I have had Ferris since 2005 and I don't really have any issue with them. They last long (if you keep up on the maintenance) they cut great and they are relatively fast. I am considering buying a new mower within the next few months and I have had my eye on Scag. I will need a 61" walk behind mower. According to the specs, the Scag can go up to 7.4mph compared to the Ferris at 6mph. If it is faster and as durable (more durable I hear) it would be a no brainer for me. I would like feedback from people that have ran both the Ferris 61" comfort control DD and the Scag 61" Walk behind... new models only. I don't know if the comparison will be worth it for older models unless they haven't upgraded them much.
