Attempt Mechanical Separation with Heavy Machinery

What happens here

The project begins with a man presenting two plastic 5-gallon buckets that have been stuck together for a year. He expresses the desire to separate them due to the rising cost of buckets. To attempt separation, a heavy-duty chain is attached to the top bucket's handle and another chain to the bottom bucket. The chains are then hooked to two different pieces of heavy machinery: a compact track loader (skid steer) and a mini excavator. Both machines simultaneously pull in opposite directions to try and force the buckets apart. This attempt fails, with the buckets remaining stuck.

Goal: Pull the stuck buckets apart using opposing force from two machines
