Product Overview
A throttle lever that moves without changing engine speed, will not stay where set, or feels unusually stiff may point to a stretched, seized, or broken cable after the governor linkage is inspected. This cable reconnects the dash control to the engine throttle mechanism.
AM121508 is the key fitment check. John Deere also used other cable lengths on some of these tractors, so measure the removed cable and compare both end bends, sheath stops, bracket locations, and the 44.5-inch overall reference before ordering.

- 44.5-inch overall length reference
- Correct end style for applications using AM121508
- Restores positive throttle travel when the original cable binds or breaks
- Flexible sheathed construction for routed control movement

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, engine or equipment configuration, installed options, and previous repairs can affect fitment. Compare the original part, identifying numbers, dimensions, connections, and mounting details before purchase.
Frequently Asked Questions
Q: Will this fit an LX178 or LX188 even though the old title omitted them? A: Yes. AM121508 is listed for LX172, LX173, LX176, LX178, LX186, and LX188; still compare the removed cable.
Q: Is AM121508 the same as every LX-series throttle cable? A: No. Similar tractors can use different cable lengths and end styles.
Q: Can a bad cable cause low engine speed? A: Yes. A stretched, slipping, or seized cable may prevent full throttle travel, though governor or carburetor issues should also be checked.
Q: Does installation require carburetor adjustment? A: Normally the cable is routed and connected to the existing linkage. Do not alter governor settings unless the service manual calls for it.
