APS Precision Seeding Control Kit
Keep your seeding rate steady and reduce overlap at headlands.
The FJD APS adds electric motor drive and high-precision positioning to a traditional seed drill. It adjusts the seeding rate as ground speed changes, starts and stops seed flow when the implement is lowered or raised, and works with ISOBUS terminals. FJD lists actual seeding-rate deviation within ±2% and seed savings of 3–5% from stopping flow at headlands.
Best for: Farmers upgrading traditional seed drills with automatic seeding-rate control.

What the FJD APS does for you
Steady Seeding Rate
The motor drives the seed metering shaft directly instead of relying on drill wheels. This helps maintain the target rate on wet ground, slopes, and at changing speeds.
Automatic Start And Stop
The system detects when the implement is raised or lowered. It starts planting when the drill reaches the ground and stops seed flow when the drill is lifted.
Quick Rate Changes
Change the seeding rate from the terminal screen. There is no need to stop for manual gear changes or calibration tests.
Precision Guidance Support
The APS can work with FJD autosteering systems for ±2.5 cm RTK guidance. It can also connect to ISOBUS-compatible navigation terminals from other brands.
Seed Monitoring Alerts
The system includes smart alerting and infrared optical seed sensing. The sensor sends a pulse signal and can detect up to 40–60 seeds per second.
Operation Data Management
The kit includes operation data management features for planting work. Contact DST for help determining how those features fit your terminal and setup.

Common questions
Will this work with my existing seed drill?
The APS is built as an upgrade for traditional seed drills. Call DST with your drill model and setup so we can help confirm compatibility.
Can I change the seeding rate without stopping?
Yes. The seeding rate can be adjusted on the terminal screen, without manual gear changes or a calibration test.
Does it stop planting at the headlands?
Yes. The system detects when the implement is raised and stops seed flow. It starts again when the implement reaches the ground.
