New Lifting Legs For Dump Trailers
This "Load-Lifting" idea, born in a Finnish farmer's workshop, makes it easy to gravity load seed and fertilizer directly into planter or drill hoppers with a dump trailer.
Here, courtesy of the Finnish farm magazine Konevieste, is how the device, invented by farmer Reijo Raiski, of Alavude, works:
The lifting legs, one on each side, are made of heavy tubular steel beams. They're inserted manually into slots built into a support structure welded to the underside of the trailer. When not needed, the legs ride upward in an out-of-the-way transport position.
When needed to lift the rear end of the dump trailer high enough so seed and fertilizer gravity flows directly into the drill (or planter) hopper, the legs are manually removed from the "transport" position and inserted into the "lift position" slot, with the foot of each leg resting firmly on the ground. As the trailer is raised up, the legs act as a fulcrum to raise the rear end of the trailer rear wheels and all 5 ft. or more off the ground enough so seed and/or fertilizer will gravity feed directly into the drill hopper.
In the "lift" position, the legs are far enough apart to straddle drills up to about 10.ft. wide. Well-built trailers, with a sturdy undercarriage to support the loaded trailer, can be left upraised on the support legs and a tongue stand while the tractor is unhitched and driven off for use elsewhere.
