4010 vs 4020

[stieger]

was there a large difference between the 10 and 20 series? I thought the look pretty similar. wasn'sure what made them different. Thanks for any answers.

4020 engines are bigger.

4020 has a better PTO speed change. The 4010, both front and rear PTO are the same speed as selected by the bolt on stub (which if it comes loose can cause a lot of damage). The 4020 the front PTO always runs 1000 rpm and the spline insert changes only the rear PTO speed.

The early 4020 has a different remote hydraulic connector on the back. The late 4020 has totally different hydraulics.

The 4020 can be had with power shift transmission.

The 4020 can be had with differential lock.

The late 4020 engine has no weep holes and has no crancase ventilation pump.

A few 4020 were sold with a hydraulic front wheel assist.

They do look the same though the late 4020 also uses an oval muffler for blocking vision a little less.

4010 has a 3rd reverse. 4020 has two reverses. (synchro xmsn)

The 4020 still has 3rd reverse,,you just need to knotch out the shifter so it will go in, I do it to a lot of them makes it nice when moveing round bales off the field...

4020 has thicker axles, maybe sturdier transmission parts. The 4010 third reverse was fast and was easily broken if worked too hard. So they changed the dash shift lever mechanism to lock it out like 4th reverse is locked out in both models.

It's more a 4010 vs. early 4020 vs. late 4020.
Then again how about looking at a 4230? Much quieter cab on a refined 4020 chassis.

Looking at the specs you realize that the 4010 really falls between the 3020 and the 4020. The 4010 was rated at 81 PTO HP from a 302CI engine, while the 4020 was 95 from a 404. The 3020 is 227 CI putting out 71 PTO HP.

the early 4020's and 4010's are comparable. The later 4020's are great tractors and you dont really see anyone who doesnt like theirs. Thats probably why they sell soooo high compared to most tractors of that age/size/hp.

Because they were so compatible with so many different operations most of them have been worn "out" two or three times. I have about 250 4020's in my area that I keep in repair, some of them have the grooves on the clutch pedal worn down smooth, makes me wonder how many "million" times was the pedal pushed.. They were actualy over enginered for the times and HP that they started out with, and very easey to repair, one of the easeyest tractors to split for a clutch ever made. Because of all this they continue to hold there value and respect like no other model ever will.... There are 'many' parts and components from tractors 30 years newer the will inter-change on them, engines,pumps and even transmission parts,,when you watch a "HOT" pulling tractor with 1,000 plus HP screeming down a track with new model sheet metal on it chances are strong that there is a 4020 transmission under it handleing all that power, I'ts amazeing...

(quoted from post at 07:44:14 10/24/09) Looking at the specs you realize that the 4010 really falls between the 3020 and the 4020. The 4010 was rated at 81 PTO HP from a 302CI engine, while the 4020 was 95 from a 404. The 3020 is 227 CI putting out 71 PTO HP.

Your comparing a 4020 diesel to gas engines in the 4010 & 3020

JD 4020 D is 404 cid but a 4010 D is 380 cid not 302 cid & 3020 D is 270 cid not 227 cid

Most 4010's have had 4020 piston & sleeve kits installed but that still won't make them a "4020"

We have an early 4020D and a 4010D, the biggest differences I have noticed is the PTO lever swapped sides and the grease fitting on the PTO clutch bearing was moved to the outside of the tractor which seems to have caused it to get greased more often. And the 7th gear reverse being blocked off on the 20. They are both still the main tractors on the 140 acre cattle farm.
