Front Loader with 2 way cylinders

Smith1000 · Mar 9, 2015

I put a front loader on a Super M and the loader has 2 way cylinders. I really don't need or want the down pressure. I took off the line for the down pressure, but the bucket goes down very, very slowly. Is there any way to alter the cylinders to go down a little quicker? My old loader was for a narrow front end and it had 1 way cylinders. The bucket dropped fairly quickly. I changed loaders because this one will fit over a wide front end. I have a wide front for it that I am wanting to install soon. Thanks.

Assuming you vented the rod end?

Don't want 2 way cylinders?? Leave them that way and you will find they are the bees knees. You can change a tire and not use a jack. If you really want to dig you can. If you start to spin out you can lift the front of the tractor up to shift weight to the rear tires etc etc. I hate one way cylinders on loader and when I can I ALWAYS switch to 2 way

I didn't, I just removed the hoses. There is a narrow slit in the ends of the cylinders. Do I need to put in vent holes and do I drill them?

You can get vented plugs that just screw
into the holes the fittings came out of. What ya might consider is adding some weight to the bucket if the vents don't work. Also can make sure the dry end of the cylinder is lubricated some. It should on its own but never know sometimes.

Keep the cylinders 2-way!!!! You will never regret it. Use it and enjoy!! By the way is the bucket mechanical trip or does it have hydraulic 2-way cylinders to dump the bucket? If a mechanical dump you will want to convert to hydraulic dump as soon as possible be your loader will so much more useful! Armand

Even if you don't want the two-way action you can
still route the rod end hoses into the bottom of
the reservoir. This will provide a way for them
to "breathe" and will reduce the amount of oil the
cylinders consume from the reservoir when
extending. You for sure don't want just open
holes in the cylinder since you'll get dirt sucked
in there which will wear on the piston seal.

Smith1000 · Mar 10, 2015

I have the ends of the open hoses covered with wash rags currently to prevent dirt from going in. I may have to put it back to 2 way if I can't get it to drop quicker. It is a trip bucket, which works fine for what I do with it. I just use it to move hay around. Thought about just putting the cylinders off the old bucket on, but they are slightly too long.

2 way is always more useful but everyone
has their preference. A vented plug should
fix your problems I would think. They
shouldnt cost much at all. Make sure all
the linkages and pivot points move freely
and sometimes cylinders are just really
tight and just don't work very good set up
on 1 way. Hopefully this helps ya out
some.

Does your tractor have both single and double acting controls?
Sounds like the loader is falling down against the relief valve of
a 2-way system.

But if you hooked it up just like the old loader, it shouldn't be?

Just a thought......

Has the loader been used much, is it rusty pins or binding
somewhere, does it fall faster with a load on it, what other
symptoms? Is it a mechanical hang up or for sure a hydraulic
issue. Then is it a loader hyd or tractor hyd issue.

You should be able to make it work like the old single acting
loader.

why would you want to do that 2 way are way better
than one way setup period. use it like it is and
enjoy.

As Paul asked, is your Super M set up for 2 way or 1 way cylinders? If it's set up for 2 way, try changing which coupler you are hooked to. Not sure on a M, but some tractors, you could only use 1 side of the 2 way coupler for one way use, your control lever will work backwards. Just a thought. Chris

Dad had one on an H one time with two way cylinders. The dealer mounted it for him. They put a T in the filler pipe on the pump and ran the return lines back to that. It let the air in and out and if any oil leaked by the inner seals,it went back in to the reservoir.

Smith1000 · Mar 10, 2015

When 2 way, I had it hooked up to the remote lines--push in on the rod for down and pull back for up. Currently, I have it hooked up just like the old loader was, which is a split off the hydraulic line that goes to the 3 point. So, it seems like it would come down fast.--like the old loader. Trying to understand how the vent plugs will allow it to come down faster. Do they create a slightly larger opening that the open hoses have currently? They must, otherwise it would seem like it would come down at about the same speed. With it hooked up as 2 way, when I would try to use the 3 point, I must push the top rod forward to allow the 3 point to function. So, when I am on the 3 point, the front loader slowly goes to the ground and stays there. So, I kind of thought since the way I had it set up with the old loader worked pretty good for over 20 years....but it goes down to slow.

Smith1000 · Mar 10, 2015

I just went out and pulled off the most forward hoses completely off the cylinders and it drops about the same speed as before, so I put them back on for now. Seems like the plugs would not gain any speed for it.

Are the cylinders the same as the ones you took off? Maybe the oil is not "exiting" as fast as the old cylinders(smaller hole restricting oil?) and that is why it isn't dropping as fast.

Traditional Farmer · Mar 10, 2015

How large are your cylinders? The line letting the
oil come back out of 2 cylinders will only let so much oil thru it.Also if you are using a quick disconnect it might not be fully open.A piped in line would probably let the oil flow better than a quick disconnect anyway.

Smith1000 · Mar 10, 2015

There isn't a quick connect. Instead it is directly threaded into a plumbing T. Definitely is a difference of some sort between the old one way cylinders v the 2 way cylinders. The former one way cylinders drained back fairly fast. The hole opening is about a half inch in diameter, so that must not be large enough to allow gravity to push the fluid back out rapidly. The bucket is fairly heavy though. Would think it would move faster than that.

paul · Mar 11, 2015

Not likely, but. Was it in a tractor with a big hyd pump, and has
restrictor a in the line so where to slow down the loader?

Paul

Plowboy1 · Mar 11, 2015

If it's very cold out your way, that will make that hydraulic oil thick as molasses!

Donald Lehman · Mar 12, 2015

I am assuming you removed the down pressure hoses from the hydraulic cylinders? If you plugged to holes the hoses screwed into, you are creating air pressure resistance as the cylinder lowers. The lower the cylinder goes the more the pressure builds up and the slower the cylinder will work. Those plugs have to be vented.

Am I interpreting your post correctly?
