I started mowing my parents lawns, and my grandparents. Thats when i was only 7 years old, and had an old craftsmen. Now, im 14 and have over 25 customers in my neighborhood only. Not including the ones i have that my dad drives my too. I was 12 when i thought i should start a lawn care buisness. Now that i have experience the cost of the equipment i should tell most kids my age, have at least!, 700$$$ saved up. I currently have 1 dixon 48" ZTR, 2 Toro 36" walkbehinds, 2 echo trimmers, 2 echo backpack blowers, and a 8x14' trailer. Last year i made over 15,000$$ just from mowing lawns. Right now i have nearly 40,000$$$ saved! I suggest you look into all of this before hand and not during, I found out the hard way.
