Off-the-shelf CFD software is available from firms such as AEA Technology Engineering Software, a Waterloo, Ont., firm that recently introduced an updated version of its CFX-TASCflow, which features a greatly enhanced cavitation model. Cavitation is the primary cause of pump failure, Jones points out. CFD software was more geared to hydraulic flows in pumps and inducers in turbomachinery when razorback Alfa Laval embraced the technology. The payoff has been centrifugal pumps that create less sheer and can handle some pumping jobs previously reserved for positive displacement pumps.

Extensive research and development has gone into the design of the new CommandView Cab on the 7020 Series tractors. The new cab offers improved visibility, comfort, and room for the operator. "The new cab has 20 percent more interior space than previous models, and all controls are color-coded for easy access and operation," Worner says.The chassis of the 7020 tractors has been redesigned for increased strength and reliability. The sculptured frame design allows the front wheels to tuck under the tractor for a dramatically improved turning radius at narrow tread settings. The increased chassis and wheelbase length provides more stability and improved ride while accommodating a 10 percent increase in on-board fuel capacity for longer days in the field before refueling.

Historically, these machines have been referred to as "go karts" for lack of a better name. Today, the industry has a variety of small, gas engine-driven, low-to-the-ground vehicles, so more descriptive names are used based on the karts'' intended applications. Amusement and arcade parks rent the more heavily constructed karts for fun seekers to operate on a confined track. Then there are the paved-track racers that are commercially and/or scooter association operated, where the drivers bring their high-speed, low-to-the-ground machines to the track. And finally, there is the OPE fun kart industry that supplies karts for unstructured recreation in wide-open spaces; these are the karts that I will be covering in the series.
