Claim 12:
13. An earth levelling blade assembly for use with a loader movable across ground in a forward working direction in which the loader includes lift arms, the assembly comprising:
a levelling blade having a front working face, a rear mounting face opposite the front working face, and a bottom cutting edge along a bottom of the levelling blade;
a first mounting frame arranged to be releasably attached onto the lift arms of the loader;
a second mounting frame fixedly attached to the rear mounting face of the levelling blade;
a coupling arrangement between the first and second mounting frames that (i) supports the second mounting frame to be freely pivotal about a forward axis relative to the first mounting frame in which the forward axis is oriented in the forward working direction of the loader and (ii) supports the second mounting frame to freely translate relative to the first mounting frame along a translating axis oriented perpendicularly to the bottom cutting edge of the levelling blade and perpendicularly to the forward axis.
