Thanks, Don and Tracy. I've now read the manual as suggested - dumb me for not trying that first! And interesting that the manual says both tightened and loose are right, the answer depending on how the hydraulic pump controls are set.
That said, would you set the pump for weight transfer for participating in a tractor pull (clamp loose), or set it otherwise (clamp tight)? Or do the pump settings not matter for pulling a heavy draw bar load? It'd be great if TB worked at a tractor pull!! |
Lifting the arms up wouldn't do a damn thing, at a tractor pull... I watched an idiot hook to the sled with a d-17(4), with the hitch point being a 3 point hitch drawbar... A wild ride ensued as the TB kicked in, both the arms came up, then the front end, as the weight transferred to the rear. Damn meth head girl almost flipped the tractor...

talking about tractor pull' if you start the pull with the arm's down when you get done pulling the traction-booster' if it works will lift the arms all the way up 9 times out of 10 at the end of the track you will be putting them back down. the draw bar has to be working with the traction-boost or it would not lift the arms on it's own under a hard pull.stock draw-bar; same as the man has in the first picture.

Any tractor pull I have been in if the tractor is using a 3pt draw bar its has to have stabilizers to hold the arms and draw bar at a certain height. Usually at 20 inch maximum.

Can't remember whether it was an exhibition pull or what. Think it appeared in the stock antique class of the pull. I know the thieving, lying, meth head in question, and his loser GF... He aint been back, after that pull...

Traction booster does not work with the drawbar unless it is somehow connected to the hydraulic arms. I think some are confusing the tractors equipped with a spring on the snap coupler bell with traction booster. Not all AC tractors had the spring on the snap coupler bell. Actually most did not have the spring. Here are a couple pictures I found of traction booster drawbars. The snap coupler one is currently for sale on Ebay. Only with one of these hitches installed will the traction booster work, using a drawbar pulled implement, unless you are using an implement that is mounted to the hydraulic arms. Three point hitch traction booster drawbar  Snap coupler model (which I never knew existed before)

All Traction Booster systems had a "spring" of some kind in them. The snap-coupler design actually used a big coil spring. The 3-point hitches used what is called a "torsion bar" spring. it is a shaft that is anchored to the frame and gets twisted when under a pull allowing the lower draft arms to activate the linkage to the traction booster system. A-C never used the top link compression like little Fords do. They always used the pulling arms. That way pull-type implements could benefit from the weight transfer system.

[QUOTE=Dave(inMA)
I gotta say that the SC hitch system is great for mounting implements like a plow.......not so much fun for mounting the draw bar.  Anyone got a good system for mounting the draw bar that takes the sting out of lifting and engaging the bar into the bell?
Thanks for all the replies!
Used to lift now I balance the drawbar on my floorjack, roll it under, jack it to the right height and push! lots easier on my aching back HTH...Harvey

Whew! Interesting stories and information. But I am unclear about whether TB comes into play when pulling a load.
My tractor is equipped with the 'standard draw bar' shown on p27 of the Operator's Manual. The hydraulic lift arms are not used in this situation - the draw bar unit is locked in place - the ends of the draw bar arms hook on pins up under the tractor and the arms are pinned to the multi-hole plates which in turn are bolted to the tractor. With a load applied to the draw bar, it can slide in either direction (toward front/rear of tractor) as long as the clamp bolts are loose enough to allow this.
So....with a load (ex: weight sled) attached to the draw bar, I'm reading the posts and the manual to say that TB will come into play as long as the pump settings are correct and the draw bar can move back and forth. Is this correct? Also, the lift arms may raise or lower but this doesn't apply to or remove from the load any lifting force. Also correct?
Thanks very much! Dave

Here's what I use as a drawbar. It's my homemade SCcarryall with 2"
receiver. I use forklift forks for the carrying, slide a balless sleeve
in to use as a drawbar. I've got 3 real drawbars collecting dust around
here for the past 15 years sinc eI made this.

I never imagined that something that could have a "screw loose" aaaaaaa (bolt or two) could cause such an exciting post.

What kind of oil is best to dribble on the drawbar, sos it slides easily, while in traction booster mode, regular or synthetic??? |

Slight leak on pto seal or hyd outlet block usually dribbles down nicely on my drawbars . . . . As for handling the drawbar assy., picked up an aluminum bread cart some years back outside a curio shop I was driving by in South TX that had a bunch of restaurant equipment. Thought of it for moving stuff around the shop but soon realized the low height was perfect for install/removal as well as storing SC drawbars on D-Seiers. 12-14" 4x4 up frontputs drawbar eye at just the right height, also on the OEM 3-pt. adaptor. 20-24" 4x4 near the back of the cart supports either hitch for dropping/install and storage and 3-pt. adaptor arms fold down inward just right. Sure is a back saver and wheeled wherever you want it in the shop, can swap out hitches in just a couple minutes. I'm way past the age of "slinging" the SC hitches under tractors anymore.

This works better Harvey as you can slide it all four ways, forward, backward, right and left. https://www.allischalmers.com/forum/slinging-the-drawbar_topic56506.html

I'll keep my eyes open for used restaurant equipment! Sound like a great solution. So's the floor jack - in my case I was outside on gravel - next time I'll move her inside onto concrete.

Dave or anyone else interested, PM me and I can send a pic of the cart I use via e-mail. The wheels on the cart I have are large enough to use it outside also. Picking up a new battery at Wally World a while back and asked what they did with the used carts (both regular shopping, steel and aluminum stocking type) as seen some at rear of store near the automotive bays. Manager advised they were put out back until they had someone pick them up for repair if possible. If repair cost more than they deemed worth it, they scrapped em' and yes, they would let them go.
