Plumbing for a grapple

[PatMcD]

Thinking about getting a grapple. Any reason not to use my up-to-now unused rear remotes?
Hose and fittings from NAPA and some way to run the lines down the loader?

I've got a spare 8' snowplow blade that I want to hook up also, so need hydro out the end for 2 things.


Never used those rear remotes, so want to make sure they will work the way I want them. They are two-way, spring loaded back to neutral. I want to go grab something with maybe a lot of pressure or a little by using that remote lever in one direction; when it springs back to neutral, will the pressure stay on the grapple until I push the lever the other way?

Go for it, it's done all the time. FYI you only need to use 1/4" hose, it's cheaper and easier to route all the way to the front.

Unless the valve leaks off, the pressure will stay on the grapple just like you FEL works.

I would go to Surplus Center for hoses;I found NAPA to be outrageously expensive;like ten times more expensive.

Here is how I did mine;

I asked the grapple maker today and he said "1/2" hose, well maybe you could downsize to 3/8"". It's coming Tuesday, so I'll have a few days to work on my parts list (after plowing out from however many feet we get this weekend).

What size are the fittings on the rear of my tractor? Can you tell I don't know much about hydraulics?
If I order from surplus center or any other online place, will they send me hose of the correct length with threaded ends?

I figure I'll run a rope around how I want it to get the length, make up some sort of hard mount for the fittings at the end of the loader arms.


EDIT: I just went to surplus's website and everything looks pretty self-explanatory

The rear remotes take 1/2" AG fittings, and I think you would be fine with 3/8" hose, works fine for me.

 

[nybirdman]

3/8"hose will be fine,you will need to match your rear connections and purchase two sets of matching for the front.Mine is set-up with a male and a female on the tractor and a male and female on my plow and grapple.
There are check valves in both the male/female.

 

[kennyd]

1/2" hose is just ridiculous, 3/8" is fine if you want to spend some more money but again its just not needed. The small 2x8 cylinders used on most grapples, and 1-1/2x10 cylinders on snowplows hardly use any fluid at all to operate.

Nice tidy job Underdog.

 

[Bluesteel]

Do you have to fill the hoses with fluid? How do you bleed the system?

No, and it self bleeds in just a few operations of the lever back and forth.

I used 1/2 inch hoses, but I would not recommend that. Too hard to run and bend. I put Quick Disconnects in the middle too so I could take the loader off easily. I got my hoses from surplus center. I used a garden hose instead of a rope, but same idea. Mine work great.

Thanks k0ua. I can see where the smaller lines would be easier to work with. Not having the 3rd function hyd. and the rocker switch on the joy stick is it easy to get onto using the rear remote. Moving hand off stick to open and close?

Well I can show you my Kioti pictures, but I don't know where the control is on your LS, It is very convenient on my Kioti, but I extended the lever so I could reach it better. here is the thread.

My R4041 levers are to the right and below the seat. I don't have a problem using them with my grapple once you get used to it, I am not in that much of a hurry that I need to operate things that fast any way.
I don't really see the need for the diverter valve for my uses. Don't worry about the switch on the joystick now, you can always add that later if you think you need it.
I think you could extend the levers pretty easily like k0ua did, (nice job k0ua!)

Underdog and k0ua, nice neat jobs! That's what I'm aiming for.

Thanks.
I changed the mounting of the couplers at the front of the loader, I'll try and post a pic later.

3000 psi hose good enough?

yep...

What size cyl is on that grabber that it needs 1/2 hose? I'm doing one now and I'm going with 1/4". After you start running the hose around the tractor I bet you wish you had used 1/4". Why do you need all that speed?
