A crop sprayer includes a chassis, and a lift frame secured to the chassis, the lift frame having a left boom support and a right boom support. The crop sprayer includes a boom frame having a left boom support contact member and a right boom support contact member, wherein the boom frame is movable between (i) a first vertical position relative to the lift frame, and (ii) a second vertical position relative to the lift frame, and wherein the second vertical position is located at a height vertically above the first vertical position. The crop sprayer further includes a lift cylinder operable to move the boom frame in relation to the lift frame between the first vertical position and the second vertical position. The left boom support, the right boom support, the left boom support contact member, and the right boom support contact member are each spaced apart from the lift cylinder. When the boom frame is located at the first vertical position (i) the left boom support contact member rests on the left boom support, and (ii) the right boom support contact member rests on the right boom support, whereby the boom frame is able to be supported and maintained at the first vertical position without assistance of the lift cylinder. A method of supporting a boom frame of a crop sprayer is also disclosed.
