Backhoe Removing a BH90 backhoe

[BarKay]

After digging out about 50 stumps I decided it was time to remove the backhoe and hook up the brush hog. The instructions look easy enough but when it says "raise the rear wheels slightly with the boom and remove the mounting pins" does this mean just take some weight off the wheels, or lift the tires off the ground?
And the big question is--how do you remove the pins? Looks to me like they're stuck pretty tight. And I assume that lowering the boom should remove tension on the pins but I don't get it.
Can someone help me out here?
Many thanks

Push into the ground with the bucket untill you begin to take weight off of the rear tires. This will release tension on the pins. You will know when you have it as you will be able to jiggle them around. Remove the pins, make sure you have the stabilizers down..... lower the backhoe with the stabilizers, then pull forward a few inches. Shut down the tractor, disconnect the hydraulic lines, then couple the ends together (backhoe to backhoe, tractor to tractor), then you can restart the tractor. It takes a little practice, but you will be doing it in a couple minutes with some practice.

Thanks Ductape,

I tried it pretty much that way but the pins never seemed loose. But now that I know I'm on the right track, I'll try it again in the morning. Thanks again, and thanks to everyone for all the tips--this forum has been real helpful to a first-time tractor owner.

Assuming it is similar to my BH80X, loosen and remove the nuts first. Then as you start to take weight off of the rear tires with the hoe, you will feel the pins are completely loose and almost fall out by blowing on them. OK, i'm exaggerating a little bit....... but it will take nearly no effort to push then out. As you start to raise the hoe and put weight back nto the rear tires, you'll want your stabilizers about touching the ground. If not, the whole hoe will fall to the ground once the tension is off of it. Hard to explain in a few sentences, but its easy to get the hang of once you've done it a couple times.

Back on 5-16-2004 "TXDON" posted an excellent message on the removal of a BH90. You can find it on page 20, message # 4911.

I have an L3830 with a BH90, and it gets easier every time you remove and reinstall the backhoe. I think the manual says to remove with the bucket curled, but my best results are always with the back of the bucket flat on my shop floor. Probably the most important thing you can do is find the levelest spot available -- a concrete floor works great.

It's actually a very easy procedure.

A friend and I wrestled with the pins for a while but we got them out. For the first few months I owned the tractor it was stored outside, which may have been part of the problem. The pins had a fair amount of corrosion on them, which we took off with #400 emery cloth. Now I've built a garage for it so it should be OK. And I wiped the pins with a little grease even though I don't usually do that for non-moving parts.

Thanks for the help.

I have always used the stabilizers to raise the rear wheels rather then the bucket arm. This is after the bucket is already on the ground. Once the pins are out I lower the stabilizers just enough to pull the tractor forward, shut it down, disconnect the hydraulics and finish the process.
Be careful how low you go with the backhoe when removing it. I cut the hydraulic line on the pto shield one time by lowering the backhoe too far . Just go low enough to clear the sub frame when you pull forward.

I figure the BH90 should be very simular to my BH75. I use the stabalizers just to get the height and then use the bucket to curl it out of the mount.

I also clean and re-grease the pins/holes everytime I pull the hoe off to keep corrosion at bay.

Great idea! I'll have to try this method

Hi Wushaw,
Haven't removed my BH90 yet, but probably will give it a go this coming weekend. Your method sounds like a good alternative.

Can you just explain a couple points?
You are using the stabilizers to lift the wheels? > Then pull the pins?
> Then use the bucket to curl it out of the mounts?
I'm sure once I give it a try I'll figure it out, but right now I'm trying to visualize
