Abstract
This Phase I effort will investigate the feasibility of basic concepts for a hillside straddle tractor. A true straddle tractor for tall crops on hillsides does not currently exist. This straddle tractor, the Smart Mountain Mule (SMM), will be designed as a tool for Christmas tree farms in hilly terrain. The ultimate goal of the researchers (through Phase II and beyond) is to design and build a safe tractor with four-wheel drive, four-wheel steering, and a smart tilting system, that is able to tilt its center of gravity to negotiate hillsides and straddle crops such as Christmas trees. The Phase I goal is to prepare preliminary designs for certain key subsystems, i.e. the steering and tilting systems, to build a scale model prototype of the tractor, and to perform a thorough safety analysis. The PI and researchers at TRDC will work with consultants to create a computer simulation of the tilting and steering systems of the mountain tractor. The principal investigator, a professional tree farmer and expert in the requirements of a tree-farming tractor, will create the scale model prototypes using the computer simulation as a guide. Since studies have shown that more than 70% of tractor roll-over injuries and deaths occur on slopes, safety analysis will be crucial in every step of the design.
