I have side-by-side pedals that I really like. I have a bad back as a result from breaking my back, and while I'm very thankful that I can still bend over and feel my toes, I don't twist well. Imagine now running a rotary cutter where the operator frequently goes forward and backward and is turned to the right so as to be able to see rearward with this shuttle shift?
The side-by-side pedals are much better on the floor, as is having the the PTO switch mounted on the righthand side console or B pillar like how Deere and Kioti do it.
Here is a video of me running a rotary cutter. You can see how often I change directions through the glass. As you watch, you can see how I'm running the steering wheel with my left hand, while off camera operating the top tilt remote valve as feel as the three point lift. While i could also shift with my left hand, it would not be as easy as the set-up I have with side-by-side HST pedals.
nice video and explanation.
the old ford 555c industrial unit i have. shuttle shift, 4 speed, has 3 clutch buttons, 1 on FEL joystick, 1 on shuttle shift, 1 on gear shifter. and then split brakes on left feet, and throttle pedal on right foot.
i tend to dump the clutch via FEL joystick, when wanting to operate FEL quickly. it really does speed things up in raising the FEL with a full bucket of dirt.
i also tend to keep throttle pedal pressed down between 25% to 100% when working the shuttle shift. ya i might rock the tractor forwards/backwards when doing this. and i would imagine sudden quick change in direction is hard on the mechaical stuff (gears, and like) but it keeps me moving quicker. and i just flip a switch, normally with pinky finger on left hand, as rest of left hand is holding onto steering wheel. but the shuttle lever is also right there, just barely enough room with gloves on, to not hit the shuttle shift lever when left hand is fully on the steering wheel.
but both above, after reading your post / watching the video. i can see how change in direction via a single right pedal could be handy for regular folks, and less wear on machine. above is more for like a wheel loader setup. were ya using unit to load dirt/sand into back of a dump truck / truck bed. vs a agricultural tractor in the SCUT / CUT range. were end users, are not wanting as much jerkyness of above. and the few hours on the machine if that a day. vs a day job were person is in the machine 7 hour so hours a day running the machine non stop.
============
side tracking, is there a SCUT / CUT tractor out there, that uses more of skid steer / zero turn mower setup with a combo lever / joystick one for each hand. were there is no steering wheel? kinda moving all the stuff (3pt hitch levers / rear remotes levers, along with FEL, steering, etc.. into the 2 joysticks. vs needing to move arms/hands all over the place.
