Abstract
A hydraulically tilting dual bale spear having multiple bale tines is presented. The bale spear has a first frame and a second frame connected to one another at a pivot point. A hydraulic cylinder is positioned between the first frame member and the second frame member. When activated, the hydraulic cylinder tilts the second frame with respect to the first frame member thereby providing a safer, faster and more efficient way to gather and pick up bales. The benefit over a non-tilting dual bale spear is that it allows the operator to pick up two bales without stopping or dragging the first bale across the ground and ripping the net wrap. It also allows the operator to level out the two bales once picked up for easier off load onto a truck or trailer.
