 Topic: Traction Booster

I have a d15 series II and I have never done much plowing at all and I was wandering if someone could help with explaining about the lift/lower lever and the TB lever and the operation behind them? Thank you

The Traction Booster segment of this video describes the concept as well as anything I have seen: http://www.youtube.com/watch?v=cYH3q9nJ-fc
The D15 does the same thing, although it has a separate lever for the traction booster adjustment. The separate lever allows you to set the TB and forget it, unlike the single lever system as used on the WD, WD45, CA, and early D10/D12 tractors which requires adjustment each time the implement is lifted and lowered (and requires another adjustment for lift/hold and drawbar control as well). In the field, it really works very well, and it makes it possible to do much more work with a lighter tractor that uses less fuel and creates fewer soil compaction problems.

Thank you for that help. Would there be anyone with some more in depth info? such as do you put lift lever in lower position in quadrant hole or what? I know all this sounds dumb but aint done nothing but cut , rake , and baled hay for ever..thank you

Jon, you are correct in your assertion as to where the lift-lower lever should be when traction booster is needed. If it will stay in the hole-that is good. If it is higher up(hold position) the traction booster will only raise but not lower the implement when not needed.
Move traction booster lever up to get some lift, soon you will get the "feel" and put in a slot, as normal operation is just a slight lift, ready for a good hard pull to put more lift, thus transfer of weight to the rear wheels.
When new these levers would stay in the hole until moved.

The operator's manual for the tractor is the best source of this kind of information, and it would be a good idea to own a copy. I don't see one in the "Allis Store" at the top of this page, but you might find one at some of the vendors who support this site. Click on "Parts Etc" at the top of this page for a list of vendors. In reference to your last question, I can tell you that in order for the Traction Booster to operate correctly the lift/lower lever must be latched in the "lower" position, otherwise the implement will rise out of the ground and stay there as soon as it encounters any resistance.

For the WD/WD45, Allis made a small quadrant stop so you could raise the implement, then lower your lever to the predetermined stop each time. It is shown in the parts book, but they are hard to come by.

I inherited Allis Chalmers d15. I am in the process of trying to bring it back to original condition. Where the line from the traction boost gauge attaches to a block which has a pipe going down into the case and one going over the side into the case the line is broke can I get parts to replace that if so where

There’s a couple old A-C sales films on YouTube that do a very good job explaining the traction booster operation and how to run the tractor with it. The thumbnail sketch is start with the lift lower and traction levers down. When you start to spin lift the toothed traction lever a notch or two until you stop spinning the tires. Plow setup takes some trial and error and being able to recognize worn out points. Getting copies of the owners manual for the tractor and plow will help quite a bit. Also try to find local tractor clubs having a plow day. There’s usually at least one person that will help you figure it out.

Last fall, plowing that very tough 7 yr wet alfalfa sod, I never would have pulled that 4 x 14's mounted with my D-17 XT. Not a worst idea. Has to be adjusted correctly and used correctly and if that doesn't work, quit bitching abut it and hang wheel weights on the tractor until you're happy.

Only if someone refuses to understand how it operates and how to correctly adjust it. When properly adjusted, the Traction-Booster system will allow a smaller tractor to do a bigger job than the systems other manufactures used. The "set it and forget it" adage works wonderfully if it's set right. Just watch videos of early Fords where the operator constantly has his hand on the lift lever. In today's world too many have gotten used to having a tractor much larger than needed and also having it weighted down much heavier than necessary causing compaction problems unheard of in the days of smaller tractors.

If it was fun to pull in LOW gear, I could have a John Deere.
Real pullers don't have speed limits.

Traction boost parts I am trying to restore my father's old D15 Allis chalmers. The 1/8 inch line that runs from the traction gauge to the small square block is bad I need to replace the line also the block that it attaches to might have to be replaced. I have an owner's manual and a repair manual but I cannot find those particular parts. Where would I go to order those parts. parts.

My dad bought a D-17 over a comparable John Deere. The two dealers brought out tractors and plows. The AC walked away from the JD. The difference was the traction booster. Well thought out controls and the pulling power of the D-17 were among the many advantages over the JD. I was just a little kid but I still remember seeing this demonstration at our farm. To this day, I feel the power director system employed by AC is a great feature.

Dale , I see what you're talking about . Might be able to repair that line with a compression coupling ? That's what I did on the one that runs from the base of the oil filter to the oil pressure gauge . NAPA fixed me up . Good Luck !
