As John Mc suggested that Norwegian had the best method.
I had cut and paste these suggestions into my draft folder:
"There is a lot easyer way to put any style chain on than the way you did it. Try it this way. Lay the chain out behind the tractor the way it will lay on the tire. Take a piece of 1/4" rope about 6 feet long and at the first cross link tie one end of the rope to the center of the first cross link. Then tie a big enough loop to fit over the tire tread and loop it over. Then drive the tractor forward and it will pull the chain right onto the tire. Just be sure to check that the chain is maintaining its pattern when it goes up and over the tire. I am in my mid 60's and if I had to manhandle mine they would never get put on.
I found a very easy way to install the chains from reading different ideas here on TBN. First layout the chain with the outside UP. Then hook a logging chain on and back the tractor up to the tire chain. Run the logging chain over the tire and start it underneath. Then drive slowly ahead and the tire chain will be pulled up over the tire by the logging chain. Watch the chain to keep it centered and when the end clears the bottom it is super easy to hookup because it is pulled so tight.
I can put on a chain with springs and all in five minutes each.
I just put chains on my TC40DA yesterday. We got a few inches of snow last night - the first of the winter. I posted my purchase last year, along with the pain of getting them on. Someone here suggested laying the chains out behind the tractor, but using a bungy cord/rubber strap through a wheel slot to hold one end of the chain against the tire. Just drive forward. It worked like a charm and I did both wheels at the same time. The hardest part was laying the chain out. This method is so easy, I won't be concerned about leaving them off till I need them next winter"
