Additional Information
The Husqvarna Lawn Tractor Mandrel Assembly (part number 587820301) replaces 587125401 and includes the mandrel shaft, housing, bearings, and four self-tapping bolts for secure installation. This part connects directly to the mower deck and drives the spinning motion of the blades.
If your lawn tractor leaves uncut patches or the blades fail to spin properly, a damaged mandrel assembly could be the cause. Replacing it helps restore consistent blade movement for even mowing results.
During installation, use the included self-tapping bolts to secure the housing to the deck ? the mounting holes are not pre-threaded. Disconnect the spark plug and wear work gloves to protect your hands while handling sharp or heavy parts.
Replacing worn or noisy mandrels is a key part of mower maintenance that helps keep your lawn tractor cutting smoothly throughout the season.
