I seen on some front end loders, an extra peice at the end of the tilt cylinder where it is pinned to tht bucket. Is this to increase tilt 'geometry' or ..... and also what is it called ?? Thanks Jim.

67PLY,
I think you are talking about the indicator rod. As the rod runs back up the loader arm it should pass thru a bracket called the guide. There is a sharp bend in the indicator rod and it can be adjusted so when this bend is at the guide the bucket will be level. There are some loaders - usually on row crop tractors - that will have an extra rod & brackets on the top of the loader arm - this has to do with keeping the bucket level at all times. This is the type of FEL my neighbor has on his Versatile MFWD 305.

Are you talking about the 4 bar linkage?
Then yes it helps increase the range of travel of the bucket. Depending on how the link is designed it can also give additional force during some range of stroke

I really do not know what the arrangement on his FEL is called. I know when he puts on the bale spear it will lift the round bales all the way to the top of the stack without needing constant adjustment to keep them level. You talk about fun seat time. This week and all of next week I'm getting to help him in his custom cutting and harvesting. I'm getting to drive the big Versatile.

Is this what you mean?

View attachment 3 This is the system I'm familiar with and the neighbors tractor has.

Looks like self-leveling as well as the extra linkage for enhanced bucket control.

Jim,
I haven't forgotten the original question. Its just that I'm not very handy manipulating the pics I've got in my files. This pic shows the indicator rod running up the right arm of the loader. I think that's what you are asking about.

If your talking about the parts in xring's picture, which I'm fairly sure you are, then yes they increase the buckets range of motion.

"Self leveling" is on some loaders. I don't like it because it's jerky, moving some distance then automatically adjusting the bucket. At least on my B21, it's not a continuous adjustment.

The top links, parallel to the boom arms (above front tires) are part of the linkage for mechanical self leveling.

You might mean hydraulic self leveling that uses a valve in the dump/curl cylinders and only works in one direction. Mechanical self level is smooth, no jerky at all.

Your description is the 4 bar link like the picture xring posted. Some backhoe buckets also use this set up.
It dont really increase the range of travel, or the force at all. But what it does is allow a longer cylinder to be used, to gain greater travel, before the cylinder rod contacts the loader arm.
So if your cylinder is 20" long, and all other geometry being equal, a 4 bar wont give any greater travel than pinned straight to the bucket.

Not sure about anyone else's hydraulic self leveling loader, but mine is smooth as can be and can work in both directions if that is desired.

I have a mechanical SLL on my ford 5500. It is also smooth as silk.
Probably a good bit smoother than me feathering the curl while raising on my NON-SLL kubota:laughing:

Same for me.

You seem to contradict yourself. A longer cylinder would seem to imply that it allows for more travel based on your statement. If a longer stroke is not possible without it you can't get the extra range.
simply put 4 bar linkages translate motion. Bolt cutters use a 4 bar linkage to multiply cutting force. Large angular travel input and low force translated into low displacement high force output.
I didn't say all linkages were designed to increase force.

Don't believe me here's what kubota has to say about it
"Thanks to an upgraded 4-bar bucket linkage, the rollback and dumping angle has been increased for quicker scooping and dumping."
Still not convinced take some mechanical engineering courses

I didnt contradict myself, but maybe I wasnt clear.
Lets use my kubota for example. Its a L3800 with a curl cylinder directly pinned to the bucket. And IIRC, it uses a cylinder with a ~20" stroke.
IF, I added a cylinder of 24" stroke, I would gain curl angle/ range of travel, BUT, would get to the point where the cylinder rod hits the loader arm, so its not possible.
IF, I added a 4-bar linkage like used on loaders, I would gain nothing in range of travel.
BUT, using the 4-bar keeps the cylinder rod away from the loader arm and allows for the use of a longer cylinder.
Bolt cutters are a totally different thing...
And lets keep it civil. No need for the digs and insults.:thumbdown:

Sounds like the self-leveling is done hydraulically on your B21. Is that correct? The mechanical self-leveling loaders should be very smooth.
Edit: Sorry, I didn't see page 2 where self-leveling was discussed further. With that said, I remember experimenting back in the '70's with development of a self leveling loader using a flow divider valve to level the bucket as the loader was being raised. The project was less than successful.
