Replacement Blades are "MADE TO FIT" - NOT an OEM part
To ensure that we ship the correct replacement blade for your mower, please match the OEM # or the measurement of your blade (measure from top left to bottom right of Blade or top right to bottom left of blade for length).
Check your manufacturer's part number in your owner's manual or parts list. The OEM # listed should match that number. If your manufacturer's part number is not listed, call us toll free 800-345-0169 and we will check our complete stock of blades, and/or see if we can get it for you!
Please follow your Mower Manufacturer's Installation Guidelines exactly when installing blades. Failure to follow such guidelines may result in property damage, personal injury, or death.
