Drill the pin hole 21. 22 is a retaining pin.

Although not shown, the pressure oil generator of the tractor A, the opening/closing cylinder 4, the lift cylinder 10, and the dump cylinder 12 are connected through hydraulic circuits each having a switching valve interposed therein.

Next, its effect will be explained.

When the opening/closing cylinder 4 is extended, the tine holders 2, 2 each rotate outward about the pin 3, and the distance between the hawk tines 5, 5 becomes wider. on the other hand,
When the opening/closing cylinder 4 is shortened, the distance between the hawk tines 5, 5 becomes narrower, operating in the opposite manner to the above.

Therefore, when transporting the bale D using the Hawk tines 5, 5, while the Hawk tines 5 are still attached to the tine holders 2, 2 of the cargo handling machine E, the Hawk tines 5 on both sides are moved in the same manner as before. pierce the bale D, or operate the opening/closing cylinder 4 and use the hawk tines 5 on both sides to remove the bale D.
After pinching, the lift cylinder 10 is extended, and the front loader B lifts the bale D via the cargo handling machine, and the tractor A runs to transport it.

On the other hand, when loosening the bale D, the main pipe 7 is fitted to the hawk tines 5 on both sides as shown in FIG. Fixing pins 22 are inserted into the pin holes 21 and 15 of the arm rods 20 on both sides and the tine holder 2, and the main pipe 7 is attached to the tine holder 2 to constitute a cargo handling machine E for dismantling bales.
