Horsejockey, for what it is worth, here is my version of how HST worked out for me. I have a twin pedal JD 510 mower, it's kind of a zero turn radius type. When I went looking for a tractor, I test drove several brands, Kubota included. Being familiar with the twin pedal on JD made it a natural for me to get on a JD 4600 HST and manuever almost like my mower. I tried the Kubota
L4310 at that time and found the "treadle" type pedal definitely different. My first impression was one of "well this is strange". After fooling around for about 30 minutes at the gracious dealers lot, I become pretty familiar with the treadle pedal. Long story short, the smoothness of the Kubota engine/HST combination sold me on Kubota. Now, about 3 years latter, I find control of the Kubota to be superior to that of my JD 510 only from the perspective of actively being able to control the speed while on rough terrain (kind of a "seat of the pant's" type thing). Other then that, I find the use of either to be a non issue Only one time can I say that the single pedal was of great assitance was when I was digging around a culvert with my
L48. Suddenly the front end dropped out from under me and I was going down into the ditch. I instinctively hit the reverse on the pedal just quick enough to hold my position, all four tires spinning wildly while I lowered the bucket and anchored myself. The whole process took maybe 1 second of time. Had it been a twin pedal like my JD mower, I may and I may not have hit the right pedal, there was no time to think, just do. After using the new design pedal on my
L3830 HST now for a year, I love it. When folks try out my tractor, some put their entire foot on the pedal. That's a mistake. Place only toe or ball of your foot on the forward motion with your heel on the matte. Rat...
PS. GST and shuttle shift are also great choices. The days of full manual are over for me. I have a full manual transmission with my International 454. While it's still a great tractor, using shuttle or HST makes me appreciate what the engineers have done.
