Questions & Answers

Are the blades balanced from the factory?

Asked by: Madmax
Yes.You just put them on and go.

What is the proper pound of torque for blade application for the D-105 model?

Asked by: Madmax
I couldn't find a recommended torque value in the owner's manual. I tighten them snug plus one turn. The centripital force of the rotation would normally be tightening, but the star pattern prevents this. Replace the nuts after 5 cycles of changing the blades to ensure their "locking" ability.

Are they a high lift blades for bagging

Are they a high lift blades for bagging
Asked by: JD
Thank you for visiting The Home Depot website. These blades are our standard 3-1 blades that are able to side discharge, mulch and bag. The high lift blades for a 42 inch mower with a star hole connection would be part# AM141034.

42 in. Mower Blades (2-Pack) is rated 4.5 out of 5 by 56.
Rated 4 out of 5 by from I really wish HD would sell the MULCHING blades. ... I really wish HD would sell the MULCHING blades. This blade is the "3N1" blade and doesn't mulch as effectively as the actual dedicated mulching blades for the John Deere.

We have a large yard and these new blades made all the difference in how the yard looks when you're done mowing. They were very easy to replace. I love a nice smooth yard and these did the trick. As soon as I got them on I finished mowing and I didn't have to go over things a couple times to make it look nice.

They are a very quality product at a good price. Haven't used them but one time and if I can stay off the rocks Maybe they will hold up for awhile. The cut was great.

I bought them because they are advertised as triple usage (cut, mulch and bagging). I'll update in the Fall for the bagging part.
