                Answer This Question

                Thank you for your question. This would not be the correct replacement for your model mower, as this has the wrong centerhole. At this time, we do not carry a commercial mulching blade replacement for your model mower, only a standard version - part number 561814B. Thank you for your interest in MaxPower parts.

                  These cut really well. But I don’t have in

                  These mulching blades cut my mowing time in half. Installation was simple. Tip: use a 2x4 to hold the old blade in place during removal. Side discharge through the chute is much less, making mowing quicker and cleaner. I would definitely buy again. Far exceeded expectations.

                  I have used a set for over a year. This set is so I can keep a sharpened set to exchange each year.

                  I was impressed with how well these blades were able to mulch not only leaves but also small twigs and other brush. It made clearing the yard much easier this year.

                  Notice a slight imbalance vibration from these blades at idle. But does the job of mulching.

                  The pruct works okay. But has to be cleaned about 2 times during my session. If not, it bogs down and stops after about 20 to 30 minutes of cutting the grass
