They had a couple mower options for my L3540. The mid mount would have been totally ridiculous. The LT1050 works just fine for anything I have to mow. Which, I haven't mowed anything in a while.
Be wary of the earlier L40 Grand series tractors. 07-08 era. They used some crappy components on them. Toasted the two tilt cylinders within a couple weeks after buying this NEW. They bent like wet spaghetti, and cylinders are not covered under warranty, so that cost a pile.
They had bearing issues in the rear end and one of mine split in half. It wrecked a lot of stuff and cracked the housings. That was covered under warranty, but if not, would have cost a pile. About 6K. Kubota couldn't back out of this one because it was happening to a number of rigs.
