Default John Deere Power Shifts 8960 and 8970 Any good?

Hey hey all!

Been shopping around for JD 8960 and 8970s for a grain cart tractor and am just curious if anyone has had any experiences with these tractors...good or bad? In particular with the powershift? was it reliable? How about the cummins engine? anything good or bad to report? Thanks in advance for your feedback!!

get the 8970, the cummins in that unit has the stc injection system, they smoke less and run a little nicer, 8960 just as good. I have lots of experience with cummins motors, they a cheap to repair, do a bearing roll if it has more than 5000hrs and a valve and injector reset.

never seen a 60 or 70 series with a powershift, they are all 12/24 speeds around here. very good tractor though

Drove a 8960 with powershift and i really liked it,like all other tractors from that time period with powershift(Case 91xx,92xx,Versatile etc) they shift a little rough,but at least you can change speeds on the go and keep your tractor rolling.Those 60 and 70 series have a twin disc powershift,used by Big Bud,Buhler-Ford-New Holland-Versatile,Massey Ferguson,ACO and many other brands,its a good old school powershift gearbox.

CIH used the Twin Disk Japanese clone, Fujitec(SP?).
It had a button on the gear shift lever that if pushed and the lever pushed to faster gears shifted 1>3>6>8 (I think) quite rapidly.
All other powershifts of the day in 4WD's were 1>2>3>4>5>6>7>8.
Been 15 years since I drove a 9280, but I think that's right.

I spent a fair bit of time in the cab of a 9380 and they do indeede have a button you can hold down which will make it skip gears. Can't remember the sequence though, i never used to use it.
