Both are good machines. Never driven either but have sat and looked at them at a local Kubota dealer. I've looked real hard at Kubota's before but never had that it factor for me.
I think the cabs on the comparable 4520 are much superior. You get a lot better AC and heat. I think its something like 7-15 degrees difference max for the Kubota and 30 for the Deere. So on a 100 degree day thats the difference of 70 degrees and 85 degrees - in the cab. That to me is just not acceptable for an AC unit these days. Also JD has the quietest cab in the industry and sealed air tight so if you have any allergies they don't get in - I can't confirm but Kubota's website doesn't mention this. Not to mention I like the look of JD's interior much better, just looks cleaner to me - but I guess that's an opinion.
Also the little experience I've had with a Kubota HST transmission with the single rocker that you tilt your foot back and forth is just not as nice to me as the twin touch. The new Deere HST have a lot of new improvements too. They have it so it is like a car where the more you push the accelerator the faster/more RPM's it will put out. Which is perfect for loader work. Its the easy use of HST with the power benefits of a gear.
According to the build your own features of both websites the 4520 Deere would cost about $2000 more than a Kubota. I had the CX loader for the Deere - another benefit with the self leveling over the Kubota's standard loader. But The Deere was about $45,000 and the Kubota at $43,000 from the build it yourself. A lot of times those prices are a lot less or more though.
Maybe this is just because I bleed green but when there's a better deal I'll say. The Kubota will definitely be less. You pay premium for Deere because they just go the extra mile. I've owned Deere tractors all my life without any problems. I've looked at many Kubota's and the price alone I'd have to go with a Kubota but The only place that Kubota has over Deere is the
M59. Deere just has no comparable. I would go Kubota there, Deere everything else. Something said about American design, engineering, and production too.
If I were you I'd look into a 4520. In my opinion a much better tractor for the minimal price bump. And a JD dealer will give you more on a trade in than a Kubota dealer would and more from a Kubota dealer if it were a Kubota. They believe in their product more. If 60HP with a cab is your goal I would get a 4520 with a cab. That's just me though.:thumbsup:
