Oregon 91-539

This is a genuine Oregon OEM Replacement Mulcher Blade. Mulching blades generally have a more curved surface with two distinct cutting planes along the blade's edge. Older style mulching mowers actually included two blades arranged perpendicular to each other. When a baffle or mulch kit is installed on the mowing deck to prevent clippings from discharging, mulching blades circulate the clippings beneath the deck where they're cut and re-cut into tiny pieces. The finer clippings will decompose more quickly, releasing nutrients into the soil. Mulching blades may be referred to as 3-in-1 blades or all-purpose blades because they can be used to mulch, discharge or bag clippings. 

If you need assistance in verifying that this Mulcher Blade will fit your mower we will be more than happy to assist you. Give us a call or email us, be sure to have your model and serial number handy.
