I do not know about the D17 but I think the traction boosters were all the same. I have extensive experiance with the WD's both before the snap couplers were avail and after we had snap couplers.

The WD traction boost does depend on the pull on the drawbar which is linked to the hydraulics and, as the pulling load on the drawbar increases, the hyd's put upward motion on the lift arms. This shifts some of the implement weight to the rear of the tractor boosting traction as long as the wheels do not slip.

I am sure that myself and others who pull from the drawbars with these tractors would like to see any way to get traction boost from only the drawbar!

Well, Dave, I wish I still had the tractor, I would show you. It worked and worked very well. After all, the early (Series I) D17 had such a simple hydraulic system, it didn`t care whether the oil went to the cylinder that raised the lift arms or to the remote outlet seeing as they were connected together. Under a hard pull, the drawbar compressed the snap coupler spring and if the traction booster was adjusted right, the result was increased oil flow to the remote outlet that effectively raised the harrogator. Nothing was attached to the lift arms and the engine load was constant, uphill or down. The traction booster effectively put more of the harrogator`s weight on it`s own wheels.

It worked like a champ.

We used to do that with a pull type field cultivator. The Traction Booster system is actualy an improvment on the original Ferguson draft control devise. The A-C snap-coupler plows used the natural line of draft to maintain depth and you had to overcome the plow suction to lift the plow out of the ground. By using the draft sencing hitch they found that they could load the rear wheels and maintain plow depth and somebody coined the name Traction Booster. In the old WD manuals they simply called it "drawbar control". Works very well too. The weight transfer deal was adapted to other implements in various ways with special hitches but like you said you could use it just like draft control with pull type equipment. Transfers no weight but will lift to keep draft more or less equal. Can't do that with anybody elses system unless a person used the draw bar that attached to the 3-point lift arms.

Today's Featured Article - A City Guy's First Tractor - by Fred Hambrecht. After living in apartments in Atlanta for more years than I care to remember, the wife and I decided to move to the country. Humming "Green Acres is the place for me..." we purchased a 29 acre tract about 60 miles south of Atlanta. Next came the house, I could talk about that ordeal for another two weeks... But, I want to talk about my tractor! We didn't even own a lawnmower, and all of a sudden we had enough grass to feed all the starving children of the bovine world. Naturally, I talked ...
