Differences D8 35a and 36a

Same tractor 36A direct drive 35A tourqe converter 46A power shift

The 36 a was a 6 speed Direct drive D8H series. The 35a was a 3 speed Torque Converter D8H series. The 46 a was the Powershift model. I have operated all in Dozer and Pushcat configeration. My experience with the 35a was bulldozing over large trees for an Airstrip project and it was a dream machine to operate, just pull up to the tree, put the blade on the tree and open the decelerator, presto over the tree went. Nice for pushing scrapers out of the cut as we could double head and shift the lead pusher into 3rd then push the loaded scraper out of the cut at a faster rate of speed, not as efficient as the 46a but close. The 36 a was tough, shifting could be difficult until an operator learned the trackspeed related to the gear shifting then essentially, in pushing, could be shifted on the go to pick up the load on the scraper to be pushed. The 46 a was really good as it took the operators attention off shifting and onto the load etc. All were excellent machines, I operated them from Alaska, Cuba, Vietnam, Puerto Rico, South Dakota and I love the D8H tractors they were the best, rock solid and bullet proof.
