ok i bought this tractor a couple months ago, it started up right away and ran great, i used it at home and it ran great. it sat a couple weeks i went to start it the battery was weak so it only turned over slowly for about 2 revs. so i turned key off and left it. i took the battery charger out a week later to boost it, as soon as i hooked up the booster i heard a pop! so after much review im stumped. when i hook battery up i hear starter (or something in that area) humming, so im gonna order a new starter cylenoid now and see if that helps. im just wondering if anyone else has had issue like this.
