Hi, thanks for the reply, I looked at yours as well, I don't know off-hand if the BC brand has a hydraulic scarifer. The deluxe version has a scarifer, but I can't see any hydraulic connections, so it could be a manual adjust.......... PeterI'm not sure how the current Bobcat one works, but the scarifier teeth on ours are controled from a cylinder and can be lifted and lowered from the operators seat. Check us out here.

Unfortunately I have never had a chance to use one, so I can't help you there.
Thanks
