Backblade problem

[scorpion12]

I've got a backblade on the back of my Yanmar 1500d. It has a tendency to swing to one side or the other when my tractor is on the side of a small incline... not a big problem until the stabilizer bar catches on the tread lug of the tire and stops it... there's a jarring slam as the tread moves past the stabilizer bar and the back blade drops or... like what happened the other day, the tread lug caught and stayed caught... the left rear wheel stopped moving and the tractor stalled.

Is there any way to keep it centered so it doesn't swing towards one side or the other? My land isn't level and I don't want this to keep happening and break something.

Not sure what your 3 point arms look like but most tractors have either chains or turnbuckles coming from lower hookup points. Those points are used to tighten up the slack so the 3 point attachment can't swing too far left or right. On my ole Oliver Super 55, it had a straight on one side to stop swing. You should be using one of the above for safety reasons, you could get injured if tire runs over 3 point arm.

What devildog1 said. Can you post a picture of the 3ph arms by chance?

 

[scorpion12]

Sure. I'll see what I can do... it's dark now though. It's got turnbuckles. I definitely want to use it safely. I've only had a couple of instances where I was "skurred" the tractor was going to do something I didn't want to do...

Once you find and understand these turnbuckles you will be good to go.

Took me some time to discover the same problem you have.

Also, the turnbuckles are a blessing when attaching an implement. Loosen them to start to get a better "fit" to your 3pt. pins, then snug them up for operation.

Keep and eye on that. You can ruin a set of rear tires in a hurry if an implement swings outs and starts chunking the tire.

I wouldn't know that from personal experience.....

 

[scorpion12]

Alright, I've had a chance to take a few photos and I think they're attached...

Photo 1 shows the left link is solid... the right one is the turnbuckle... sorry I couldn't turn the rest the right way...

The turnbuckles that are mentioned are not talking about the vertical turnbuckle you see on the right lift arm. They are the smaller horizontal ones on either side of the drawbar (below the PTO). Tighten up those turnbuckles to keep the blade from swinging side-to-side.

As rus geek said, use the turnbuckles which a parallel to to ground to adjust out most of the sway in the rear blade. Raise it off the ground and start tightening until it has only a little sway. A little oil or WD40 may make it easier to adjust. Use the more verticle turnbuckle to level or create and angle with the blade to the ground such as when you would want to create a higher center (crown) in the driveway to allow for water to drain off.

Awesome! I'll tighten them up as soon as I use my tractor next. I've got a few trees that I felled today to try to drag off. Taking the slack out should help alleviate the issues I'm having.


Do I raise the blade all the way and tighten them up, or just barely off the ground, or somewhere in between?

Thanks y'all

Raising it just off the ground is fine. It wouldn't much matter, but on mine if you raise it all the way, the arms are force against a bracket which would tend to limit its movement. Remember, anytime you have an implement off the ground, it can go down and quick, so keep all body parts such as fingers or toes that you want to keep out from under it.

Add this....When tightening the turnbuckles leave a bit of "play" or "swing" in the attachment. Just a bit.

 

[scorpion12]

Alright... I went out to tighten the turnbuckles and was successful on one... it kind of removed a bit of the slack... but the other one... the head of the eyebolt snapped right off.

Looking at the threaded portion, it was rusted completely through. I guess I'll get two new turnbuckles from Tractor Supply this coming weekend and tighten them up a bit.

Son of a gun.!!

You'll get there.

At least turnbuckles are cheaper than new rear tires..

...two new turnbuckles...

Maybe find out if they have a set of telescoping stabilizers while you're there? They are typically easier to adjust than the turnbuckles, and probably less likely to rust-weld themselves together.

Below is a picture of telescopic stabilizers like what rus_geek is referring to. I recently switched my turnbuckles out for these. This is the system used on the more upscale Kubota than mine, so was a direct replacement. They adjust easier which makes for easier replacement of implements and I like them because they hold the lower lift arms at a set spacing even with no implement on. Before mine would swing in as soon as the implement was removed. In the picture you can also see I use the Pat's quick system which makes the switching of implements a very easy task.

 

[scorpion12]

Those look pretty cool and a lot better than what I currently have.
Where can I get that? How much is it?

 

[KU Gator]

I ordered them through tractorsmart, but as I mentioned they are Kubota specific and I'm not sure if they would fit yours. They were $200 delivered, so more than I would want to take a chance on. You might try checking on the Yanmar forum section to see if anybody has ideas. Or do a web search. The reason I posted the picture of mine was so you would know what Rus_geek was talking about by telescopic stabilizers. If you can find them that will fit yours and you have to replace what you have anyway, even if they are more, they are an improvement in my opinion.
