Bought the JS40 3 years ago. I have had this mower serviced more than any other I have owned. 1st Season was fine, Second Season was repaired 3 times; Self propel once, starting twice, third season had to replace carburettor since replace was cheaper than diagnosis and repair. Started great for three weeks then became unreliable, John Deere dealer no help. Season four dtarts by the 6th pull the first time, once warm if you need to restart need to wait 20 minutes before attempting restart. I was fooled by the name that this was a quality machine when in fact it is an MTD mower in green paint. I am always willing to pay more for a quality product, this time I was fooled. Never again!
