choosing the right one

Looking at two older John Deere tractors; 2640 Dubuque model and a 2555 German model. They both have been sitting for years and now each has leaking injector pump. The 2640 has a roosa master pump the 2555 has a lucas pump. Is one preferred over the other with respect to birth and or pump brand? Has anyone had any hands on experience with either? Thx for sharing your knowledge.
 
Pump wise it’s possible the Lucas might be slightly more expensive if you have to take it to the pump shop but it’s generally a copy of the roosamaster standadyne I believe. I’m assuming it’s a 2555 setup like a 2640 with batteries under the hood no cab and a two levers between your feet with no left hand reverser? I think reverser was still an option in a 2640 just not quite as popular I’ve seen more with 2 speed more 2555s with reverser

Even if all things were the same I’d still pick the 2555 with the better parking brake and turbo (zoom zoom)

If either one of them has a 146 loader instead of the 175 mine has that wasn’t very popular I’d pick that 146

55 has a better loader plumbing plan both my old one with 146 and new one have the 4 hose manifold up front

There’s significantly more advantages for the 55 series if you pick some of the other options BUT they were not made here and my uncle is still upset 50 years later the other day about it moving to Germany and how they weren’t as popular (not much in the 80s was very popular and Dubuque had made some stumbles)

But overall it’s a better tractor even down to operating implements with my 2 12 volt batteries I can run things off both sides

You can get a big led light bar to go in the front of it that fits nice into the hood

The 2640 will have less electronic gauges that is an advantage but it’s about the only one

Neither of them are the quality of a Waterloo tractor and as long as you understand that there isn’t any reason not to own either
 
I prefer the 2555 over the 2640 due to having trans shift levers & IPTO control lever moved forward from trans hump making it easier for tractor operator to mount/dismount tractor.

But 2640 has a larger displacement engine 4.5L(276 cid) naturally aspirated vs 2555 3.9L(239 cid) turbo-charged but both are advertised @ 77 HP. 2550 could have option of TSS(synchronized) trans & 55 series would have ISO breakaway couplers VS old style JD couplers on 2640.

According to Tractotdata.com 2555 weighs about 400#s more than a 2640

FEL hyd connections between both models should be almost identical.

The 55 should have option of tss as well I believe that’s what mine had levers are on the rh side go down to the transmission similar to a 3020

It keeps the dirt out of the trans those boots when they fail collect an amazing amount when doing hay

If he is comparing the 2 I was making the assumption that it wasn’t going to be outfitted that way

I believe I did actually like the 2640 pto with brake better than the dual stage left foot pedal on my old 2555 but new one with that better transmission has a completely independent pto lever up front like a 4440

I’m not sure if many of those options are on open station but maybe
