What’s it worth , classic JD?

[Robt]

So we have a JD 7700 power shift .
it’s a year 1993 with approx 8000 hours. Very tidy just needs two new tyres.
what’s it worth £16k?

 

[daveydiesel1]

If was powerquad would be worth 20k+ but powershit will hurt it badly. Id say less than 16

I was looking for a new tractor for my tmr-mixer a few month ago. I found a nice clean 7700 powershift with 4500 hours. I thought i was good priced at about £22k. My mechanic said “don’t buy it - better find a power quad with 10.000 hours”. Those are ridiculously priced, so i got a different tractor.
I don’t know the market over there, but 7000 series powershifts are very cheap here.

 

[Farma Parma]

am no JD man nor expert but you can keep ya clunky pquad all day over them lovely full powershifts in there day.
Id be asking a JD Specialist but surely its still worth a bit more than that ?

I have never owned a power quad and hopefully never will. They may be reliable, but from an operators point of view, i really don’t rate them compared to other brands. But i was adviced agains the powershifts because of possible high running costs.

The 8.1L engine in the early 7/8000 series is the most reliable agricultural engine built. You’d be surprised at what they turn up in (trains, boats, plant, generators) they weren’t plagued with the same head gasket issues as the 6.8 and 4.5L engines. I’m not saying they never brake down but for the volume produced they beat any other on the market at the time. It’s only after they went to common rail and the 9L problems crept in.

one of my neighbours had a 7600 that was pquad but it had the 4 shifts & direction change on the same lever & that was quite neat to use.
lovely comfy tractor to operate.
Once had a go in a 6900 standard pQuad & all that clutching to go up the gears...
clutch was like a lead hammer also. Shifts was jerky, it was no spring chicken & well worn id say.
The neighbours 7600 was a far better tractor.
Plenty who know will tell you the american built ones them 7600/7700 etc are the better ones by miles.

Waterloo built rather than Mannheim?

Yeah wasnt meanin the larger ones was talkin smaller 1s like 6 series. If could get powrquad and sisu 6 cylinder infront would be sum yoke

Originally yes, the tractors and engines where built in Waterloo, if I remember right though the newer 9L engines for the EU market are now built at the Saran factory as well as Waterloo.

We had a power shift 7800 new in 93/94. Did 10,500 hours no problem.
Used to get the gearbox re calibrated every now and then. Great tractor.

 

[Phil P]

To be fair the original 7000 series power shift wasn’t a bad bus, the shift wasn’t amazing (give me a 4955 any day ?) however it was a pretty reliable transmission.
The problems started when the 7010 series went to a digital fema valve and shift, as a-pose to the analog on the 7000. The 10 series where renowned for been a barsteward to calibrate and the shifting was horrible! It was a running joke at the dealer that the power shift came with a free neck brace ?

If you come across a 6010 power shift run away as fast as you can?

Wasn’t it a 7.6 ltr engine in the 00 series and the 8.1 was only fitted later to the 10 series.

Yes, our 7800 had the 7.6.

Funny isn’t it, we had a power shift 6910 from new to just over 10’000 hours. It was a good tractor, I don’t remember any gearbox issues, it got a bit jerky towards the end.

Only in the 7600 and the 8100, think the 7700 was the 8.1 but I could be wrong.

 

[76masseyman]

7.6. Went to 8.1 in the 10 series 7000’s.
