Backhoe Backhoe Pictorial Tutorial - Removing BH90

[txdon]

When I first started looking for a tractor last year I found out from TBN that the manufactures make backhoes for their tractors. However, most dealers did not have one in stock and only one dealer offered me a "try before you buy" hands on demonstration. One of the questions I had was how easy is it to get on and off? So when I started taking the backhoe off today I grabbed my camera and owners manual and . . . .

The engine should be at speed idle and on a flat level hard surface preferably concrete or on boards if the ground is soft.

1. Set the swing lock pin to prevent the pivoting of the boom before removing the backhoe.

2. Stand beside the rear tire, fully close the dipperstick, curl the bucket and lower the boom until the back of bucket contacts the ground.
3. Keep the stabilizer pads at about 15 inches high.

4. Raise the rear wheels slightly with the boom and remove the mounting pins.
(Note: you actually do not raise the wheels as the manual states, just take the pressure weight of the backhoe off the tractor so you can slide out the pins.)

5. Slowly raise the boom to disengage the backhoe from the tractor.
6. Raise the backhoe by operating the stabilizers to the lowering direction until the mount bars hit the guide stopper on the support hooks.

7. Move the tractor forward from the backhoe about 8 inches. Be careful not to damage or break the hoses when moving the tractor.

8. Lower the main frame and swing frame on to the ground by operating the boom and stabilizer control levers.
9. Shut off engine and set the parking brake.

10. Slowly release all hydraulic pressure by moving the backhoe hydraulic control levers in all directions.

11. Disconnect hydraulic hoses on the following manner: (1.) Disconnect the inlet and outlet from the tractor. (2.) Connect tractor's outlet hose to the coupler of return hose.

12. Restart the engine. Then drive the tractor/loader slowly away from the backhoe.
13. Shut off the engine and remove the key from the tractor. Set the parking brake.

Apply a coat of grease to all exposed cylinder rods to prevent rusting. When storing backhoe, install the dust caps onto the backhoe's hydraulic nipples to prevent contamination.

The end. /forums/images/graemlins/wink.gif

Thats about how the L35's backhoe comes off except it has big hooks on both sides that the backhoe rests on. Very easy to take on/off.

Excellent post and pix Don. I guess the method stated in the manual works well and would have saved me a lot of frustration if I had had the manual before attempting to remove mine.

Once you get the procedure down pat, it really is a snap to remove and reattach. The key, as I see it, is relieving the pressure in the lines!! When I get that solved, I'll be all set!

Thanks again,

Nice series Don.

It certainly will help others in the future. Good job!

Interesting to see how the BH90 differs from the BL4690A.

I don't have a backhoe, but I am sure many others will really appreciate this post.

You have done an outstanding job documenting and commenting on the procedure and pictures.

Well done. Another example of TBN at it's finest!

That's awesome don, could I ask for one more picture? The back of the tractor showing the bh frame and the 3pt lift arms attached.
Thanks

Leroy, The BH frame does not interfere with the 3 point hitch or T&T. See attached photo.

From the other side.

Interesting pictorial. Amazingly similar to removing the BX 'hoe with the exception that the BX "pins" are captive and spring loaded.

Great post. Very informative and useful to see these type of photo essays even if you don't have the machine in question.
