A HD4 without one is a full experience to run - somehow with brake pedals set close and the fact using just one foot to steer while using other to control throttle - well confusing is the results .
Seems my HD5G using hands on track clutch levers and L or R foot on brake , then left hand on main clutch - right hand on loader controls but - then also L or R hand on the track clutch - well least the 2-71 throttle stays the same WIDE OPEN as you play with levers and 2 pedals .
My HD5G / HD5B seems old school when looking at FD Power shift and pedal steer but least - foot pedals are set apart so it's easier - and another center pedal to stop all motion when depressed .

Life lesson: If you’re being chased by a lion, you’re on a horse, to the left of you is a giraffe and on the right is a unicorn, what do you do? You stop drinking and get off the carousel.

Well, coke I ran a caterpillar D6c four years and became used to accelerators, regardless of what I have to do with the left hand and the right always on the blade . It became second nature I have a harder time with a high throttle and trying to steer. I’d rather have a low throw in tight places I can throttle down and maneuver much better. I guess that’s what you get used to as long as we get the red job done.

That is where the newer machines come in - ease of operation and almost loss of thinking , and SKILL takes over in doing all the operations without having to think about the next operation .
It's like the wobble stick control of doing more than one operation when moving your hand - fwd / back and side to side all doing separate functions . Difference between 2 stick or 4 stick backhoe - and then someone comes up with a joystick and puts more controls on it .
Going to a excavator controls with joystick , along with foot control of motion then swing of full platform - GUESS RUNNING A HD4 was easy when just right foot slowed down engine enough to stall torque converter to bring machine to a stop or crawl
