We are getting ready to purchase asap. 3901 chassis just seems too small - probably would do the job but small and narrow. We live on a VERY steep hilly property where we need to rotary mow 8 acres a few times a year in our horse pasture and so some arena dragging and moving downed trees/wood regularly. We have 11 acres total. Our old tractor really bogged down on hills mowing so we are considering HST+ over the HST to help with this. Most feedback I see is that it helps with loader work which we will have a 4 in 1 bucket but really won't be doing a lot of loader work. My question is does it help in the hills? More interested in getting up and down hills without having to be in snail mode while rotary mowing.
It may depend on the tractor. We have a 59 hp 8000 lb. M59 Kubota and a lot of hills on our property. We are also at a moderately high altitude (7000') in the mountains. We've used HST+ now since 2008 and over 1000 hrs so do have some experience with it.
HST+ is a HUGE advantage on hills, especially if you are loaded. If you have ever used a vehicle with high/low transmission range then that is exactly what HST+ works like. It works like a regular 3 speed HST, but it has a separate lower gearing available in each range.
The advantage is that if you tackle a hill in too high of a range, you can simply shift down to a lower gear in that range with one finger using the lever right there on the steering column.. The HST plus lever looks like the directional signal on a car. No stopping is required to shift to the lower gear, and the shift is very fast. Not quite instantaneous when you are loaded, but still plenty fast.
Setting up for fast shifts does require that you balance the pedal, HST attack mode, load sensing, and response speed for fast shifting, but those are operator controls made via the knobs right there on the dash.
Set those right and it doesn't even require that you let up on the throttle. You move your fingertip and the tractor shifts to a lower range. It's as simple as that. I've never had it miss a shift.
You may want to put some thought into HST+ for the advantage going DOWNHILL. There are times in 4wd going downhill when a quick shift to a lower gear is priceless. HST+ can do that - but I still wouldn't bet my life on it. I start downhill in a low gear and stay there.
HST+ is equally helpful when doing loader work because you can drive the full bucket around in a high or medium range for travel speed to the dump site, and then as you push into the pile a flick of the finger shifts from high speed into high torque gearing.
Caveat: I have no idea how this feature would work on a smaller HP machine. Any convenience feature is bound to eat up some power. I just don't know how it is on a 30 hp tractor But for the over 55hp tractor HST+ works for us & is a must have feature for us from now on for HST. Someday I'll have to try Kubota's Glide Shift in the hills and see how it stacks up. GST has more ranges and more total gears so it might be as good or maybe better.
On the 4n1 bucket. I was going to buy one initially, but didn't. Yes I think it would be useful sometimes, but I think there is an argument for the standard lighter FEL bucket on hills. So I know nothing except I'd love to try one. The M59 with short wheelbase and 4000 lbs lift on the FEL should be able to handle the 4n1 weight. Maybe I just don't know what I'm missing, though I'd still want to keep our standard bucket. If anyone wants to loan or sell us a 4n1 to fit the M59 I'm interested...
And finally on mowing. Frankly if I was doing as much mowing as you are talking about I'd be looking at a VENTRAC or something similar with ultra low center of gravity that is made for doing that. Tractors and hillsides scare me. Nothing wrong with having two machines.
Good Luck,
