Looking at purchasing a tow behind debris loader. Right now i see Billygoat, Scag, and Monster as top choices. I want something that will get the job done FAST yet be reliable for years to come. I also want a machine that can shred the leaves really well. and also a high cfm. Im considering the 35hp billygoat, 36hp monster, and the a scag 35hp or 48hp. The main difference i found were the impellors. billygoat and monster have teeth on theirs and scag has no teeth. is there much of a difference in the three of these regarding mulching of the leaves? I've never owned a loader before so please provide good feedback. thanks.
