I'm here and I've just mounted and experimented with the HarborFreight QuickAttach 3pt hitch.
The unit is solid built and well worht the $70. The width issue (needing the stretch the lower mounts a 1/2" with a jack) hasn't been needed. I have had to pay particular attention to the implement lower pin to top pin dimensions though. What I've been doing with each implement is to make sure the measuremet is the same so as not to have to adjust the top hook on the adapter for each implement. Also the space between the top ears of the implement top bracket needs to be approxiamately 3", the top hook adjustment bracket and mounting bolts get in the way, widthwise. I think the Quick Hitch will be worh it but it does come at a price by having to modify some or all the implements that will be attached. If this does not suit you then look at the Pat's system as I don't think you would have as many issue's with bottom pins to top pin dimensions. That's my review of the HF quickHitch. bjr
