My 11 yr old son mows the yard (but not edging or trimming, not tall enough for our trimmer), he splits dishes and laundry duty with his 14 yr old sister. They both wash and vacuum the cars. He is responsible for the recycle bin (empties inside one to outside, and brings it to the curb weekly), his sister does the regular garbage in the kitchen. They both also do cleaning inside the house as well.
This weekend I trimmed all the shrubs (some type of holly with [censored] leaves), he loaded it all into the trash can then into the back of my truck.
They both do get an allowance, $5/week (I may up it to $10 soon), but they don't see a dime of it. It goes into a savings account they get access to when they go to school (if they don't go to school, I get to go on a cruise).
The next oil change I do, my son is doing. He has watched me several times, doing parts of it, but not all from beginning to end. My daughter has done oil changes in the past.
Both my kids help when I work on vehicles and have a basic understanding of what to check and when to check/change it. Both of them can change a tire (although my son struggles, he is small for his age).
My kids do have a cell phone (my son an iPhone 5s, daughter an iPhone 6) but they saved money for over a year and bought it used themselves. The phone plan I do pay for, $3/month for 30 minutes of talk time, so I can call them or they can call me in emergencies.
As a kid, I also had to do yard work, dishes, laundry, cleaning the bathroom etc. I hated doing it, but if I wanted to go out and play, I had to do it.
