Does it matter how you set your wheeled cart at the curb?
Simply put: no, but thanks for asking!
Whether you set your cart at the curb with the handle facing the street, the handle facing your house, or even sideways ~ the cart orientation doesn't matter for our crews. Ours is a semi-automated system: the carts are manually wheeled to the truck, and then a lift on the truck tips the cart contents into the truck. The cart is then wheeled back to the curb.
If the lifting were fully automated, then the placement would be very important: the lift bar on the front of the carts has to face the street so that the lift arm can hook onto it.
