You will have little bother with a 7718 especially a farmer owned machine.
I know of ones with high hrs and no gearbox trouble.
On the large frame 7720 upwards 3rd gear can fail.
You will usually tell when it starts to crunch or rip selecting 3rd gear.
If its got in time the repair bill is modest
It is a relatively easy job when done in a timely fashion. The rear section of the gearbox, which is the four speed robotised synchromesh range box, is removed and repaired on a bench. Special tools are needed but a competent mechanic can make his own switch box. It is all tested on the bench using compressed air before being reinstalled in the tractor and buckled up.

Don't run it with a dodgy sounding range box for long or components will really fail and fall into other rotating parts and ruin the thing, which will be a very costly mistake. I always hold that if something isn't broken, don't repair it. However if something is obviously broken, repair immediately and properly before it causes collateral damage and much more cost.

A Dyna E-Power is not the same thing as a direct drive... The E-Power was twin clutch's on the range box on the powershifts
Is there a video or illustration on the web showing how this works. Although I run a DCT transmission on a car, I reckon there's far too many synchromesh units and associated wearing items on this type for tractor use long term. I am open to persuasion otherwise though.

So it is very much the same as a direct Drive except there's no noticable range change... Right....:scratchhead:
Tractorman will have to explain how that means there is "nothing like the Dyna E-power on the market" because that's essentially the same thing.
Sounds to me that it just has a powershift unit a range box. The DCT part is probably like any other DCT in principle. It will be interesting to actually see how it works in an official video, which I'm sure will be made.

DD isnt all plain sailing like they all tell you neither.
good luck with masseys latest two 28 fixed gear trans.... they had 32speed 30+ year ago it seems they have made great progress since :scratchhead:
The original Dynashift had a whole lot of overlapping ratios of course. This new one probably has a sequential gearbox which gives at least as many practical ratios with no mechanical range shifting and certainly none that require a break in drive and rowing a gear-lever around.
Hopefully they will have though of providing a way to skip-shift by seamlessly missing a flexible number of ratios when changing, at the driver's whim and command.

Them Fendts should have just had MAN engines in from the day they stopped fitting the MWN wasnt it back in the 80's ??
There must be some legal spegal tied up with the homeland that its pretty much gotta be a home produced engine in them iam sure of that
thats if its all possible of course. who knows.

Deutz is a descendant of the MWM engine and is built at the same location. Deutz took over MWM offroad engine factory. So basically you could legitimately say that the Fendt has continued to use MWM engines but with a Deutz badge on them. I agree though that they are not as reliable as they once were reputed to be. It's a bit much to expect engines to be the same today as they were in the 1980's though, because everyone has had major redesigns since then.

Well that was not our case , one minute is was all good the next no 3rd gear, no warning no noise, just bang no 3rd gear & this was the case 3 times & every time the gearbox had been tested with air & on a test bench & worked 100% but with is 37 hour it was to take out again & this is not a 5 minute job , In the end we fitted a new gearbox which is what MF recommend now as the old one goes back to the factory , as the fail rate of repaired boxes is very high for some reason , it must do some thing to them .Thank you for words mr Duck but 3rd gear is not a cheap fix

They should be better nowadays but and not less reliable. If thats the case whats all the educated folk bein paid big salaries to design this stuf doin?

Was the 7700 a different gearbox, or more reliable box than 7600?
Or what was difference in 7600 and 7700

Got a friend who runs fastracs for his contracting business. He was here last week in a brand new MF 245hp which was on demo and his words were ‘this is going to be hard to beat’. That’s coming from somebody who has run Fendt and deere previously as well as the fastracs of which he currently has 7 4000 and 8000 series.
It was a big tall tractor for 245hp but I liked the fact the cab wasn’t connected to the bonnet and the ride was silky smooth on par with a fastrac. All in all a very impressive tractor. That particular model was verbally quoted to him at £115,000.

For £115,000.00 it would be hard to say no. That is a very good price!

Yes, but this is why too many S/H MF's are lower spec, no guidance, not even steering ready, no front PTO or F/L sometimes, poorly shod, non-climate control!

By the time I've gone through the list of required spec from a base tractor it is £30k extra.

Probably not by accident either.

You have to remember the parent company and how they are positioning the brands. Whilst also using a mix of similar components across ranges within those brands.

Time will tell if it’s successful. On one hand it’s three brands giving perceived rivalry with AGCO the ultimate winner, on the other its a lot of bickering about MF v Fendt v Valtra whilst JD continue to top the lot, and CNH push on with new models/transmissions too.

It'll be interesting to see if he buys it
