Quick Hitches: highly recommended.
Harbor Freight's is cheapest (especially with 20% coupon), and indistinguishable from the one at Tractor Supply. Both are about the same as Deere's more expensive I-Match but I suppose the I-match can be used on greater hp tractors.
1). You can back up to an implement such as a box blade or disc and shove it around until it lines up, contrasted to muscling the implement into alignment with a BF bar - after the implement has been parked a while and started to sink into the ground. For that alone its worthwhile.
2). It's a time - and back - saver every time you mount an implement. Even mounting a trailer ball - just drop the side to side towbar with ball attached, into the hooks, instead of spreading the tractor's arms apart to put pins into sockets.
3). I've used mine as the basic chassis for some welding projects. Here's a mockup starting to build a toolbar to pull a spike harrow. (there will be short chains from this bar back to the harrow). And I built it so that the harrow can now be lifted. The QH serves as the structure for the pinned-on lifting 'winch'.
Total cost $100 for the spike harrow plus scrap on hand.
Rear forks I fabricated.
'Po Boy Ballast Box' assembled in 2 minutes from materials on hand.
Note implements come in all sorts of random widths. There is a 'Standard' for a QH but expect to make minor improvements to your implements to match your QH.
Photo - I shimmed the pins on this little disc to match the width of the HF QH.
And finally
one of the many QH threads. The last post in that thread has a photo of the upper link adapter ($18) you might need for some implements that are built in a way that obstructs the QH's top hook.
In summary, just do it. You'll wonder how you got by without it.
If you look at that You-tube comparison HF / I-Match, be sure to look at some of the other vids too. That vid favors the Deere version but I think for a lower-hp tractor, the HF one at a third the price is a better buy. Update - I looked at several of those vids, didn't find one that I would recommend. Don't bother.
