Fliuds Drain Farm Pro 2430

OK, Just getting ready to do much needed maintenance
I have drained & changed Gearbox & ready to change engine oil & hydraulic oil
I found drain for oil & 4x4 axle, but I don't have location pin-pointed to drain hydraulic at 3-point (Rear)
Looks like a remote stub on the right lower side (Looking From Back), but I am thinking that is return access.
Can fluid be drained there, or do I need to vacuum out at inlet/fill site ?
Thanks, (WAITING ON SNOW ARMEGEDDEN)

Not quite sure why there's not an actual drain plug, you'd think that was an engineering basic. I haven't personally owned a 30hp Jinma, but I seem to recall a discussion about having to temporarily disconnect one of the hydraulic lines and use the vacated hole as a drain. If memory serves, it may have been on the right side rear when working from the back end of the tractor. Whichever connects lowest on the sump anyway.

I have a Jinma 354 and there is no hydraulic drain. I change the fluid using an oil extractor pump, it's easy if the fluid is warm. I have heard that an easy way to drain the fluid is to disconnect one hose from the steering cylinder and spin the steering wheel.

Dunno if yours is the same as my 204 and it's been a few years since I've done mine so take that into account LOL. I seem to remember there was a bolt in the top link mount or something that would drain it, I think. I do remember it was messy as anything as there was no way to put a funnel or anything under it, I ended up using a oil drain pan and letting it run down over everything.....Mike

Looks light a great place to drain & not messy

If your tractor is like mine I think that's the hookup for a single-acting cylinder. There's a knob under the seat that controls whether fluid goes to the 3-point hitch or this cylinder. They share the same controller. The fluid direction is determined by the position of the control handle and the 3-point hitch: if the hitch is lower than the current position of the handle (ie if fluid would flow into the lift cylinder if it wasn't diverted), fluid flows out. If the hitch is higher than the handle position fluid flows back.

So in the outbound position this hookup is attached to the pressurized side of the pump. Opening it with the engine running would empty your fluid in a hurry, but I wouldn't recommend that. In the inbound position it's connected to the sump. I don't know if it's a straight connection or if it would drain. You can certainly try. One warning though: to get it into the inbound position, what you have to do is lift the 3-point hitch, then turn the diverter knob, and then lower the lift control handle. Do not do this with any weight on the hitch! In order to turn the diverter knob back to the hitch lift position you need to relieve any pressure on the hitch. If there is weight on the hitch you will find yourself in a catch-22 position where you can't turn the diverter because you need to lift the hitch, and you can't lift the hitch because the diverter needs to be turned.

Well, I've got all the maintenance & fluids change done, except for the hydraulics, even cleaned the fuel tank & radiator.
quicksandfarmer,
The only valve,(in front of the seat) this one has is for regulating the 3-point down speed,
If I raise the 3-point, then tighten the valve, then lower the handle, this will relieve pressure ?
I had a newer Foton that had 2 remote hookups & they were on the left back, I had a 24hp Jinma that this port/hookup location was to a FEL
This 30hp has 1 remote on the left & this pipe (Picture) on the right
I sure don't want to get hydraulics messed up
A local guy has a Jinma 304, & I will see if he's drained his hydraulics

We drain them by removing the Return line with the quick connect on it, left side looking from the rear of the tractor.Just take the bolt out holding the return hard pipe on

The black pipe on the right sure looks like a drain. I don't have that on mine and I have the single-acting remote on the right, not the left like yours.

The lift speed adjustment is the knob I was talking about. If you turn it all the way so the lift speed is zero then the fluid goes to the single-acting remote.

What Tommy said would work too. I didn't think to do that because I'm reluctant to take things off when I don't know what i'm doing...
