The kind used to bulldoze a house ... (I'm drawing a picture by the way) and I want to know how many levers a bulldozer driver would be handling
One lever to adjust the blade. Like a joy stick on the arm rest now days with a shifter in front of the seat. Old dozers had two hand clutches to disengage each track. a brake pedal for each track plus a shifter.
Four to six levers. One to move the big blade up and down, 1 to move the big blade side to side, and another to manipulate the blade to 'scoope up' or lie flat during the 'dozing'. 1 gear shifter. Tractors are great. Lots of options
