Sorry for the dumb question but never mowed before and been thrown in the deep end this morning due to an illness. So I've hitched up the krone mower with the link arms set dead level and they remain level when the mower is folded up but when I put the mower into work position the right hand link arm is about 2 inches lower than the left meaning the frame of the mower isn't level either. Is this how it's supposed to be? Doesn't look right to me
