TO30 Loader Tilt Cylinder and other questions

I just bought a TO30 in good running order the only issue being the loader tilt cylinder. I have read a ton about them but have questions.

1. From the picture i uploaded, the front loader tilt looks super goofy on whomever attached the loader tilt cylinder, is this original? It currently is disconnected and looks like the cylinder is all broken. From what i can measure its a 16" long cylinder with a 1" shaft. But all the cylinders i find online have the mounting brackets on opposite ends, this one is right in the middle...I am thinking off just cutting it all out and just mounting a new cylinder in its place?


2. The previous guy has a shutoff valve next to the seat, if its open the front loader will operate, but the rear 3pt hitch does not, if the valve is closed the front loader does not operate but the rear 3 pt hitch does. Is this normal? Also when the rear 3pt is engaged it will go up all the way, but it almost sounds like it keeps trying to raise it though its to the max height. Is this normal?

3. Even with the front loader tilt not working it will go up and down, but it doesn't seem to have much pressure. I can't even lift my front end of the ground, is this normal?

I can't envision the cylinder mount, there were many different designs.

The valve that switches between the loader and the 3 point is a necessity. It directs the oil from the pump to either the loader or to the 3 point, can't operate both at the same time.

The 3 point trying to raise beyond the limit is a problem with the control valve adjustment. It is accessed through the round cover on the right side below the seat. I don't have the exact procedure, but someone can walk you through it or you may want to invest in a shop manual. Just don't reach in there with it running!

The reason the loader is slow and under powered is because the original belly pump was only designed to operate the 3 point. It doesn't have the necessary volume to efficiently operate a loader. They use small displacement cylinders in order to get some speed out of it, but in doing so it looses power.

You might want to do what you need to do to to get the tilt working, but if you go with a larger cylinder, it will be powerful, but slow. Once you get it working, try it for a while to see if it is going to be what you need.

A good loader system will have a separate pump driven of the front of the engine with it's own tank and valve system. That would be an option, but can get costly. The TO30 is limited in it's ability to handle a loader. The front suspension is a little light and lack of power steering makes it a real work out on the operator and the steering gear.

Thanks for the reply.


with the 3pth, if I have the valve turned on for it and the draft lever all the way down the 3pth stays lowered. If I move the draft lever up the 3pth raises. If I move the lever back down it does not lower the 3pth should it?

If I turn off the valve it will lower.

Will take off the access panel tomorrow to look around further.

If the 3 point works with the diverter valve off, then there is not a problem with the control valve. I would leave it alone, it is probably just a side effect of diverting the flow to the loader.

update, the guy before for whatever reason pinned the 3pt hitch to where the spring is on the top of the 3pt, it had enough slack to go 3/4 of the way up but that's why it sounded like it was under load. after taking that off, the 3pth goes up and down without any issues using the control lever.

I have the front loader all fixed with a new cylinder and everything is sort of functioning correctly now. The issue I am having is that if the diverter valve is set to the front loader. If the 3 pt hitch is not pinned to the spring behind the seat, the loader will not lift or go up, the 3pth will go up and down.

If it stays pinned and then I switch the diverter off, the 3pth will really push upwards and sounds like its putting a load on the engine, doing so I cannot lower the 3pth. If I unpin it the 3pth goes up much higher and then go lower without any issues.

This is a super pain to have to get off the tractor and pull the pin on the 3pt when I need to use the 3pth. I thought the diverter valve was suppose to put all pressure either to the 3pth or the front loader.

Fluids are brand new, and levels are accurate.

Thoughts?

Sorry for the double post above..

It seems like with the diverter to the loader, the power is being divided in half for the hydraulics to the 3pth and the loader. When using the loader I can't even have enough force to flatten the ground.

But with the diverter set to just the 3pth there is plenty of hydraulic pressure.
