Keep in mind that the Hi/Lo in the 35 does not affect the PTO speed. You get 540 PTO operation in all six forward and two reverse gears. The Sherman hi/lo in the TO30 will change the PTO speed. The real advantage of the 35 for me is the low range which allows you to go slower that a TO30 and maintain the 540 PTO speed. Very useful for snow blowing and bush hogging rougher/unknown terrain when you want to be slow and careful.
