Nice video. As the owner of an early ('79) B7100, it's interesting to see how many little differences there are between mine and these later hydro 7100s. The diff lock relocation makes sense given the HST pedal takes up all of the right floorboard, but I'm interested even in the throttle...on mine, pulling it towards the operator increases engine speed while throwing it away does the opposite. Shut-off is also accomplished by a yellow "trigger" beneath the dash; pull it and it shuts off fuel. Vive les differences!
