Wagon Features 4-Wheel Steering
First on the market with four-wheel steering for farm trailers is the True-Trak Co., Grafton, Wis.
    This is the new-style wagon we told you about in the Charter Issue of FARM SHOW. However, there was a mistake in the price. It’s not nearly as expensive as the first report mistakenly told you.
    The 10-ton wagon gear, factory equipped with four-wheel steering, retails for $1,250. “That’s about $200 higher than you’d pay for a comparable trailer with conventional two-wheel steering,” says William Wolf, inventor and manufacturer. Factory equipped True-Trak wagons with 6 and 8 ton capacity are also available.
    “The big problem with conventional running gears has always been that the rear end overturns,” explains Wolf. To solve the problem, he used two front ends and a “rack and pinion” mechanism to provide four-wheel steering. The “rack” or “T” turning mechanism activates all wheels, both front and back. When the front wheels are turned, the reach also turns, causing the back wheels to turn the exact same amount so they follow the tracks made by the front wheels.
    If you’re handy with a welder and can round up two front ends, you could buy the True-Trak “rack and pinion” mechanism and build your own four-wheel steer trailer.
