Claim:
A stabilising arrangement to support an object above four ground engaging means, the arrangement including an interconnection means interconnecting at least three lever parts including a first lever part, a second lever part and a third lever part, each of the lever parts includes a beam portion connected to the interconnection means by a respective pivot having a respective pivot axis, thereby providing respectively a first pivot axis, a second pivot axis and a third pivot axis, each ground engaging means being attached to or integral with one of said at least three lever parts where one of said four ground engaging means is connected to the first lever part, one other of said four ground engaging means is connected to the third lever part and at least one other of said four ground engaging means is connected to the second lever part, the interconnection means including a stem portion, the first pivot axis and the third pivot axis being at an angle of up to thirty degrees of parallel to each other, and within thirty degrees of perpendicular to the second pivot axis, the second lever part including first and second engaging regions, the first engaging region being located on the opposite side of the second pivot axis to the second engaging region in plan view, the first lever part including a first engaging region, in use engaged with the second engaging region of the second lever part, the third lever part including a second engaging region, in use engaged with the first engaging region of the second lever part, such that rotation of the first lever part drives a rotation of the second lever part which drives rotation of the third lever part in a substantially opposite direction to the first lever part to permit a warp displacement of the four ground engaging means, the stabilising arrangement thereby providing support of the object on uneven ground, and wherein the stabilising arrangement includes a travel limit limiting the rotation of each lever part about its pivot axis to thereby limit an articulation or warp displacement of the lever parts.
