What This Is
This is one (1) new aftermarket spindle (mandrel) assembly for AYP-built riding mowers and lawn tractors. The assembly includes the spindle housing, shaft and bearings and is ready to bolt into the deck. The pulley, spacer and blade are not included; reuse your existing hardware or order those parts separately.
Fitment
It fits AYP, Craftsman, Husqvarna, Poulan and Roper riding mowers and lawn tractors equipped with 36 in, 38 in and 42 in ventilated mower decks, such as the popular Craftsman LT1000. Fitment on these machines is driven by deck size and mounting pattern rather than by tractor model, so confirm your deck size and the three-bolt mount before ordering.
Specifications
The spindle uses a 5-point star center hole at the blade end and mounts with a 3-bolt long housing that matches the factory pattern on these AYP decks. The shaft runs on pressed-in bearings in a cast housing and is a direct-fit replacement built to meet or exceed OEM wear specifications.
Cross-Reference
This spindle replaces AYP and Husqvarna OEM numbers 137645, 128774 and 130794, along with related factory numbers 128285, 133172, 137641 and 137646 and their 532-prefixed equivalents such as 532130794, 532137645 and 532128774. Common aftermarket cross-references include Oregon 85-017, Stens 285-464, Rotary 8549, Prime Line 192-015 and Laser 97214.
Ordering Guidance
Measure your mower deck (36 in, 38 in or 42 in) and confirm the spindle uses a 5-point star blade mount and a 3-bolt housing before ordering. This listing is for the spindle assembly only, so if you also need the matching pulley or blade, order those separately. For a full deck service, each deck position uses its own spindle, so order the quantity your deck requires.
