The Vector autonomous tool carrier with mowing deck is (already fairly quickly) cheaper than a radio-controlled mowing machine. The rate at which the Vector pays for itself depends on several factors such as the size of the area to be mowed, the complexity of the terrain and the amount of mowing to be done.
An autonomous mowing machine will save on man-hours and fuel costs because it can operate autonomously without human intervention. This means there are no labor costs and less fuel is needed to operate the machine. It can also lead to increased productivity and efficiency, as the machine can continue to operate without breaks or fatigue.
