Make every pass more productive with integrated guidance system from John Deere Ag Management Solutions.
Start with Parallel Tracking and the free SF1 signal. This hands-on system lets you reduce overlap and is ideal for broad-acre tillage, seeding, and spraying. When you demand great accuracy, upgrade to hands-free AutoTrac™ Assisted Steering. Then choose AutoTrac SF1 with an accuracy of +/-13 inches at the receiver, or go with AutoTrac SF2 for +/- 4 inches of accuracy.
AutoTrac lets you work at faster speeds so you finish more acres in less time. Plus, by minimizing implement overlap, you can decrease fuel, seed, fertilizer, and chemical costs.

Signal accuracy options
The StarFire™ network provides unparalleled signal reliability:

• SF1– FREE, pass-to-pass accuracy of about 1 foot
• SF2 pass-to-pass accuracy of +/-4 inches
• StarFire RTK - Real-time kinematics with sub-inch accuracy
  Note: SF1 and SF2-15 minutes pass-to-pass, 95 percent of the time. RTK - sub-inch - within 6 miles of base station and 68 percent of the time.
• The sub-inch accuracy of AutoTrac RTK is ideal for high-value-crop applications, such as pulling this onion bedder above.

GreenStar guidance advantages

• Repeatable sub-inch accuracy

Field Doc™ Data Collection Software can turn your tractor into an information gathering machine. Working with your StarFire receiver and GreenStar monitor, this GPS-based software simplifies data collection - recording field and weather conditions, tillage practices, seed varieties, and field boundaries.

The original GreenStar system provides an affordable option for guidance and field documentation applications. GreenStar 2 System color display: The GSD 2600 (left) features push-button or touch-screen navigation. It comes pre-loaded with a wide array of John Deere Ag Management Solutions programs. Plus it can pull double-duty and work as your tractor's performance monitor.
