Hydraulic Top-Link

Doug Mc

Hi All,
I was thinking of getting a hydraulic top link as i see a good few tractors with them on. I think the should be handy for gathering bales ( if the ground wasnt that level) and stuff like that but was wondering if there are any disadvantages with them, other than the price of course.

i have one i got for a set of pallet forks on the 3 point i dont use it. (Secondhand was €100) I use the fixed top link for everything else. Keep it greased and its easy to change the lenght.

Alot of lads use them on the 9ft side mowers and for post drivers.

Don't use one unless it has a check valve fitted.

Have been using one for the last 6 six years here full time on the tractor, it was the very first thing I bought with my first paycheck

No check valve on it though, don't think they came with check valves the time I bought my one.

They are extremely handy for the bales alright ya won't know yourself

is it possible to source the check valves and fit to an old T/L ?

Check valve is unnecessary!

Thought check valve was really essential to prevent potential sudden and dangerous load drop in the event of a failure in any of the internal seals in the top link itself or indeed on the tractor itself!

Would the check valve work if internal seals went it couldnt stop oil flowing about internally. Theyre more for when a hose bursts i thought?

A check valve won't protect it against any failure or leakage of the internal seals of the hydraulic top-link. It will protect though against any of the hoses, valves or connections downstream of the check valve failing.

It should be possible. It's a 'pilot operated check valve'. That's the technical term. Any decent hydraulic place should have them.

Double Acting Pilot Operated Check Valve. Ideal for use on any double acting ram where the creep of that ram would affect the performance of the machine.

Top link fitted with a check valve

God that's a nice looking Hyd top link.

It's very important where the pipe fittings are located on the top link. I used a neighbours homemade job and it was very easy pinch an elbow on the tractor itself with the implement raised.

i got one for a link box for the spike for shaking out bales to the cattle it is some job now the normal one is just used for the haybob and the disc mower

Lads how much are they brand new say a double acting ram with a check valve??

You should be able to get one of those hydraulic top links for €180
