I spent a lot more on my Quick Hitch from
Land Pride. I had given thought to the Habor Freight unit till I watched a few you tubes. Nearly every one they said you had to modify or buy extra things to hook to all your equipment. The last one was one all bent out of wack when the fellow got stuck in the mud with a tool on the quick hitch.
The Land pride QH 15 hooked up nicely to my
L3301 Kubota. Came with bushiungs for the small size lift pins also. back up to my back blade and hooked the bottom pins. Removed the 2 pins from the top hook sliped it thru the back blade top pin and reinstalled those 2 pins with the hair pins.
Works the same way on the box blade, rear cultvator and brush hog. I did it the same way on the finish mower but the hook have to be hooked a lot higher on the QH so will probably made a mod to thre finish mower.
Best thing I see to do with a HF QH is to remove the bolts holding rhe top hook in place and buy removable pins that fit in their place.
Also since I can not see my hooks when backing up to a tool and line the pins to the hook I painted an arrow on the top of the QH as a line up mark.
