I will be changing out my box, rear blade, and a homemade weight rack constantly as I clean up 14 wooded acres and build up a long driveway. I think a 3PH quick attach will help greatly. Am I right in thinking an I-match style (3 hooks) will be more useful than the one advertised on TBN (2 hooks on lower arms only)? From searching the I-net, the Land-Pride and Homier models look identical, but Homier is $99 (online) and LP is $300 (@ dealer)- is the Homier a good unit? I would want the adjustable top hook so that rules out trying to use a JD I-match on my NH TC33DA. Thanks for advice - Buckee

The distance between pins on your existing implements is VERY important to selecting the TYPE of quick hitch hardware you eventually purchase. Remember that a fixed three point type like Homier's can only pick up implements with lift pin spacings around 26 inches. I've got implements with pins spread between 22.5" and 33", which makes a fixed 3 point type impractical for my use. I found the bracket that Homier calls their "floating toplink" to be pretty useless. I bought about $50 bucks worth of LandPride floating toplink hardware to replace it.

A lift-arm-only system like Pat's solves both problems, but then presents one of it's own. By being pinned to the swivel balls, you're still left with a fixed angle of attack between the lift system and the pin. So even a system like Pat's has to be manually re-adjusted to compensate. After using my rake (22.5" pin spacing), I have to almost reinstall Pat's to be able to pick up the box blade (33" pin spacing).

With Pat's, doing this is inconvenient. With the Homier type, I couldn't pick up either one.

Just so you know what the specs are for these.

I looked up the specs on Cat I 3 pt in designing the drawbar top link for the Cat 1 drawbar I bought at TSC. The standard distance between the draft arms for Cat I is 26". The distance from center line of draft arm pins to center line of top link attachment point is 15". A Cat I top link at TSC is 1 3/4" wide and has a 3/4" pin. The Cat I bottom pin is 7/8".

IMatch, for instance, has the hooks designed for Cat II. You have to use Cat I to II bushings for the hook to fit tightly.

The Qh is great if you get implements that conform to the standard. Otherwise PAts system would be better.

I have a Land Pride QH & I really do like it. A little crude in some places, but overall not bad. It works well & hasn't broken yet.

Just remember that with any QH you are changing the one standard that no one has talked about: the PTO-to-3-pt. relationship. Yes, there is a standard to that, too. Most tractors are fine, but a lot of Kubotas & a couple of the NH tractors are beyond the limit from factory. Why??

Never heard of such a standard, so it would be great if you could quote your source.

There have to be at least a half dozen PTO shaft lengths in every farm store I've shopped in. Plus different spline diameters, tooth count, clutch design, et cetera. It's also why new PTO driven implements usually come WITH their own PTO drive shaft. There IS no such thing as "one size fits all".

As far as length goes, when buying a replacement I select the one most closely matching the minimum distance between the tractor PTO spline and the implement transmission spline. Longer than that, and you'll bend/break/crush something during TPH travel. Any fine tuning is accomplished with a hack saw. I've gotten lazy, and have cut down recent shafts with a reciprocating saw. A band saw would be best, but they're harder to justify in the budget.

Anyway. Quick Connect devices necessarily lengthen the distance from the PTO spline to the end of the lift arms. That distance is equal to the additional length you'll need on the PTO shaft to compensate.

Perhaps I should explain that ASAE calls out a range of possible PTO stub shaft positions. This makes it far easier for the manufacturers to supply the right PTO shaft assembly with their implements to fit a variety of tractors. Unfortunately, thers still isn't a one-size-fits-all for PTO. You may be aware that within a specific PTO profile style (i.e. Ov1) the better manufacturers (Bondioli & Pavesi, GKN Walterscheid, etc.) also offer differing heat treatment levels to increase strength/wear characteristics. This is handy if you are on the limit of recommended overlap & want to add a QH. Trust me, you won't be cutting that tubing with a sawzall or a hacksaw! I've tried. /forums/images/graemlins/smirk.gif
