Chains: Front or Back

[OrangeAgain]

I have front and back chains for my 70HP tractor, but am thinking of only putting them on either the front or back. Which is better? Why?

This topic has been beaten to death very recently. Time to do a simple search.

Chains on front or rear tractor tires for pushing snow

Just this weekend cut down some old tire chains for the front of the B26.

Pretty smooth on gravel.
Fronts are easy to put on.
Don’t get much snow here and when we do paralyzes the city. Freeze/thaw/freeze makes for a lot of ice. Sometimes have to scarify thru the ice to expose a little gravel. Tire chains do that on their own sometimes. Or wait a week and it will rain.

I don't know anything about your tractor other than it has 70 hp., but when I put a set of 15" chains on the front of our John Deere 530 they didn't seem to help much at all in the snow.

Look at the size of your front differential, then look at the size of that on the rear. Then ask yourself which will take more stress.
For the best traction of course, put them on all four wheels.

I had HD V-bar tractor chains for my Ford 1700. Front and rear. The Ford was 4WD. If I had to go with only one set - go with the rear. More weight - better traction.

Not sure I'd want to chain all 4 wheels on a 4WD. Traction is awesome if you do, and I did it myself for years - but use caution when the traction gets too good. There is a real mechanical danger of breaking something in the drive train. Tractors need tire slippage in 4wd to protect the drive train. If it is hard to shift back OUT of 4wd then there is too much "windup" in the drive train. Windup means eventual breakage.

If the tires cannot slip - as in AWD cars - then to protect the drivetrand and maintain steering a center differential is required between front and rear axles.
No tractor I'm aware of has that center differential. Possible Fendt or some European models do...

I agree with this statement. "Four wheel drive " tractors are really front wheel assist. And with the front lead design built into them they are always slipping a little on turf. Anything restricting this slippage will stress the front drive train, such as driving in fwd on pavement. Aggressive front chains can do the same.
When I was buying aggressive studded chains a number of years ago my dealer strongly advised against putting them on the front for this reason. They had seen a number of customers damage their tractors this way.
I manage just fine with just rears. Plowing snow, logging etc.
I know many have them both front and rear and have had no problem. But for me I am heeding the advice of the dealer .

I understand your point but to think chain on ice/gravel or even asphalt would get traction to the point of drive train failure is comical ... 4 wheel drive on bare asphalt that I can see but if you want to reduce traction on bare asphalt chain would accomplish that.
