212 is adapted to receive the post 208 the receiver 212 is typically attached to the blade of a snowplow not shown in fig2 a and 2b the receiver 212 can also be attached to another part of the snowplow in one embodiment the receiver 212 can be removably attached to the snowplow allowing the receiver 212 to be moved on the snowplow in order to adjust the position of the target 200 the receiver may be integrally built into the snowplow or attached to the snowplow by welding on bolting on clamping on or other means in one embodiment the target 200 is permanently attached to the snowplow but can fold down or collapse out of the way when not in use as shown in fig2 a and 2b the receiver 212 includes a slot 220 adapted to receive a pin 216 in the post 208 as the post 208 is inserted into the receiver 212 the pin 216 mates with the slot 220 when the pin 216 is mated to the slot 220 the target 200 is securely mounted on the snowplow in one embodiment the post and receiver cross sections are not round so that when they mate correct target orientation is facilitated without the use of a pin and slot fig3 a shows a snowplow being installed on a vehicle using the snowplow attachment system fig3 b is a plan view of the illustration of fig3 a initially a snowplow 312 is attached to the vehicle 308 by conventional means such as by manually moving the snowplow 312 and aligning the attachment points of the snowplow 312 to the attachment points of the vehicle 308 and then connecting the snowplow 312 to the.
