Tank breather pipe blocked?A friend has a MF 4255, yesterday driving a double chop harvester with it. He topped up the diesel tank about 80-90%, after about 10 minutes working the tractor lost power and stopped. Diesel was flowing out around the filler cap and when He removed the cap diesel flowed out under pressure., the tank seemed to have pressurised? He syphoned around 20litres out of the tank, bled the system and it seemed to run OK after that. Any ideas folks?

Does the left pedal activate the trailer brake?One for the Massey brigade, I have a class arion 420 which has a Massey backend and the equivalent of a dyna 4 transmisaion. I think the brake system is the same from talking to a few people. Brakes work fine when pressed together or if the right side brake is pressed the right wheel brakes, but if the left wheel brake is pressed both wheels brake, it's very rarely an issue but if pulling beet or even spraying beet you might give the steering brake a little touch just to pull it into the row. This is the way the tractor has always been, any ideas?
Not sure must check tomorrow.Does the left pedal activate the trailer brake?
Left side brake brings on trailer brake. Right on its own doesn't.Not sure must check tomorrow.
That's what I thought.Left side brake brings on trailer brake. Right on its own doesn't.
Thanks anyway, we had an issue with brake switches when it came first but this sounds unrelated.That's what I thought.
There must be some feedback from the trailer braking system applying the right brake. I had heard about it before, but sorry I cant remember how it is sorted.
Is it a fault though? Is it not a regular thing that one pedal activates 4 wheel braking?
I've definitely driven something where the left brake didn't act as a side break, it could even be my own yoke, I haven't used a side brake on it in a long time. I must check.No i don't think so, left brake should only activate left rear, right brake likewise. Four wheel braking doesn't come on unless both pressed together. Otherwise there's no point having separate brakes. My problem is left brake is bringing on both rear wheels.
Yeah it's not something id use a lot, beet is really the only time it's useful.I've definitely driven something where the left brake didn't act as a side break, it could even be my own yoke, I haven't used a side brake on it in a long time. I must check.
Anyway never mind my idle ramblings
When I brake with both I'm not pulling to either side. And trailer brake cones on if both or the left alone are pressed what do you reckon is up in that case, the mechanism which activates the trailer brake? Is it allowing pressure across to the right side causing that to engage aswell?You should have a equalizer valve somewhere by the master cylinders
Usually the left works the left the right works the right etc
Then the equalizer valve balances the pedals to both wheels
Normally the balanced pressure activates the trailer braking
