Ditch Assist Equipment Compatibility
Grade Control for Pull Type Scrapers
Ditch Assist delivers precise RTK GPS grade control for any hydraulically operated pull-type scraper using our Full Automation Kit which includes hydraulic valve and all required hoses and fittings. The Automation Kit also features a hydraulic bypass circuit allowing you manually operate the scraper raise and lower hydraulics at any time.
Ditch Assist makes it easy to achieve accurate surface drainage and land-leveling results. Our standard hydraulic valve provides reliable and precise blade control for typical scrapers used in Western Canada and the Northern U.S., with easily adjustable hydraulic responsiveness via min/max Duty Cycle (DC) settings in the Ditch Assist app. Turn up DC for larger scrapers, or lower it slightly for smaller units. Optional high-flow valve spool upgrades are available for extra-large scrapers—contact us at 1-877-354-2899 to discuss your specific needs.
Because the Ditch Assist valve is portable and typically mounted on the implement (or tractor), it’s easy to switch between tractors or implements throughout the day. Simply weld additional mounts on other equipment or mount the valve on the tractor if frequently switching implements. Wireless communication from valve to cab means minimal wiring, allowing you to change tractors and be back grading in under an hour.
Advanced features like Slope-IQ help you achieve optimal best-fit drainage designs, while our Auto Nudge function allows precise control of maximum cut depth per pass—eliminating excessive cuts that can stall your tractor. Just increment the pass number after each run to gradually achieve the desired final grade.
Ditch Assist works seamlessly with any RTK GPS system. If you need an affordable RTK solution, ask us about the reliable Emlid Reach RS3.
Grade Control for Rotary Ditchers
Ditch Assist delivers precision RTK GPS grade control for rotary ditchers including popular brands like T-REX Ditcher™, Wolverine Ditcher™, and Revolution Ditcher™. Our standard Full Automation Kit includes a hydraulic valve, hoses, fittings, and a convenient hydraulic bypass for manual control at any time, ensuring precise and reliable grade adjustments.
If you own a Revolution Ditcher™, Ditch Assist seamlessly integrates with its factory-installed PWM hydraulic valve. This means you only need our affordable Guidance Only Kit, providing a simple plug-and-play connection without purchasing additional valves or hydraulic components. Owners of other ditcher models with existing valves should contact us to confirm compatibility; however, the full Automation Kit is typically required.
Wireless connectivity reduces cab wiring, and the easily adjustable min/max Duty Cycle (DC) settings in the Ditch Assist app offer optimized hydraulic responsiveness for different ditcher models and sizes. The portable valve allows quick switching between tractors or implements, getting you back to ditching in under an hour.
Advanced features like Slope-IQ provide best-fit ditch designs, while Auto Nudge controls maximum cut depth per pass, preventing excessive depth that could stall your tractor. Simply increment pass numbers after each run to gradually achieve your desired grade.
Compatible with any RTK GPS system, Ditch Assist also pairs perfectly with affordable, reliable RTK receivers like the Emlid Reach RS3. Call us at 1-877-354-2899 for details or compatibility questions.
Grade Control for Blades and Land Levelers
Ditch Assist provides reliable RTK GPS grade control for a wide range of blades and land-leveling equipment, including popular implements like the Pulldozer™. Our Full Automation Kit enables accurate, automated hydraulic control of the blade height, delivering precise field leveling and consistent drainage results.
Ditch Assist focuses exclusively on automating the raise/lower hydraulics for precise grade adjustments. Additional blade functions, such as tilt or side-wing adjustments, remain manually operated by the user. For tilt-capable blades, Ditch Assist will work correctly provided you keep the tilt angle constant from the initial survey through to grading. Changing the tilt angle mid-operation alters the GPS height offset, causing deviation from your intended grade.
One major advantage of Ditch Assist for land leveling is the ability to import custom-designed leveling maps created with third-party software such as OptiSurface™, AgForm 3d™, and Ezigrade™. These designs, exported as simple text files with target elevations, are easily loaded into the Ditch Assist app. Ditch Assist then automatically adjusts blade height in real-time to achieve the exact design elevations. Additionally, our Auto Nudge feature works seamlessly with these imported designs, incrementally lowering your blade each pass based on original survey data included in your leveling file.
As with all Ditch Assist applications, our wireless valve setup allows you to rapidly switch tractors or implements, ensuring minimal downtime between tasks. Compatible with any RTK GPS system, Ditch Assist also pairs perfectly with cost-effective RTK solutions like the Emlid Reach RS3.
For specific compatibility questions or detailed information on importing custom designs, please call us at 1-877-354-2899.
Grade Control for Tile Drainage Plows
Ditch Assist delivers accurate, RTK-based hydraulic control for tile drainage plows, providing all the functionality you’d expect from traditional laser control systems—plus significant advantages. Features like our exclusive Slope-IQ™ technology provide automatic best-fit grade calculations, and the system allows custom designs specifically tailored to tile drainage applications, ensuring efficient and precise installation.
Unlike dedicated tile-plow controllers, Ditch Assist does not include a pitch sensor and will not automatically compensate for changes in plow pitch. For optimal performance, tile installation runs should always progress uphill, and operators should monitor pitch using built-in visual gauges (such as water-level indicators found on many plows). If the plow hits a rock and deflects upward, causing it to pitch downward as it attempts to return to the design grade, operators will need to manually nudge the plow upward or restart the run from the point of impact.
Ditch Assist integrates seamlessly with factory-installed hydraulic valves on the Soil-Max™ Stealth ZD plow, providing a cost-effective, plug-and-play solution. It also pairs perfectly with dual-linkage plows like the O’Connell™ Drainage Plow, which maintain consistent positive pitch without the need for automatic pitch adjustment.
Combine the convenience of RTK GPS with powerful software features to streamline your tile drainage installations. Ditch Assist is fully compatible with any RTK GPS system, including the affordable and reliable Emlid Reach RS3. Contact us at 1-877-354-2899 for specific compatibility or additional details.
