After 3 times of having it the shop, and concerned I received a lemon(which was found later it was--A defect in the electrical) the GM Rich(fought for me with Gravely ) got me a brand new replacement mower straight from the factory. I would like to comment the entire staff for resolving this issue. 1. Rich GM 2. Chris the manager at Portsmouth 3. Jamie the mechanic 4. Ted-Sales i am very happy, and the new mower works excellent!

The employee opened the box to show me how it worked. An hour later I go to return it, and they would not, because the box, they opened, was opened and now I'm stuck with the wrong item. Not how you treat customers. Never going back. Should have looked at the other reviews as well. Crap business. And not a single mask in a single employee.

Charged me $40 right off the bat. Calls me and tells me what is wrong and I ask him to try and repair it. Says he will check on parts. Calls me back and says he can't get parts and the machine can't be repaired due to this. I told him I would just come and get it. I pick it up and spend 10 mins with it. The drive wasn't seized!!!!!! It was just stuck and needed to be greased. Ran old gas out of machine and put VP 4 cycle in and runs like a top with drive now working. Feels like they saw an older machine and didn't want to deal with it when they can just take the money from the deep pocketed town folks. Won't be going back. They should be ashamed of this. Will not recommend them for repairs or anything else for that matter. ZERO Stars rating( made me leave something)
