Description
If you’ve spent time operating an Allis Chalmers D10 through D19, you know those three hydraulic control knobs get handled constantly—raising and lowering implements, adjusting hydraulic flow, and controlling remote cylinders. When these knobs get cracked, worn smooth, or go missing altogether, it makes precise hydraulic control a real challenge, especially when you’re wearing gloves.
What You’re Getting
- Durable construction that handles daily use and weather exposure
- Proper grip texture that works whether your hands are clean, muddy, or oily
- Direct replacement design—threads on just like the original
- Individual sale lets you replace just the worn ones instead of buying a whole set
- Matches original appearance to keep your vintage tractor looking right
Built for Real Farm Work
This knob fits the D10, D12, D14, D15, D17, and D19 tractors that were the workhorses of many farming operations, plus the 116 and 122 lawn and garden models that still see regular use around smaller properties. Whether you’re running a vintage D17 for hay work or keeping a garden tractor going for mowing and light chores, these knobs restore that positive control you need.
Made to Last
Hydraulic control knobs take more punishment than most folks realize. They’re constantly gripped, twisted, and exposed to sun, rain, and hydraulic fluid. This replacement uses quality materials that resist cracking and maintain their grip texture season after season, just like the originals did when these tractors were new.
Installation Notes
Installation is straightforward—the knob threads directly onto the control valve stem. Clean any dirt or old thread compound off the stem before installing. Since three knobs are used per tractor, check all of them while you’re at it. A little thread locker isn’t a bad idea if you’re in rough, vibration-heavy work.
