Farm drainage tile plow- First 3 minutes are the outlet prep- Tile plow installation starts at 3:00 - (Turn on "Closed Captioning" or click "Show More" which explains how it works)

I designed, built in my farm shop, and patented my original drainage tile plow concept in the mid 1990's. (US Patent number- 5,975,804)

Consider the increased grade control accuracy for a road grader (or land plane) compared to a less accurate 3 point hitch (or rear mounted) blade. That is what led to this drainage tile plow concept.

This newer prototype tile plow was designed and built in 2012. The curved cutting point design is a "very" significant improvement. This prototype tile plow weighs about twice as much compared to previous tile plows built similar to this. It was purposely "overbuilt" in order to withstand significant stresses. The extra weight also helps the grade control accuracy in very tough or rocky conditions.

This video shows some tools I made (in 1997) for easier hookups to an outlet, especially when working alone. The tile holders keep the tile in place without blinding with dirt, which is helpful in very dry and hard subsoil conditions. If desired, gravel or pea rock can be used to blind the tile "at the outlet" to prevent possible distortion of the tile.

The existing tile line (with the yellow stripe where the Tee was installed) was installed by my original tile plow several years before this new tile line was installed. Notice that older tile line had a nice round shape several years after it was installed.

Prior to operation of this tile plow concept, the pitch of the plow is adjusted to a desired level (or pitch) using a second tractor hydraulic outlet. The bottom of the boot should be adjusted parallel (or level) to a level surface, so it will form proper support for the newly installed tile. Once that pitch is set to the desired level, that second tractor hydraulic outlet is not used. (It is best to somehow lock out the control for that second tractor hydraulic outlet or separate it, so it is not confused with the first primary tractor outlet that controls grade.)

Grade control is done by using "only the first tractor hydraulic outlet". Staging cylinders keep the plow frame at the same pitch from the raised to the lowered position. Notice how the plow frame stays at the same pitch when it is lowered into the outlet hole starting at 3:00 minutes into this video.

The curved incline design on the cutting point pulls much easier than steeper straight inclines on other tile plow cutting points. It also creates less sidewall compaction adjacent to the newly installed tile, which increases initial water movement into the tile.

The subsoil was extremely dry and hard in this video, so it was significantly more difficult to dig with a backhoe or a shovel. But the tile plow still worked very well in these adverse conditions, mostly because of the curved cutting point design with a flatter angle of incline at the leading edge of the cutting point.

That flatter angle of the replaceable cutting point also significantly increases the length of use before wear can negatively affect the function of the plow, which is an issue with other plows with steeper angles of incline of their cutting points.

The JD tractor's GS2 auto steering system was used to drive the tractor for straight and accurately spaced tile lines. The grade control for this tile line was controlled "manually" by watching lights on the laser receiver. Watch the SMV sign mounted on the tile chute directly above where the tile is installed into the ground to see the grade control accuracy with only a simple manually controlled laser grade control system. Then consider whether other tile plow concepts are capable of controlling grade accurately using "only" a manually controlled laser system.
