Ahh...the great struggle...which machine to buy.
I pride myself on being able to rattle off exactly what I would purchase if given X amount of dollars to spend on a machine to accomplish any given task.
In other words, I know what I would replace my current tractor with. I know what tractor I would buy if I was my neighbor, who farms 50 acres of produce...I have favorite tractors in any given market segment. A tractor know-it-all.
In the class that you're looking at, I am currently like a rudderless ship. I don't know if I would buy green or red or blue. I really like the engine of the new Deere, great torque. I really like my local Case dealer, outstanding service. I also really like the New Holland's Super Steer axle, fabulous turning radius. Which would I purchase, the 4720 or the DX55? I have no idea.
Drive them both on YOUR property. Any dealer should be willing to do this for you. If they aren't, go elsewhere.
You have an enjoyable task ahead of you. When you are done, you will know with confidence that you have the best machine for your needs.
