If you're picking and placing construction materials, pallets or unstable loads like scrap cars with a forklift attachment, dial it back to a low response rate or use the fine mode adjustment that allows for finer modulation of the joystick as well s the output to the lift arms. Pile engagement Another addition to the modes built into the latest software will give the machine a torque converter feel relative to pile engagement, Britton says. "Torque converter machines have a natu- ral feel when you stick the bucket in the pile--it will roll itself back. We have programmed that feel into our hydrostatic transmission and get improved pile engage- ment when operating in TC mode." Caterpillar originally launched the 938K hydrostats with a computer system that required a dealer tech- nician to come out and reprogram the various modes and options for you. As of late last year, however, they have configured the system to be operator programmed through the in-cab monitor. And all these changes are backward compatible with the first 938K. What makes the programmable hydraulic response and hystat drive in the 938K revolutionary is that all these changes are made with soft- ware flashes. "There have been no physical, mechanical changes to the pump structure or the hydrostatic system itself," Britton says. These changes are made in software rather than steel, which opens up a wide range of opportunities. All these new features are cus- tomer driven, the idea for the ice mode came from customers push- ing snow in the winter but running landscape or construction crews in the summer, Britton says. Rather than have customers buy one wheel loader for snow plowing and anoth- er wheel loader for pile work and dirt moving, programmable soft- ware enables customers do to both with one machine and no compro- mises or tradeoffs in performance on any application.
