Please Help,
I have a Kubota BX 23 with a Tebben (Rankin) 48" cutter but whenever I turn a corner it pops off the mount pins. Anyone have any pics of one hooked up or any advice?

Thanks,
Girl without much of a clue

Pjhilferty,

I just looked up a picture of the Tebben implements, as I've never seen one before now.

Since the Tebben hooks up to the tractor in exactly the same way as any other 3-point implement, I'm sure your problem is a simple one.

After placing the pins of the mower into your tractor's 3-point arms, you should then install a clip over the end of the pin, which prevents it the arm from sliding off of the implement. I'm assuming you don't have these clips installed.

These hitch clips can be found at any Tractor Supply, as well as most hardware stores. They cost about 30 cents each. You'll need three of them........one for each mounting point.

Unless I'm missing something here, I believe your problem can be solved for about one dollar.

Joel ....

I don't see any place to put the clip; and there isn't any place for pins? Down under the drive shaft where you attach the implement on the left and the right are just bars on each side with no pin holes? Not sure how to send pics? Thanks so much for your help! ....

Pjhilferty,

If I'm not mistaken, your mower has four wheels on it.......two in front, and two in the rear.

Provided that I'm correct regarding that, then your mower is what's called "Floating Three Point". This is a nice feature. It allows your tractor to go over slight hills and bumps, with no need for the operator to attempt to keep the mower on the ground.

The arms you see on the front of the mower are likely not complete. There should be two arms on the front of the mower, and these arms should have a linkage on the end of each of them. The linkage of the "U" type, and it should have two holes.....one on each side of the U arms.

Your lower 3 point arms would slip inside this U link, and the pin would go through the U...then through your tractor arm, then back out the other side of the U linkage on the mower.

Of course, you also have a top link pin.......making three pins total.

Your mower is designed to self-adjust to the terrain. Set your 3 point arms pretty low, so that the mower linkages are pointing straight toward your tractor. When your tractor's front wheels go into a dip, your three point arms, on the rear of the tractor, will naturally move in the opposite direction. Without the variable linkage on your mower, your mower's front wheels would lift off of the ground.

I believe you may be missing a small portion of the mower's linkage assembly.

Here's a picture of your mower......or one like it. Notice that the mower has a floating linkage system on the front. Make special note of the U brackets that attach to the swinging metal bars protruding from the front of the mower.

I hope this helps.

Joel

Joel, nice description.

Question though: Are the bottom floating links 100% necessary? I can lift the arms on my CUT no problem so IMHO the floating links are redundant. Your thoughts?

My buddy ahs a 6o" King Kutter finish mower with the lower links still attached, but not being used (he bought it that way) and has no problems using it on his hilly terrain. In fact, like he and I discussed when I pointed it to him, it seems under the right conditions the lower links could get rammed up or down under the mower.

I had a floating top link attachment point on my KK rotary cutter. The bottom does not float, other than the nautral float of the lower arms. I removed the top link point and installed two 2" ratchet straps from that point to the rear of the cutter body. This gives a lot of flexability to drop the rear into a ditch or pick it up to mow high berms, or drop it on a bush or shrub to mulch it (having a hydraulic top link greatly assists in the adjustment) ....

Earthwrks,

Thank you for the kind comments. I hope I explained this well enough for her. If not, I'll be more than happy to try again.

Is the floating three point system necessary?

Absolutely not. With a little bit of foresight, any tractor operator could raise or lower his three point arms in anticipation of the tractor going into a dip, or over a slight rise. However, for the person who mows several acres each day.... every day.....the floating three point system is a handy feature.

There's a guy who sells gadgets on television.......I forget his name. One of his favorite sales pitches goes like this......"Just set it, and forget it". Well, that television salesman could just as well be selling Tebben mowers with the floating three point system. Once you set your three point arms to the proper height, there's never any need to adjust them again while mowing, and the mower will never skip, nor leave any uneven grass behind.

The floating three point system isn't meant to be used for mowing ditches or embankments. It is designed for use on finishing mowers, where a professional appearance is desired. The Tebben mower will not handle any rough terrain, as the leveling wheels are spaced too far apart -- front to rear -- to make it useful on knobs, or deep dips. It is meant to be used on relatively flat ground with rolling hills, and shallow, wide gulleys........as may be found on most any golf course.

In reality, the Tebben mower, utilizing the floating three point system, makes the Three-Point mower act more like a belly mower, rather than a brush hog. It's a nice feature, but not at all necessary. It will save a lot of elbow grease, and it's very convenient for those who earn a living with their mowers.

Joel ....
