I would only run the chains when plowing snow to help keep the front end from being shoved over as snow builds in front of the front mount blade i use. Correct me if I'm wrong Hokie but isn't it OK to run chains on front as long as I have chains on back?
I am no "chain" expert - I like you, want to have the best traction I can in whatever I am doing, I live on a 2 acre piece of property that the only thing flat around here is the floors in the house!
I run around in four wheel drive almost all the time, but when I get near the road, I stop and switch to 2wd - no matter how careful one is about using 4WD, something has to "give"
For example - a story to explain what I am talking about, a friend of mine was telling me that his truck was making funny grinding noises in 4 WD while on the street, as I tried to listen to him, he mentioned that he got TWO new tires on the rear of his truck, then it dawned on me, the transmission is trying to fight to sets of wheels that have different diameters! Thus is was screeching while in 4WD, the different sizes cause a bind in the transfer case.......thus one set not rolling the same as the other.....
now getting back to the tractor, the tires when brand new have a turning ratio of something that the factory figures will work "good" for the ratio in the transmission.
Lets look at a hypothetical situation,
let's say the we have 24" tires on the rear and 12" tires on the front......( just for shheeets and giggles)
the 24" tire has a rolling circumference of about 75.4" .......the 12" tire has about circumference of about 37.7" - EXACTLY a two to one ratio.....makes sense too......
but - and here is where the pain starts .........
lets add a set of chains that stick up on the tires, o lets say 3/8" .......
now we have tires that are 24 3/4 and 12 3/4 in diameter.......
now doing the math....the RATIO HAS CHANGED!!!!! ok - by just a little bit, now it sits around 1.94 to 1 .......this is where the wear and tear happens!
that little .06 is going to cause something to bind! Now on snow and ice, the rubber tires will slip, rubber on snow/ice - something can give easily and all is forgotten, but - when those chains are placed on the both ends, they are "biting" much better than rubber.......so that wear is going to happen inside the axles, splines ....etc......
just my 2 cents.........
If only on snow and ice and for limited time........might be ok. But .....I would be careful and use only where it was absolutely necessary.
