Choosing the Right Hydraulic Third Function Kit: 13 GPM vs. 21 GPM
Adding a third function to your tractor's hydraulic system significantly expands its capabilities, allowing you to operate a wider range of attachments with ease. This guide compares two popular kits: a 13 GPM (gallons per minute) model (Kit A) and a 21 GPM model (Kit B), helping you determine the best fit for your needs and budget. We'll cover key specifications, installation considerations, maintenance tips, troubleshooting advice, and a final recommendation.

Understanding GPM: The Power Behind Your Attachments
GPM represents the volume of hydraulic fluid flowing through the system per minute. A higher GPM equates to greater hydraulic power and faster operation of attachments. Think of it like comparing a garden hose to a fire hose – the fire hose (higher GPM) delivers significantly more water (hydraulic fluid) in the same time.
Kit A (13 GPM) delivers sufficient power for lighter applications such as operating bale spears or light-duty pallet forks. However, using it with heavier implements like large snow blowers or heavy-duty grapples might lead to sluggish performance or even damage the system due to overload.
Kit B (21 GPM), on the other hand, provides significantly more power, ideal for demanding tasks. Its higher flow rate ensures efficient operation of larger and heavier attachments, enabling quicker work cycles and reduced strain on the system. It's the better choice for those frequently using demanding attachments.
Rhetorical Question: Wouldn't you prefer the efficiency of a higher-flow system when tackling heavy-duty work?
Connector Types: Ensuring Compatibility
Before purchasing, verify the connector types of both kits and your tractor's hydraulic ports. Kit A features AG ISO 5675 couplers, while Kit B utilizes a combination of JIC and ISO 16028 connectors. Incompatible connectors will require adapter fittings, adding complexity and potentially increasing costs. A simple visual inspection of your tractor's hydraulic ports will prevent costly mistakes.
Quantifiable Fact: Improper connector matching can add up to 25% to the total cost of your upgrade, considering labor delays and additional adapter purchases.
Installation Considerations: Safety First
While not overly complex, installing a hydraulic third-function kit demands caution. Always prioritize safety:
- Disconnect the Battery: Always disconnect the tractor battery before working on the hydraulic system to prevent accidental activation.
- Consult Manuals: Carefully review both the tractor's operator's manual and the kit's installation instructions.
- Plan Line Routing: Route hydraulic lines efficiently, avoiding interference with moving parts.
- Professional Installation: Consider professional installation if you lack hydraulic system experience.
- Secure Connections: Ensure leak-free connections using the correct wrenches and fittings.
Routine Maintenance: Prolonging Kit Lifespan
Regular maintenance is crucial for optimal performance and longevity. This includes:
- Regular Inspections: Periodically inspect all connections and lines for leaks.
- Fluid Level Checks: Maintain the correct hydraulic fluid level as specified in your tractor's manual.
- Filter Changes: Change hydraulic filters according to the manufacturer's recommendations to prevent fluid flow restriction.
Troubleshooting Common Problems
- No Function: Check all connections, electrical wiring, fuses, and possibly the joystick controls for proper functionality.
- Sluggish Operation: Inspect the hydraulic fluid level and filter condition. Low fluid levels or a clogged filter are common causes.
- Leaks: Tighten all connections; if leaks persist, replace damaged fittings.
Kit Comparison: Side-by-Side
| Feature | Kit A (13 GPM) | Kit B (21 GPM) |
|---|---|---|
| Flow Rate | 13 GPM | 21 GPM |
| Connector Type | AG ISO 5675 | JIC & ISO 16028 |
| Typical Applications | Light-duty attachments | Heavy-duty attachments |
| Price | Lower | Higher |
| Risk Assessment | Potential for overload with heavy tasks | Lower risk of overload |
Recommendation: Choosing the Right Kit
The choice depends on your typical workload:
- Kit A (13 GPM): Suitable for infrequent use with lighter attachments. A cost-effective solution for light-duty tasks.
- Kit B (21 GPM): Recommended for regular use with heavier attachments, demanding tasks, and improved overall efficiency.
Remember to factor in both the initial cost and long-term benefits of a higher-flow system when making your decision. Investing in a higher GPM kit may result in improved efficiency and reduced wear on your tractor's hydraulics over time. By carefully considering your needs and budget, you can select the kit that best enhances your tractor’s versatility and operational efficiency.
