If the job demands being "in mud", having chains does help. If your running a skidder and it is soft, you run chains. As for repairing them 10 times a day, you should buy better chains and fit them better.
I have been fortunate that I haven't had to do that in excess of 40 years ago, with 100+ hp in 2wd farm tractor in muddy fields trying to harvest corn with heavy double ring chains digging and chewing grabbing ahold of rocks they would break and it didn't matter how they where fitted. When forage for dairy cows had to be harvested or you wouldn't have an income you did what needed to be done, when it was needed. And forty years ago you didn't see the big welded ring chains on skidders, when those boys worked rocky ledgey woods they had to repair chains frequently also.
We are fortunate that now days it's 200 hp plus with 4wd and diff locks, but when a steep field gets greasy it can still be a handful. I chopped enough this morning for green chop feed and one load to freshen up an ag bag and the fields that we have left are slick enough I had to dead head all the way around and back and only chop on the down grade. We don't like rutting up or compacting our field as we try to do mostly no-till as it saves soil erosion, soil nutrients, fuel, time and labor costs.
The big boys are out chopping today all they can, and they are having to chop into dump carts, then run the dump cart over to there trucks, sothey have that 600 HP chopper, a 300+ HP 8 wheeled tractor hauling around a dump cart to fill the trucks, instead of the truck running along side the chopper so they are down to 1/2 the efficiency they normally have.
And as far as buying better chains, I am fortunate enough to be able to buy the good European style studded chains for my tractors for snow and ice. But, I know that when they get some age on them they will require repairs and that is always at the worst of times, now you are more then welcome to buy me a few spare sets so I don't have to repair mine, 18.4-30's, 16.9-28s, 18.4-38's 20.4-38's and 42's anytime.
