The guard unit for the cutter wheel of a stump removing machine has an upper member pivotally mounted on the machine for up and down pivotal movement, within defined limits, to maintain a shield member in a continuous covering clearance with the cutter wheel during a stump removal operation. A bottom member of the guard unit has a central portion and outwardly and upwardly inclined end portions. The central portion is rideable on the top surface of a stump during a cutting movement laterally of the stump and on a reversal of the lateral cutting movement an end portion is engageable with an edge portion of the top surface to position the central portion on the stump top surface.
