Dual shadow mask design can overcome the size and resolution limitations of shadow masks to provide capacitor structures with small effective areas. The mowing vehicle is operative to form windrows of crop in one or more of three locations, namely, a central location passing longitudinally between the wheels of the vehicle and one on each side of the vehicle. The device can have a user-movable handle that is associated with an end-of-stroke feed-back means for providing a corresponding feed-back to a user actuating the handle. During engagement, the ball socket and the extension arm may provide tilt capability but thereby prevent any rotational movement relative to the hitch ball.
