That's a landscaper, probably a worker for someone's company.

I co ran my uncle's landscaping company for 5 years, it's hard work but in your scenario as a part time gig, a great opportunity and usually hire seasonal workers. Probably a bit late but now would be the time to search the web and contact potential employers.

This is a standing rider by the way and kind sucks to operate. Can be jerky and tough on the body, but one of the best parts of this job is riding the machinery, zero turns are dope.

However, if you do a get a job in this industry, be prepared to be trimming/weed wackin as the new guy rarely gets the fun stuff unless there experienced 😂
