grace manufacturing products are good stuff. I haven't tried their mower but they had the best customer service I have ever had on heavy attachments. I've told this story before but when my shear was a few months old, the blade bolts failed on a hard tree causing the fulcrum effect that bent the massive pins. I dropped it off at Bobcat on a Friday (the distributor). Grace Mfg. had a truck at Bobcat in San Antonio Monday morning, shipped it to Missouri to their factory, repaired and repainted the shear, and shipped it back. I got it back on Thursday or Friday. I was absolutely astonished and amazed. They didn't swap mine out.. they repaired it! If that is any indication of the quality controls at Grace, that mower is a good investment.
