New Holland manual Spool valve flow

[essexpete]

Good morning
I have struggling to slow down the bed chains on a Teagle spreader. If I shut the speed down on the spreader control there is just a nasty loud hissing sound of the system seemingly fighting. The dials on the spools themselves seem to make little noticable difference.
Would any have some advice?
Thanks

Is the teagle or the tractor new to you? There was a thread on here not so long ago and pictures of how to match the oil flows and bed speed within the dial range to the tractor flow. Didn't know it was possible but there you go might be worth a look.

I first used the Teagle on an 8340, I am sure I could slow down partly on spool and partly on spreader valve. I used with the 6070 last Autumn, and now not sure, I was putting the muck on quite heavily.

Oops forget my ramblings was thinking tomahawk

The principle would the same?

I suspect it's not a brilliant system, I normally use a K2, but when I hired a Teagle once it came with a jubilee clip on the speed knob and a bolt sticking out of the face panel which together prevented turning it below 40% ish. I couldn't get much response in the remainder of the scale either, so I unplugged the box and set the (manual) spool flow on the (NH) tractor and tried to juggle forward speed.

Haven't gone for it again...

I think you are right, annoyingly I have just scrapped 2 machines that had flow valves on them. I cannot seem to slow down the flow with the spool knob. I will, as suggested above, check to see the spool regulator is actually moving.

You should be able to slow the flow down on the spool to a trickle, have you tried a different spool? If you restrict the flow too much on the machine you'll over heat the hydraulic oil in no time.

Yes, I realise that by noise it made when shutting down at the machine end. I will try a different spool.
