Down souf I believe they used series landys to drive farm machines and you could walk behind your landy whilst it was doing whatever, a one man job.
Also good for driving a saw or whatever
yeah its the hand throttle, mine have them, yer can use it to adjust the tick over of the engine or if yer running a PTO for a saw or log splitter in high tickover, to save you holding the pedal down its more even running too, or like i have , stick it in low box, get out and walk down the side of it when yer in the middle if no where, in effect its a tractor, use it as its intended
ooh, dont use yer hand throt on the high way ! its not cruise controll !
