JD baler losing pressure

[Monty]

I was baling round the outside of our main silage field last night to get it out the way before doing the middle today. I got 51 bales 3 times round 30 acres!! We had 36 outside bales from the first cut so there should have been about 25-30 judging by the grass. Bales are coming out very soft in the middle and the pressure guage keeps dropping off steadily as the bale is forming. Any ideas where it's leaking from? This is a 678 combi based on a 578 baler

Somebody will know about your model but my 550 (I think) will do this if any of the ram seals on the door are shonky.

Aha. Think I've sorted it. Loose hydraulic hose. Fingers crossed
