Went out to plow with the 739 this afternoon. It was 10 F. Had to pull the starter about 6-8 times to get the tractor started. Hadn't run it in about a month. Once running it seemed like it just never warmed up. Tended to stall when it came off idle from not being warm. If I ran it at higher rpm's for a while it warmed up a little and no problems. But if it idled for any time, it cooled off and tended to stall again. I'm using 5w-30 now. I wonder if I should switch to 0w-30 or 5w-20?
