JD 990-- Power beyond

[T HAUS]

Howdy. Couldn't get the search to work very well, so I will post up my question here.

Got an '07 JD 990 mfwd. 300cx loader. I'm wanting to run a rake in the summer and my log splitter in the winter. Tractor does not come with rear hydraulic connections, so I have been looking for power beyond so I don't have to unhook the hydraulics for the loader.

Anyone ever install power beyond on a 990?

Deere list power beyond for your 990 for $237. You will still need a valve. JC

Thanks JC.

Do you have any pics or links to pics which show the mounting of the control valve?

I installed a power beyond on my 990 mainly to use my log splitter. No need for a valve to use the splitter, and I can't speak to the rake. The kit is complete with hard lines, bracket, connectors and jumper hose. It takes a few hours to install with most of the time spent removing components to access the connections.

I don't have a 990, I just looked up the price on the Deere website. JC

I finally talked to my dealer and he said the same thing. No valve needed. It's just continous pressure to the connections. I talked to him about running a ground activated wheel rake. Basically just need hydro to lift the arms. He said power beyond would be no help for that. In order to run the rake, I would need to take the bucket off and use the hydro outlets that run the curling of the bucket to run my rake arms. I was under the impression that I would to completely remove my loader just to run the rake, and I wasn't happy about that. As is, I can leave the loader on and just unhook the curling hoses, leaving the main up/down hoses connected. That makes it easier to go unhook the rake and put the spear on and start loading bales while the baler is still running.
Other than a crappy location of the current hydro outlets, I have no need for power beyond. I can run some hoses to the rear for my log splitter (and rake)and save the $237.

With power beyond, you can add a valve and have a rear remote. Several have done it on 2520's because no rear remote is optional. Search in here or the hydraulic section. You can also add a diverter. If you want to use a log splitter, you will have to use your joystick to operate it, unless you add power beyond. JC

Just as RTR said,
You can plumb a valve to the PB loop, then you can power your splitter and anything else

The estimated cost will be about $500.00 not including the PB kit. I can talk you though plumbing it when your ready.

Gizmo I just mounted a koyker 140 loader on a buddies 990 I知 tring to plumb it into the hydraulics I致e tried all the ports under the seat I have flow but no pressure to run the loader can you tell me what I知 doing wrong what do I need to build pressure can I send me pics of how you have yours plumbed

It will be interesting to see if you get a response. This thread was last updated in 2007.

 

[Poorchop]

I see but there oughta be someone that can answer my question

 

[kennyd]

Here is what the OEM PB kit looks like, it sounds like you have plumbed the loader in parallel and not in series.

You really should start your own thread and include picture of where your are hooking to for better help.

There is a plug you need to install in the rock shaft for every thing to work properly. I have the hydraulic flow path in my post about mounting an aftermarket loader to a 790. The pics are from a 870/970/1070 rock shaft and the 790 type but I will bet that you are having the same issue I had installing the loader. You need to make sure of the flow path of the hydraulic fluid to insure not over pressuring the loader system. I installed mine backwards (PB to supply and supply to PB back to rockshaft) on the original try and will have to repack the bucket cylinders due to the pressure that was on the loader with out the relief system that is in the rockshaft that controls the pressure.
