A U-shaped handle is physically attached to the back of a deflector atop a snow directing chute on a snowthrower. The deflector pivots atop the chute to adjust the trajectory of a stream of snow being thrown by the snowthrower. The handle is gripped and moved up and down to effect a pivotal adjustment of the deflector. A pivotal latch is carried on the handle which latch protrudes into the open interior hand grip space of the handle. The latch is spring biased so that a detent on the latch engages with a toothed rack with the interengagement between the detent and the rack holding the deflector in an adjusted position. When the operator grips the handle and squeezes the fingers of the gripping hand closed, the latch is pivoted to remove the detent from the rack and thereby permit pivotal adjustment of the deflector.
