He said that QH won't work on that
MOWER. As you say it mounts to the tractor just fine.
Whenever you buy a QH you must make sure the distance between the lower arms of the hitch will fit the pin width of the attachment(s) you're try to hook up. Some low priced QH's on Amazon are too narrow. Sometimes you can reverse the pins on the attachment, point them in instead of out, to compensate, but it's better to get the right QH. Be aware of the size of the pins that come on the attachment, Cat I, Cat II, or Cat III. Cat I pins are the smallest diameter. Attachments for your tractor should come with Cat I or Cat II pins. Cat III pins are for large equipment. Most QH's have Cat II slots. If your attachment has Cat I pins and your QH has Cat II slots you can get bushings to make it fit correctly, or replace the CAT I pins with Cat II pins on the attachment. The less slop the better.
You must also be sure the height from the lower pins to the top where the hook (clevis) connects is also correct. Most QH have adjustable top hooks that can be moved up and down in a series of holes, or removed altogether, to accommodate different attachments. The top hook on your QH is fixed in one spot and limits the type of attachments you might be able to connect. One more thing, on my Harbor Freight QH the top hook didn't stick out far enough to hook up so I had to buy another hook that did to make it work.
