Massey Dyna VT v Dyna 6.

[DeeGee]

Is the VT transmission reliable and durable?
Tempted by VT but I notice that used prices seem to be slightly less than comparable Dyna 6 models.
Be looking at something like 2015-18 models about 160-200 hp.
Any opinions and experiences welcome. TIA.

Vt all the way

Vt all the way

Can you say why, and I take it that there are no inherent problems with VT?

I've had seven VT's since 2006, three new, four second hand:

2006 7480 new, left with about 12,000hrs, on original brakes, gearbox, engine. Had a gearbox wiring loom, hi low cable and engine loom. under 50p/hr total repairs

Replaced by a 3yo 2015 7618 with 1500hrs thats actually better still. Its done 6000hrs now, and has had an exhaust temp sensor, alternator and a pair of batteries. Thats it!

2006 7495 s/h 2700-6200hrs left 2013 - the one that got away, should never of sold it, super tractor. Sold because a staff member wouldn't drive a VT and wanted to keep the 6490 that was at the time the newest tractor on the farm. It was replaced by a new 7620 in November 2013 left in June 2021 for a 7720 from the same home as the 7618. 7600hrs and very little bother that I can remember bar odd trivial stuff. The 7720 has a different back and and eats solenoids but is quiter and comfier. Its only done 3000hrs so far.

When the dog of a 6490 finally left it'd clocked 7000hrs and had £28,000 spent on it in transmission repairs. It was replaced by a new 7620 VT in 2015 that we still have, now on 8000hrs. Its the only one to of had a replacement gearbox - 300hrs and 10weeks from the end of warranty.

In 2019 I bought a 10,000hr 7490 as an extra to replace a hire tractor and provide backup. Paid £17k for it. Now on 11700hrs. The only one we have that sounds like a proper tractor!

We also have two 6480's, though one is a recent addition. We've been into the 2010 one, but thankfully not to 6490 levels.

My opinion? If its over 150hp go VT. Nowt wrong with a 6480 as an any driver runabout cart tractor (as ours are mostly) but the D6 box isnt up to heavy draft and big hp.

For spraying, drilling, potato work I wouldn't be without my VT - I drive the 18 and 7490 mostly.

VT's are cheaper because people are scared of them, somehow thinking a powershift is somehow simpler and more reliable. Absolute tosh.

Funnily I could never get on with a VT on draft work, the lose of power is shocking, for everything else they are way ahead, but put a big plough or grubber on it and they are dead to the world. Any independent tests I have read say the same thing, well able to compete till you put it to heavy draft work, 12/15% extra power lose over a Dyna6.

The difference is grip - a well set up VT will out grip a powershift evry time. A D6 will chew and rev and spin but won't actually get any more done with the same hp

Do the Massey VT tractors come with radar speed/slip sensor?

Been ploughing (wet!!!!) ground with valtra's Vario 'box which have radar as standard. The grip from the Vario tractor is astonishing, but the lack of "slip" is even better. Instead of spinning wheels and sinking, it reduces torque and speed to the wheels, then if set, it automatically lifts the plough a little if it's still struggling to get through


If it's solely transport work, and the tractor never entered a field, then a fixed ratio gearbox will be better for both performance and fuel. For everything else, there's nothing as pleasant as driving a Vario of whatever denomination

 

[ColinV6]

Do the dyna VT sit stationary when in drive like the CNH vario gearbox? Cause I drove a John Deere 155R the other day with auto power and didn’t like the way it always crept when in either forward or reverse.

Had to use the brakes to hold it, and no exhaust brake either!!

In pedal mode with foot off the pedal it'll stay stationary yes. In stick mode it depends where the start up speeds are set

Yes, in a nutshell

Early ones worked on the cruise settings dictating a wheel speed (as a fixed ratio tractor would) 76&77 series achieve a forward speed regardless of terrain, which is better.
You can adjust the amount the engine dies back before it adjusts the transmission too. I don't find I need to use slip control much, but it's there if I do

Jd with command pro joystick does not creep. I have never understood why the creeping gearbox was allowed. Dangerous in my view. It’s even worse when you have tractors that do both, I did it’s confusing.

Well yeah it was only a short drive I had in a contractors tractor to see what all the fuss was about with them, he was showing me the quick layout and I put it in forward and just let my foot off the clutch like I do in my autocommand NH, and I just about sh!t myself when the tractor started going forwards. Very unnatural especially with sharp trailer brakes when your approaching a junction.

The suspension however was incredible on it, and the gearbox very quiet inside compared to the pretty whiney new Holland box.

Only driven Nh a few times so not a lot of experience with them. Running both Fendt and Jd it was a pain when one would creep and one not. Now on my 2nd 6250r and that is so much better and definitely safer. Personally I drive a Fendt 724 most of the time, which is a great machine, I have always felt the Fendt suspension more smooth than the Jd.

Definitely biased to not having gears here, don’t have a tractor with any. Even the kubota on the yard scraper is hydrostatic

Jd IVT command pros here and they don’t creep! I Never use clutch or shuttle!

The only time you need the clutch in the New Holland is when you’ve been off the seat.

 

[davidroberts30]

Only time in my 74 is to start the engine

 

[vantage]

If my tractor hasn’t moved for a short time, handbrake automatically comes on, then you need to dip clutch when you push shuttle direction. Good idea, but can be a pain when on the feeder wagon.

That statement makes no sense to me..
