I’ve never posted on a HST v gear or tire v tire thread and I may regret this, but...
I like my Kubota. Grew up on a farm driving nothing but gear drive, non-shuttle, 2wd, R1’s. I don’t do that now. I’m not a farmer and don’t care to be. At the rate I’m going so far I only put about 200hr/yr on my tractor. But I have some acreage to care for and I need something to do it with. A 75hp tractor wouldn’t fit on the relatively narrow sidesloped trails down the almost sheer drops into the creek bottom and wouldn’t fit in the orchard areas that have to be brushogged. A small B wouldn’t have the PTO HP to run my chipper or drawbar HP or weight to skid logs up the steep trails out of the bottoms. I don’t do tillage work. My tractor has cruise control; tried it once on the road driving to a friend’s house to do some grapple and chipper work. Don’t have a field big enough to use it otherwise. I don’t do ag type spraying so precise speed control is unimportant. PTO HP on HST v gear in the L4701 is less than 2hp, but gear is more efficient. Maybe gear drive would give me more drawbar HP, but so far in low range I’ve always run out of traction before I ran out of torque so I’d need to change tires before I could blame the transmission. So far as drawbar HP at tillage speed; again I don’t do tillage so I don’t care. The R4’s are better for about 95% of what I do as they don’t tear up the ground like R1’s. For the other 5% what I really need to do is get a small dozer.
We all have problems we address with equipment. Our problems aren’t the same so it makes sense our equipment isn’t the same. I really do like my open station L4701 HST with loaded R4’s for my needs but I wouldn’t recommend it for a lawn mower, or chisel plowing a 200 acre field, or running a baler in a serious hay operation, or blowing snow in sub-zero temps. Conversely I have no use at all for a 19hp tractor or a 90hp tractor or anything with a cab. Nothing wrong with them, there’s just nothing I need that they could do.
