Needed to replace the bent blades on my riding mower.
- Made the mower safe to work on the blades (remove spark plug wires, etc.)

- Raised the mower to get access to the blades, wedged a wood block against the blade.

- Used impact driver with socket to remove bolt holding blade.

- Removed blade, replaced with new, replaced bolt and tightened with impact driver, ..... and you know the rest.

The tie rod on my 20 year-old lawn tractor snapped.
I used two wrenches, unscrewed both ends of the old tie rod and it fell out. In nearly no time, I had the new one in. After finding the right end wrenches, I don't think I had more than 10 minutes into the project. Easiest repair I have done on anything in a long time!
