Now that’s harvesting corn in style

[@ColinFisher]

The non-pivoting unload auger on the 6600 was a pain. You had to be vigilant for power poles and other objects. My grandpa came within a whisker of wiping out his fuel tanks when he forgot about that thing sticking out. Thanks for the video, BTP!

[@brandonthomas1298]

Great combine. We run a 6600 on our farm with a 444 4row corn head

[@ryanhbell]

Brandon Thomas Same, but we run a Turbo 6620

[@sevans1178]

Quite impressive machine. 6620 was a great combine and still is. looks like that farmer's crops are just as good as the other video I recently saw the X9 harvesting. I wonder who has to send the biggest portion of their crop to the creditors?

[@paulaoki5474]

I spent hundreds of hours in a 6600....memories!

[@carlosalbertoorozcorizo4479]

In the 90's my uncle had the complete "collection" of the titán series... 6620, 7720 and 8820, so I learned driving in the three machines🤩🤩

[@bigtractorpower]

Very cool line up.

[@kennethcarlton2860]

Great video . I started running a 7720 yellow top model then went to a 9400 , then a 9500 & finally a 9500 with a 9600 engine [ at least that's what I was told ] had to retire in 2003 & wasn't running the combine but was hauling the grain from them . Again a Great video Thank you it brings back memories for me

[@brettengland192]

We used a 6620 along with a 4400 back in the 70s, 80s and 90s. The 6620 was an enormous improvement over the 4400. It had a much more comfortable cab. I also loved the hydrostatic drive transmission. We harvested wheat, corn and soybeans in southwest Missouri.

[@bigtractorpower]

The 4400 is a solid combine but the Titan SoundGard cab and additional power was a big step up.

[@keithdickson8364]

We had a 4420 on the farm I worked at. Spent many hours in it. Great machines.

[@mikekf0eap16]

got a new 6620 with pusher in 1985, quite an improvement over my old JD 55 mud was so bad that harvest we didn't even try to get the 55 out.

[@allenmoore4186]

The combine I learned to harvest corn 🌽 with! Classic combine.

[@bigtractorpower]

👍👍

[@ih1206]

We run a 79 model 6620, she’s set up to cut soybeans right now. It replaced the old 4400 and man is it light years ahead of that machine. The biggest feature is the feederhouse reverser. Spent many days with a spud bar and a pair of pliers trying to unplug the 4400, it had a nasty habit of plugging the cylinder. The 6620, ive yet to plug it so bad that the reverser couldn’t unplug it. Great machine!

[@bigtractorpower]

The 6620 is a solid machine. Revers made a huge difference. I just filmed a 4400 in corn Sunday afternoon.

[@ScottPykare]

Back in the day we had 2 7720's. Really good combines. They were top of the line then. Still see some around. Mostly on smaller farms. Love the video Jason👍👍GO BTP!!💪

[@jeffb321]

Our neighbor still runs a 7720 titan II. I bet they will out last the x9s

[@danmichaelis3222]

6620 is still a good combine, I've owned mine for 25 years and still going strong with only 3000 hrs . It's a 1983 model sidehill

[@herringtonfarms6816]

What’s top speed on hwy. I’ve found one I’m thinking about driving home vs hauling it.

[@tf7274]

Nice to see a 6620 with a proper set of rear tires. Ours were like the front tires of a 4440...

[@Bishopaaronbeachy]

Lol my grandpas is the same way

[@jtoddjb]

I've been considering a 6600 combine near me for sale. comes with both corn and grain heads for $5000. It's seen better days of course but runs and functions. Now I just need good land

[@garywest8901]

Thanks B T P. I run a 4420 on our small farm in southeast Ky. Enjoy seeing the old stuff and appreciate people that keep them going.

[@lukedesselle4589]

I've got a 7720 and it's still a really good solid combine

[@Flyanb]

I wonder if he wishes if he had some of the automation? Is he glad he doesn’t? All I know is he can still fix his own machine!

[@bigtractorpower]

The farmer seemed very happy with his 6620.

[@kirklothert3435]

Classic John Deere combine

[@lfeco]

They were a big combine when they came out. Local dealer has a 6620 on his lot parked next to a 790. It sure looks small compared to that one. You're right BTP, combines have come a long way. I just wonder what they will look like in another 15-20 years.

[@bigtractorpower]

That is a good question. They will be much more automated.

[@jennycraig99]

Looking forward to seeing your 9500 in corn. A farm I film in KY went from a 4420 to a 9500 this year. Big jump.

[@mikep7810]

@@bigtractorpower That sounds familiar! It certainly was a huge jump when we did oats

[@chrisfoulk4715]

We use a 6620 on our farm. Have model 215 grain head and a 643 corn head. Basically the 6600 and the 6620 are the same combine except for the engine,cab, grain tank and auger. JD did make the walkers wider so it wouldn't plug up so easy. There's nothing worse than having to crawl into the walkers and unplug them.

[@BIILLETT]

I remember the first 8820 I saw in a field and I was like “Look how huge that machine is!!” Now these are small fries compared to today’s stuff.

[@bigtractorpower]

The 8820 was a monster in its day. The 8820 was 225 bu. Just less than half of this Lexion.

[@larryd8224]

I believe John Deere had the traverse mounted single main cylinder of the original self-propelled combines and then at some point changed to a longitudinal twin rotor separator design. IH changed their SP combines to the longitudinal Axial Flow design about 1969 and stuck with it after they became Case IH. AGCO Gleaner retains a traverse full-width main cylinder in their Natural Flow design.

My father-in-law had 2 6600’s. Good machines but they were worn out when he passed. Have since sold them both. I miss the corn and soybeans.

