Product Description

?

This replacement mulching blade is an OEM sourced high quality part that is commonly utilized on Husqvarna and Poulan riding lawn mowers. Mulching blades are designed with a higher curve to circulate the grass longer under the deck so it can be cut into smaller pieces. This makes the clippings better as mulch since smaller pieces will decompose quicker releasing nutrients into the soil. This part is made from strong durable steel and it is sold individually. To replace it you will need a wrench to remove and secure the blade bolt.
