John Deere direct drive gearbox?

[livestock 1]

The chap I spoke to said they have very little trouble running them to those hours. A lot of pipes burst around 10k hours. Still get over 20k for them with those hours. They'd be doing 2.5k hours plus per year. So only 8 years old.

I’m just always getting told what hours the plant gear does in the quarry next door 20/30 000 hours is no big deal to them. Warranty is for much longer. The lads laugh at us with ag gear packing up at 7/8000 hours they think it’s barely ran in.

Had a demo of a 6155r last weekend which had DD, couldn’t make my mind up if I liked the DD or not. Not sure if I’d go autoquad or autopowr. Local contractors first batch were no bother at all but last batch were troublesome

Got 2 x maxxum 145 active 8 gearboxes here. One just been split to have some work done. From new they lose drive. Time will tell if it fixes the fault or not but if it does the other one will be going in. Software is the biggest issue throwing codes for this that and the next thing. Turn it off and on and goes so long again

Were your 2 early ones as i know of one other 145 that had early softwere issues and i was told mine was one of the first new softwhere ones.

might’ve been yes. New on farm august 19. We’ve had maybe 4-5 software updates that were meant to fix these bugs or fixed everyone else’s apparently but either make it worse or no difference. Patience wearing thin tbh with case. Changed the front brakes at 2500hrs on both due to loader work and the gearbox type is what they blamed it on. Electric spools are another big bear but that’s a Cnh “thing”

These guys just take standard 1 year JD warranty.

Would have good guys in workshop though.

 

[balerman]

We have just had one go on our 6215 which is well out of warranty at 7000 hrs but JD paid 3/5ths of repair bill

Would still have been a big bill tho...

We have a vw Tiguan dsg really good positive drive compared to normal auto box but is expensive to Service oil &filter every 40k.had a nh t6175 DD on demo last year to compère with our JD 6145 DD .you can bye a nh DD with Reasonably low spec mechanical spool valves and no daft telly screen. I hate all the shite that goes with JD bloody complicated. Yeah bit off topic really but it’s my pet hate.

According to most of the forums the oil change every 40k is a must and unfortunately no fleet car with 100k on clock will of been done. My next one will have to be a DSG so will be looking for a 40-50k miles one. We don’t live in the best of places to tow and manouver trailer and caravan with a manual so conventional auto would of been perfect.

 

[ford 7810]

Yes the conventional type auto fluid toque converter? Will probably handle reversing shuttling type of work better than dsg type.haven’t got my head around the dsg stop/start clutch yet but got to be heavy Wear some where.

DCT's are not ideal for towing. Not for hill starts, which is their weak point. Actually mine has a fairly low first gear and a wet clutch so should, if all other things are equal, work as well as a pure manual gearbox without the possibility of burning the clutch out towing out of, for instance, Llangrannog while meeting several lots of holidaymakers on the way down. If you see what I mean. However, it has yet to be proven how robust these wet clutches are. At least on mine, the clutches [both of them] are fed with their own forced and cooled oil independent from the mechatronics and main gearbox.

On the flat it should be no worse than for a dry clutch manual gearbox and if the wet clutches are well designed, to last, maybe they are better. The stop-start on DCT transmissions, at least on my car, works seamlessly and smoothly. Couldn't tell the difference between it and a planetary unit with torque converter. However there's no significant wear when starting off heavily loaded uphill with a torque converter, so despite generally having a high ratio first and reverse, they work very well indeed with the TC basically multiplying torque at the wheels by being an effective variable ratio.

That’s my worry with them aswell. This Audi I have now is very easy to stall as it just switches off if revs drop under 750rpm to protect the clutch and driveline. It’s no good in a sticky situation on a hill with something heavy behind!

I had a gasket went in mine a few months ago. Out of warranty (4k hrs) I was fearing the worst and they changed bearings /circlips as well.
Only bill I had was for new oil.

 

[ford 7810]

It isn’t just a case of fitting heavier circlips the shafts or hubs need to be changed to except the thicker circlips

You must mean 'accept'? Unless you mean that the circlip is no longer fitted after the mod, which may well be a possibility.

Spelling mistake i do mean accept

Dig a little deeper and you'll probably find a lot of repair and maintenance is done to get them to those hours. They're also working longer hours, so more hot running doing the same thing over and over again etc. They also get to know which components fail and at what hours. They are then changed out at routine service instead of waiting for them to fail in work.
Tractors on the other hand could be on haulage one day, high draft work the next, then something requiring max power from the pto the next, which dictates a compromise in design. All with untrained drivers, limited servicing and a mindset of run it until it stops.

If something like a gearbox failed on a truck or construction machine it would be changed and put back to work without a thought. With tractors, they're more likely to be considered unreliable junk, that needs traded in as soon as possible.

 

[kiwi pom]

If you had a DD Deere with say 7000 hours that hadn't failed, but you knew it was in a run of potentially bad machines. Would you split it now and replace the offending parts, cross your fingers, ship it off or keep running it until it went bang?

Your mean like on 20 and most 30 series auto power vario 'boxes?

The plant boys have a right laugh at us with these tractors. It’s a joke hardly any warranty and they won’t even standby it half the time anyway. School boy hours and it’s knackered. No plant machine would be entertained with this performance. All made to a spec. The tractor manufacturers need to improve dramatically
