Mule 610 stalling while plowing snow.....

[Scott Meszaros]

Question for the group....i have a 2015 Mule 610..........been pretty reliable....250 hours on meter.....this past weekend, i was plowing snow..........yes, extremely cold, but i noticed that Mule ran fine when running around the neighborhood, but when i went to plow, especially when the snow was heavy,  when i would come to the end of a "push", the thing would stall out......started right back up with no issues......ran ok otherwise.................doesn't miss, doesn't backfire, idles fine otherwise.....any thoughts? thanks

first thing that comes to mind is fuel supply.  whens the last time you changed the filter?

thanks for responding...........that was my first thought, but fuel filter was changed sometime earlier this year..........i took it out again yesterday......plowed some snow, and ran around the property running thru 10 inches of snow............no issues......the only difference is the temp yesterday was about 25, no wind.................when i had the issues, it was -8, with 35 mph winds...............i did add some fuel dryer in between times.....is it possible that i had a small chunk of ice in the filter, that was causing the problem?........i always run with fuel stabilizer, but the fuel dryer was a new additive............

couple ideas, its fuel issue, could have ice crystals in fuel tank, throw some additive in the fuel second fuel pump, saw this several times pump seems to work but not to capacity required for loading high rpm motor

for information regarding the fuel pump, they go weak idle all day but full power they will not supply enough fuel to keep going, what I found Walmart sells the fuel pump for under 20 dollars, here I have to order on line keep a couple around, one in the glove box

we use our Mule fxt 820 to plow snow. It has been fine of the last two years. We have it serviced every spring. This year it started to cough and cug on the uphill part of the plowing. We would let it cool down then it would seem OK for a while. There is no way to get it off the mountain in the winter, so we started trouble shooting ourselves. We found that the vacuum holes had failed, so we replaced them. then we replaced the fuel filter. Those things did the trick It is running fine now.  We are disappointed that these things were not a part of the serve last spring, the service manual doesn't include these items as standard Maintenace, which I think is odd. By the way, we purchased the Service manual, which was very expensive. I used to write technical manuals before I retired. This manual it probably one of the worse I've seen., the layout is terrible. References between sections don't include page numbers and the titles are sketchy. Kawaski hire a professional writer. 

Anyway, if you are having problems with power or cugging, try the vacuum hoses and fuel filter.
