Tile Plow Control System

Ag Leader’s Intellislope® simplifies the process of installing farm drainage tile through its RTK GPS receiver, which installs tile on grade throughout the entire run. Laser surveying equipment and adjustments during tiling are obsolete. The Intellislope makes the process more accurate and reliable, no longer subject to fluctuating weather conditions or grade variations in changing topography.

Get The Maximum Yield With Intellislope®

Easy and effective field drainage.

Are you getting the maximum yield from your fields? Our farm drainage plows pay for themselves with compounding benefits through the years. They improve soil tilth for better root development, lengthen planting windows, and provide better nutrient access for crops by removing excess moisture from the soil profile. The Intellislope functionality is available through the Ag Leader® display and provides tile plow control for easy and effective installation of a field drainage system.

“We have put in around 900,000 feet of tile. When we tile a field the neighbors stop by and ask us to install tile for them. We originally purchased the plow just to do our own work but it has grown into more work than we can handle. The Soil-Max Gold Digger is the best investment we have made. P.S. It is also very good exercise for the three of us.””

Easy Installation, Planning, and Record Keeping


Can be done ahead of time with an ATV, or at the time of installation with the tile plow utilizing RTK GPS. Collect surveys by driving over the path where tile needs to be placed to collect the surface elevation.


Enter the desired minimum/maximum and target depths, as well as the minimum grade to drain excess water from the field. This can be done in the field or with the SMS TM Advanced Water Management Module.


Use the plan you created to install tile using AutoTile® to adjust the depth of the plow automatically. Grade control or pitch control modes can also be used as needed.

Root Development

Well-Drained Soils

Encourages deeper root development and healthier crops.

Saturated Soils 

Leads to shallow root growth and poor plant development.

Grade & Pitch Control

Plow Control Systems Simplified

Grade Control

If you have used laser-equipped drainage plows in the past, our Grade Control will be a welcome innovation using GPS instead of lasers to make tile installation simpler and smarter. GPS allows you to set the desired grade to install tile and if needed, use grade breaks to shallow up but keep the same grade.

Pitch Control

If your RTK GPS signal is ever lost, Pitch Control mode (with a pitch plow) can finish the run. This functional mode uses the pitch sensor in the Water Management Module to guide the plow at a specific pitch.

The Value of Data

Accurate field data is an invaluable resource in helping you make better management decisions

  • Utilize your existing yield maps to determine where tile is needed on your farm.
  • Take advantage of automated Soil Survey downloads to have additional reference layers for planning your tile installation. 
  • Track yield improvements where tile has been installed.
