it! Lol! Much to learn!

I like the idea of pulling with a Quad, my 4020 has a synchro
range, not Powershift. And it has a single disk ceramic button
clutch.

I agree if they're letting DT466's I'm 1066's pull, a Deere 466
should be allowed as well!
 
I agree. Find a 4230 or 4430. If your running mph classes get a quad, if open speed a syncro Is ok, quad will work too but may take modifications if running big power. You can weld clutch hubs together easily enough and have a 4 disk clutch with other modifications.
