OK, it sounds like we really need to understand the differences in the 5525 and 5603 vs the 4720.

4720 - largest of the "compact utility tractors" that John Deere offers.
Standard "4WD" which is also known as MFWD - Mechanical Four Wheel Drive. I guess they had hydraulic at some time - so they call these Mechanical.
Standard e-hyrdo transmission: pedal forward, pedal back - 3 ranges - no clutch.
Available in a cab
58hp at flywheel - 50hp PTO
5603: I have not seen one yet, but the "03" series is more of a value line. All tractor - good, time proven technology. I see the 5603 has power reverser available. That trans it not available in the other 5x03s.
Has a clutch, but easy to go from forward ot reverse.
Available in 4wd.
Available in a cab
This tractor is new this year.
JD dropped the 05 series which had 4wd available. First year for 4wd on 03s.
99hp at flywheel - 82hp PTO
5525:
More delux model (more features available and standard)
Available in a cab
Available in 4wd.
91hp Flywheel - 75hp PTO
I think I covered most items between them. I am sure I missed something.

My biggest gap is in figuring out a comparable to the ehydro - which seems to be the most "automatic". So when I go to the JD "build your own", I cannot figure out how to pick the right features in that realm. As I am not very good at the clutch work because of an injury, it would be best to get as close to that as possible.

E-Hyrdo is as close to an auto as you are going to get.
4720 is the largest one available with that options.
The closest you will get to an auto with a clutch is the power reverser - east changed forward to reverse, but you still have a clutch.
If not clutch is the deal - you are looking at a 4x20. Now, when you are comparing prices on the various models (cab is only availalbe in 4320, 4520, 4720), realize that e-hyrdo is not standard on all of them. Power reverser migth be standard which would have a clutch.
If you recall, we started looking at the 4320 with cab and have continued to go up in HP. Based on all this great input, we are stretching every penny and moving up in size. We have also decided on the R1 tires (interesting how many dealers push the R4). However, we MUST have 4WD. (Hills, snow, mud, etc.) Is the MFWD the same thing?

When I was comparing the 4320, 4520, 4720 open station models, there was around $1200 between each model. Make sure you are comparing apples to apples (transmission is the only big thing on this series).
There are so many options. I suspect any 4x20 cab will do what you want to do. You will have sticker shock. I did when I built some of the bigger tractors and they were cheaper, but the 4720 is hard to beat - they come loaded. Everything else is an option on the bigger tractors.
