Hey man i just turned 21 as well. I have been landscaping since i was 14 and owned my business since 16. I dont cut grass so I have no mower but i own 2 dump trailer , dodge ram 1500, debris trailer, and a ton of trimmers chain saws and hand tools. I also own a jetski LOL 04 gp1300r and it gets alot of use cause im here in tampa, fl.
Any tips for me you seem to be ahead of the game and expecially for a 21 year old!.
Keep it up man
