I'm new to the forum and just found your post.<br>
The fact that it works normally with a 'cold start-up' might indicate more serious problems than you would like.<br>
These tractors have the hydraulic filter inside a canister just below the right side running board.. in addition, they have a pick-up screen in the bottom of the transmission/rear end case. From the filter canister and toward the rear of the tractor, you will see a plug (approx. 1 1/2 inch diameter) that has a square hole in it for a half inch ratchet to fit into... remove that plug and pull out the screen...if you have trouble pulling it out, go straight across the housing to the other side and remove another plug....you will then be able to bump the filter out with a long bolt or punch....the filter screen is probably 10" long and about an inch or so in diameter. If you didn't know of that screen and it has not been cleaned in a long time, you could have minor problems, but not likely. What happens most of the time is that for whatever reason the brake linings will come apart and cover this screen, causing the hydraulic system to 'starve' for oil. When the tractor sits not running for a while, that stuff will tend to fall off the screen and settle back to the bottom of the housing, so when you start up it works fine again until it pulls that trash back up around the filter and starves out the pump.... it doesn't completely cut off the oil, but it will restrict it enough to cause everything to giggle/jump. Many times I've had people tell me that....well my brakes seem fine...that can be the case and the linings still be completely gone, so just because your brakes act like they always did, doesn't mean the discs still have lining. <br>
This is probably your worst case senerio and since it's been a while, maybe you've found something much more minor causing your trouble.<br>

2030 Hydraulic Problems

The 2630 JD has a closed center hydraulic system and does not need a 'power beyond'....in fact there is no such thing as 'power beyond' with this type system. You can get hydraulic pressure anywhere you can tap a pressure line and you will not have to worry about a pressure relief valve....this particular pump has it's own built in. You never said, but does your log splitter have it's own control valve for the splitting cylinder or are you wanting to operate that cylinder with the tractor remote lever? I'm assuming it has it's own, otherwise you shouldn't be having the problem you describe. A cylinder is a cylinder and has no knowledge of 'open' and 'closed' center hydraulics....control valves are a different story and will have to match the tractor system to function properly. One way you can usually tell (with a valve that was taken from another application) an open center valve is, it should have had 3 hoses connecting it to the tractor.... one would be a pressure port...one is a return to system pressure....the other is a low pressure return to sump. A closed center valve only uses two hoses...one pressure the other return (low pressure). If your splitter has it's own valve, there is a chance that it is one that can be converted to work with either of the two system types....you would need a special fitting to go from open to closed. If you know what brand valve you have it shouldn't be hard to locate that conversion fitting.
