i just fixed axle drive chain on friends tiller i borrowed and broke. what a piece! the drive chain broke becouse the sprocket is welded to the axle and the bushing they put in to hold the axle isnt long enough on one side so the axle forces the chain over and stressed it to sheer apart. it happens when you put weight on one tire and have it in gear,tipping it. to fix the problem you need to put spacers behind the tires to hold axle from walking back and forth. i used pieces of pipe with big washers on both ends. hope this helps
