## Long description

Replacement lawn mower blade Scheppach MS173-51 is a steel cutting blade made for lawn mowers with a 51 cm cutting width. It is intended as a direct replacement for worn or damaged blades on compatible Scheppach push or ride-on mowers specified for the MS173-51 deck size, restoring cutting performance and uniform grass discharge across the 51 cm deck.
Advantages
The blade is manufactured from hardened steel designed to maintain edge retention under normal mowing conditions. Its geometry is matched to the 51 cm deck to provide even cut quality and reduce scalping or uneven discharge. Installing a correctly sized replacement blade helps restore the mower's original cutting pattern and reduces vibration caused by imbalanced or damaged blades.
Suitable for
Routine maintenance and scheduled blade replacement on compatible Scheppach mowers
Replacing bent or nicked blades after strikes with stones or roots
Restoring even cutting and proper grass discharge across a 51 cm deck
Key specifications
Material: hardened steel construction for durability
Designed cutting width: 51 cm deck
Type: single-piece replacement cutting blade for push or ride-on mowers
Cutting edge: ground and sharpened for immediate use
How to use
Before working on the mower, disconnect the spark plug or remove the battery to prevent accidental startup. Raise and secure the mower to access the blade area safely. Remove the blade retaining bolt(s), note the blade orientation, and take off the old blade. Fit the replacement blade in the same orientation, ensuring it seats correctly on the mounting hub. Torque the retaining bolt(s) to the manufacturer's specified value and verify the blade rotates freely without interference before returning the mower to service.
Usage recommendations
Use the replacement blade for regular maintenance cycles and inspect the blade after each severe impact; sharpen or replace again when the edge is beyond repair. Balance the blade after installation if vibration is detected and follow Scheppach's safety instructions for blade handling and torque specifications.
