Product Overview
An attachment that will not lock or unlock, moves slowly, stops mid-stroke, or shows intermittent quick-tach operation may have an actuator fault. Switch input, voltage under load, wiring, controller output, hydraulic lock cylinders, linkage, pins, and debris must also be checked.
AT424407 is shown as a superseded actuator in some applications, but voltage and geometry vary. Match the original number, machine serial, plug, retracted length, mounting-pin centers, shaft ends, stroke, and voltage marking.
Key Features & Performance
- Moves the quick-attach locking mechanism after receiving the machine control command
- Powered attachment-lock actuator for the stated loader applications
- Cross-reference and machine-model data support serial-level verification
- Cross-references AT494284, AT424407, AT361276, AT471581 and related numbers

Compatibility Notice
Northline Parts does its best to list all known compatible models, but the correct part may fit an application not shown.
Model, production date, serial number, electrical or fuel-system version, dimensions, installed options, and previous repairs can affect fitment. Compare the original part and application information before purchase.
Frequently Asked Questions
Q: Will this fix quick-tach pins that are mechanically seized? A: No. The lock cylinders, pins, linkage, and attachment interface must move freely before the actuator is installed.
Q: Why must the original actuator number be checked? A: Supersessions and machine revisions can change voltage, stroke, mounting geometry, and connectors.
Q: How do I confirm fitment before ordering? A: Match the original reference number where available, then compare the removed part, dimensions, connections, mounting details, model, serial or production information, and package photos.
Q: Is this an original-equipment part? A: No. This is a new aftermarket part. Brand names and reference numbers are used only to identify compatible applications.
