My B2910 HSD tractor has a clutch. IF no clutch, it amazes me that Kubota would allow the tractor to start if not in neutral. They do not do this on my BX2200, which has no clutch. It must be in neutral to start.
MY B2910 will also not start if the directional pedal is not centered (or PTO engaged). But maybe with the with LX they feel the seat presence switch eliminated the need for the tractor to be in neutral.
Personally, I would not buy a tractor with no clutch, if I ever had a chance of needing to use some implement like a post hole digger. AND since I have failed multiple times at prediction the future, I would therefore NEVER buy a tractor larger than a BX if it did not have a clutch. But this is just me...
In case I was not clear, if I do not push in the clutch with my B2910 it will not start...period.
