4520 deere?

[Pawel]

Hey guys I"m looking at a 4520 deere with a completely rebuilt powershift transmission. It"s a 1971 model, any problems with this series or model? All I know about it is that it"s similar to a 4430.

The guy wants 9500 CDN for it, is it worth it or better to leave it be?
Thanks in advance.

I dont think there were any real problems associated with them other than the air cleaner problem from the factory. I believe that most of the 4520 tractors were updated with 4620 parts minus the intercooler. They are really not so much like a 4430 other than the fact that they are around the same horsepower and carry the same cubic inches.

4430
oil bath clutch
540/1000 rpm PTO
Different engine (still 404)
16 spd. quad range offered

4520
Dry traction drive clutch
1000 RPM PTO only
8 spd. synchro or 8 spd. pwr. shift





Set aside the SGB and I might rather have a 4520 than a 4430?.....Maybe

As for the value of the tractor....It is too large to be a chore tractor, and too old to be modern enough for row croppers. You should be able to purchase one for less than a 4020

Thanks are there any easy points to identify whether or not the motor"s been updated to a 4620 motor specs?

The 4520 is a larger frame tractor than the 4430. It had a category II-III hitch, 100mm axles, and quite a bit more weight in the frame. I had one years ago and it was a bit underpowered for its size and weight. I also had a 4620, which is identical except for the intercooler. The smaller framed 4430 is a more versatile tractor.

4520s were replaced by the 4320 in 1972. they used the same exact engine as a 4020 but had a turbcharger. 4520s had major breathing problems that were fixed in the 4320. 4320s had a larger block with bigger intake and exhaust ports. 4320s were still a 404ci, but the block was physically bigger with 4020 sleeves. my uncle used to have both a 4520 and a 4320 and the 4320 would outwork the 4520 any day. i think it was a little easier on fuel too

Wrong, wrong and wrong again. The 4520 was replaced by the 4620, not the 4320, and the 4520 and 4620 are about as similar to a 4320 as a 4020 is to a 3010, which is to say not at all. And no, neither the 4520, 4620 OR the 4320 used the "exact same" engine as the 4020. The 4320 used the "Turbo-Built" version of the 404 used in the 4020, but it was improved across the board to handle the extra horsepower and load of a turbocharger - revisions to the cooling system, addition of piston-cooling jets, improved lube system, etc. etc. etc. And the 4520 and 4620 were completely different from the 4320 engine, as well. Aftercooled, yet more improvements to the cooling and lube systems, etc. etc. etc. The extent of similarity in the engines from the 4020 through the 4620? Bore, stroke and cubic inches.

can you do some dealing on the price?
the brothers i worked for had 4520 it was turned up to 150-155 horse.
that tractor was a real brute when it came to work it could have been better on fuel though.
