I'd like to buy a 100 hp (or so) Allis before spring. I'd love another 190XT (should never have sold mine) or a 200 but I'm worried about getting a gear jumper.
Are there any concerns/known problems with the 3 speed powershift on the 7000? I'm guessing it's similar to the Oliver & White Over/Under with an over-direct-under? I'm wondering why it wasn't used in more models? Or was it? Thanks, George

Unlike the Oliver and White models, it won't free wheel going down hill in low on the power shift.

Personally, I never liked the model 7000 tractor when I was selling/servicing them. For another couple thousand bucks you could have had a real tractor (7040) with hydraulic clutch, power brakes, closed center hydraulics and a differential lock. They would have been better off to have the 7010 (with an intercooler) at 110 HP, the 7030 at 130 HP and the 7050 at 155 HP when the new family was introduced. Put the 7000 chassis at 100 HP with a little brother at 80 to 85 HP. That way, the 7000 driveline would have been used in two models ( small one with 34 inch rears and 7000 with 38's) to spread out production/engineering costs. As far as the 3-speed power shift driveline in a 7000, it was quite trouble-free. Far better than the 190XT and 200 it replaced and it had a 540/1000 PTO standard equipment that was truly independent !!

The black 7000 (wet clutch on the foot clutch) when equipped with the HD front end was a great hay baling tractor. Shifting has to be learned and trans brake adjusted correctly . We had almost 0 failures out of 30 + units we sold. (if you don't count the failures due to customers not knowing the hyd system is a separate compartment like the 200 etc and seizing the brgs due to no/low oil)

I rebuilt my powershift due to leaky seals, but it never left me stranded. I believe the tractor sat for some length of time somewhere in its life, because almost every seal has been replaced in it that wasn't submurged in oil, but not the tractor's fault. The black belly 7000 has a wet inching clutch, so you always start out in 1st range. The plates are thicker to take the additional load, but they are not available through AGCO anymore. That being said, it is basically a power director with an overdrive set of gears in the bell housing ahead of the transmission. The tractor is a little old in technology, but it is also quite a bit lighter for its HP rating than its bigger brothers, so that was nice for hay and pasture maintenance - less compaction and less weight to lug around.
