D17, better suited for Cat I, or Cat II?

CAT II

Thanks fellas! I figured that was the case, but wanted to make sure. There's a lot more misinformation readily available out on the "inter-web" than good info. Hence the reason I bug y'all with questions so often.
Thanks again!

If ya want to know anything about ALLIS. This is the place to be.

A lot depends on the weight of the tractor and the weight balance affected by the distance the implement is behind the rear wheels. Cat II implements tend to be bigger and heavier. You can't plant controlled when the front wheels are just barely touching the ground. You can't rotary how or cultivate either without the guidance from good front wheel contact. Been there, done that with a MF-135. Front end weighting was crucial, but I loaded up a 6 row JD cultivator and a 15' JD rotary hoe that way. I made the lift pins on my lathe for those. When I loaded my three point sprayer filled with 32% N and hitched my planter on the draw bar I had to find all the front weight I could hang on to plant with better control than the rear brakes and take out half the 32% which meant refreshing that tank every 2 acres.

In good farm stores there are cat I pins with cat II mounts. So it is practical to change the implements. And then there are sleeves or bushings to center cat 1 pins in cat II lift arms and top links. And there are double ended lift pins cat II on the fat end and cat I on the thin end so they can be mounted with the cat II pins outside the implement frame and cat I inside and be handy for both widths of lift arms. For examples of what is available, look at pages C2 through C4 of the catalog section C at Baum Hydraulics. www.baumhydraulics.com The prices are their suggested retail prices, they sell for less. Look for DATE on the page, the number following DATE is 100 times the trade discount in %, e.g. DATE 2000 means 20% discount on the price they sell for.

If the top link height on the tractor is shorter than the tower on the implement, the implement will tilt forward when raised which usually isn't a great problem. If the relation is reversed, lower on the implement then the  back of the implement won't lift as much as the front as it tilts back and that's often not so great.

Fundamentally the choice of implement hitch and implement choice has to depend on tractor front weight, tractor lift capability, and implement weight.

I like that setup. Just curious, (as this has been the only part I can't quite figure out) Where is the mount for the lower arms mounted? All the pics I find block where/how that part is mounted.

No offense Dave, but I have a couple of concerns with your set up.

With it bolted up where the drawbar hanger goes, the pull point is set up higher and further back which can affect the balance of the tractor (especially when plowing or heavy pulling).  I do not think that area was designed to be a pull point either (it only holds up the drawbar).

I think a setup that hooks directly to the snap coupler would be the best.  My dad made one 30 years ago - worked great and the traction booster was still able to function.

Different strokes for different folks -- makes the world go around - If it works for you, carry on.
