Can you provide even the tiniest bit of fact to back that statement up?
I actually own one of these tractors. In fact, a 2008 5303. It's a simple and stout tractor. It is about 1100 lbs heavier than the Kubota
M5040 I looked at and uses the 2.9L Powertech 3029 motor that is well proven.
Pound for pound, this is one of the best deals JD has going. I started out looking at the 4000 series Deeres and found this to be a substantially larger tractor for substantially less money, albeit with less creature comforts.
Here are some numbers from January of this year from the Deere Configurator:
$32,629 -- 4720 Open Station
$40,499 -- 4720 Cab
$24,474 -- 5065E MFWD (5303 equivalent)
I have never once regretted buying this machine, and with a little searching, I suspect you'll find similar sentiments from other actual owners.
