Combines a bit off subject AC8070

If FWA it is worth $5-7k more. Make sure the engine is kept within rpm specs. Both the PD and PS trannies are bullet proof. The bearings and universals in the FWA need to be snug or they get pricey fast. The plug in the planetaries of the FWA should be opened once a year to relieve pressure build-up from temperature changes. I own an 8030PS and an 8050PS FWA and love both of them. I personally don't think the new Agco's have surpassed the AC 8000's. Also the AMBAC Fuel system is known to have drooling noozles with age and caused the 8030's OH when I bought it, scored the wall of the sleeve.

We have had an 8050 and an 8070 which was front wheel assist they are good tractors but have a short wheel base on the front wheel assist models. i like you loved the spacious cab my favorite part being the wide fenders. Just curious is what year is the tractor and does it have front wheel assistIJ If it does does it have the big tires or the smaller ones. Good tractors and the powershift is nice.

The 8070 was ahead of its time. Nice big cab, good lighting, easy service and short turning radius. I would take a PD over a PS if you are going to do any heavy tillage only because you have so many more speed choices. The PS would be nice for a cart or planting tractor. The motor is generally regarded as the weak link. Many motor failures are indeed due to a faulty fuel pump. Running regualar oil analysis should detect fuel in the oil preventing wash out. Speaking of oil, it should be changed 100-125 hours under heavy use . You could extend that to 150 for light use. Rear end, axles and driveline components are very solid. Hub duals are a bonus as is FWA. A low houred(less than 3,000 hours) FWA would easily be worth $20,000 in Il. I have seen very good ones bring $25,000 or more. 2WD is a different story. Easily discout that price $5-7K.

we had a 7050 years ago. was a good tractor, but we just plain wore it out, bought a 1486 IH, mistake there. we would be using this tractor as our big one, we also have milk cows, so we would be chopping with it, i think the PD would be the way to go. you say the lighing is good, ive never ran a tractor with lights on the top of the cab before, is there much glareIJ i do live the big fenders and cab. shes a fwd, is it a elect, switch, or like in the agcos (9170) where you have to pull a deal out.

they were talking about this on the red power site just recently. i believe dealers wanted the motor thats in the n-7 in the higher hp. tractors but i think allis wouldn't consider, what a combination there could have been. instead we've got a 3 main motor that cannot handle the higher horsepower capabilites. maybe up until recently but the hydraulic system on the 7-8000 series stink. as far as running hyd. motors and using the hyd. levers, forget it. no way to put a power beyond on these animals. rebuilt my 8050 a few years ago and should have put the cummins in it for 3-4 k more. more hp and better fuel useage. would have paid for the extra cost with just the fuel savings alone. any dealers know the real skinny on thisIJ

It's an electric switch between the shift levers and hydraulic levers. The FWA can not or should not be used on any road surface unless covered with snow or ice.

I would disagree with you about the hydraulics. That was and still is a state of the art system. It doesn't have the gallonage that we have on today's tractors. I run hydraulic motors with my 8030 virtually everyday it is running and have way less troubles with it than running on green tractors of the same era. Don't need the power beyond as everything can be run through the outlets and if you think you really need power beyond, it can be done. I had heard a similiar story on the N7 motor. Duetz Allis's biggest mistake was dropping the 8000 series and dropping that powershift which would have easily taken them into the 90's. Kelly

You are correct on the hydraulics. The same system is used on most of todays tractors; in only some cases is the usable flow greater. Anyone having trouble using the system should do the research on how to utilize the system as to hyd motors and such.

John is right about the FWA switch. As far as lighting we have never had any glare problems. All we added was a long range light on the front weights to see down the field farther. We still have a 7050. Went through it a few years back. Makes a nice auger tractor for a 12" auger. My biggest dissapointment with the 8000 series is they are cumbersome in row crops if you want to cultivate, plant or sideress. As our operation grew we went from using our 8070 as second tillage tractor to wanting to plant. We spent $$$ on taller narrow tires and it still was cumbersome. We still use it on our mower, grain cart and drill, but we do any row crop activities with our 8870 New Holland.

We had an 8010 with fwa. If you are going to be chopping with your 8000, you'd prefer the powershift. It's easier to up and downshift a wider range of speeds as windrow conditions change - also while turning on headlands. The other posts are right on the money - the 8000 series were way ahead of their time. The red and green guys can argue all they want as to who was first with the wide cabs, wasp-waist, etc, but WE know it was Allis Chalmers who was the real pioneer. Good luck- Tom langan
