Tractors are super important for farming today, and how they steer makes a big difference in how well they work and how easy they are to use. If you want to make your tractor's steering better, FJD makes reliable, accurate hydraulic autosteering systems in three types: AS2 (CANBUS), AS2 (Non-CANBUS), and AH2. How do you choose the one that best fits your needs? This guide will help you pick the best option quickly!


Why Choose FJD Hydraulic Steering Systems?

FJD hydraulic autosteering systems are a simple upgrade for your tractor that saves you effort and money. You get to keep your current steering wheel, so you don't have to replace it like you would with autosteer systems from other brands. Installation is easier, and your tractor will still feel familiar to drive. This is great for farmers who want a reliable system without extra expenses.
Hydraulic steering gives you smoother and more accurate control compared to motor-powered systems. It reacts instantly to how you want to steer, which makes it easier and safer to handle tough jobs like plowing, hauling, or driving on bumpy ground. This stable steering is especially important when you need to avoid mistakes or accidents.
FJD steering systems fit almost any tractor, whether it's a smaller 140HP model or a big 500HP one. It doesn't matter if you have a John Deere, Case IH, or a 30-year-old tractor, you can probably use an FJD hydraulic steering system. This makes upgrading your tractor easier, so you can get back to work.
 
Here's a quick look at your three choices for FJD hydraulic-control steering systems:
  • AS2 (CANBUS): This works with steer-ready tractors that are already set up for automatic steering. It communicates with the tractor's steering system via the CAN protocol.
  • AS2 (Non-Canbus): This also works with tractors ready for automatic steering. Instead of using the CAN protocol, it uses a different way to communicate, called "PWM signal" (a pulse-based control signal), with the tractor's steering valve (need specific functionality support).
  • AH2: This option requires you to install an FJD hydraulic valve to take control of the tractor's steering.



How to Choose in 3 Simple Steps

Step 1: Identify your tractor's brand and model
  • AS2 (CANBUS): Suitable for high-end series/models of brands that are steer-ready and run on CANBUS protocol, such as Case, New Holland, Massey Ferguson, and Fendt.
  • AS2 (Non-CANBUS): Work with non-CANBUS vehicles that are already equipped with assisted steering systems, such as early models from Case, New Holland, and John Deere.
  • AH2: It is generally applicable to tractors with a theoretical horsepower range of 140HP to 500HP. Check the tractor's hydraulic specifications to ensure they fall within the AH2's operating parameters. Some tractors might require modifications or adapters to ensure seamless integration.

Step 2: Check the brands and specs of your steering unit/valve
  • AS2 (CANBUS): Work perfectly with Danfoss OSPE steering unit and hydraulic valve.
  • AS2 (Non-Canbus): Integrate seamlessly with valves that output PWM signals, such as Eaton, Fema, and Rexroth.
  • AH2: Recommended for vehicles with 140HP to 500HP that cannot achieve steer-ready functionality. Select the corresponding FJD valve based on flow rate/horsepower and valve type.

Step 3: Look for physical appearance and consider horsepower
  • AS2: A steer-ready tractor is usually equipped with dedicated buttons in the cab, such as OFFLOAD and AUTO buttons for CANBUS tractors whereas an AUTO button for Non-CANBUS types. If it cannot be used, check if the Steer Ready function is unlocked or if the CAN signal cable is connected properly.
  • AH2: Offer 4 valve types with open-center and closed-center options. Generally, for 140HP to 300HP, choose a 30L/min valve; and for 300HP to 500HP, choose a 60L/min valve. Before selecting a 60L/min valve, you need to check your tractor's hydraulic system and valve type.



Final Tips

Before you buy an FJD hydraulic steering system, make sure to read the installation guides carefully. This will help you be sure it will work with your setup and that you can install it easily. If you're not sure about anything when you're choosing or installing the system, call FJD's tech support and let them help you.
Especially, if you're considering an AH2 system, pay very close attention to the flow rates and the valve types needed. If these are wrong or don't match, the whole system won't work as well as it should.

Conclusion

Choosing the right FJD hydraulic steering for your tractor doesn't have to be hard. Whether you have a brand-new Case IH or an older John Deere, FJD has options to make steering easier and improve how well your tractor works. The AS2 (CANBUS) model is great for newer, high-tech tractors that use CANBUS systems; the AS2 (Non-CANBUS) model is made for tractors that use PWM signals with specific steering valve models, and the AH2 is a flexible option that can work with almost any tractor's hydraulic system.
If you're still not sure which one is best for you, the FJD support team is available to help you pick the right system, so you can enjoy smooth and easy steering. Just call your local FJD distributors or leave a message here: Contact FJDynamics
