The apparatus ground speed can be locked by stepping on a step () pivoting a composite block () to engage with an engagement () of the transmission proportioner arm (). A gate () of the hopper () is opened utilizing a control lever () pivotally mounted to a pivotably mounted control block () to either engage or avoid a tang () of an adjustment guide (). A drive belt system includes a variator () having first and second sheaves () having variable effective diameters when their pivot pin () is moved by pivoting a lever (). A spray tip () sprays a fan style spray at a small acute angle to the application area. A flip shield () is pivoted about an axis parallel to the movement direction and includes a linear straight portion () parallel to the axis in a redirection position.
