I see three things you could have done.
1. Bent the shaft
2. Bent the stump jumper
3. Misaligned the gear box by bending/cracking the deck/gear box mount, elongated/enlarged gear box mounting bolt holes.

With cases 1 & 2, you will see a "wobble" as the stump jumper rotates. To determine whether it is the shaft or the stump jumper you may have to remove the stump jumper so you can measure radial end play on the shaft. Either of these problems can cause vibration. If the vibration is intense enough, you can cause further damage to the brushhog and possibly the pto shaft, pto and other tractor drive train components. If things break loose, you are a potential emergency room visitor (or worse).

In case 3, the stump jumper will not "wobble" as it rotates. The high point will stay in the same place in relation to the deck. If the deck/gear box mount is bent, there may be cracks or broken parts that need attention. The cracks or broken parts may allow movement of the gear box during operation. Elongated/enlarged bolt holes can also allow movement of the gear box during operation. Gear box movement during operation can cause vibration, increasing damage as you continue to use the brushhog. And again you can cause damage to the pto shaft, pto, and other tractor drive train components.

Take the time to find out just what is damaged and take care of it.

Farming has the second highest fatality rate of any industry in the country. Only mining is worse. Continuing to use unsafe equipment will help us beat miners in fatalities.
