Yeah they are pretty fancy now.
The left handle controls direction and speed. Push it forward to go forward, use the thumb buttons to increase or decrease speed. Pull it all the way back to go backwards, the same thumb buttons controls speed in reverse too. Push it left or right to steer. Pushing it all the way left or right makes it counter-rotate.
The right handle controls the blade. Push it forward to lower blade, pull back to raise. Push it left or right to tilt. Use the thumb button to adjust the angle. There is also a button that automatically shakes the blade to help sticky dirt fall off.
The pedal on the floor is a two mode programable decelerator pedal. In one mode, it only decelerates the engine. The next mode slows the travel speed, but won't affect throttle unless you push it all the way in, so all the way in stops the machine and idles the engine.
There are also auto-throttle and traction control settings. All control sensitivity can be adjusted to your preference for the job. The blank spot in the dash is to add a computer monitor to control and monitor the auto-grade laser/gps system.
