Claim:
A breakaway hinge between a first section and a second section of a boom for an agricultural vehicle to allow the second section to move away from an obstruction, the breakaway hinge comprising: a first pivot member attached in constant mechanical connection to the first section at an angle α with respect to a vertical line; a second pivot member attached in constant mechanical connection to the second section at an angle θ with respect to the vertical line; a connecting member to hold the first pivot member with respect to the second pivot member so that the second section pivots on one of the first pivot member and the second pivot member and the other one of the first pivot member and the second pivot member remains fixed with respect to the one of the first pivot member and the second pivot member that pivots, wherein as the second section encounters the obstruction as the agricultural vehicle is moving in a forward motion the second section is moved upward and away from the obstruction at one of the angle α and the angle θ, and wherein as the second section encounters the obstruction as the agricultural sprayer-vehicle is moving in a reverse motion the second section is moved upward and away from the obstruction at one of the angle θ and the angle α.
