Mower: 2008 Poulan Pro PR160Y21RDP
Honda GCV160-LAS3A 5.5 hp engine
Two sharpened original 21 inch mulching blades
I didn't have any problem with this last year or earlier this mowing season. I just started having it happen the last 4 times I've mowed. When I mow, it will leave 1 or 2 blades of grass standing per step I take. I have tried walking really slow to see if maybe I was walking too fast but that didn't help. I bought a new blade that is on the parts list of my mower to see if maybe the blade had gone bad somehow. That didn't help. Could it be something with the engine not running fast enough to get the blade rotating quickly enough? I don't know much about engines but with directions I am not afraid to try to fix things myself. I just ordered a mulching plug for the bagging chute so that doesn't get filled up with grass. Could that be causing it? It seems like it's just not getting enough lift. Thank you for any help.

Mulching plug is good idea. When discussing blades, they need to be cleaned first, then inspected for go or no go, and if found to be in good shape, dressed up, not sharpened, with file etc. and lastly balanced before installation.

I thoroughly cleaned out the deck on my mower last night and cleaned up the blade. I should be getting my mulching blade tomorrow so we'll see if that helps much.
