V.I.P. very important part
Optional and accessories

Have you ever accidentally hit a stone with your lawn mower and damaged the crankshaft?

Being distraction or due to just bad luck, small “accidents” may happen, which may lead to damaging the lawnmower’s mechanics.

Grin has introduced a device called ENGINE PROTECTION CONE to minimise these risks.
