Routine maintenance shouldn’t slow you down. 🛑✋️

With the PowerFold deck from Grasshopper, maintaining your mower is quick and hassle-free. In seconds, the deck folds up to give you easy access to cleaning, blade changes, and inspections—no tools, no heavy lifting, and no wasted time.
Even better? PowerFold is standard on every Grasshopper FrontMount because smarter design means less downtime and more time getting the job done.
