Can the traction booster be adjusted to help on a Series One D17 when pulling a disc connected only to the drawbar?

Interesting that the traction booster spring needs to be compressed to trigger the traction booster. When does one think that happens, when the tractor looses traction and needs more weight? Is the slipping wheel able to compress the spring? No, this is not correct. The traction booster is activated when the tractor is under a heavy pulling load, to lessen the load. So that the wheels do not slip. Period.

Though the traction booster can be used that way it is not supposed to be. It is meant to transfer weight for traction so the tractor can pull a greater load not to lessen the load.

Reguardless you are not using the TB the way it was designed if you don't have the TB drawbar on your disc. Can't really call it discing if your disc is out of the ground half the time.........better to weight the tractor down and turn off the TB.

Eldon, nobody ever said the disc was out of the ground any of the time. All that was meant was that the traction booster provided just enough lift on the drawn implement to allow the tractor to be able to pull it under varrying conditions.

What about that is so difficult to understand? I put many hours on that D17 pulling drawn implements and used the traction booster all the time. It was not an issue of not having enough traction, it was more an issue of having enough power. The traction booster allowed the tractor to see a relatively constant load. Had the traction booster not been used, I as the operator, would have had to manually lift the drawn implement a little in order to be able to pull it going uphill.

The traction booster worked beautifully with the drawn implement could not have asked for more.

D17 you asked the readers a question that you obviously know (or think you know) the answer too.....why then did you even ask? If it works for you go for it!

The fact is that you are not using the tb as it was intended. You are using it as a neat way to decrease the load on the tractor by lifting the implement...nothing wrong with that. The disc will lift completely out of the ground on a hill...it happened to me when I tried to use a WD45 without a transport valve. Why do you think AC engineers developed that neat little valve? Precisely!!

Once more....the tb is designed to increase traction to the tractor by transfering weight to the rear wheels and you are not transferring weight. Why can't you understand that simple concept?

If the tractor doesn't have a transport valve (or if it is in the off position) and you adjust the traction booster lever up to a certain point the hydraulic oil will be pumped to the cylinder on the disc (after the lift arms have reached the full up position). This will make it pull easier, (because the disc isn't in the ground as far) but will not give your tractor more traction as no weight has been transfered to the tractor. If you are pulling up a tough hill the disc will probably be lifted out of the ground. Lower the TB lever if this happens and it should drop back down.

Hi, D17. There is a school of thought DownUnder in Australia that, up to a certain point -- around 250 hp, really wide single tyres are better than duals. The pluses seem to be that you can fill them with water or whatever other ballast you might favour where filling outer duals can be a recipe for disaster, you don't have the breakages sometimes associated with duals, you don't have a gap to fill with mud and/or debris and the tractor turns easier because it doesn't have the drag between the individual tyres of each dual wheel. One Australian manufacturer built 2w.d. tractors up to 350 hp on wide singles that consistently outpulled 4 w.d. tractors of similar hp. (See link below.)
Also, when using a one-way disc plow as I understand they are called in the U.S., 'setting' the plow correctly can do a bit to reduce the load too. Using a SWINGING drawbar, set the plow so that it does not cause the tractor to pull one way or the other but pulls in a straight line. This is done by altering the pulling position of the plow's drawbar on the draught bar and adjusting the steering link to suit.
One tandem one-way disc plow arrangement that found a lot of favour in Australia was to fit a drawbar to the rear of the front plow and simply couple the rear plow to that drawbar. Plows connected in tandem this way seemed to pull lighter than plows connected to a tandem draught beam. It was sometimes necessary to lengthen the draught bar on the front plow to get the centre of pull far enough over to balance the weight of the rear plow. The couple of times I set plows up like this, I also found it helped to have a 'rack' of about a dozen holes in the drawbar fitted to the rear of the front plow to allow for a bit of fine-tuning there too.
One of these set-ups that I made using 2 14 disc plows, I was pulling behind an old 2T series Cat. D4 of 36 hp. In one field, there was a creek about 30 yards wide with between 6" and a foot of washed sand in the bed. With no power lift on the plows, come to that creek with the D4, simply change down ONE gear and keep going. This farmer also had an 80hp Ford diesel conversion in an Australian-built Chamberlain 40K that had also been fitted with duals. In spite of the extra 44 hp, when I came to the same creek while pulling that tandem plow set-up with the Ford conversion, I had to get off and lift both plows out of the ground, get the tractor onto firm ground on the other side of the creek and lower both plows back in again. I liked that little old D4.
The Chamberlain tractor mentioned above originally had a 40 hp, 2 cyl., horizontally opposed, gas/kero engine that had NO water pump but was cooled by thermo-syphon water circulation. I drove a few and NEVER had one overheat on me. This same design was also modified into a 55 hp diesl engine in later models.

Happy plowing.

You have a wonderful day. Best wishes. Deas Plant.

how do you fill water ballast tyres?

Mark - You use a special adaptor that allows water in through the valve stem, at the same time as it allows the air to escape ... there are numerous types; here is one ...

traction booster works through the LIFT arms. AC did make a pull-type disc with the Snap-Coupler tongue, but it also used the lift arms, thus could gain some traction through the weight transfer system.

For drawbar drawn equipment, get a set of duals...!!! The WD-45 has too much power in loose ground, for the 13x28" tires...and needs the duals...!! Compaction is almost non-existent with them, and you will get over nearly every wet spot, without leaving any ruts.!!! I use the same size tires on the dual wheels...
And, since I use a 4 bottom plow, I use one on the left side, to increase traction... Ofcourse, I have the 4 tractor wheels Loaded, too...But NOT the duals....!!

If it is the same set up as a WD then the answer is no. The traction boost feature is simply a way to transfer some of the weight or load from the snap coupler mounted implement to the rear wheels. It is at it's very best with a snap coupler mounted plow. Again, I am not familiar with the D17.

Dave you are correct the traction booster was basically set up for the equipment that hooked to the snap coupler. It would like you said transfer the weight to the tractor its best use was with the plow where most of your hard pulling is done.

Today's Featured Article - George's Fordson Major - by Anthony West (UK). This is a bit of a technical info to add on to the article about George's Major in the "A Towny Goes Plowing" article. George bought his Major from a an implement sale about 18 years ago for 200.00. There is no known history regarding its origins or what service it had done, but the following work was undertaken by Harold alone to bring it up to show standard. From the engine number, it was found that the major was produced late 19 ... [Read Article]
