Everyone seems to have an opinion on each brand. I personally bought a Kubota MX 5100 from Messicks. I have used it to its limits with zero issues. I think how a dealer treats its customers has a huge influence on the reputation of the brand tractor they sell.
For example, My Kubota showed up with R-4 tires. I was not thrilled with that but I didn't specify that I wanted Ag tires but i had to take delivery to dig my family out of the house from the 4ft. of snow we got hammered with in 3 days. I called them and asked what it would cost me in the spring to get the Ag's put on. they said "zero". I told them by that time i would have 100+ hours on the R-4 tires. Messicks said "No problem". The came and picked up my tractor (3 hours one way) switched out the R-4's for New Ag's and even split the cost to fill the rear tires. They then returned my tractor within a week.
This whole experience makes me 100% satisfied with my Kubota thanks to a great dealer...
Having owned tractors most of my adult life,and born and raised on a farm where I learned to drive a John Deere "A" at about 8 years old. I knew exactly what tires I wanted going in and told them.
Most dealers I have dealt with will bend over backwards to make you happy,that is just good business.It is true however that Deere and Kubota dealers can do this easier then most other dealers. After all you have just spent thousands more for their product,so they have more profit margin to play with. At times they seem to be really treating you good when in reality if they were treating you well they would have given you a better deal in the beginning.
The truth sadly is that you could have gotten a lot more tractor for less then you paid for the Kubota. You actually could have bought the AG tires with extra rims and had both with the money you could have saved buying the LS.
I am not bashing your Kubota,if you are happy with it great its a good machine. All I am saying is the pendulum is swinging and companies like LS have caught Kubota and are passing them and selling more tractor for less money.
I grew up I was a Pontiac man,I loved Pontiacs. About 1972 I started to realize that Pontiacs,where just Chevy clones,and where not of very good quality.This in my opinion is what is happening to the big 3 tractors. They are living on their reputation and selling a cheaper product at a high price. Eventually it will catch up to them.
