Need Help With Hole Spacing On 3-point Stabilizers Please.

[npalen]

I'm planning to build a pair of telescoping side stabilizers for the 3-point lift arms on my Kubota B9200. These will be replacing the turnbuckle type which are difficult to adjust due to space constraints.

Planning to space the holes in the internal member by 1/4" less than those in the external member (or viceversa) to allow 1/4" adjustment increments.

What I don't understand is the slot in the external member I see on some of the factory stabilizers. I do understand that some slack can be a good thing at times but wondering about the placement of the slot.

Someone can hopefully explain the positioning of the slot in relation to the rest of the holes.

I don't think it matters exactly where the slot is located. It allows for more side movement when using ground penetrating implements, by just moving the pin.

Any idea what's going on here? Almost looks like a threaded combined with a pin type adjustment.

Mark Hodge makes great stabilizers for tractors. you might want to contact him and ask for advice.

If you use two different hole spacings,,
you will be able to get adjustments of far less than 1/4" per pin move.

Example (I ain't saying this is right)
On the exterior part, use 1" spacing
On the interior part, use 3/4" spacing.
Adjust to where you want it, then select the holes that happen to line up!!:thumbsup:

I have had my tractor since 1995,, I have never adjusted them
so I could care less if they were welded.

I doubt they have been moved in the 35+ years life of the tractor,,
at least, they do not look to have ever been adjusted,,,

Below is probably the worst system EVER devised,,
inside the arms, turnbuckle chains.

A chain has to be un-pinned, and removed,,, to remove an attachment,,
or, the arms must be left VERY loose,,, :confused2:

I've been visiting with Mark and, while very kind and helpful, he doesn't offer stabilizers for the B8200 and B9200 Kubota. These models use outboard turnbuckles and space doesn't allow for conventional telescoping type. The design I'm working on would be unconventional even without the space limitation. Conventional just isn't much fun for me.
Now I just need to figure out how to incorporate the slots in this limited space to allow for a bit of "float".
I'm looking forward to being able to easily pin the lift arms all the way out for backing up to and attaching an implement. I know that a quick hitch would be easier but just not willing to live with the drawbacks. Lift capacity is already limited on the older "B" series and not all my attachments are compatible.

I wonder if the telescoping stabilizers on the B2301/2601, though they are inboard, could be modified?

The L3200/3800/2501/3301/3901 telescoping stabilizers (available from Kubota Wholegoods catalog) are outboard and could be an option too, but might be too large for your B9200. I don't have a feel for the B9200 3-pt hitch size. At least on the newer Kubotas, the 3-pt hitch on the larger B models is similar in size to the small L models, so there is a little overlap.

Here's the only photo I could find of my L stabilizers:

The problem on the B8200/B9200 Kubota with their wide tire/narrow stance is that the CAT1 lift arms end up against the tires in their outermost position. To overcome that, the point at which the stabilizers attach to the arms is moved forward to in front of where the vertical links connect to the lift arms.
This results in the stabilizers being extremely short at about 9 1/2" fully collapsed.

Interested in what you come up with. My L2800 telescoping stabilizers have SO much play in them (how they attach to the tractor) that I gave up trying to keep things tight.

I started to build a set (didn't know how to weld at the time) and I still have all the parts I made... Has me thinking, I need to finish building it! I did not have a "slot" in it. If I ever did need to snug something down I could always put one of the turnbuckles back on.

Nelson:
Here's a somewhat different way to do stabilizers. It makes a 3 point into a self centering hitch. This is on my B7500 but was copied from an IH 686. The orange center bracket pivots depending on the width of the arms to keep them centered.
