Fendt vario drive

[FendtRunner86]

What have lads found the best running transmission percent for transport work?

 

[Suckndiesel]

14% is what is recommended in the manual of the older ones iirc

 

[Boysground]

It all depends on what you’re doing, 14% was always the starting place. These days if i am just pootling around with something not massively heavy i will leave it on auto. Alternatively if i my need a bit of welly and want to keep the engine speed up i will drop to 10% as a starting point. So the revs drop 10% before the gearbox makes a change.

I tend to run the acceleration rate on 3 so not a boy racer, and I avoid silage trailers if i can. I drive too slowly over my bumpy fields. So I am definitely not a boy racer who has to be everywhere yesterday.

Should add i have 724 and 716. Perhaps the bigger machines behave differently

I'm not 'Fendt literate', so apologies if this is nonsense....

.... But isn't fendt transmission percentage their fancy name for what every other manufacturer calls "engine droop" ?

That’s it

Question from a non fendt man . If there's an auto why would you need to move the % ?

 

[Fendt65]

I point mine and drive i love being called a boy racer though.

Depends on what way you want it to behave. Say on a forage harvester you want the revs to stay up so the transmission will slow, but mabe your spreading slurry where ground speed is more important than revs so let the engine die a bit before pulling the speed

Only asking as with jd you can do the same but very very rarely need to .

I seem to remember from my youth that tractors had 2 metal sticks with black knobs on that protruded from the floor and ended up between one’s legs (making it difficult to get into the cab!). Stirring said sticks about provided a suitable forward speed, while another little metal stick set the engine revs.
Then nice Mr Ford added another little stick on the side of the instrument panel cowling which allowed one a change on the move Hi and Lo in each speed, (and unlike certain competitors, the tractor wouldn’t run away in Lo).
Then nice Mr Deere sent me a tractor with red knobs set to my side with a change on the move Hi and Lo AND synchromesh between 2 sets of gears.
Progress??? All far too complicated and expensive these days I fear…….

Aye, and there was only grip from the back wheels, and then only if the diff pedal was heeled fast enough

It doesn't seem that long ago !

But in a day I'll get far more ground covered and work done sitting in my plush 4wd, flight deck controlled Vario, than the old eight speed ford floor shift (never had the wee lever on the dash here, but still have nightmares about hills, and that tee handle in the fergy 135 )

Nostalgia is wonderful, but not as wonderful as the comparative luxury from all these buttons and computers

I tend to run in auto mode myself... some of our drivers think 14 to 17 % gives them an edge on the road.

Yea that’s what we run AUTO for transport. I had a fellow tell me he thinks running 10-14 percent makes a difference but I never noticed much. Was curious what others thought on the matter

 

[Boysground]

For transport it’s not a big issue. I change it to about 10% for fertiliser and spraying, it just holds the revs better on the banks. For the drill i will go down to 5, again if i need welly to get uphill.

[Chae1]

Probably doing it wrong, but I just adjust min and max rpm in TMS settings, when ploughing and struggling for grip I shut the max rpm down, so when grip limited it doesn't give it a load of rpm to try and maintain set speed.

Generally have aggressiveness at 2 ploughing, had it on 3 muck spreading. 4 must be pretty aggressive, haven't tried it on it yet.

Ah, nostalgia isn’t what it used to be…….

I grew up, learned to drive with 2 gear sticks between my legs. Moved on to the red tipped levers on the right. Now drive a fendt vario. Enjoyed every minute of it mostly. Wouldn't go back to those days. Progress has been good for operator comfort.

Also controls the power split between transmission and pto.

What percent you run on the triples?
