19 . A method of making a bumper mount for a tracked vehicle having a longitudinal axis, a transverse axis, and a vertical axis, a forward portion of the tracked vehicle having a frame and a bumper, the method comprising:
forming a first, generally transverse, channel for engagement with a generally transverse tracked vehicle frame member, the first channel closely engaging at least two sides of the transverse tracked vehicle snowmobile frame member;
forming a second, generally vertical, channel for engagement with a generally vertical tracked vehicle frame member, the second channel closely engaging at least two sides of the generally vertical tracked vehicle frame member; and
forming a ribbed structural region for extending between the channels and the bumper;
forming a space within the bumper mount for a latch assembly, the latch assembly comprising:
a base;
a pin supported by the base and configured to releasably engage a stud of an upper body component of the tracked vehicle;
an actuator rotatably supported by the base and operatively coupled to the pin; and
a knob coupled to the actuator and configured to be turned to rotate the actuator and thereby displace the pin to release the stud.
20 . The method of claim 19 , the latch assembly further comprising a cover, and the method further comprising receiving a stud of an upper body component of the tracked vehicle into a funnel-shaped provision of the cover such that the stud is guided into a channel of the latch assmebly.
21 . The method of claim 19 , further comprising engaging the pin with a groove of the stud to retain the upper body component relative to the frame.
22 . The method of claim 19 , wherein the actuator is rotated between about 10 degrees and about 15 degrees by turning the knob, and wherein one or more stop features limit rotation of the knob to prevent rotation beyond that used to disengage the stud.
