I have a velke on my 36" toro WB, and I love the concept, hate the velky. On rough ground it will twist and beat the heck out of you. If all you do is smooth yards though, it should work well.
Otherwise look at the bull rider type that has rotating castors instead of a multi link/multi axis pivot like the velke.
Velke DOES fold up very very nicely though, so def a plus for trailering.
