Tractor GPS Guidance

FJD AT2 Auto Steer System & AG1 Guidance Light Bar

Stop fighting to keep your rows straight and start letting GPS do the work. FJDynamics offers two levels of precision guidance to fit your operation and your budget — the AG1 Guidance Light Bar for manual steering assistance, and the AT2 Auto Steer System for full hands-free operation. Both deliver up to 2.5 cm (1") pass-to-pass accuracy with RTK correction, work on virtually any tractor with a steering wheel (including older models back to the 1970s), and require no hydraulic modifications. Start with the AG1 and upgrade to full auto steer later, or go straight to the AT2 — either way, you'll reduce skips and overlaps, save on seed, fertilizer, and fuel, and be able to work confidently after dark.

AG1 Guidance Light Bar

The AG1 is an entry-level GPS guidance system designed for manual steering. A 10.36" touchscreen display mounts in the cab and shows your position relative to your planned path — you steer, the screen guides you. It's the most affordable way to bring precision guidance to your tractor and start reducing overlap immediately.

• Light Bar Guidance for Manual Steering
  On-screen light bar and field map show exactly where you are and where you need to go. Just follow the guidance and keep your passes consistent.
• Multiple Accuracy Levels at No Extra Cost
  Free decimeter-level accuracy via SBAS (20–50 cm) or PPP (10–20 cm). Add an RTK base station or NTRIP service for 2.5 cm accuracy.
• Wireless Plug-and-Play Setup
  The display connects to the GNSS receiver wirelessly via Wi-Fi — no wiring harness to run through the cab. Mount it and go.
• Multiple Guidance Line Types
  Straight line, curve, A+ line, pivot, and line groups — handles everything from square fields to irregular shapes, terraces, and hillsides.
• Upgradeable to AT2 Auto Steer
  When you're ready for hands-free operation, add the AT2 steering kit to your existing AG1 system without replacing the terminal or receiver.
• 10.36" HD Touchscreen
  2000x1200 resolution display with 8–10 hour battery life. Android-based with 4GB RAM and 64GB storage.

AT2 Auto Steer System

The AT2 is a complete auto steer kit that takes over the steering wheel for true hands-free operation. An electric steering motor mounts to your tractor's steering column — no hydraulic modifications required — and the system uses dual GNSS antennas with RTK correction to hold 2.5 cm accuracy pass after pass. You set the line, engage auto steer, and the tractor drives itself while you monitor implements, check your phone, or just give your neck a break.

• 2.5 cm Pass-to-Pass Accuracy
  GNSS with RTK correction keeps every pass within an inch of where it should be — whether you're planting, spraying, spreading, or harvesting.
• Electric Steering Wheel — No Hydraulic Mods
  High-torque electric motor mounts directly to the steering column. Works on 12V and 24V systems with up to 15–20 Nm of torque.
• Smart U-Turn and Auto Turn
  Automatically guides the tractor through smooth turns at the end of each row. Basic U-turn included; Smart U-turn available as an add-on for headland management on irregular fields.
• Terrain Compensation
  Built-in IMU maintains accuracy on slopes, rolling terrain, and rough ground where GPS alone would drift.
• ISOBUS Compatible
  Supports VT/TC for real-time monitoring and control of ISOBUS implements — seeders, sprayers, fertilizer spreaders — from major brands including Case IH, New Holland, Kverneland, Horsch, Lemken, and Amazone.
• Virtual Section Control & Variable Rate
  VSC and VRC capabilities let you control input application rates and shut off sections automatically to eliminate double-application on overlaps.
• Works on Old and New Tractors
  Compatible with 200+ brands and 2,000+ models. If it has a steering wheel, the AT2 can likely fit it — including tractors from the 1970s forward.
• Work at Night
  GPS guidance doesn't need daylight. Run the same accuracy at 10 PM that you do at 10 AM.

What's Included

Which One Is Right for You?

If you're new to precision ag and want to start reducing overlap without a big upfront investment, the AG1 Light Bar is the place to start. You steer — it guides. And when you're ready, it upgrades directly to full auto steer without replacing your equipment.

If you want hands-free operation now — less fatigue on long days, the ability to run after dark, and precise control of your inputs — the AT2 Auto Steer pays for itself through fuel savings, reduced input waste, and more acres covered per day.

Both systems work with the FJD Connect platform and Farm Management System for field data sync, boundary mapping, and task planning across multiple machines.
