I recommend the tomahawk older troy built models, I think they were better built and more heavy duty.
If you are a skilled mechanic and machinist, or know someone who is, I suppose it's possible to adapt equipment like this over to bcs pto style. Would need to make sure that belts are protecting the pto from getting jammed/abused. Anyway it'd be quite a job even for a pro, I'm sure.
Here's my assesment of a lot of attachments for BCS tractors. You can usually get a *used* device with a standalone engine that will do the job you want for like 2-400 bucks, vs buying a bcs attachment for 1000-2000 dollars. The bcs version is usually heavier duty, more capable. But it's always a constant temptation to cheap out and buy dedicated devices like chippers, snowblowers, wood splitters, etc. If you want to save some space and eliminate multiple engine maintenance headaches, you gotta pay quite a premium, but in fairness, the 2 wheel tractor implement is usually more capable/heavy duty. Sometimes I see bearcat or DR or some such powerful chippers with standalone engines, that are arguably as good or better than the BCS implement equivalent, and cheaper as well.