[@bigtractorpower]

The 6600 was s good combine.

[@bubbawubba2307]

Bet that was a tight squeeze getting into that cab. after spending thousands of hours in the 6600-8820 II series I can say the 8820 walks off and leaves that 6620 or even the 7720 in the dust. Things I didn't like about any of those combines. Dusty, Hot, awkward cab not in center of combine, poor clean grain elevator design, corn leaves and bean dust clog the radiator up every day and other things. What do you like? You can work on them, not many sensors to worry about unless its the radiator getting hot and it starts buzzing. Low cost.

[@chadjustice8560]

Of course it would lol the 8820 was a monster in it's day

[@SilverGleaner]

I like all old combines but I love the L2 Gleaner over the 20 series Deere. Better cab, better layout of the controls, and easier....much easier to work on. The Gleaner conventionals needed a reverser and an easier way to adjust cylinder clearance (though once set I never found the need to change until I switched crops) with those two items the L2/M2 would have been the perfect machines.

[@Blackwellll3066]

Really cool combines im just surprised they aint using a 500 bu grain cart cuz stopping to unload everytime the combine is full got to be slow harvest

Does it really matter?

I need a combine. I don't know why. It does it all right there in the machine. That's a lot of horsepower for those that think their car has that much or more.

[@seth1704]

We have 2, 6600 id combines. 1 has the 100hp 329 diesel, the other 128 hp 404 naturally-aspirated diesel. We have a 6620 turbo also with the hydro. It burns more fuel but it sure is more fun to drive, it has a lot more creature comforts and will not slug nearly as fast.

[@LackoFarms]

We have a 7720 Turbo, one of the last series of serial numbers before the Titan II

[@SimonKL11]

A great classic combine😁👍 Well done😉👍

[@Diesel.09]

that 6620 is 4wd too

[@markreetz1001]

Those were some fine combines. Were the snouts on cornheads longer back then than they are today, or is the size of today's combines making them look shorter? Just a thought. Thanks for the video.

[@mfreund15448]

Hauled a ton of corn from that model of combine in a barge box wagon.

Very cool. A barge wagon is something I hope film some day with a combine.

my cousin got out of farming this year and they ran a turbo 6620 yellow top but didnt have lug tires on the rear just reg tires had around 5000 hrs on it

[@johnmessinajr.2591]

What was the first series of John Deere combines to have a reversible thrashing system? We had a John Deere 105 combine and it was not reversible if it got clogged.

[@bigtractorpower]

I would guess the mid model Titan Turbo Models like this 6620. I would guess around 1982/1983.

The 6620 was one walker narrower, had less horse power and smaller grain bin.

Hi Sar Bhai

[@noelhohberger1188]

Still see alot of them around

[@SilverGleaner]

They are pretty much all gone in my area.... I know of one part time farmer with a 6600 or could be a 6620. There are a few old Gleaners around yet and some old 1400 series IH rotaries. A couple of brothers that lived across the road from each other each had near perfect 6620s until a couple years ago they sold them. They retired some years back (in their 80's now) so they were just sitting in the sheds. They each brought $5000 which was high because they were both low houred and pretty. Usually I see them sell for $1000 or less unless scrap is high. Most new machines are green in my area where Gleaner used to reign until the dealers disappeared.

[@miguelangelvalderrama1808]

That combine needs new green paint, with that color looks old🤔🤔 and needs some flood LED lights too.

[@jojodancer4947]

It seems that the manufacturers make a model of combine or tractor for only a few years, is that one reason they are so expensive? Do they make enough spare parts so the farmers can keep using them for a long time or are they forced to buy new every few years do to lack of spare parts?

[@chadjustice8560]

Usually models of almost everything are made for over 10 years so they don't change every few years. I can't speak for every company but to this day through Deere anything from 1923 to 2020 you can go to your local dealer and get parts. Some combines they have stopped making parts for but not many.

[@casetheprotogen1167]

[@matthewtaliaferro4902]

Why is it running slow?

[@bigtractorpower]

That is speed these combines ran 40 years ago. Combines have come a long way.

[@shortytari]

While this is mostly true the other factor involved is yield. These machines are 35 yrs old. When they were new 200bu corn was exceptional. Today it’s expected and from what I have seen on videos 250 plus is common. These machines just don’t have the thrashing and separating capacity to drive any faster in that big of a crop.

[@Bishopaaronbeachy]

We have one of these and we normally run ours in corn at about 3-3.5 mph. Seems to handle it fine

[@SilverGleaner]

@@Bishopaaronbeachy In 200 bushel 18% or less corn my L2 with 6 x 30 head can do about 4.5 mph on flat ground but at 22% moisture it gets slowed down a bit because the corn doesn't flow as nice. Speed is affected greatly by moisture and yield and terrain. My L2 will flow corn out the back at even 3.5 mph in wet 250 bu/acre corn which I've done..... thankfully the visual tailings return to my right immediately shows corn flow by your window to let you know. Something I miss having on my R52 so I have to make sure the grain loss monitors works in that. I know Gleaners best so an M2 with 6 x 30 head in the same conditions...... 18%, flat ground, 200bu/acre will do slighty over 3.5 mph. An M2 is pretty much the same capacity as a 6620 in most crops except wheat where an M2 will slowly crawl away from a 6620. Anyhow your 3-3.5 mph with acceptable loss at near ideal conditions would be about right. Not sure about the conditions in the above video but my neighbor would crawl at 1 mph with his M2 and later his 1660 in 185 bushel dry corn because he wanted no field loss.......... but he is an excavator by trade and not a farmer. The 1660 taught him that a fuller machine is more efficient and now does about 3 mph. Still too slow in my book.
