hydraulic top link

Nertballs

where's the best place to buy a hydraulic top link in the midlands? looking for one that estends from 2' to 3' or around that and will be on a JD2650 for use with a power box.
thanks!

Im down South, Bought one today for 125 euro plus Vat. Its a Spurious make. Try Done Deal. or Vapormatic.

why would you need a hydralic top link with a power box? just use the hydralics on the box to move the top link closer whin hitching up.

I use one when cleaning up the middle of the farm road to adjust the lip to skim the surface and not dig into the road. Very handy yoke to have to do bits like that. Not brave enough to put it on the fert spreader though

I cant see what you can do with a top link that the powerbox cant do anyways.

If it was an ordinary transport box I'd understand but I'm lost at the moment

I'm thinking about getting 1 to use with the mower/topper so that we can easily change the topping height

anyone using 1 on a mower??

Am I correct in thinking that you can fit a check valve in the return line, to control the oil flow back to the tractor. Makes the hydraulic top link capable of dealing with the heavy stuff!
Could be dreaming though

Quick question on a similar theme. My power box keeps tipping slightly when empty and even more when full. The tractor is a MF 5455 and there is plenty of oil in it. I thought there was a check valve built into the spool valves but I must be wrong. So my question is what can I do about it? Do I need to fit a check valve to the box?

125+vat is cheap! I remember pricing one up afew years ago, 250quid or so, so I went down to the local scrap yard, got a ram off an old digger for about 40quid, and got two hoses made up for it (probably another 30quid or so, I can't remember). It handles silage bails no problems, which is our main use for it.

You may have by pass (leakage) going on in the spool valves!!

We have a vapormatic one for at least the last 12 years. Its great for the mower (8ft disc) or for the haybob. In recent years, it has proven very handy for the double bale carrier - especially on the New Holland as the lift arms tend to lift straight up as opposed to bringing the implement closer to the wheels of the tractor.

It never drops - even with 2 bales on the back of it.

is it a fleming box by any chance, my one dips a bit as well, not a great ram in them, that said mine is also on a 5455

Another thing to remember folks is to always compare like with like. Hydraulic toplinks come in all shapes and sizes... different length and diameter rods.

The eye can deceive. Unless you have the two hyd toplinks that you are comparing side by side or you have a calipers and tape with you, you're only guessing.

Central bearings in Athlone or there's a lad in Belmont that sells hyd toplinks

no, common misconception. The seals in the ram are probably bad, so oil is allowed from 1 side of the piston to the other, hence the the ram gets longer or shorter (depending which side the pressure is on)! an way to check if this is the case is to plug out the spools when it is on the ground, rise up the lift and see does it still tip by itself..

No its a 7' cashels box. Its not even a year old yet and hasnt done as much as I'd like to have done with it.

Thanks for that larthehar. I'll try that tonight to see if that is the problem.

I'd agree. Seals on the piston need a changin' if the ram is dry and she's not leaking from the cap or hoses.

Rovi

If/when the ram is stripped down and the seals are found to be damaged, don't forget to look for damage on the inner surface of the barrel.
New seals won't last long if there's an edge or nick of some sort chewing at them.
