the 4620 is so nimble and easy to operate.....it musta been so awesome to buy one in 72//hinson cab, AC, and powershift.

we dindt bought it in 72, but it was equiped with a cab (dont know what brand) and ac. :P

it only doesnt have a differential lock..

The 4620's engine is intercooled while 4320's is not.Same 404 cid tho.

[JDRobin86]

the 4620 engine is turbo build, the 4320 isnt. a 4620 got oil cooling beneeth the pistons. a 4620 got an 404 too, but they have got a distribution driven fuel injection pump

Running in 6th gear......a little too high and it's causing the engine to lug a bit. Try 5th gear and you'll get a lot better performance from the tractor and the harrow!

I dont know much about those discs, they made al lot of different types. This is a BWA, probably 20 feet.

All cilinders shoud fit, but they are not exacly the same. the cilinder on our disc is a home made cilinder. this machine was owned by the Dutch governement in the 70's. They had different brand of machines, and they want one cilinder to fit all the machines, so they did some word on the construction.

@brian93ist

we've done a few things on the engine. like new cilinders, liners, piston rings, crankshaft, turbo, radiator, injectors etc. The only thing we now need to do is take care of the fuel injection pump.

It gave us 130hp on the dyno, so that must be about good. it is smoking because it is under 1500 rpm

@jdng11 at a junk yard where they have hundreds of tractors you can get them but you will pay a price for them
