Stump Grinder and M62

[refspd]

Hi Everyone! I bought a stump grinder for my Kubota M62 TLB and it arrived today. It's a Farmry HSG24 Pro which is PTO operated and has a hydraulic swing and an up/down cylinders. The unit has its own control valve and can be used on tractors with only one remote. I'm confused on the hydraulic connections. The M62 has three hydraulic ports. One for the backhoe, one for the swing cylinder and one return. According to the Kubota manual, after removing the backhoe you're supposed to switch the two hydraulic diverter levers located at the back of the tractor, into the "Three point position." Doing this routes the hydraulic pressure away from the backhoe ports and allows you to operate the three point. I need one set of remotes to operate the hydraulics on the stump grinder. Not sure if I should use the "Backhoe Port" and return or the "Swing Port" and return. I think if I set the diverter to the "Three Point" position, I won't have any hydraulic pressure at the ports to operate the stump grinder. If I set the diverter levers to the "Backhoe" position, I don't think the three point will work to raise and lower the stump grinder when moving from stump to stump. Is my thinking on this wrong? Will I need to switch the hydraulic diverter levers back and forth when moving the tractor? Any M62 experts out there who can set me straight? Any help or advise would be greatly appreciated!

I'd recommend getting the triple OEM remotes for your tractor, that way you only need to push in the diverter valves when the BH is off. The OEM kit costs a little more than kluging your own setup but everything fits nice and neat inside the cab. Note the levers fit into the space provided on your operator panel

Yes I thought of that, but was hoping there was a less expensive way of doing it. Looks like the kit is $3,300 at Messicks. That's almost what I paid for the stump grinder. That is a really nice setup you have on yours though!

Not to hi-jack your excellent discussion…(this comment is for those who came to learn about sump grinders because they have a problem with stump removals)…...but MY “best” method to get rid of stumps …has been to chain-saw the tree as close to the ground as possible and… (let the stump “die” if it was alive)… and when dry, … pour some diesel on …… then lay an entire bag of charcoal briquets on it and LITE IT!

It will burn for a day or two down into a hole in the ground.
All you have to do after that is push some dirt into the hole.

Cheap.

Works great.

Since you won't be using the 3pt and the grinder at the same time, switching the valve between the two when needing to move won't be an issue.

Having the correct valving on the grinder will matter more. It needs to allow flow when the valving isn't being used to keep from dead heading the system.

To get rid of my stumps, cut low, drill a few holes deep, pour this tree salt that dries it out and kills the root. Make sure you have a strong drill for that long bit. I burnt up 2 drills.

As I understand the situation you can currently have 3PH operation or flow to the backhoe. That makes good safety sense, why would you want to be able to move the three point if the backhoe is installed? Most (smaller) tractors route the hydraulics through the FEL valve and then to the backhoe valve. They require that the backhoe supply and return be connected together when the backhoe is removed so the three point hitch can be utilized.

I suggest you look into the operators manual or workshop manual to find the hydraulics system diagram or discuss it with your local dealer to get information. @TheOldHokie may be able to answer your questions specifically. I can only “suppose” from looking at parts diagrams. I could not locate the valve you are discussing in the parts diagram. I see that you do have a separate swing cylinder pump and I “suppose” that will be the circuit you need for any remote valve operation.

Here is a parts diagram of that piping and it shows a cover #20 that looks like it can be removed and replaced to divert the hydraulic flow out to a remote valve. I am assuming you have no rear remote valve already. I believe that you will need to buy a hydraulic take off block (or machine one) that replaces cover #20 in this diagram. See the thread below for a similar example of the cover block and the take off block on an older, simpler tractor to give you an idea of what I believe #20 to be.

I think we need a bit more info on what you want to accomplish.

With the backhoe removed the 3pt and tractor remotes work fine.

Now about that stump grinder. Why do you need tractor remotes if the stump grinder has its own valve?

EDIT

After rereading your post I understand what you want to do.

The backhoe has three hydraukic connections. One is supply to just the swing cylinder valve, one is supply to all other functions, and the third is tank return.

To use those for the stump grinder you connect the stump grinder to the swing cylinder supply and tank return outlets. You would keep the swing cylinder diverter in the backhoe attached position but switch the other to the 3pt position. That should give you what you want.
