I work solo so the low handle holds the cart in a near vertical position while I wrestle the timber. When the weight of the timber comes down on the cart the handle comes up off the ground.

The design on the table calls for a reciever allowing the handle to be removed so it's completely out of the way when moving a timber. The handle will be curved and terminate in a T so one way up it's acting as your ground hold the other way up it's a convienant tow handle and gives you ground clearance while moving the timber. It could also act as another point of contact for your less than straight (crown up) timbers.

This flipping of the handle was my primary focus when it came to it's design, being able to feed it into either end of the reciever is just a bonus convienance since you can decide which way the cart will flop as you remove the timber.
