Abstract: An add-on trailer is provided with a computer control system for automatically or semi-automatically monitoring and controlling the load equalizing function and preferably other functions of the add-on trailer. Display and control software is loaded into a portable computer such as a tablet or personal digital assistant (PDA), with wireless connection to the computer control system in the add-on trailer, such that the computer control system can be operated remotely.

Abstract: A floor covering removal apparatus and method are provided. The apparatus includes a frame for supporting the apparatus and a pair of interlocking gears which selectively and controllably feed a desired width of floor covering through the apparatus. One of the gears is driven by a drive which causes the apparatus to displace over a floor surface as the floor covering is fed through the apparatus. Cutting blades are mounted to the frame which cut the floor covering prior to engaging with the interlocking gears. A locking handle is provided to positively lock the floor covering between the interlocking gears prior to displacement of the apparatus along the floor surface. A control assembly enables an operator to selectively control the direction in which the apparatus is displaced.
