Waxing,which means you washed it too,,,,well,theres your problem,,these chinese tractors were never meant to be washed,let alone waxed,,,you probably got water in the starter and it froze up,,,
after it thaws out this spring,find a nice muddy spot and run it around in it,,,throw a few hand fulls on spots that need it too,,,,than grease it,,put 10 times more grease on outside of fitting than on inside and smear it around a little,,pour at least 1 gal to much desil fuel in it and let it run down over dash and floor area,,change oil and spill about a pt. around over top of motor,,dab it up a little[smear] with oilly rag,,,get you a sheading very old snotty cat to sleep in seat,,,,throw several buckets of grass chaff around on areas and let it stick to the oil and grease,,along with several handfulls of twigs,,,,,
Than,never ever wash it again,,and never try starting it when it is colder than 20 degrees out,,may have to get a new battery too,,,by doing all this,you should never have a starting problem again,,,thingy
