I need to replace one of the rears on my tractor probably both. What are the advantages and disadvantages of 23 deg bars and 45 deg bars.

Thanks, guys. I have a 130 w/ a 1000 loader and 4 wheel weights on the rear wheels. I currently have Armstrong Hi Power Lug 6 ply rears. Tread is good but one is damaged and has been showing a belt for some time which is why replacement time is near. This tractor weighs a lot when the harrow or mower is on the back. Do I need 6 ply? I'd buy oneTitan Hi-Power to replace the bad one but it now only comes in 4 ply for the size I need.

If I remember correctly, the original Firestone ads, Firestone was first to introduce the 23 degree tread design as their "Field and Road" tires, stated much less tread wear while transporting on paved surfaces and equal traction in field conditions. All R-2 tires (rice & cane) are still produced with versions of the 45 degree lugs as they are designed to operate in wet conditions. As far as straight pull on hard dry ground, radial 23 degree pull more than bias 23 degree but they have much more sidewall flex. I wouldn't put radials on a letter series tractor, regardless if you go 23 or 45 degree, because these tractors don't have the horsepower to utilize the slight traction increaase you would get in certain conditions and they definitely would not look right. Just my 2 cents worth.

The 23 degree tread was brought out becase it has longer life on pavement. The 45 degree will clean itself better in wet conditions. As far as traction in dry conditions, they are probably about equal. The 45 degree looks original if you are restoring to original look.

The only reason you would use 45 degree tires is if you want to keep an original appearance to your tractor. The newer 23 degree tires must be superior in traction or they would not be the only type offered on new tractors.
Please, replace both rear tires on your tractor, it will perform better, is better for the tractor, and just plain looks better.

Rusty: Here is what I have noticed over the years; 23 degree will give superior traction on reasonably hard surfaces. I have 23 on my SA and 45 on 130 and 140. On loose soil and side hill doing row crop cultivation the 45 don't slide sideways as much as the 23 do. I found much the same a few years back with 560 and 656, both close in weight and hp. On a outright hard pull the 23 would out pull the 45 on most surfaces. Again where side draft was a problem the 45 I liked much better. I had 23 on my 1066 and with duals the side draft item didn't seem to be affected in that application. I will admit I never had anything to compare with 1066. That side slip is quite noticable with the 23 degree tire on jobs like row cultivation, plowing, forage harvester, haybine, baler, etc. The only one that is a real problem is row cultivation with center and rear gangs. The tractor will start running like a dog on side hills and rear gangs tend to knock out some plants. Especially true in potatoes where you are trying to loosen a lot of soil for hilling. One thing I found surprising is H, 300 and 504 were not heavy enough for 2 row in potatoes. It needed the M, 400, 560 and 656, to get the volume of loose soil for good hilling thus stopping sunburn of potatoes.

Always felt the 23 deg had the adv in the straight pull and in most conditions, however on muddy conditions feeding cattle pulling a bunk feeder wagon the 45 deg seem to keep me from sliding side ways, esp if you are on a slight hillside. my opinion only cbl

Hi, my experience is the same, 23 will out pull 45 in most hard surfaces and last longer if driving on pavement.
Disadavantage of 23 is mud, will clogg easier, frozen ground or side hill will skid side ways very easy. If you are in a climate where tire chains are used, regular chains will fall between the lugs, must use Trygg chains.
Unless you are pulling with this tractor or doing a lot of pavement driving I would buy the 45 tires.
Many years ago when Firestone first came out with 23 degree tires, my dad had a JD 420U with loader on it. When he had to replace the back tires the Firestone salesman tried to convince him to buy both 23 tires. He was a person that did not like change so he bought one of each. Anytime he was using that tractor on slippery surfaces he was always cursing the 23 degree tire.
