1. An autonomous robotic lawnmower comprising:
a driving unit comprising one or more drive wheels, and
a cutting unit arranged to cut grass when in a cutting position relative a ground surface,
wherein the lawnmower comprises a folding mechanism allowing the cutting unit to be pivoted relative the driving unit around a pivot axis from the cutting position to a pivoted position,
wherein the lawnmower comprises a locking mechanism arranged to, in a locked state, lock the cutting unit in the cutting position, and in an unlocked state, allow the cutting unit to be pivoted relative the driving unit,
and wherein the lawnmower comprises an actuator operably connected to the locking mechanism to control the locking mechanism between the locked state and the unlocked state, and
wherein the locking mechanism comprises an eccentric, and wherein the actuator is operably connected to the locking member via the eccentric.
