i am thinking about opting for a 48" walk behind with sulky to replace my JD 525 front deck mower. I have been offered a price (before negotiations) of $2200 for a 48" Bobcat belt drive var. speed walk behind. I have heard some good stuff about Bobcats but have not heard anything that I know of regarding this model. It is mostly flat here so i think that a belt drive should suffice even with a sulky. What sulky (type / brand ) do y'all recommend?? This mower has a 15 HP Kohler eng and I am sure that this will catch some grief, but hey, that is why I am asking .
