Tile plow-trencher lets you cut up to 6 ft. deep and hunt for existing tile.

For 10 years, inventor Sylvester (Junior) Liebrecht designed tile plows. But about every time he would sell one, he would find that the customer would come back in need of a trencher, too, to put in deep outlets and hunt for existing tile.

So a year ago Liebrecht came up with an idea to save his customers from having to buy two machines. Using his standard tile plow as a base, he added an auger that the driver could deploy in those situations where he or she needed to make a cut deeper than the 3_1/2- to 4-ft. cut made by conventional tile plows.

"We don't know what to call it yet," Liebrecht says. "But it is a plow with an auger trencher on it. And we have applied for a patent for it."

Trench on demand. The 20-in. auger made of heavy flighting is welded directly underneath the tile plow and held in place by bearings. You can use the auger to cut a trench up to 6 ft. deep without stopping the tractor or leaving the tractor seat.

"When you're plowing through the field and have a deep cut coming up, you can engage your tractor PTO, slow your ground speed and then engage the auger to the ground with the hydraulics from the tractor," Liebrecht explains.

In addition to performing the job of a trencher, the auger also makes the tile plow easier to pull without having to add horsepower. "If traction conditions are really bad, you can run the auger partway and take out 50 to 75% of dirt with the auger," Liebrecht says.

It also can make backfilling easier than if you were to use a conventional chain or wheel-type trencher. Rather than putting all of the dirt to one side of the trench, the auger puts 30% on one side and 70% on the other so the dirt is closer to the ditch. And it has fewer moving parts than conventional trenchers for less maintenance. "The only thing you have to maintain are the cutters," Liebrecht says.

Handles range of tile sizes. The combination tile plow-trencher can put in 4-in. standard lateral to 12-in. tile. It has all the features of Liebrecht's standard tile plow, including automatic grade control, automatic tilt, tube feeder and slope indicator. All it needs to operate is a 200-hp tractor with a creeper-drive transmission.

Liebrecht, who does drainage work on contract, used the unit all last summer. He successfully put in 250,000 ft. of tile, 25,000 ft. of which were trenched with the auger. "It has been a real handy machine," he says.

He is now in the process of building several units to market this spring. Already one has been sold to a farmer in Illinois. "More and more farmers are doing their own drainage work, so we're probably going to sell more to farmers than to contractors," he says.
