The Honda 72531-752-J00 Rotary Blade is a genuine OEM replacement designed for CD4542 and CD4546 lawn tractors and the MM46 multi-purpose tractor. As a direct OEM replacement, this blade is sourced and manufactured to the same specifications as the original, ensuring the cutting performance your machine was built to deliver. Buyers should confirm their unit's serial number against the fitment table, as Honda supersedes blade part numbers at production breaks — matching the serial range to your tractor is the surest way to confirm this is the correct blade for your deck.
Key Features
- OEM Cutting Integrity — manufactured to Honda's original blade geometry, including correct lift angle and cutting-edge profile, so your tractor delivers the same quality of cut as it did from the factory floor.
- Direct OEM Replacement — engineered to drop into the deck of the CD4542, CD4546, and MM46 without modification, using the same mounting configuration as the original blade.
- Serial Number Verification Recommended — Honda updates blade part numbers at specific production intervals; check your tractor's serial number against the fitment table before ordering to ensure an exact match.
- Cutting Performance — a worn or damaged rotary blade produces ragged, uneven cuts and forces the engine to work harder; replacing it on schedule restores clean results and reduces strain on the deck drive system.
A rotary blade is the core cutting component of a lawn or multi-purpose tractor deck. Mounted beneath the deck and driven by the blade engagement system, it spins at high speed to shear grass cleanly at a set cutting height. The blade's lift angle also draws clippings upward for even distribution or collection, depending on the deck configuration. When a blade becomes dull, bent, or out of balance, cut quality deteriorates noticeably — grass may be torn rather than cut, and vibration through the deck can signal that replacement is overdue.
