The Honda 72513-750-305 Left Rotary Blade is a genuine OEM replacement designed for the HT3810 and HT3813 lawn tractors. As a direct Honda OEM part, it is manufactured to the same specifications as the blade that came on your tractor, ensuring a proper fit in the cutting deck without modification. Honda supersedes parts at serial number breaks, so confirm your tractor's serial number against the fitment table before ordering to make sure part number 72513-750-305 is the correct blade for your specific unit. Installing a correctly fitting blade keeps the cutting deck balanced and the cut quality consistent across the full mowing width.
Key Features
- Genuine OEM Cutting Geometry — made by Honda to match the original blade's lift angle and cutting edge profile, so your HT3810 or HT3813 cuts cleanly without deck vibration caused by an unbalanced or incorrectly shaped blade
- Left-Side Deck Position — this is the left rotary blade; verify which blade position your deck requires before ordering, as the left and right blades are not interchangeable
- Direct-Fit Replacement — engineered to mount in the same position as the original, with matching bolt pattern and center hole dimensions for the HT3810 and HT3813 cutting decks
- Serial Number Matters — Honda issues part supersessions at defined serial breaks; check your tractor's serial number against the compatibility table to confirm this blade applies to your unit
The rotary blade is the core cutting component of a lawn tractor's mowing deck. As the blade spins at high speed beneath the deck, its sharpened leading edge severs grass while the angled lift wings create an upward airflow that stands grass upright before the cut and propels clippings toward the discharge chute. On a twin-blade deck like the HT3810 and HT3813, each blade covers its own half of the cutting width, which is why the left and right blades must each be the correct part for that position. A worn, bent, or unbalanced blade produces ragged cuts, increased deck vibration, and uneven clipping distribution — replacing it with the correct OEM blade restores clean, consistent cutting performance.
