I am looking to buy a 48" Tiger cub or 48" Exmark Hp model. Considering the 19 Kawasaki engine. The mower will also have a spindle driven rear catching system. Is the 19 Kawasaki able to power the machine and catcher. One dealer says that it can. The tourque on the 19 Kawasaki looks high on the comparison graphs that are out there. Cost is a concern, yet I do not want to make a poor investment. Please advise if you have had experiences with the 19 Kawasaki and the catcher system.
