    Default Hydraulics----AAARGH!!!!!!

    Would someone please explain a few simple things about hydraulics to me. Let me explain my project. First off, I have a Yanmar 1401 tractor. I am adding an adaptation of a thing called a Johnny bucket. It can be seen at: www. johnnybucket.com . I need to plumb in a cylinder on the front to lift and push down on the implement. So a double acting cylinder. The hydraulics parameters on my tractor are: 1565 working psi, and 2-4 gpm depending on the rpms of the tractor. So, what size bore is going to be the best, and do I use a tie rod cylinder or what? I know nothing about hydraulics other than that they are confusing. I would like to get this thing done. May be just building this johnny bucket myself other than I have no ideas on a trip latch for it.

    I went to the <A target="_blank" HREF=http://johnnybucket.com/>johnny bucket site</A>. They don't show using a cylinder on any of their products that I could see.

    What I would do is figure out the angle of the dangle. That is how much a cylinder has to move to acomplish the work you want done. Remember the longer the the throw the less energy needed if you're using leverage and a pivot point. Of course the downside of that is the longer it's going to take doing the work. Something you need to keep in mind due to your flow and pressure parameters.

    Once you figure out how much throw (distance) that a cylinder will need to operate go down to TSC or Northern and find a tie rod cylinder that has that much travel. Tie rod cylinders are the simplest to rig er uh field engineer with mostly because the pins and bushings are right there at TSC or Northern next to the cylinders.

    In your case I'd go with the minimum bore and stroke available. More will just slow down the process of operation.

    Keep us posted with pics if you can on your progress.

    Actully if you look at the users gallery on the web site for Johnny Bucket, there is a guy there that went nuts and customized his on a Cub Cadet, I believe. I think that the Johnny Bucket will prove itself pretty useful for its use, verses putting a loader on my 2wd tractor. I am going to use 2 or 4 weights from the following web site designed by this gentleman at www.p.f.engineering.50megs.com Those weights could be easily adapted to a mounting kit on the 3-pt that I have. Each weight weighs 80 lbs. As, I already have 2 "wire weights" that they use on power lines, (have a 1" hole in the middle, and are about 10" in diameter and are about 4" thick and each weighs about 85 lbs.

    Thanks for answering my question about the hydraulics. Now for deciding which valve to use. I know my system on the tractor is an open center, and has 2-4 gpm as per rpms that the tractor is turning, and has a working pressure of 1565 psi. I will look for a 10" stroke 2" bore tie rod cylinder.

    Thanks Harv

    It looks like all those buckets are all pretty much brand/model specific for lawn and garden tractors other than the 3pt hitch model. Unless you are up for a lot of fabrication, you may be better of with that one or a standard 24" pond/dirt scoop. You can sure get a lot of work done with one of those.

    I've moved more dirt than I care to think about using my 30" scoop.

    Look at the PARTS/REPAIRS and go down to "Blown hydraulic line" --there a couple of web sites listed that will explain every thing you need to know about hydraulics-- the complete US Army manual is listed there. Good Luck. Don
