MF 7400 questions and answers

[Antares 6]

What is this box on the left side of the engine ? as you can see i have a litle leak from the top of it, you can see the oil on the hose.

@davedb Has a t2

 

[Antares 6]

Yes it is a T2.

 

[Antares 6]

One more ))
Look at the 3 photos, i have now open up this meny, i understand what the first column does...blue circle.
Photo nr 2, i do not understand what effect i achieve by adjusting the pedal column, appreciate an explanation.
I think many 7400 owners are grateful for their help

Red circle is how fast the gearbox responds to you lifting off the throttle in pedal mode. With one bar showing as it is it will slow down slowly. With all four sowing it will slow very aggressively, in my opinion the third and fourth bars make it almost impossible to drive at road speeds as they make it over Rev the engine to easily with the slightest lift of the throttle pedal.

Tommy...thanks, now i understand why i over rev when i go off the throttle downhill, i have had this on 3 and 4, will now try it on 1 and 2.
What about the blue circle/pedal, how does this work in real life ?

 

[davidroberts30]

Blue circle is how the forward reverse shuttle behaves
1 bar slow reaction 4 bar fast reaction

 

[davidroberts30]

The SV line (between the blue and red circle)
Is how fast the sv1 and sv2 buttons react

 

[Antares 6]

The blue circle...so on 4 the tractor will react quicker/shift from reverse to forward quicker than on 1...or with other words, when i shift from reverse to forward the tractor will start to move forward quicker with less delay....correctly perceived ?

That’s the breather filter probably just leaking on the o ring

Yes i saw it was a lid on the top with an o-ring on, i notice that the o-ring was flat/worn so i will replase it.

Yes, 4 will be the sharpest change. 1 the softest,

Thanks for all good answers to all of you, i now start to understand this "data tractor" thanks to you.
I am sure there will be more questions ))

 

[Antares 6]

Is there somewhere in your contry it is possble to buy used MF parts ?
Ex a grille ?
I need a complete 7400 grill.

Do you mean how long time/many seconds i need to hold the SV knob in before the SV kicks in ?

no how quick it reacts to speed once you press it

as an ignorant old git can i ask are all the modern tractors as complicated to set up? it looks as if more time is spent programming than driving. i realise that once set up they are more efficient/less tiring to drive. cue cowabunga?

I think no, the young generation have NO problem with this newer tractors, but when the driver are like me...55years old and never have drive tractors with this new tecnology i think it is normal to have a "brakein" period, i have no problem with 90% of it, the last 10% i would figure out, but with the help i get from experience drivers here i gain alot of time ))
I would NOT !! go back to my MF 3000 or 6100 serie now after i learn this 7480 to use, love it.

thanks, my post was not a criticism of you but just a general observation.i was asked to go on my old sprayer for a couple of days after a ten year gap and i had difficulty at first remembering how the computer box worked. i'm 74.
