Operating Front Loader and/or Rear Links

[Tigger]

Hi all,

I have a 35 with front loader - the loader rams operate through a graduated turn valve (nearest the rams) and an OPEN/CLOSED cock between that and the Imola operating lever and return pipe.

The issue is that with the weight of a transport box on the back, if I lift this up, then open the valves to operate the loader, the box lowers back down, in other words there seems no way to be able to operate the front loader with a box attached on the back (and in the air), whereas without the box attached the loader works ok (but of course the steering is very heavy indeed). In fact with the box attached the only way to lift the front loader is to fully lift the transport box, once fully lifted the loader start to lift, but as soon as I let go of the operating lever the box crashes back to earth each time.

I have a feeling I might have read something somewhere about needing to hold the link arms up or down, or something along these lines, could anyone tell me what I'm doing wrong? I'd be very grateful!

You need the pick up hitch with locking bar to hang a weight on. You will notice it raises and lowers half an inch or so when you use the loader but being locked it stays in place.

You need one of these.

Small plate to be removed in front of the seat and rearward of the high/low lever. The diverter valve as above, fits directly on and the loader rams are plumbed directly to one of the ports.This valve will allow you to position the rear arms where you want them,then lock them and then use the loader without the rear arms moving.

better of if you can find an original massey selector valve and pipe the loader rams into the no1. ports that way the link arms will be continually topped up and wont drop

Hmm, that sounds like a good solution for times when all I would need is a weight on the back, I'll look into that way of doing it.

This could be the ideal all-round solution, when you say 'lock them' (the rear arms) I'm assuming you mean with the pick up hitch method? Would the loader operating lever be plumbed into one of the other ports, currently the feed for that comes out of the hydraulic case near the top underneath the seat?

All a bit of a mystery to me, the hydraulic system, but it'd certainly be handy to retain the front loader capability although I've toyed with the idea of removing the lot.

Not original, but something like this?

After some more digging around, a quick further question (sorry!) - would mounting a single port diverter valve on the case as described by agrimax, and feeding to the front loader rams directly, enable me to use the quadrant/lift arm up and down lever to operate the front loader too? WIthout any need for the current separate spool valve?

Yes, just the rear arms will creep down slowly, but if you can get the valve mf Andy mentioned they will stay up
You should be able to use the quadrant lever with your current set up anyway

The benefit of the genuine massey one is that it has a check valve to hold the link arms up when you are lowering the loader but will top up the link arms to compensate for leakage in the lift ram. It also has 2 common ports to connect to the loader rams so you don't need a tee piece

Ah, ok, things are making sense now.

So I suppose the question is, what does the genuine one look like, as I wouldn't know what I'm looking for?!

Very much appreciate the help given by all here.

No that's not the valve he needs

bad photo I know, but this is the best valve, it keeps the arms up

 

[Tigger]

That's very useful - where your finger is pointing is Port 1 (with Port 2 next to it?) and the selector lever is out of sight to the right of photo?

 

[multi power]

I'm not even sure what port is what, what I do know is if you connect to the correct port the arms will always stay up
@MF-ANDY @SMID @two-cylinder will know far more about it than me

Ports are marked. There are 2 no1 ports

your right, the ports are marked, but on mine there is a third port marked return or R, the others have 1 & 2 on them,
and unsure, but think the one pointed to in the picture is the return port

Yes i think you are right and one in front of that one is port 2. This will totally isolate the link arms although it has an internal shock valve to protect arms. Ports marked 1 are feeds to loader rams and link arms will top up but won't lower

The one the pipe is connected to the arms don't go up when the external service is used, not even when ram gets to end of stroke, I managed to loss the alloy decal which marked what port is what

yes ext 2 locks the link arms off. that is why there is a shock valve in the selector valve to protect the arms from shock loads as the lift cylinder is locked off from the internal relief valve when in ext 2. this shock valve can weaken with age giving the symptoms of low lift pressure. this is why i always replace the selector valve with a modifeid one in which i have locked off the shock valve.
