Purple Tractor can plow an area of up to 2x2 plots at the cost of 4 fuel, or 1 fuel per plot. This Tractor is useful for farmers who have large fields, as it can plow them at a much faster rate. It can also be upgraded to plow a larger area using the Garage feature.
Note that the Purple Tractor functions in the same manner as a Red and Pink Tractors but is different in color.
The Purple Tractor can be stored in the the Garage system. Items in this storage building do not grow, and cannot be harvested, however they can still be used on the farm. Items in a Garage can be upgraded using Vehicle Parts.
