A vehicle for displacing feed includes a frame with wheels having a plurality of elongate tread portions and grooves, a motor for moving the vehicle in a moving direction, and a material displacer to displace the material, when the vehicle moves in the moving direction, over the floor towards a first side with respect to said moving direction. At least a majority of the tread portions is arranged such that they extend, when in contact with the floor, in a direction that makes a sharp angle with the forward direction opposite said first side. Thus, diagonal tread portions are predominantly directed to one side to counteract a reaction force of the feed being displaced sidewardly by the vehicle.
