I'm considering the Hustler Roll-On sulky. I know it's $399. Will it fit my other walkbehinds also? I'm using an Exmark TT and Bunton. I'd consider a Hustler if I like the sulky! Does the sulky flip up or chain up out of the way for trailering, etc? Is it a fixed or trailering type sulky? If it's trailering, does the sulky wiggle a lot from left to right as my trailering wheeled sulkies have done? Will it outstripe the Proslide sulky? And the main question is: How is the ride quality? I have a Proslide right now, it rides very smooth but there is a lot of maintenance to do on them which I think the Hustler sulky would avoid. How smooth is the Roll-On sulky? Smoother than the Proslide? Between the Proslide and a wheeled sulky? Or rougher than a wheeled sulky? I'm sure if you answer these questions for me here, it would assist others in their questions on the same sulky. I think I covered everything! Thanks!
