Mcculloch Ride On Lawn Mower

McCulloch ride on lawn mower has worked all season went out yesterday but for some apparent reason the motor would not start have checked the battery but not sure if this is the problem excellent grass cutting machine also comes with grass box and side cutting cuts and several levels forward gears and reverse gear no rust no holes no tears and see has done me proud since purchasing ideal if anybody has the knowledge or know how to get the lawn mower started unfortunately due to work commitments and hours of working I do not get chance to fix it
