Looking for mowers for students(broken, unwanted) - $50

I'm looking for lawn mowers for students to work on.
Broken, not starting, unwanted, anything to help them learn.
Depending on what you have I can offer a few dollars for it, it may at least be good for parts to help offset some repair costs.
You're welcome to drop off anytime or I can pick them up in about a week.
No rush, no commitment, just looking for what you no longer want.
Maybe I can put it to good use.
Please message me if you or a friend/family member has something laying around.
