Description
When your throttle response gets sluggish or you’re losing engine speed control during PTO work, it’s usually a stretched or worn throttle cable giving you trouble. The A6.354 engine in your MF 399 needs precise throttle input to deliver the power you’re counting on, and a failing cable can leave you with erratic speed control or no control at all when you need it most.
What You’re Getting
- Precise engine speed control that connects your throttle lever directly to the injection pump
- Durable cable construction that handles the constant adjustment during field work
- Direct replacement design that connects using original mounting points
- Heavy-duty outer sheath that resists kinking and protects against moisture
Built for Real Farm Work
The MF 399 with that A6.354 engine is built for serious pulling power – running large tillage equipment, powering forage harvesters, or pulling heavy grain carts. Whether you’re maintaining steady RPMs for PTO-driven equipment or need precise speed control for loader work, this cable gives you the throttle response your operation demands.
Made to Last
The A6.354 engine puts out substantial torque, and your throttle cable takes constant use during those long field days. This replacement uses heavy-duty construction that won’t stretch under load, with protective casing that keeps moisture and debris from causing binding or corrosion inside the cable.
Installation Notes
Route the new cable following the original path to prevent binding or interference with other components. When installing, ensure the cable routing avoids sharp edges or heat sources that could damage the casing over time. Check that both ends connect smoothly and adjust for proper throttle response from idle to full speed before putting the tractor back to work.
