Probably like everyone else we are fighting mud. We break a lot of new land every yes'r dozing bush etc and that stuff has no bottom. This year I bought a few sets of 68/50.00 tires for the combines but they sent cutting it. Just curious about tracks or possibly a quad track tractor then swapping the tracks into combines in fall. We've never ran tracks and have always been worried about how they would stand up in stony ground. Some of it has a lot of footballs but in the breaking anything that's gone in a windrow and burnt then exploded throws out a million sharp shards. Tires seem to handle it fine just not sure if it got rattling around in the undercarriage in tracks how they'd stand up. Anyone have experience?
