patrick_g said:if it bogs down you can give it more throttle but that isn't a great solution since more throttle moves the tractor through the grass faster which increases HP requirement and you stay just about as bogged. You can shift down but then in maybe 10 ft you may want/need to shift back to original gear. Shifting over and over is not convenient.

Actually.. that's not 100% correct... If you are mowing and hit a tough patch, and your machine bogs down, then your engine speed drops, thus your ground speed drops.. if you compensate by adding throttle, you are merely powering back up to rated pto speed, and thus that normal ground speed. You cannot be bogged down in engine rpm, AND have a higher ground speed.. both conditions would be mutually exclusive, since engine rpm and ground speed will be ratio locked mechanically.. thus if you can add throttle to maintain engine rpm, then your ground speed will not change.
Alternately, you can take less of a bite in that area. At that point you get into a travel speed vs width of cut issue. is it better to cut a wide path very slowly, or cut a narower path faster. in many cases, cutting the slightly narrower path faster, is the better option. I've seen it on mowing and plowing rigs where you have tractors that are just powerfull enough to pull 'x' bottoms or width of mower, in their lowest gear.. or they can drop a bottom or a size class of mower and make a better forward speed. Typically this results in lower fuel usage and work that is finished a tad faster.. IE.. why pull 3 bottoms in max rpm and 1st gear when you can pull 2 bottoms in 3rd gear at rated rpm.. etc.
Not saying the HST isn't good for any of this.. just saying the gear tractor isn't as clunky as it is made out to be. Reminds me of those 'as seen on tv' comercials.. where they show a person clumsilly cutting up food with a regular knife.. banging around wildley and making a mess.. but then out comes the new 'super-cutter' and then the person makes gracefull cuts.. etc... IE.. there is a little embellishment taking place there..
