Backhoe JD 48 Backhoe

[Chris in IN]

I have a JD 48 backhoe that when I am using it on uneven ground I level the tractor with the stabilizers. Within in a few minutes the wheels have settled to the ground. When doing loader work with the backhoe mounted I have to watch to make sure the boom does not settle enough for the bucket to drag the ground. When I put backhoe in the parking position & remove it from the tractor the stabilizers will settle about half way to the ground & the buck will curl up. Has any one else had this happen? Chris

Actually when you are doing anything and don't plan on using the backhoe, the transport pin should be in it, you will save a lot of seal life. It's really tough for that hoe to hold itself up when you are bouncing around. The hoe is not meant as a perpetual defier of gravity/w3tcompact/icons/smile.gif

If you are going back and forth between loader and hoe, or plan on using the hoe to offset center of gravity left or right you of course may not be able to put both pins in.

The business with the legs is aggravating I know, I think it depends on how old the hoe is, my Kubota doesn't do it (yet/w3tcompact/icons/wink.gif) my Ford does it but it's older. It's not at an objectionable rate, I just have to goose the outriggers now and then. Some of that on my property I have to do anyway as the ground settles underneath me.

According to the JD sales brochure I have, the model 48 backhoe will fit on the 4300-4700 series tractor. Does anyone know if the model 48 will fit on a 1996 JD1070?? I plan on calling my dealer to quiz him but thought I'd put it up for a vote here first. Ok John Miller lets have it............/w3tcompact/icons/wink.gif

I'm pretty sure it's the subframe that the 47 & 48 bh attatches to that they're talking about. You'd probably have ot find out if the make a subframe for that model for the bh to hook up to.

Thanks Jerry. I'm going to give my dealer a call tomorrow and quiz him. I'll post the results of my call.

The is no subframe for the JD48 backhoe on my JD4700. I have plates/brackets bolted to the rear tractor housing which provides for quick attachment and disconnect.
I had a JD7 backhoe on my old JD755 and it had a subframe.

My 48 hoe leaks down the same as yours. I do was Del suggests. I keep the transport pins in place when I am not using the hoe. I also made up a short piece of light chain that I connect between the cotter pins on the stabilizer pads. The chain is just long enough to reach with the stabilizers fully raised. Works great to keep the stabilizers up. When I take the hoe off I park it with the bucket fully curled in and set it down on a 1 foot long piece of 8x8 wooden block. This keeps the bucket cylinder from leaking down and upsetting the position of the hoe. I think the leakdown rate is normal for the hoe. That 48 hoe is one awesome digging machine. Hope this helps

My 47 leaks down also along with my fel. I almost always put the pins in when I'm not using the bh. Other wise I have to constantly reach back to lift the boom. I likethe sound of your chain setup for the stabilizers. I've thought of doing the same thing. They do bleed down and if I don't watch them, after a while they could be down far enough to catch something as they will be sticking out farther than the back tires. As far as unhooking the bh, I just put it on the gound with some rubber belting under it. After it's on the ground with the bucket curled I unhook the hyd., release the pressure by moving the sticks around and lower or raise the stabilizers to relieve that pressure. I take mine off using the stabilizers not the rock shaft. Haven't had a problem doing it that way.

Chris, I don't think your tractore/backhoe should be dropping down .Especially, "in a few minutes". I have a 4300 and 48 backhoe. I can do front end work, without my backhoe pins, in place for an extended time and the boom doesn't drop. Also, when I level my backhoe for digging. The stabilizers will keep my tires in the air for a very long time (I've only stayed in one spot for 30 minutes or so, but never saw any drop) . If you are dropping down, my guess is a hydraulic problem.

I've also got the 48 backhoe and mine doesn't leak down like that.

This is a follow up to my post on 12-9-01. The backhoe mounts on the 70 series are completely different than the 4000 series. Tony's post talks about how the 4000 series backhoes mount on brackets as opposed to the 70 series which was a subframe. I was hoping the two were compatible but not so. Since I'm going to pass on the backhoe, anyone near the Lake George, NY area looking for a JD48, theres one for sale.

Here is one way to keep the stabilizer rams from collasping when hoe is stored. Take a piece of schd. 40 pvc pipe with and id close to ram shaft diameter and rip in two on a table saw.
Cut to extended shaft lengt desired and clamp both half's to
shaft with two rad hose clamps. You may want to set length BEFORE ripping pipe in half.

Regarding the leakdown, depending on the serial # of your tractor, you may have a problem with the rockshaft valve. Our dealership has replaced approximately 6 of these valves in the past year, so if your serial number is under -300000, quite possibly you have a rockshaft valve problem. If you out of warranty, ask the dealer you purchased the tractor from to inquire about a John Deere Special Allowance, because this is a very expensive repair.
