Made my Kubota pee

Well it took less than an hour of run time and I've already broke something on my GL-21 /forums/images/graemlins/blush.gif

I was playing with the FEL last night, scrapping the drive in some rough spots and decided to do some "off roading" /forums/images/graemlins/grin.gif The loader installation was less than perfect and one of the hoses hung down below the bottom of the tractor a little bit and wasn't fastened securley to anything to prevent it from being grabbed by those massive lugs on the front tire. Sure enough, I got in some heavy brush and I think a briar or something grabbed the hose and pulled it into the tire. The tire in turn grabbed it and de-coupled the quick connect. I think the sudden closing of the coupler caused hydraulic hammer and blew the guts out of the female side of the coupler.

I got it up onto level ground within a few seconds and killed the engine. Spent the rest of the night hunting down new couplers. Finally got them from a friend who works at a local factory and they use them in their hydraulic circuits.

So now I'm going to design a port block and hard pipe as much as I can then shorten the hoses and make brackets to hold them all in place.

I'm going to have to pick up a new filter tonight and some fluid. I don't know how much this thing takes so it'll be a shot in the dark. Does anyone know if the sight glass on the back of the 3 point hitch is a good indicator of if the system is at an optimal fill level? Or is just there to monitor and make sure it doesn't get dangerously low?

I'm such a newbie at this stuff it's pretty embarassing. /forums/images/graemlins/tongue.gif

I haven't "removed" any hydraulic lines yet but currently we are clearing our property and I managed to put a 1" sapling through the front grill! /forums/images/graemlins/blush.gif

I don't know for sure on the gl-21, but the center of the site glass should be the best place to be.

jb,
Thanks for the advice. Right now I am all the way up in the sight glass and that is after is leaked about a gallon on the ground.

I emailed a company in Japan that has two GL-21's in stock and asked them to locate me some manuals. They said they would try so with a little luck I will have some in a month or two. Then I'll probably have to have them translated.

When checking the fluid level on tractors equiped with a loader the hyd. cylinders need to be retracted all the way so you want get a false reading.

BOTAMAN,
thanks for the advice also. Is that to make sure you don't put too much in the system?

For example, if all my cylinders are extended and I fill the system then I retract all of them that would overflow the resovoir, correct?

What about the opposite? What if I don't fill it enough?

For example, I fill the resovoir with the cylinders fully retracted then I extend them all I would need a minimum of .5 gallons for the volume of the cylinders(4 cylinders onloader @ 1.75" diameter x ~12" stroke = ~.5 gallons). I guess that's not as big a concern as putting .5 gallon too much in, is it?

Thanks again.
