Description
When your three-point implements aren’t working level—whether your disc harrow’s cutting unevenly, your cultivator’s running shallow on one side, or your mower deck’s scalping in spots—it’s usually your levelling box that needs attention. This adjuster kit gets your 300 series Massey Ferguson’s three-point hitch back to working like it should, giving you the precise control you need for proper implement operation.
What You’re Getting
- Complete adjuster kit with all components needed to restore proper levelling box operation
- 400mm length provides the right adjustment range for your 300 series tractor
- Quality construction that handles the constant stress of three-point hitch operation
- Direct replacement for worn or damaged original components

Built for Real Farm Work
This kit works with Massey Ferguson 300 series tractors including the 365, 375, 390, 398, and 399 models—workhorses that handle everything from cultivation and planting to mowing and loader work. Whether you’re running a compact utility operation or serious row crop farming, these tractors depend on their three-point systems for attaching and leveling implements properly.
Made to Last
Three-point hitch components take a beating from constant adjustment, vibration, and the loads of heavy implements. This adjuster kit is built with materials that stand up to farm conditions, maintaining smooth operation through seasons of fieldwork without developing play or binding that affects implement performance.
Installation Notes
Before removing your old adjuster, measure its current setting so you can start with the new one in a similar position. Clean and inspect all threads before assembly, and set the initial adjustment at mid-range to allow movement in either direction. Apply anti-seize compound to threads for easier future adjustments and to prevent corrosion.
