The 4010 also has 2 different sets of axel housings the lighter set is supposed to be around 100lbs lighter, just depends on how light you are looking to go.

I've heard that you have to measure how thick it is at the front of the axle housing but never got the measurements to be able to check.

Sorry, forgot to post that. Lighter housing is 1 3/8" wide, heavy housing 1 5/8" wide, measured at where it bolts to transmission housing

I found a 4020 I'm interested in buying to pull in a field farm class for now and collect parts to make it into a llss but don't want to screw myself if it's just going to be too heavy.

4020 just a little heavier . 4010 has 3 1/8 dia axles , 20 has 3 3/8 dia . little wider planetaries , 4010 HAS planetaries . Not positive but 4010 , 3010 , 3020 and 4000's ? are pretty similar axle dia etc . The 3 3/8 dia is 4020-4320 - 4430 size except for some later 44's with long axles .

Been 25 years ago, so this might be messed up.

I helped with a 3010 back half to a 4020 front half.

Am I remembering correctly, a 3010/ 4010 have a lighter duty PTO and hydraulics?

The big deal back then (farm class) was a top cover off a standard (wheatland) and a narrow front of a little MT. We had some running around with out a starter and batteries, roll start it down the ramps.
