Jcb agri super help

[Highashgrange]

Hi, we’ve borrowed a Jcb agri-super from a friend and are struggling to operate the gearbox. We are manitou people with very little Jcb experience. My friends away and not contactable so any help much appreciated.
I’ve attached some pics of the cab controls but basically it’s 6 speed but with only 4 positions on the left hand reverser stalk. If it’s in 4th then it will automatically shift up to 5th and then 6th.
Problem is when it down shifts it’s a hell of a bang and jolt. Also we are loading straw so want to stick in 4th in the field without it auto shifting to 5th and 6th. So is there a way to run it in manual all the time?

Press the button with the 3 gears on it until the gearbox symbol with the ear of wheat for field mode comes up on the dash board. That will stop it going into 6th gear. The switch is underneath the boom suspension switch

Thank you. How do you then manually shift into 5th and 6th if you want to run it manually all the time?

you can’t run it manually in the higher gears. Mine works really well in the field.

A TM310s might be the same

Usually run in empty trailer mode and don't be as heavy with the right foot and it'll not change up to 5 and 6

Well what a horrible gearbox. There’s 4 of us and none of us like it how it operates. It’s prehistoric the way it shifts gears compared to our two manitou power shifts. It’s got us out of a mess which we’re thankful for but there’s no way I’d ever part with money to own one. Two Manitous to change next year and Jcb won’t be on the demo list.

New ones are far better I used to like that box till we got the newer type which I wasn't keen on then got a ten yr old 310s and I now agree with you it's shite .

That said I'd still take it over any manitou I've used

Even the old manitou power shifts were better than this thing. There’s nothing smooth about it. I even had a local mechanic call in just to check it as I didn’t want to exaggerate a possible problem but he said those gearboxes are all like it. The rest of the machine is ok though although I do find it physically big compared to the manitous and a merlo we’ve already demo’ed.

I like that you sit higher in the jcb you can see the back corner better .

I occasionally have to drive both merlo and manitou and just can't take to them .

My 310s only time it's out of 4th gear is on the road really so don't really notice the jumpy box but yes give it too many revs running around the steading and you get the clunky up into 5th and back into 4th!!!

Coming down the box is worse than going up with this one. As you say 5th to 4th is bad but also 4th to 3rd. The hydraulics are as quick as the Manitous but that’s just an age thing as they are much newer.
We really liked the Merlo 38.10 though. A lovely machine but we are concerned about the warranty as we want a 5 year 5000 hour so the dealer is looking into it with merlo at the minute. We’ve got the manitou vario coming out soon as well and then also a claas and Kramer to look at.

How come you were down to 3rd ?

Just looked I assume you had it in loaded trailer mode I always run in empty like in the second pic

I'd certainly not write it off all together without trying a new 1 just because of an old well out dated gearbox no harm in trying a demo

That's an old 6 speed box gears are on the joy stick with a torque lock in 5/6 at 20 k

They are crap because jcb wont fit modulating valve to the clutches which manitou have done on all machines since the early 90's even on the non powershift boxes they have modulation valves

You might not like the manitou vario. If you dont you can get the same 6 speed box in a new manitou as that's not really changed in the last 20 years!
If it not broke dont fix it
