Figure 149.—Double Harpoon Hayfork. This is a large size fork with extra long legs. For handling long hay that hangs together well this fork is a great success. It may be handled as quickly as a smaller fork and it carries a heavy load.
Figure 150.—Six-Tined Grapple Hayfork. It is balanced to hang as shown in the drawing when empty. It sinks into the hay easily and dumps quickly when the clutch is released.
WESTERN HAY DERRICKS
Two derricks for stacking hay, that are used extensively in the alfalfa districts of Idaho, are shown in the illustration, [Figure 151]. The derrick to the left is made with a square base of timbers which supports an upright mast and a horizontal boom. The timber base is sixteen feet square, made of five sticks of timber, each piece being 8 x 8 inches square by 16 feet in length. Two of the timbers rest flat on the ground and are rounded up at the ends to facilitate moving the derrick across the stubble ground or along the road to the next hayfield. These sleigh runner timbers are notched on the upper side near each end and at the middle to receive the three cross timbers. The cross timbers also are notched or recessed about a half inch deep to make a sort of double mortise. The timbers are bound together at the intersections by iron U-clamps that pass around both timbers and fasten through a flat iron plate on top of the upper timbers. These flat plates or bars have holes near the ends and the threaded ends of the U-irons pass through these holes and the nuts are screwed down tight. The sleigh runner timbers are recessed diagonally across the bottom to fit the round U-irons which are let into the bottoms of the timbers just enough to prevent scraping the earth when the derrick is being moved. These iron U-clamp fasteners are much stronger and better than bolts through the timbers.
