Well, I have pretty much decided to get a Velke for my 48" Bob-Cat belt drive mower w/ 15HP Kawi engine. I just got back from my local power equipment dealer, and he let my demo the Velke single wheel, and the double wheel Velke. He said that most Lco's in my area prefer the Velke single wheel, and he stated that he thinks that the Velke single wheel is the better of the two types. I found that the single wheel was a little easier to maneuver (was on a new Metro) than the double wheel (was also on a new Metro). He quoted me $279.00 for the single wheel Velke, does that sound like a fair price? What do you think?
