The link posted above covers things nicely. You may find that raising the rear tires a little USING THE HOE is essential. I'm not sure that using the stabilizers will release the pins completely. If you only use the stabilizers with the backhoe bucket raised, there's still all that weight trying to pull rearward on the attachment pins.

When I picked up my L39, we wasted about two hours trying to get the backhoe back on it. Later, after I had read the instructions, I could do the same task in just a few minutes. The secret was to extend the hoe out a bit and use it to lift the rear wheels. Once I did that, the pins would slip in/out with the pressure of one hand.

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

No you don't raise the wheels, ya just take the weight of the hoe off the pins, one hand on pin and the other on the controls which would be the dipper ( I belive ) and just push the bucket into the ground ( the back side of bucket) till ya can wiggle the pin and after ya pull both pins pull back on the dipper handle and she will roll out of the cradle.

After ya do it a few times it gets real easy.

Dons explination is a real good one.

Took my BH90 off the tractor for the 1st time today, took about 30 minutes.
Not using the stabilizers, just the boom. Right pin came out 1st with some resistance, then I couldn't get the left pin to budge. Playing with the boom downward pressure very slowly up & down fine adjustments I finally found the sweet spot and the Left pin came out easily. I probably won't be putting the BH back on for a couple months, but hopefully I get the knack of this
eventually

When you buy your new one, make sure the dealer tech pulls the pins and dismounts the back hoe, before delivery.

In my case, one pin was jammed. An hour on site trying to get it out. We discovered orange Kubota paint in the pin's sleeve. Dremel w/wire brush and lots of solvent to clean it all up. If they're right, when tension relieved they should slide in and out easily.

My dealer showed me at his shop, and removed and installed the BH90 there, but there's nothing like doing this yourself at home without the dealer present who could probably remove the BH in his sleep since he's done it so many times.
Yes there was some crap & paint in the pin sleeves, so I cleaned and sprayed the pins & the sleeves down with Fluid film, should help the next time I install the BH.

Try this link for a video on removing/reinstalling a hoe on a BX24 -- very similar to the procedure on the bigger tractors.

Drat! I hate it when I forget to post the URL. Here you go.

I had a BH90 w/a L3830 and can attest to the challenges of mounting/dismounting the BH. (It is an EXCELLENT BH by the way...smooth, precise, easy to control.) Several previous posts are right on...namely keep BH on level surface and download TXDON's post...it helps when you aren't doing it everyday. (You don't lift the tires off the ground because that will not releive the pressure/tension on the pins.) I once dismounted mine in an out of the way area on the ground and the following day tried to remount it, but it settled unlevel. It took about 90 minutes to get the holes lined up perfectly to place the pins back in...the tolerance is zero, so perfect alignment is crucial. I did everything possible...using the bucket, dipperstick, stabilizers, etc. to get the darn thing lined up. Anyway, dismount on a slab if possible or use 2xs to keep it level so you can remount without hassle.

I now own a JD 448 BH and rally like the way it mounts as it is lifted into place and the pins are slid in from the seat without a fuss...level ground or not...no matter. On the flip side, the 448 is FAST and takes a while to get used to it. It also has a little more slop in the side-to-side play, so working in tight spots near the house requires extra care. I'm not sure if the extra speed of the 448 is worth it.

Anyway, with time and practice you will find it gets easier. ENJOY!
