Mf 390t

[Huwie]

Anybody know the difference between the low profile and hiline cab on the 390t? Is the hump in the middle of floor of cab still on the hiline

 

[mixed breed]

Nope totally flat floor on the hiline, hiline + had better control layout too

We have a highline and uncle had a low profile. The last design of the 300 series. Both were the same in the cab layout apart from the hump in the floor

Didn’t they reposition the gear levers from the centre to the RHS?

that depended on the gearbox chosen, not many tractors after 1991 had the gearbox with the stick between your legs, most went 12/12 for loader work or 18/6 for 40km, however some 12.12 were 40km

 

[daveydiesel1]

Ours is 1 of the last mabe 95/96? Its 12/12 40k but we have 46 row crop inch rims on the back which leaves her a flyin machine. Pity shes not turbo cause shes wile dead at that speed

Any of the transmission options can be 40k

i knew the 12spd box could be converted but wasnt really an option for tractors here. 8/8 was hardly 40km. most of the 12/12 i drove were 1991/92 and 30km, anything i drove from 94 on was 18/6 and 40km.

I’m on the verge of bying a tidy 1996 hiline, trouble is its a 18/6 gearbox and not a 12/12! It’s hasnt got a loader but not sure how it would work with reversing activities like topping etc. Our old 290 was either too fast or too slow in reversing when topping even with the split

It will be fine for reversing, I never seen any problems with reverse speeds on the 12 speed syncro

I didn't realize you could have 8 speed shuttle in a 390

 

[Huwie]

Yeh it was the 18/6 box I was worried bout not the 12/12

 

[wdah/him]

Both ours had. Also both had the duncal cab and made in 1991. Only reason we had 2 was first was in accident. Its an OK box but very limited gears obviously

I understand the 18/6 is very good, the 12/12 is a disaster

Ours never gave trouble. We have a 390 and 2 4370s with it

12 12 fine on our 390 and 4370. Liked both on loaders. Moving to a 5613 with to many gadgets for my liking. Biggest trouble with 4370 has been front axle problems .

12x12 is great on 30kph tractors. On 40kph the first gear in high range is just too fast to pull away from a stop with any load behind the tractor. The main/only real issue with the 12x12 is a tiny little leaf spring on the range selector that has a tendancy to snap. Dirt cheap part but very many hours of labour to replace, because it is internal and things have to be dismantled to get to it.

The 18/6 is a far better gearbox for 40kph haulage and consists of a three forward, one reverse main box with a three speed range box to give 9x3, plus a Speedshift, on the go power-splitter which doubles the ratios to 18x6. Unlike later 24x24 boxes, this one did not have a hydraulic power shuttle and had a conventional dry clutch.

What went wrong with the axle?

Is the range selector different on 18×6 compared to 12×12

I've always assumed it to be the same but I've not heard of any issues with the spring on the 18/6. That doesn't mean that there isn't an issue though as there were never many 18/6 tractors in this part of the world and I'm just saying what my personal experience is.
