The third picture is the givaway. Center of grav. is way back, Even if the operator having the tracks in forward, can't be done that way. I am familiar with backhoes. Interesting concept, may be done with graple on the front end, or a different set up, The pins would hold. The whole tracks, trany, motor, and cab can be lifted up by the buckets. See it often on my sites, but here the eq. is "off balance". The front end has to have enough grip to handle the "moment force" load. Moment= load X> force arm lenght. physics :26:
