706 Drawbar Height

It seems that my drawbar is much lower than what"s specified in my manual. It measures about 12", but the spec is 16". It has the stock tires (15.5 x 38) and I don"t see any way to adjust it. Any ideas?
 
Is there another set of holes where the horse shoe attaches at the axle housings?

May be able to raise it there.

Are your front tires oversized?

I'm not sure what you mean about the "horse shoe" attaching to the axle housing. There's a chance that the fronts are oversized since I haven't actually looked at them. I'll see.

This isn't my tractor, but this is pretty much what the drawbar looks like. It's the same model.

Okay I did not know it had a fast hich. So it has the telescoping drawbar.

The horseshoe hitch is attached to the axle when no 3pt or 2pt hitch were used.

Bout the only way to get a higher drawbar on the one you pictured is to put in the 2pt draw bar and set it to the height that you want with a hitch plate on it.

Koeppel: I've never seen a 706 with 15.5x38. In our area they all came with 16.9 or 18.4 x 38. Makes a huge difference in drawbar clearence and will give way better traction. That 15.5 is a lower than average profile

I went from 15.5 to 16.9 on my 560 and 656, mainly to get better drawbar clearence in the hay field. I also dropped the chloride at same time, yet those 16.9 gave better traction. Couldn't believe they were the same tractors.
 
706 drawbar is a fixed height. Can't be adjusted. It is what it is unless you get some taller tires.

16.9x38 is about the tallest I'd put on a 706, though. They will speed up the tractor a lot, and it won't seem to have nearly as much power. Truth is that the tractor has the same amount of power, it's just being soaked up by going faster. If you drop a gear, the tractor will be going the same speed as before with the smaller tires.
 
15.5 seems a bit too low profile for that tractor.
I have 2 706's myself and they run 16.9's on them I believe that is the stock size for that tractor,however I have seen some 706's with 18.4x38 rear tires on them.
 
Though not common I have seen probably at least a half dozen 706s on 15.5x38s. About 3 years ago we bid on a 706 German D that had 15.5x38s. Most common tire size in this area on the 706s were 16.9x34s. My son bought a 706 German D this summer that has 18.4x38s on it. That is the only 706 that I have seen with the 18.4 x 38s. Front tires are 7.50 x 18s or 20s. Tractor really sets up off the ground.
 
<a href="http://www.external_link/td/004/td4669.html" target="_blank">external_link</a>, as well as my owner's manual only state 15.5x38 for rear tire size.

Tires:
Ag front: 6.50-16
Ag rear: 15.5-38

Can I put 16.9x38's on the same rims?
 
Koeppel: Tractor Data doesn't know diddley squat. I've never seen a book with so many mistakes. I'm sure if I took some time to dig through some old IH literature I could find a number of options for a 706 including 15.5x38, 16.9x38, 16.9x34 and 18.4x34. The tire will tell you how wide the rim should be.

Personally I can tell you, 15.5x38 wasn't worth a tinker's damn on a 560 or 656. It would be next to useless on that heavier chassis of the 706. If it were me 560 and 656 get 16.9x38 and a 706 would get 18.4x38. Larger than 706 would get 20.8x38 and some of the big ones over 100hp full time duals.
 
You can put 16.9x38 on those rims no problem. Worst case the rims might be an inch narrower than the tires specify, but IIRC, the 15.5x38 and 16.9x38 use the same width rim.
 
Well, regardless of what TractorData knows, my IH owner's manual also says that the stock tires were 15.5x38.

Anyway, Would an 18.4x38 fit on the rims that I have on it now or will I need new wheels to upsize the tires?
 
Koepell: Every tractor tire has labelling on it telling you the proper width of rim to use. That is the rim that will give the very best traction for that particular size tire. You can vary by a inch or so, without much problem. Anymore than that a traction will suffer greatly.
