Drawbar Pull Test Rig

Load Cells

Load cells and crane scales which are based on a Load Cell can be used to measure tractor pull. We'd like to prototype a 4-track, double-motor per track Cat D7 equivalent system, which totals 8*3600 lb or 28,800 lb of traction. See http://opensourceecology.org/wiki/Modular_Track_Unit_v18.01

Crane scale or load cell or hydraulic cylinder attached to a large tree trunk?
