I've been considering a disc hiller for the 184.
I have the 3-point hitch and also have a trailer mover with a 2" receiver.

This would cost more and have less features.

I like the two above, but the shipping cost is about $100. This one below has free shipping.

Anybody know of a better option? Used equipment is an option.
