The wheelbarrow leveling system generally includes an outer leg having an outer leg mount adapted to be secured to a wheelbarrow. An inner leg is slidably positioned within the outer leg such that it may be extended and/or retracted within the outer leg to different heights. A trigger is provided which, upon being engaged or disengaged, will cause a locking member to engage with or disengage with one of a plurality of apertures positioned on the inner leg, thus allowing the overall height of the present invention to be easily adjusted to level a wheelbarrow. ## Claims ### Claim 1 A leveling wheelbarrow leg, comprising: an outer leg, said outer leg including an outer leg mount adapted to be secured to a wheelbarrow; an inner leg slidably positioned within said outer leg, said inner leg including a plurality of apertures extending along a length of said inner leg; a locking member pivotally secured alongside said outer leg, said locking member including a locking pin for engaging with one of said apertures of said inner leg; and a trigger extending through said outer leg and secured to said locking member for pivoting said locking member, wherein said trigger includes a finger grasp. ### Claim 2 (depends on 1) The leveling wheelbarrow leg of claim 1, wherein said outer leg includes a pivot retainer, wherein said locking member is positioned within said pivot retainer. ### Claim 3 (depends on 2) The leveling wheelbarrow leg of claim 2, further comprising a pivot pin extending through said pivot retainer and said locking member. ### Claim 4 (depends on 1) The leveling wheelbarrow leg of claim 1, further comprising a bias member positioned around said trigger. ### Claim 5 (depends on 1) The leveling wheelbarrow leg of claim 1, further comprising a stopper member extending through said trigger. ### Claim 6 (depends on 1) The leveling wheelbarrow leg of claim 1, further comprising a trigger mount for securing said trigger to said wheelbarrow. ### Claim 7 (depends on 1) The leveling wheelbarrow leg of claim 1, further comprising an inner leg retainer linking said inner leg with said outer leg. ### Claim 8 (depends on 1) The leveling wheelbarrow leg of claim 1, wherein said inner leg includes a base positioned at a lower end of said inner leg. ### Claim 9 A leveling wheelbarrow leg, comprising: an outer leg, said outer leg including an outer leg mount adapted to be secured to a wheelbarrow, wherein said outer leg is hollow and includes a lower opening; an inner leg slidably positioned within said outer leg, said inner leg including a plurality of apertures extending along a length of said inner leg; an inner leg retainer linking said inner leg with said outer leg; a locking member pivotally secured alongside said outer leg, said locking member including a locking pin for engaging with one of said apertures of said inner leg; and a trigger extending through said outer leg and secured to said locking member for pivoting said locking member, wherein said outer leg includes a pivot retainer, wherein said locking member is positioned within said pivot retainer. ### Claim 10 (depends on 9) The leveling wheelbarrow leg of claim 9, further comprising a pivot pin extending through said pivot retainer and said locking member. ### Claim 11 (depends on 9) The leveling wheelbarrow leg of claim 9, wherein said trigger includes a finger grasp. ### Claim 12 (depends on 9) The leveling wheelbarrow leg of claim 9, further comprising a bias member positioned around said trigger. ### Claim 13 (depends on 12) The leveling wheelbarrow leg of claim 12, wherein said bias member is comprised of a spring. ### Claim 14 (depends on 9) The leveling wheelbarrow leg of claim 9, further comprising a stopper member extending through said trigger. ### Claim 15 (depends on 9) The leveling wheelbarrow leg of claim 9, further comprising a trigger mount for securing said trigger to said wheelbarrow. ### Claim 16 (depends on 15) The leveling wheelbarrow leg of claim 15, wherein said trigger mount is comprised of a horizontal portion and a vertical portion. ### Claim 17 (depends on 9) The leveling wheelbarrow leg of claim 9, wherein said inner leg includes a base positioned at a lower end of said inner leg. ### Claim 18 A leveling wheelbarrow leg, comprising: an outer leg, said outer leg including an outer leg mount adapted to be secured to a wheelbarrow; an inner leg slidably positioned within said outer leg, said inner leg including a plurality of apertures extending along a length of said inner leg; a locking member pivotally secured alongside said outer leg, said locking member including a locking pin for engaging with one of said apertures of said inner leg; a trigger extending through said outer leg and secured to said locking member for pivoting said locking member; and a bias member positioned around said trigger.
