I got a coupon from deere last year as well, 7k, off the best deal I could make trading my Kubota 7040 in on a 5100E cab. I looked at it and Hated the deere, shifter was on top of my leg, my feet were against the front windows, and I had to hike my legs up and back to reach the petals, very uncomfortable cab imho. The 12 speed trans in the deere was a 3 range x 4 speed, the Kubota was a 12 speed as well, 2 range 6 speed, allot less shifting. Also the eseries, the right cab door does not open and it had no mirrors.
I went to my Kubota dealer and mentioned the deal deere wanted to make, and let them think I was going to take it, and got my 9960 with 12 speed, and 2 remotes for less than deere.
The 9960 is a winner, comfortable and plenty of power. I have 400 hours on it in 9 months, and I was sick for 2 months, and hardly used it. it is cranking out 5x6 bales out of a Vermeer 605 k without straining, and the bales are bricks. It also runs away with an international 370 14' disc with 20" blades on it...I love it
