the main reason for a stand on unit is:
1) on and off use: these are not units that you're grading large areas with I will admit that but lets say you're making beds, mulching or even just augering some fence post its a one man job now becasue the operator can fill the role of helper and operator
2) visibility: no cab and a higher vantage point allow you to work in smaller areas without running over stuff/people
I'll give you an example my hardscape crew will 9/10 times go for the sk650 to move our large tamp (~600#) vs our 287b cat its just faster and easier to not have to climb in a cab
talked to my dealer today and will have a demo when convenient for him (i'm in no real rush) anyone interested in buying one of my current units?
