Kubota B6000

[auldyin]

Hello everyone. I'm a newbie here. I bought a B6000 in order to tackle my large/ish garden. I am aware that the P.T.O. turns anti-clock but that should not be an issue for me. I have purchased a small backhoe and therein lies my first problem. In order to get hydraulic supply to the backhoe I require to obtain a double length banjo bolt. The banjo fittings on both supply and return pipes are permanent fittings and I would prefer not to replace the full monty. In order to identify the thread diameters and pitch, I bought a parts manual. It's as much benefit as a chocolate fireguard. Parts are described as bolt, washer, nut, rod etc. No /forums/images/graemlins/confused.gifspecification/description whatsoever. Can anyone help. Perhaps a workshop/service manual has the info that I'm looking for? I'm reluctant to dismantle parts in order to identify specs.
Many thanks in advance,
Best regards,
Auldyin. /forums/images/graemlins/confused.gif

Hi,
Are you sure that changing the banjo fittings is the correct way of getting pressure from the system, though I never played with it myself I think that other people have got pressure from the cylinder cap output, which I belive is between your legs when sitting on the tractor, I attached a picute of where the diverter valve would be placed.

I owned a B6000 for several years. Great little tractor, but to be honest with you I don’t think the hydraulic pump will be up for the task of a BH. Not sure it can produce the volume you will need. Have you considered an external PTO pump?

I have a B6100 w a BH. It has a hydraulic pump run off the PTO. Independant system from the FEL.

Gary, am I right in saying that the front loader is run off the stock hyd pump, if so the poster doesnt mention he has a FEL so maybe the backhoe would have enough pressure off the pump?

Auldyin, is the BH a Kubota stock one or a aftermarket one? Do you have a loader running off the stock hyd pump?

Mith,

A few years ago I got to play on a B6000 with a FEL running off of the stock / internal pump. It was sloooow. It had small pistons and it still was slow. I may be wrong, but trying to use the curl and crowd on the BH at the same time might be asking to much from that little pump. It can supply enough pressure just a little shy in the volume department.

BTW, the guy that bought my B6000 will be building a FEL for it, he is going to use an external pump. I will try to get some pics when he does.

Hi Gary,

Many thanks for your reply.

Because of the anti clockwise rotation of the PTO it would have to be a pump that would have bi-directional function. I was intent on avoiding a B6000 because of such limitations but I got it at a good price and, hopefully, next year at this time it will have served it's purpose. Regarding the backhoe. When I collected it, I saw it run on an Iseki of similar capacity to the B6000. It would not have won any competitions but think/hope (fingers, toes and eyes crossed), it will do what I want of it.

Will keep you posted.

Best regards,

Ken.

Gary, I see your point, would love to see the pictures too!

Ken, you sound like I did when I bought mine, didnt want one but the price was right /forums/images/graemlins/grin.gif

To be honest I think getting a pump on the PTO would be your best option being what Gary said. I dont think that anticlockwise pumps are atall uncommon, it might be worth looking into. It would be very frustrating if the backhoe was too slow.

Hello Danno1,
Thanks for responding. This is the first forum I've joined and find the community spirit is tremendous.

There is no front loader on the wee beastie. Backhoe and 3point to move and reposition the BH is all that will be asked of it.

When replying to Garry, I discovered the attachment function and uploaded a pic of a double or extended banjo bolt. Hope this will provide some insight as to where I'm trying to get to.

Best regards,

Ken.

Hope it is ok to address all your individual observations in one rather than by individual responses. The Bh is quite dinky, and attaches to a compact or a skidsteer. I feel optimistic that I will find ways to optimise it's performance but, in saying that, I will have no need to push it too hard. My objective is, by this time next year, to get my property sorted out/up and sell up. Gonna buy a boat and become a sea gypsy or go live in the sun. Will be 65 then hence my nick "Auldyin". I'm heartened by your view (Mith) that anti-clock pumps are not uncommon. Was, if necessary, contemplating opening up the mission case and finding the gear train that creates the anti spin. Feel certain there is a means to make it go clockwise. Other option would be to integrate an electric pump in order to augment the volume?

I have a B6100 with a FEL. Maybe you can do what Kubota did on the FEL side to run your backhoe. You can go to this post to see pictures of the setup. There are more pictures deep in the post. My tractor has no speed problems with the FEL but am not sure if yours has the same pump. If not maybe you can swap it.

Ken,

You can always fabricate a bracket to reverse the pump and use a chain or belt drive.

Good luck… that is one strong little tractor….

Ken,
The reason it is all backwards is that the engine roatates the wrong way. If you look at it compared to the B6100 you will notice the exhaust is on the left as opposed to it being on the right on a B6000.
That said I was told the gears could be fiddled to get it to rotate right.
On ebay it is not uncommon to see bidirectional pumps, you just change something to make it do the other way, that would work for you. you could always belt drive one off the front PTO (crankshaft).
I like the sound of your future plans, I hope to get a converted bus to live in in a hot sunny place some time. /forums/images/graemlins/grin.gif

Do all B6000 have this PTO or did they also have a standard PTO?

Thanks,
Maka

 

[GaryE]

Maka,

I am pretty sure they were all that way. There was noting in the manual that would indicate any different. It is possible in the last year(s) of production they may have changed it, but I do not think so.

Gary

Thanks much Gary.

Hi, super late response but I've got a B6000E with a FEL and Backhoe. I built a bracket and fastened a hydraulic pump to the PTO. Hub City sells an adapter that will bring the 10 spline shaft the standard six spline, I then used a quick coupler with 6 spline that slides over the adapter and the other end is a 1/2 keyed slot which the pump fits into. Bolted to my bracket and mounted to the bottom bracket of the three point. I have a tank on my backhoe. Digs super strong, I can go down almost 6 feet and I can lift 1500 pounds easy. I built a frame mount which ties into the loader frame just like the factory hoe did. By the way the factory hoe is a model B619, I copied the plans when building my frame mount. The tractor pump puts out about 1200 PSI, I am running around 3000 on my hoe, tractor pump is about 2.5 GPM, I am running 4.5gpm on hoe. My loader has a remote pump run by belt off the crank. These tractor's pumps are not really designed for anything other than THree point. Although I am aware some of the manuals will have you splice into the top of the hydraulic lift cylinder for pressure, I think the pump is just not up to the task.
Hope this helps others in the future.
