AUTOMUTO Spindle Kit (Set of 2) — 107-8504 / Stens 285-881 for Z Master Z400 Z500 GrandStand Zero-Turn Mowers

Replacement spindle kit (set of 2) compatible with models: Toro Z400, Z410, Z441, Z449, Z450, Z453, Z500 and Z528 — part number 107-8504. Ideal as a direct-fit spindle assembly for Z Master and GrandStand zero-turn mowers. Maintenance tips: The spindles and caster wheels are typically the components that require greasing most often. For most residential users, greasing these parts around once a month keeps moving internal components operating properly. Mowers used in commercial settings that accumulate hundreds of hours may require greasing every day, depending on workload and conditions. Avoid over-greasing: Applying too much grease can be damaging. Over-greasing bearings may cause abnormally high operating temperatures, harm seals, and in some cases — for example with electric motors — lead to energy complications and failure. Quality and fitment: Each part is carefully inspected and measured to ensure it meets spindle manufacturer specifications and internal quality standards. All replacement components conform to OEM specifications and are guaranteed to exceed OEM requirements. Important: Please verify your mower model and part numbers before ordering to confirm fitment.
