I put a front blade on my Farmall 340 tractor with a loader. It works okay pushing snow when I leave the land plane on the rear for weight. I checked in to tire chains and for 13.6 x 36 tires they run from $600 plus tax for simple ladder chains to over $1,000 for the more sophisiticated chains. I clear about 3/8 mile of road that is hilly. I wonder if something would work for the occasion slick spots like emergency automobile chains. That is, just four to six links of chains across the tires and held on by bunge cords. Seems like it would be cheaper and easier to install than a full set up tire chains---but of course, not as effective,---if they would work at all. Any one have any experience with frabricating and using something like this on a tractor? I have chains on my ATV and they work great. I also have a 420 John Deere crawler I can use if snow is really bad, but the blade is not as wide as the 340 blade. So, I am looking for something that is a cheap alternative for occasional use. Thanks in advance
