THis tractor has 3 PTO speeds, does anyone know what they are? I've been runnig the mower on 1, but it seems slow. Also, can someone tell me what the correct procedure is for starting this thing in cold weather? I had problems starting it even with the engine heater on. I tried everything and it would fire right off with starter fluid, but die after that burned up. After playiong under the hood a while I found a fuel dump valve??? When I opened the valve and started the tractor it started right up and fuel poured out of the valve. Was it just flooded and that dump valve cleared it? Do you normally give a diesel gas when trying to start it or leave the throttle closed all the way? Sorry for all the questions, but I have no manual and know nothing about tractors or diesels.
