Mower Gator Mulching Blades for 46 in Deck - Durable Cut Quality

Our review of the Mower Gator mulching blades finds them best suited for owners of 46 in garden tractors and zero-turn mowers who want a direct OEM replacement with good durability. These blades are a straightforward swap for machines that use part numbers like 403107 or 532403107 and the biggest reason to buy is reliable fit and construction: the 22-7/8 in diagonal length, 0.150 in thickness and 5-point star center hole match many 46 in decks for a trouble-free install. The blades arrive with the cutting edge pre-sharpened and painted for safe handling, a small detail that signals practical assembly and immediate use.

Key Features

• Exact fit dimensions: The 22-7/8 in length and 5-point star center hole ensure a secure, direct replacement on compatible 46 in decks without modification.
• Durable construction: At 0.150 in thickness the steel blade is designed to resist bending and hold an edge under regular homeowner mowing conditions.
• Pre-sharpened safety finish: The cutting edge is sharpened then painted to protect installers, and the paint wears off quickly during normal use.
• Wide vehicle compatibility: Lists of compatible models span Husqvarna, Craftsman, Poulan and Ariens type mowers so owners can confirm fit by OEM part numbers.
• Mulching profile: The Air Lift 1 in and 8-21/32 in cutting edge length are intended to improve lift and clippings circulation for mulching on a 46 in deck.

Who It's For

These blades are for homeowners and small property managers who run tractors or ZTR mowers with a 46 in deck and need a like-for-like replacement for OEM numbers such as 403107 or 532403107. The product is especially useful when a quick, bolt-on swap is required and matching the center hole and diagonal length is critical.

Those seeking ultra-high-end professional mulching performance or specialized blades for extremely wet, woody conditions should consider purpose-built mulching systems or commercial-grade blades instead, because while these blades perform well for general mulching and clipping return, a dedicated commercial option may deliver longer life under heavy daily use.

Specifications
