A lift arm assembly for a small or "mini" loader is pivotally mounted onto a self propelled frame for movement between a raised and a lowered position. In the raised position, a support strut is provided that fits over an extended rod of the lift arm operating cylinder and will prevent the lift arm assembly from lowering. The support strut is stored in a front tubular cross member of the lift arm assembly. Additionally, the front cross member supports an upright strut that acts as a back stop for material in a bucket, by projecting upwardly beyond the bucket top so that if an object in the bucket tends to roll rearwardly, if the bucket is not leveled, it will be intercepted by the upwardly projecting portion of the back stop and deflected laterally.

The accessory of claim 10 wherein the mounting arm comprises a pair of mounting arms, the pair of mounting arms being mountable directly to opposite sides of the track suspension. 12. The accessory of claim 11 wherein the pair of mounting arms are mountable to a rear idler wheel of the track suspension at an end portion of each of the pair of mounting arms. 13. The accessory of claim 12 wherein the pair of mounting arms are mountable to a track slide rail of the track suspension at a distal end portion of each of the pair of mounting arms and where the end portion and the distal end portion are spaced apart and thereby the pair of mounting arms are fixedly mountable relative to the track suspension. 14. The accessory of claim 10 wherein the mounting arm has a tubular cross-sectional dimension or a flat cross-sectional dimension. 15. The accessory of claim 10 wherein the snow collector/leveler has a flexible/resilient characteristic which allows a portion of the snow collector/leveler to pivot relative to a longitudinal axis of the mounting arm. 16. The accessory of claim 15 wherein the snow collector/leveler can pivot between a home position and a deflected position relative to a horizontal plane defined by a bottom surface of a track of the snowmobile. 17. The accessory of claim 16 wherein the snow collector/leveler has a memory characteristic which maintains the snow collector/leveler in the home position when the snow collector/leveler is not impacting at least the portion of the snow mound, the snow mogul or the snow displacement in the snow trail. 18. The accessory of claim 16 wherein the snow collector/leveler comprises an at least partially downward force when the snow collector/leveler is in the home position and when the snow collector/leveler is in the deflected position. 19. The accessory of claim 10 wherein the mounting arm is removably mounted to the track assembly. 20. A snow trail grooming accessory for use with an operating snowmobile to groom a snow trail during operation of the snowmobile, comprising: a snow collector/leveler mountable to the snowmobile, the snow collector/leveler comprising a tubular shell defining a temporary retention chamber therein which is adapted to receive snow from the operating snowmobile or the snow trail through at least one opening in communication with the temporary retention chamber and wherein the tubular shell is fixedly mounted for no axial rotation; and, the temporary retention chamber comprising a portion that is substantially bounded by a circumference of the tubular shell and the temporary retention chamber having a longitudinal axis wherein the temporary retention chamber is oriented in a non-parallel direction as defined by the longitudinal axis relative to a longitudinal axis of the snowmobile. 21. The accessory of claim 20 wherein the at least one opening is located in a front portion of the tubular shell opposing a track of the snowmobile when the snow collector/leveler is mounted to the snowmobile. 22. The accessory of claim 21 wherein the opening is located in an end of the tubular shell. 23. The accessory of claim 21 wherein the tubular shell comprises at least a second opening in communication with the temporary retention chamber and the second opening is located in an end of the tubular shell. 24. The accessory of claim 20 wherein the at least one opening is locat
