ABSTRACT:
The invention provides material handling apparatus in the form of a lift arm assembly integratable with or releasably applicable to farm tractors or like relatively small, lightweight vehicles for front end loading and leveling having extended outreach capabilities. An extensible carriage which mounts stably and for guided reciprocable movement on the lift arms carries a material engaging device so interrelated as to enable an advantageous application of forces therethrough, both to break material free from a mass at ground level and to reorient the placement of material at elevated levels. In certain embodiments the material engaging device is tiltable in response and/or correspondence with movements of the carriage. In a preferred from of embodiment of the invention, a guided movement of the material engaging device and the outreach and tilting thereof is sensitively controlled by separate connectors extending thereto from both the lift arms and the carriage.
