Maybe this has been mentioned, but I think some people forget one very important fact. When your back wheels come off the ground, ALL of the weight on the back of the tractor, ALL of the weight on the front of the tractor, PLUS the load in or on your bucket, forks, ALL the weight is on the front wheels and tires. it exceeds the maximum weight the front axle and wheel tires by double or triple. Maybe more than that even. I know this because I do stupid things sometimes. Sometimes I get by with it. Sometimes it costs me..
