The Original Lock Springs Rver Rat | The old 7720's were good machines but not nearly as durable as the new models. I have owned at least three or four 9600's,a 9610,a 9650 walker ,a couple 9750 sts,and a 9760. What kind of abuse are you giving these machines? Rocks are the only thing I can think of that would cause you so much trouble,luckily rocks are scarce on our farms. |
