While at school learning how to operate a Bobcat, we did many other training sessions that involved our heavy equipment.  Such things as simple maintenance and care of the Bobcat was an essential component of the course.

One of the hardest parts of the course (for me at least), was to change the rubber track for Bobcat mini excavator.  It was not like it was hard or anything, but for whatever reason, I just had a lot of problems to get it to work properly.

It got to the point where I had to have separate instruction from my professor just to get me to figure it out.  After a lot of trial and error, I was eventually able to get things worked out.  I was able to barely pass the practical test on changing them, but I did finally make it out of school.

Honestly though, I still struggle each time that I have to change a rubber track - I just hope that someday I will figure it out.
