Transform Your Tractor’s Capability with Professional Remote Installation
Executive Summary
Adding rear hydraulic remotes to Kubota tractors transforms machine capability by enabling operation of hydraulic implements at the rear of the tractor. This comprehensive guide covers everything from benefits and kit selection to detailed installation procedures and troubleshooting for B, L, and MX series tractors, helping you add rear remotes to Kubota tractors efficiently and safely.
Benefits of Rear Hydraulic Remotes
Primary Applications
When you add rear remotes to Kubota tractors, you unlock numerous operational capabilities that dramatically improve productivity and versatility.
Top-and-Tilt Cylinders: Rear remotes enable precise control of Category 1 top-and-tilt cylinder systems, allowing operators to adjust implement angle and position for optimal field conditions. This allows easy control of various hydraulic implements at the rear using Summit Hydraulics joystick and switchbox controls.
Log Splitter Operation: The third function commonly adds log splitter capability. Rear remotes provide the hydraulic power needed for high-pressure log splitting operations, typically requiring 2,000-3,500 PSI operating pressure.
Grapple Trailer Control: Hydraulic grapple trailers benefit significantly from rear remote installation, enabling operators to control opening and closing functions from the cab without manual operation.
Additional Implement Applications
- Rake systems for hay and debris management
- Disc mowers for precision cutting operations
- Rear blade hydraulic angle adjustment
- Hydraulic top link cylinders for draft control
Operational Advantages
Enhanced Productivity: Installation reduces implement change time by eliminating manual hydraulic connections, with users reporting up to 50% faster implement switching when you properly add rear remotes to Kubota tractors.
Improved Safety: Cab-based control eliminates the need to exit the tractor for hydraulic adjustments, reducing operator exposure to moving machinery.
Precision Control: Modern joystick and switchbox systems provide fine control over hydraulic functions, enabling more precise implement operation.

Frequently Asked Questions
Q: Can I install rear hydraulic remotes on any Kubota tractor model?
Most modern Kubota B, L, and MX series tractors can accommodate rear hydraulic remotes, but compatibility varies by specific model and year. B2301, B2601, L2501, L3301, L3901, L4701, and MX series tractors have the best compatibility with both OEM and aftermarket kits.
Q: What’s the difference between single, double, and triple valve systems?
Single valve systems provide one hydraulic function (10-15 GPM), double valve systems offer two functions (15-20 GPM combined), and triple valve systems provide three functions (20-25 GPM combined). Choose based on your implement requirements and budget, with double valve systems being most popular for general farm applications.
Q: How much can I save by installing aftermarket remotes versus OEM kits?
Aftermarket kits typically cost 50-70% less than OEM solutions, with potential savings of $300-$800 on parts alone. Including DIY installation, total savings can reach $800-$1,200 compared to dealer-installed OEM systems, though you may sacrifice some warranty coverage and perfect fit guarantee.
Q: Do I need to drain the hydraulic system before installation?
You don’t need to drain the entire hydraulic system, but you must depressurize it completely before beginning work. Run the engine at idle for 2 minutes, cycle all hydraulic functions 3-4 times, lower all implements, then shut off the engine and wait 10 minutes for complete pressure relief before starting installation.
