POST DRIVER ATTACHMENT

[TX Hazer]

I just purchased a Shaver HD-8 post driver. It did not have a hydraulic "return" hose on it. I am hooking it up to a MF271XE tractor and would like to know where to hook the return line to the tractor. It is a low pressure return line and just dumps the hydraulic fluid back into the resivor, but where?

Welcome to TBN TX

You can make up a adapter that fits in the fill port of your tranny...

You should be able to plumb into the return from the aux. remotes. I think there's a "T" fitting there. It's a funny thread, but, you should be able to get it.

Thanks. That was my conclusion, but on this tractor the fill opening is right on top next to the gear shift and is a little unhandy. I thought there might be some other place that I just hadn't found.

Thanks again

Thanks MFRED, I will look for the "T" fitting or if there isn't one I may create one.
Thanks

Take a look at the thread that I started regarding the same problem. I had a downforce kit for a post hole digger that is plumbed the same way. The adapter that I located allows you to hook up your return line at the filler opening. I think that it was specific to Kubota but you might be able to track down one for your model. The folks at Inland Kubota are great to work with.

I added a 45 degree adapter to clear my obstructions, and a quick disconnect. Simple to use.

Stagelines,
Thank you for the info. I appreciate your previous thread and especially the picture of the adapter you found. It appears to be exactly what I need. I will contact my dealer and see if he can locate that part or a similar one to fit my tractor.
Thanks again,

Is the line you are referring to a case drain? a third line?

 

[TX Hazer]

Actually the line is a low pressure line that dumps the hydraulic fluid (low pressure) back into the hydraulic/transmission fluid reservoir. It is coming from the post driver as it drives the post. The pressure line is then used to raise the driver. In other words the only downward pressure results from the springs driving the post driver down.

There are only two lines, the "pressure" line and the "dump" line.

I think this answers your question, but if not, let me know.

Your response is appreciated.

OK I understand the schematic, I agree with the other posts ....dump it in the reservoir, the details are up to you.

Hello,
I just went through all this on my tractor. Definitely go with the zero pressure connection to your reservoir, not with a low pressure line return. Low pressure quickly becomes high pressure when you are dumping that quantity of fluid in a split second. Your ram won't deliver the maximum force if it's fighting any pressure at all. Also, keep an eye on your hose fittings, and avoid constricting the flow smaller than 1/2". In other words, choose a return hose that will have fittings with a minimum of 1/2" orifice.

Thanks Walter63,
I took the reservoir filler cap (plug) to a machine shop and had them drill a hole on the top and tap it. I then had a new hose made that connects the Shaver driver to the plug. The hose is 3/4" and there is little pressure when it "dumps". When not in use I can remove the hose and connection in the filler plug and simply replace it with a (pipe) plug.
The hose and fittings were the most expensive part of the project.
Thanks again for your reply.
