let's see....
I average about 400hrs/year on tractors (conservative # for a part-time farming operation). I use mostly one tractor, but always have had 2 or 3 on hand. All with dry clutches.
x about 25 years = about 10,000 hours of tractor driving.
One clutch was replaced in the Deutz 7110 after about 3000 hrs use by me and I don't know how much by the previous owner. Lots of loader time and baler time. Relatively very little tillage overall. So I'm guessing that clutch lasted more than 10 years. I was a little disappointed.
I have driven many hundreds of thousands of miles in standard shift pickup trucks. Probably way over a million miles. 2 clutches. One in a Dodge and one in a Ford. Oh, and replaced another in a GM as preventative maintenance since I had the tranny out anyway. I have an automatic right now. Easier to drive. Not even close to being better for driving. NOT EVEN CLOSE.
If you know how to drive and are physically able, having HST or gear should not be the issue. Buying the suitable machine should be. In the OP's case, I believe he will appreciate the extra weight, torque, capacities and overall build details of the RX far more than he would HST.
One day I will probably have HST (when I retire). I felt my knee just the other day when I was having to clutch lots. I don't have a clutchless reverser in my DK or my Deutz. BTW, this "sync shuttle shift" thing is not even as convenient as simply having a reverse on the regular gear shifter (comparing the Kioti to the Deutz or to any other tractor I've owned). At this point I would far rather clutch than listen to a whine. I am sensitive to buzzes and whines. They grate on me over a long day and exhaust me eventually.
IMO, the best series of tractor Kioti builds are the RX models. Many here buy the NX's instead. IDKW. Why would you want a lighter-duty tractor? I guess there are reasons, but most here choose the HST over the gear because they can't drive a clutch, IMO. A clutch in a tractor is easier to operate than in a car. Easier to wreck too....
Anyway, for those who care don't overlook the RX simply because of the HST thing. Don't.
Like I said, HST is neither "more accurate" nor "faster". That is BS. Less work; maybe. Easier to drive; maybe. "more accurate" and "faster"; I don't think so. Just don't let your foot slip off the clutch pedal...lol.
Another thing; these dinky little high revving engines are not the way to go in a tractor, IMO. Big engines turning heavy parts slower produce more quality torque for tractor work. The numbers do lie. I think my Perkins makes max torque at about 1350rpm or so. I think it makes more torque than many higher HP tractors with smaller displacement engines (like an M108S Kubota, for example). I like that. It is relaxing to drive when you can loaf along sometimes. Six cylinder tractors are nicer to drive than 4 cylinder tractors, IMO. We are going through a period where tractor engines are getting smaller and smaller and producing more and more power/inch. Power, not torque. The "feel" and capability is not the same.
Low RPM torque is always your friend and so is weight (almost always).
The plethora of HST machines on the market is due to market demand who are mostly non-equipment operators getting a tractor for the first time. Not due to "more accurate" or "faster". And let's be real; if it indeed does take a 1/2 second longer to change direction and you change direction 1000 times that works out to 500 seconds. Is 8 1/2 minutes in a 1000-direction-change day a lot for a weekend warrior? I spend more time than that in a day scratching my nuts and figuring out what to do next, lol.
Be safe out there!
