Different engine, standard are 2 valve, premium are 4 which guves a more reponsive drive, 2 valve might be slightly more economical on light duties.. in theory. Premium also had a power boost. Difference in cab layout and finish aswell. Not sure eon gearboxes and hydraulics wouldnt be an expert.
Any engine problems I've heard about have been down to operator error, over revving seemingly being the number one killer!! Anyone who's had a 415 always seems happy with them anyway, as said finding one in budget will be the problem.
Smashing tractor
Can't do it with a cvx :Thumbp2:
The 5 is excessive but when your running a large amount of machines like that man is you nearly have to accept that not everybody is going to be able to drive them properly.
What didn't you like about the 415? Always thought they seemed to go well, looking from the outside anyway.
I believe so with the ones here, you hear them slowing down at junctions and they seem to be revving extremely hard on times.
There's no problem with using the vario to slow down as long as you keep the engine revs from rising too far, exhaust brake and keep nudging back on the joystick to keep engine revs up is fine
A friend of mine would skin anyone alive for using the vario to slow down on his Fendt. The tractor alone is fine but any trailer work use the brakes. I know very little myself just what he told me.
Weren't the 20 series autopowers badhttp://www.nethertontractors.co.uk/equipment-sales/tractors/s6420s.html

Surely to God there is a training course or even a manual explaining what you can and can't do. At least on the fendts??
That isn't strictly true, all cvt transmissions in tractors have a degree of mechanical drive at some point through the speed range. Not sure on a fendt is it 100% mechanical at top speed then it reduces as the speed drops?? On a cvx there is four points from 0-50km/hr where it is purely mechanical, this is around the middle of each range depending on engine revs. If you take your foot off the pedal on a cvx it will gradually come to a stop, it doesn't try and stop instantly the electronics prevent that from happening, it would match forward speed of the transmission to engine revs to prevent it over revving. Where as in a fendt pulling back on the stick your actively slowing the transmission down, bit like in a normal gearbox if you changed down a gear while going downhill the engine would over rev.
bit like the tm then. damn tractor is the worst for it. when i'm going downhill i try to get the tractor under 1500 revs before down shifting, go into 17th gear from 18th and she goes up a bit to 1800 but most of the time when i get to 16 or 15 that 1500 jumps right up to 2100 and by that point my foot is still on the brake trying to slow the engine down. id say i have to drop down to 1300rpm to have it not over-rev too much
