Grasshopper mower PTO switch doesn’t activate deck

Hey Everybody,

I purchased my Grasshopper 329B around the end of October, and made sure I regularly serviced the engine as recommended in the manual. However, the PTO switch has become redundant since yesterday, and I’m unable to activate the blades – is this a serious issue?


Hello Gabriel,

Since you’ve mentioned that you regularly maintain your mower, I won’t ask you to inspect for basic component damage – I suggest you check the clutch and try to adjust it. Clutch replacement may be necessary based on your mowing conditions and doesn’t fall under regular maintenance requirements. This is most often the issue when there’s something hindering the PTO system.
