It's like a giant furniture mover's dolly for moving trees.
This method works great for trees that a vehicle can't get to.
When there's vehicle access the A-Frame method of tree moving
works great . Manual methods work okay for small trees. But I have ten biggish fruit trees to move with no vehicle access. New methods are needed.
This is big heavy stuff. It can fall and crush heads and bodies.
Ropes under tension can snap and fly a long way.
I've seen it happen. It can cause great damage to people and property.
I saw a broken rope fly through a car breaking back window and windshield. It sounded like a gun.
Don't hurt your back. Trees grow much faster than a back can heal.
