Put in some seat time today, the tractor was running rough, engine stalling and quiting, restarted fine every time tho, I cked the fuel filter it was OK, no water, that was my first thought, bad fuel, the tractor as never run rich but thats what it was acting like. Got back to the barn after many stalls, thought to ck the air filter, it needed changing but nothing major, thats when I noticed something in the bottom of the canister, on closer look it was 5 pellets of dog food! That puzzled me for a minute, then I started digging, a rat/mouse had filled the breather tube up and it was completely blocked with dog food, my major problem was nothing more than a clogged air filter and busy mouse with a huge appetite
