I think You are doing what you accused others of doing "putting a plug in for you favorite machine"
I don't care what brand a machine is. I want the best machine for the job.
John Deere and Komatsu has came a long way the last few years.
In the smaller Dozers from my experience John Deere is better than Cat.
Larger Dozers it is between Cat and Komatsu, John Deere just does not have a big machine.
I just ran the new D7E and was impressed with it and it will be interesting to see how it stands up in the long run.
