Implement max width.

Jeff_fergy20 · May 14, 2012

Hi all, I just purchased a 30 inch reversible dirt scoop. The two lower linkage pins are set about 31+ inches apart and they face inwards.
The problem I’m having is that when I lift the scoop up, the width of the bucket puts strain on the lower linkage arms to the point that they actually bend inwards in the middle- basically at the lift rod connection. This seems to make sense as when you lift the arms without an implement the stroke of the arms is quite wide when lowered and narrows up at top. So, If I’m exceeding the limits of implement width, what are my options to correct this? If I shorten the check chains I assume I will stop the lift sooner thus reducing the inward strain at the top of the stroke, however this would also reduce the height I’d be able to attain to dump materials into another vessel (ie trailer). Is there such a thing as extra long implement pins that would enable me to move the arms in closer together? Are there other options I’m not considering other than modifying my bucket?
Thanks in advance again for any and all advice.

I would think if you added a link that should correct your problem. I think the main function of the check chains are to limit side to side movement at the top and bottom of lift arm travel.

I think the regular inside width for implements for the ferguson & n fords was 26 to 27 inches.

It sounds like your check chain brackets are fitted upside down or
at least the chains are anchored too low on the brackets thus
restraining the lift arms from reaching the top of their stroke. Look
at the brackets and see if you cannot fit the chain muzzels in a
higher hole or even swap the brackets to the other side and the
other way up.

The top picture is the correct position for the chains on a TE/TO 20 the bottom picture is correct for a 35.If your anchors are in either of these positions then you need more links in the chains.
You will see from the pics that the 35 type can be used either side as they have a top and bottom hole the Fergie type are actually 'handed' and may need swapping as I said before.

You can reverse those pins to go to the outside.
The restricted chains are to protect your tires from getting
worn down by your lift arms.

Thanks guys you are right. the check chains are indeed to short because they are installed on the bottom hole on the plate around the pto. I have the stablizer brackets, so for the scoop i will just remove the chains as the brackets prevent swaying.

i didn't specify but i have te20. this dirt scoop i picked up seems to be a fantastic option to a fel. thanks again for the advice!

That scoop is not Category 1 which is what you need for that tractor. The lower links should be 26.9" apart when the implement is fully raised, this is measured inside one lower link to the other. The Top Link Pin should be 18" from the center of one of the lower link pins to the center of the Top Link Pin. The Top Link Height is more important on Depth controlled implements as it changes the leverage applied to the Draft Control and would make it more sensitive to fluctuations, it should never be any higher than 3" above the standard setting, but it must always be 18" for Draft work.
Unless the implement rises fully it will keep blowing the Safety valve because it is not rising far enough and allowing the system to shut off automatically. It is not the tractor that is wrong it is the Scoop that needs altering.Without checking it I think tat the Scoop is a category 2 implement for a bigger horsepower tractor...John(UK)

Even though you have found the check chains attached incorrectly, the measurement for the linkage attachment are not right for a Category 1 tractor. The check chains should be 7 links with a "D" link at each end, this is the correct length. The Chains should be just almost tight when the implement is fully raised, this prevents the implement swinging, if it can move there is more chance of it swinging into one of the wheels....John(UK)

Is there a standard size chain for this use? John, you mention 7 links of chain but that would be a different length depending on the size of the links.

John(UK) · May 15, 2012

That is perfectly true, the problem with saying something on here it always leads to another question..lol...The Chain Links are 5/16". The total length of each chain from one pin hole to the other on the "D" links should be 10.42 inches (a little less than 10-1/2"which is 10.50"inches)Just make sure, no matter what model of tractor that you have, that the inner end is attached to the anchor brackets above the level of the PTO shaft Grey tractors usually only have one hole in the brackets, 35's usually have two. I say "usually" because some aftermarket parts are not always like the originals.The length of these check chains is very important if they are too long it could allow the implement to swing into the wheel or just allow the implement to swing a little and the the tractor would be unstable when the hydraulics are raised..John(UK)[email protected]

Hi John;

I think the check chains have been the issue all along. they have been fitted so tight that the implement has never had the chance to lift high enough to shut off the pump via the top linkage. with every implement i have when i lift up the check chain stop it at the top, not the saftey.
