I opted for the gear model (2615 4WD) in early August. I've been well pleased with it so far. I need more seat time, though. I only have about 20 hours on it. I've gotten lots of use out of the FEL (I do wish I had a toothbar on it) and recently purchased a KK 5' rotary mower.
I gave the 5' rotary mower a workout yesterday afternoon mowing below the dam at my dad's pond. The tractor and mower both performed very well even when cutting 2"+ pine, sweetgum, and sandbar willow saplings. I only had the tires turn loose once going up a fairly steep slope. Engaging the rear differential lock stopped the slippage and pulled me on up the hill. There were lots of spots where the slope was more than I was comfortable mowing, so I left it for manual work with a slingblade or trimmer with a blade.
The tractor/kutter survived it all wonderfully. I, on the other hand, now have raging allergies! I went and got a steroid shot this morning and am feeling much better. I've got to start wearing a dust mask when mowing in extremely dry conditions!
Later,
