Personally if I were going to be mowing 30ish acres…not sure what OP really mowing, but if I were going to be on it all day mowing, I’d rather have the geared machine. (I understood OP did not say mowing 30 acres)
couple reasons for me…
1. my MX is HST (which I would absolutely buy again) has a throttle lock (cruise, but to me it’s a throttle lock) which I am glad I have, but when I do use it, id rather have it an a gear and not have the throttle lock.
2. IMO HST, at least on an open station generates a lot more heat to the operator…is that true or not? I never measured, but it sure as hell seems like it generates a lot of heat on the operator relative to a geared machine. Maybe someone with both(or similar) in same machine would weigh in on that.
I’m on and off mine a lot so I only notice the heat when I mow a pasture for hours at a time. Point here is I was going to be on all day I’d maybe think about which yields less heat to the operator. (And yes I have previously been too cheap to buy a cab, but it be a consideration for HVAC if I were going to have long days on it.)
just my opinion.
