Tractor GPS, Auto Steer System 2.5cm Accuracy
This autosteering system delivers 2.5 cm accuracy when using RTK base R26 or CORS corrections. In PPP mode, accuracy remains competitive at 10 cm and above, eliminating ongoing network subscriptions when paired with the R26 RTK base or PPP options. It includes a built-in gyroscope, compatible spline for popular brands such as New Holland and John Deere, and multi-language support. The system supports farm measurement and AB-line visualization on its display, with installation guidance and remote diagnosis available.
Tractor GPS Guidance System 10inch Tablet with Precision AG
This package centers around a 10-inch waterproof tablet with PrecisionAG software and a high-precision GNSS board. It supports 2.5 cm accuracy via CORS and offers a robust GNSS antenna, multiple constellations, and languages. The system is designed for easy installation on John Deere and other tractors, enabling straight, curved, or history-line navigation using AB-line settings. It emphasizes user-friendly monitoring of field size and speed, making it a practical, all-day field tool.
Tractor GPS Guidance System 4inch(10cm) Accuracy by PPP
This system uses a 10-inch waterproof tablet and a high-precision GNSS board with PPP-based navigation. It guides tractors along an A-B line for straight or curved routes and supports a wide range of agricultural tasks, from sowing to harvesting. The included precisionAG software and compatible tractor brands create a flexible setup suitable for various operations, making it a solid option for farmers seeking a balance of cost and capability.
SMAJAYU JY305 Tractor GPS Guidance System
This auto-steering system uses a 10.1-inch tablet as the control hub and includes a GNSS antenna and steering wheel motor with a built-in controller. RTK can be added separately, and compatibility guidance covers brands beyond John Deere. It supports AB-line navigation and automated steering to enhance precision agriculture, with a focus on modularity and scalability for different tractor configurations and brands.
Complete Tractor Power Steering Cylinder
This steering cylinder is designed as a replacement part for Ford tractors and similar models, offering compatibility with multiple Ford/New Holland configurations. It features a 5/8″ rod and listed compatibility across several models and series. While not a guidance system by itself, it is a critical component for achieving precise steering control in older or upgraded tractors that use auto-guidance hardware.
Buying Guide
Key purchase considerations for auto guidance on tractors include accuracy needs, compatibility, and system integration. RTK-based options can deliver centimeter-level positioning, which is ideal for precise planting and row alignment, while PPP-based systems offer reliable accuracy without local base stations, suitable for farmers near network coverage. Assess whether the solution supports your tractor brand, spline type, and whether an RTK base or subscription is required.
Software and user interface matter: look for AB-line functionality, straight and curve navigation, and the ability to import farm maps or field data. A tablet-centric setup can simplify updates and troubleshooting, but ensure the device is rugged, water-resistant, and compatible with your environment. Multi-language support and remote diagnosis can reduce downtime on busy field days.
Hardware integration is another consideration. Check the availability of compatible splines, gyroscopes, and steering motor modules, especially if you plan to mix equipment brands. Evaluate installation complexity and whether professional support is offered. Finally, consider future-proofing: systems that support software updates, new satellite constellations, and expandable autosteering features can extend the life of your investment.
