What Is the Float Detent—and Why It Matters
The float position is a loader control setting that disengages hydraulic force, allowing the bucket or arms to contour to the ground under their own weight. A detent is a small notch or mechanism—either in the joystick or valve—that helps hold the control in float position. When this detent fails, the loader may not float properly, leading to jerky movement or failure to settle smoothly.
Terminology Explained
A Mini-Story from the Field
A farmer affectionately referred to his Deere as his “baby”—mostly gentle with moderate use. He noticed that when pushing the joystick fully forward, the loader didn’t stay in float; it acted like it was bouncing, pressure applied on both directions. Other functions worked fine. A seasoned technician pointed out: “The detent isn’t actually in the stick—it’s inside the valve down there. And yes, it’s fixable.” Indeed, a $60 kit restored his loader’s float detent, and the “baby” was back to behaving properly—after only a mechanic’s diagnostic fee or two.
Common Float-Related Loader Issues
Troubleshooting Checklist
Suggested Repair Steps
Real-World Scenario
A neighbor raised bales of hay regularly with a loader. One winter, he noticed the bucket sometimes floated unevenly, catching on edges. Rather than ignore it, he replaced the detent parts in the valve. Loader performance returned to smooth operation—and he avoided costly trips to the dealer and downtime in hay season.
Conclusion
Loader float issues—whether not engaging or failing to hold—often trace back to subtle detent wear inside the valve. Rather than assume joystick failure or worse hydraulic glitch, tackle the valve detent first. A simple repair kit can restore smooth operation and save both time and money. If your loader acts strangely when attempting float, start here—it’s where your Deere will likely appreciate the TLC.

Terminology Explained
- Float Detent: A mechanism that holds the loader control in float mode.
- Control Valve Detent: The actual notch or catch is in the valve assembly—not always in the joystick.
- Hydraulic Levers and Joysticks: Input devices that engage or release hydraulics; their mechanical play or adjustment can influence operation.
- Hydraulic Float Function: Mode where loader arms descend freely, guided by weight instead of hydraulic pressure.

Common Float-Related Loader Issues
- Float Doesn’t Engage
- Control lever moves freely but won’t activate float mode. Could require valve detent kit or joystick adjustment.
- Control lever moves freely but won’t activate float mode. Could require valve detent kit or joystick adjustment.
- Float Activates But Doesn’t Hold
- Loader enters float but immediately reverts to neutral. Likely a worn or weak detent mechanism.
- Loader enters float but immediately reverts to neutral. Likely a worn or weak detent mechanism.
- Joystick Feels Loose or Sticky
- Excessive play or stiffness in the joystick may be felt but the real issue might be deeper in the valve.
- Excessive play or stiffness in the joystick may be felt but the real issue might be deeper in the valve.
Troubleshooting Checklist
- Test Float Activation: With the bucket a couple inches above ground, push joystick fully forward. Does the loader settle—or resist?
- Check Holding: Keep joystick forward—does it return to neutral on its own? That indicates a detent that won’t hold.
- Joystick Movement vs. Valve Action: If all other loader functions work fine, the joystick is likely not the root cause—turn your attention to the valve.
- Detent Repair Kit: A modest investment—often under $100—can fix float-holding issues and save big repair bills downstream.
Suggested Repair Steps
- Begin with simple movements and observe whether float engages and holds.
- If float works but doesn’t stay—order a valve detent kit; it typically includes springs, notched mechanism, and seals.
- If joystick feels sloppy or unresponsive, check for linkage play, but don’t ignore valve-side components.
- After installation, test float again under load—fully forward, let bucket settle, then pull back. It should stay until actively moved out of float.
