Hi. What years were the 8820 T2s made and I hear reference to the "green top" model being the latest and also the greatest of the 8820s. Can you share any experiences with the T2s as far as model year changes and how much better they performed after each "upgrade"? What year(s) were the green tops made?

The T2's started in 1985 and went until 1988. I can't really say if they were changed much during that run but if you go from a T1 (yellow cab) to a T2 the T2 has a two speed cylinder which is much heavier than the T1's were. This helps alot of soybeans mainly. Other than that I can't think of anything else. Our T2 had plenty of capacity, we used to run a 930 header in 40-60+ soybeans and it always kept up. One thing that some guys did was but a solid cylinder conversion (don't know who made them) and that was supposed to increase the capacity considerably.

There is really nothing wrong with the T1's though, the neighbors used three of them on around 10,000 acres up until around 2003 or so when the 50 series was out.

I am sure someone older than me could tell you more.

The Titan11 started in 1985 and is the green top. As far as I remember, the Titan11's had longer walkers. The shoe is also about 6" longer and was sped up a bit. The clean grain auger is different. Some say the paint is better quality on Titan11...not sure.

Parts catalog does not indicate when a new design concave rod retainer
must be used when installing new 13 bar concave on new generation or
titan combines with pin (- 600000).

Solution:
When installing new 13-bar concave on titans with pin (-600000) also
install corresponding new concave rod retainer as listed in the chart
below.

When installing new 13 bar concave in new generation combines and
using the original finger bar do not order new concave rod retainer.

When installing new 13 bar concave in new generation combines and the
adjustable beater grate or finger bar, also install corresponding new
concave rod retainer as listed in chart below.

According to the brochures, the walker length stayed the same, 150". The chaffer length did increase 6" to 66.7" on the greentop TII. the other major difference was the horsepower got bumped to 225 from 200.

Don't be afraid of the earlier titans. Our 82 8820 was 220hp, and my neighbours 84 has a 2 speed cylinder, he is the original owner. Both these machines I speek of have around 6000hrs. I also have a titan 2 and don't see much difference in capacity. Don't let hours scare you, if the combine has been maintained really well, it will run for ever. There is not a part on these combines I can't get in 24hrs.

1979, 1980 machines are 8rw, lack of clean grain elev. capacity, same as 7720, also notice the lack of bubble on the right side clean grain shield. On these same machines they had a small inline injection pump, similar to 4640, and rated 200h.p., in 1981 machines recieved larger injection pump, like 8440,4840, h.p. went to 225 where it stayed through 1988.1981 machines are the first to be 12 rw ready, sorry red fans, deere was ahead along way back then,they also had the bubble on the right side elev. shield for the larger clean grain elev.1982 brought small changes, a adjustable rear h-duty axle, prior years run a fixed h-duty axle, however with the age of the machines some have been converted to 82 and newer stlye,and last about 1982 machines they had the small access door in lower unload sump, not the p.i.p that closed the larger hole on prior year machines. 1983, brought dual range cyl . drive, 1984 brought longer tail board to straw chopper, longer hoses on feederhouse for reel drive reel lift, due to different hoses on 200 series heads.Last thing about 1984, alot of people don't realize that the cleaning shoe is longer like t-2, food for thought,also 1984 machines have the larger fuel fill neck , not the red plastic covered one.1985 brought the t-2 , green cab, new stlye green tach., longer shoe , officially recognized, longer unload tube option, hardened chrome raspbars standard equipment.Also all t-2 gto a faster cleaning shoe, however most have been slowed down to 84 and older.Last thing,forgot 1983 brought harvestrak loss monitor from the factory. just alittle 20 series history. deerefever.

We ran a 1988 Titan11 for 5 years, and in them 5 years I only had 1 breakdown that took me 1/2 hour to repair (key in top sprocket of return auger got loose and fell out.). Best combine I ever owned or ran after that one in regards to breakdowns.
