Standing at the back of your tractor, in the center where the draw bar attaches down low, you can jack it up there. Then put your stands out near the axle hub for safety, but leave the jack in place in the center. Just let the jack down to the stands for stability. All three items remain in position and holding some weight.
Jacking up the tractor with the jack out to the hubs will not harm either!!
Hurting the tractor will be less likely then you getting hurt! It's a tough critter.
