I just ordered one of these sulkies. Looks pretty good to me. yea $500 is alot but $350 for one that all the pivot points are shot in 4 months is alot of cash too. I actually modified a sulky a couple years ago using the tractor PTO u joints similar to the Kage. My engneering wasnt the greatest but I knew I was on the right track. I prefer the trailer type sulky over the caster wheel type because the caster wheel ones are too long in the corners and they dont track behind the mower. Outside wheel swings too wide and goes off the lawn into stuff. Like shrub bed, building, curbs ,etc..
We use only Hustler WB so keeping both hands on the controls is not an issue. Can operate with one hand easily.
