Subject: late 7000 vs 7020 differences

OK I am looking at two different tractors.  One is a 7000 Black Belly (1979 I believe) and the other is a 7020 (1978  possibly 79)    both tractors are similar, they have cab and rubber is about the same on both.  They both need a little TLC but are repairable and thus priced likewise. 

What are the main differences between the 2?  any one significantly better that the other? 

They both have the same 649T engine only the 7020 has an intercooler thus a little more HP correct?? 

What about transmissions?  Do both tractors have a wet clutch? Not 100% sure yet but the 7020 has a power director transmission.  based on the year I am guessing the 16 forward and 4 reverse...but not sure yet.   I hear a lot of people say the powershift transmission is better..  
Which brings the question....What exactly is the difference between a power Director and a Power Shift?  How do they differ in operation? 

Any other major differences to be aware of between the two?  rear gears? Hydraulics? 

all other things equal,  at similar prices, is one significantly better than the other for any reason.

7000 in my mind is a glorified utility tractor. Open center hydraulics, small frame ect. 7020 has closed center hydraulics channel frame, power director or power shift. Both good trannys but for longevity I’d go with the power director. Just my thoughts

20 speed PD has;
5 gear trans x
2 shift Range (Slow/Fast) x
2 Foot floor buttons(Low/High).

16 speed PD has;
4 gear trans x
2 shift Range (Slow/Fast) x
2 foot floor buttons(Low/High).

12 speed PS has;
6 gear trans x
2 shift range (Slow/Fast).

Both PD require foot clutch to be disengaged to shift both Trans & Range. Floor foot buttons are “on-the-go” shifting(no clutch). Floor buttons are usable in every gear/range, so extremely convenient for slower headland(turnrows) maneuvering. 16 speed was standard. 20 speed was optional.

PS’s trans gears 1-6 can be shifted “on-the-go”(no clutch). 2 speed range shift requires foot clutch disengaged. Operators right hand can quickly move 6 gear trans lever between desired speeds.

Heres a photo of each trans console. PD is on the left. PS is on the right.
Both trans have a Range shift lever on their right sides (Park-Slow/Fast).
PD's T-handle can twist&To-Fro for selecting 1,2,4 forward, 5,3,R rearward.
PS's lever moves forward 1-3, then 4-6 & moves back for R.
All the 7010,7020,7030,7040,7045,7050,7060,7080 models have Rear-end Differential Lock as standard equipment. Don't think the 7000 offered it?

isnt the 7000 basically a 190/200 with a 3 speed pd?  or is that just the maroon belly?

Thank you AC7060IL!!!!   that is exactly the info I was looking for on the transmissions.  It seems online everyone uses Power Director and Power Shift interchangeably so I have never been 100% sure which was which.   Seen where many people refer to the foot buttons as the power shift button....

As for the one I am looking at.  He says it has a PD but I'm not sure which one.  Waiting on pics.  

I am kinda leaning towards the 7020 right now.

What is the advantage of the Closed Hydraulics?   I see looking at specs that the 7020 is rated at double the gpm as the 7000.  Other than the flow, what are the other differences? 

Just from looking at the pictures, I see the 7020 does not appear to have the hydraulic pump mounted to the engine in the same place as the 7000.

7020's hydraulic pump is positioned in lower front of transmission & on tractor's right side behind auxiliary fuel tank. There may or may not be a transmission protective plate (under belly plate) covering hydraulic pump/front of transmission. It was standard equipment, so plate should be there? Trans/drivetrain drives hydraulic pump, not engine.

That was the maroon belly.  The black belly 7000 was more similar to its bigger brothers.

The black chassis 7000 got the new Acousta cab 2 like the bigger tractors did. The black chassis got the gear shift moved from the floor to the side console as a "TEE" handle shifter like the 7010's and up. The Power Shift clutch was changed slightly internally to use "low" range as the inching clutch, instead of the dry clutch on the flywheel. Other than that, it is the same tractor as the maroon chassis models. Nothing in the drive line is shared with 7010's and bigger. The bloodline came from the 190/200 and while the rear end housing and 3-point hitch look very much the same, I can assure you not one part in the transmission or final drives is the same as a 190/200. The differential and brakes are similar, but that is it. The torque tube is a completely different casting and different internals from a 190/200. A fully independent 540/1000 PTO was standard equipment on the 7000 tractor.

The difference between a 7000 and a 7010/20 is about like the difference between a WD45 and a D17 lmao! Entirely different drivetrain family.

Given the choice, go with the 7020.

Yea After doing some research I am definitely leaning this way.   Just dealing with some logistical issues with picking it up.

The 7020 has power brakes.

And massive wet clutch, differential lock, planetary final drives, much heavier 3 point, far better hydraulic system and bigger rear end components. Plus, more common parts with the other models.

7010+ is a vastly superior tractor to a 7000. From a marketing perspective I think that Allis even making the 7000 hurt them. Hard to have one sitting on the lot and be claiming "all new improved design" and then have a lot cruiser walk around the "same ol (you know what) in a new dress" that was the 7000. yes, 3 speed, live PTO, etc. so it was improved from the 190/200, but I would have been alot happier with it if they just called it the 205 and made it a sister machine to the 185 and didnt let it wear the updated bodywork.

Updated body should have been exclusive to the updated drivetrain of the 7010+

So, in closing, buy the 7020 and pass on the 7000. if 7020 sells before you get to it, start looking for a 2-105 White. Id personally avoid the 7000.
