Does this seem right to you guy's? I had my Walker put in the shop cause it was smokeing bad (Rings right). Well a week and a half later I got my mower back and the next day I got the bill. They billed me for 20.3 hours labor ($883.00) parts were $250 almost $1200 for the repair. I was thinking it would run about $600 for the repair. Please, anyone does this sound right?
