    Wise Buy? High hour MF Dyna VT

    Currently got the hots for a 7480 with high hours. It's cheap enough but I've heard horror storys about the fendt vario transmission and five figure bills when they go wallop.

    Should I be worried, or even consider such a tractor.

    Or should I invest a bit more and get something newer?

    I know nowt about running these tractors so testamonials would be appreciated.

    They have the potential to run for very high hours. Indeed indefinitely like Trigger's broom. But it depends on good maintenance, good driver, sensible work and luck.

    Service exchange transmissions are available at sensible prices compared to some. The job of changing it isn't too bad either. But there is far more to it than just a transmission and all the usual wear and tear items still apply.
    Considering that a new equivalent today probably costs around 70,000+ then a high hour one in the mid 20's would possibly be a sensible buy even if you budgetted about 15k over three years as an insurance type contingency for repairs that might never be needed.

    How old 7480? I have a 2006 tier 2 model with 7700hrs, here from new, worked bloody hard really, though same driver for most of it. Repairs to date pretty minor, tell you more later, off out now.

    Has it been dealer serviced and has it service history? How many hours?

    The reason i ask about dealer history as the rear brakes are adjustable and often overlooked this can burn out the cardan brake at high hours taking the vario with it (or at least it does with the Fendt)

    Looks tidy and well priced. Maybe contact the previous owner about the history. Should be able to get their details from the v5 if you can get a look at it.

    Bit more expensive but both look good! new shape t3 engines = more power!

    Nearly double the price. Still only half the price of a new whatchumycallit model though. Would the new one be a 7615?

    Would you buy one over the dyna6 version considering the extra expense and no power-boost? I personally think they missed a trick by not effectively rating these permanently at the higher boosted [equivalent D6] power rating rather than the lower power. But what do I know? I'm only a potential customer.

    I am but a poor, simple lad looking for something better in the field than my fastrac. Money is a big factor at the mo as I want things to pay for themselves.

    http://www.pvdobson.com/includes/veh...s_farm&id=2748

    I went to see this a few months ago when they were asking 30K for it. Salesman was talking silly money to swap so I walked away.

    I just can't get over why 10,000+hr fendts are commanding such big money - there MUST be confidence in these transmissions.

    They use the same transmission exactly. Same hydraulics and back axle as well. Different sotware and cab and front axle, that's all.
    I love my 7490 and it has been no trouble apart from the radiator fan couling. It has only just crossed 3500 hours but works very hard when it does.

    Mine has a bigger transmission compared to the 7480 but actually the 7480 won't be far behind in performance. One problem I forgot about on mine is that EP90 from the rear final drives leaks through the diff oil seal into the transmission. I just keep an eye on the levels and change the transmission oil more often than specified in the book. Some fine day it might be fitted with the available modified seals.

    Had a 2007 T3 7480 for 4500 hour, only had one injector fitted.
    Also a 2007 T3 7485 had that second hand, had a few jobs done to it, nothing that stopped it, that went at 5200 hours.
    Now have a 2012 7485 with 700 hours on it, only thing wrong is that the dealer can not get the hand brake to work right.
    Found the 7480 low on power for road work, good in the field.
    Found the 7485 good on the road, very good in the field, but a bit big on the headlands.
    Found when selling the tractors i could not get the money for them that could be had for the same JD. The JDs were the same money to buy but worth a lot more when it comes to sell them.

    That's strange! http://www.robsontractors.co.uk/details.php?id=2400

    This auto power 6930 seems very similar money to equivalent 7480.

    I was told this too hence my previous post about the brakes it's to do with the MF software on the fendt transmission, a local contractor has had major problems nothing wrong with the tractor probably a combination of poor trailer brakes and the nut behind the steering wheel.

    On the most savage setting, the Dynamic brake will just about lock the back wheels just by taking your foot off the gas.

    Are you sure he didn't mean dyna 6? Engine braking non existent on my t3 6480 it's shocking.

    Offer 2K less for help towards tyres that you pobably wont replace for a bit then get her bought, keep the oils right she should go a long time yet, we never sell MFs with much less than 12000 hours all be it we have never run one of these, but would think she'd be right

    Depends how you have it set. Too harsh and it will throw you up the window with the engine braking.

    For the record 07 7485, 5000 hrs. Couple of minor faults but wouldn't swap it for anything.

    The engine braking depends only on the transmission ratio and the type of engine fitted and its characteristics. In pedal mode the rate of transmission deceleration can be adjusted but too slow and you will feel that it doesn't slow down fast enough and too sharp and it will tend to over-rev the engine as it accelerates over compression faster than the transmission slows. I don't like or use pedal mode on the road but find it useful when following a forager in the field.

    For the same fixed transmission ratio there is no difference whatsoever between the engine braking of one of these and a stepped mechanical or powershift transmission. I cannot emphasise that enough.

    The salesman for the local Fendt dealer suggested that heavy use of transmission braking is likely to be a cause of early vario failure, is he right?
