Hmmm, Kubota lawn tractors..... I always have something to say about that topic.
Worse money I ever spent. You can search for my previous posts, but to sum it up: lousy ride and lousy cut.
I just got my G2160 back from the dealer where they put hi-lift blades on it and readjusted the deck and I thought it helped some, but it still looks like I am trying to stripe my lawn or cut it at two different heights. Apparently the deck design just doesn't suck up the grass that the front tires push down, and I was overlapping my cut last time by 1-1/2'! That'll add "seat time", but I'm one who would rather get the job done quickly and move onto other things.
They also tightened the adjustable seat down to make it non-adjustable and that got rid of the shaking around due to the loose framework and an admitted poor design by Kubota. My model is two years old and this may have changed.
The idiot light to let you know when you are low on diesel is only visible if you mow your lawn at night or overcast (rainy /forums/images/graemlins/shocked.gif) days, but this is minor. Still, it's stupid.
The deck had two or three recalls in the first year, so I would make sure your dealer covers trucking if it needs to go in for warranty work. The place where I bought my mower didn't.
The engine really vibrates and runs rough at anything less than 1/4 throttle, but it DOES run strong and the tractor doesn't seem to bog down no matter what I'm cutting. That's a plus, but other 21 hp lawn tractors may do the same.
My yard adjoins the neighbors on either side, one with a JD and one CC riding mower and their yards look better than mine after we are done mowing.
Oh, and as far as the GR, when I had mine in for its 100 hour and getting the new blades..... there was one sitting there that the owner had just brought back. I was told he left with one like mine (newer model) because he kept getting stuck with the GR. I can only assume he expected more from the 4WD model and figured it wasn't worth it.
I do not see me owning my G2160 after this season and really only bought it because I figured since their tractors were so good, so must be their riding lawn mowers/lawn tractors.
Take my post for what it's worth, but once the novelty wore off I realized I had made a mistake.
