Nice place you have there...we ended up doing a huge water feature in the backyard...and doing hardscape. Which...took up much of our lawn. (Which I think was my husbands plan since we have community association property right off our drive. That...someone else mows.)
You have a couple decent japanese maples in the ground. Is the green tree in background in pic 3 of third set a japanese maple? Okoshino?
Good work. Are they difficult to grow there? They need pampering in texas.
And congrats on tractor.
It looks like it has dissected leaves but it's not mounding mushroom shaped so my best guess is Acer palmatum 'seiryu'.
Now you need to enter a loan-mower race and plant the loan with prebonsai...
