IH transmissions

i am looking at either a 966 986 1066 or 1086 IH tractor with cab a/c and heat radio and so on. do these tractors have powershift trannys or are they standard? i see lots of pictures of the inside of the cabs and see two shifter handles on the left side of the seat are they for transmission of others like i have said before we are deere fans but are going to be switching to red before spring planting season and would like some honest information about these machines

The one lever is for Park, High, Low and Reverse.

The other lever is for the four gears in each of the High,Low and Reverse.

No it is not a power shift and none where offered in those models.

The TA (torque amplifier) is like a power shift in each of the gears but only two speeds in each of the 8 gears.

So if you are in High 1, you would go about 6.5 MPH with the TA ahead and about 5.0 with the TA back. So TA does give you one power down shift to get you though a tough spot.

I'm being forgetful tonite.

You do NOT need to use the clutch to move the TA so it is like a 2 speed power shift in each gear.

Gary he is pulling your leg if they are green they arent going to go Red for planting. A farmer who plants with green would surely know the points about the Red tractors..

You would think so Gene but there may be some that have never been in a red tractor.

Maybe he is young and just getting started gene.

i have not been in a red tractor but once or twice and i was little our family had one about 20 years ago and had problems and got rid of it, it was there only red tractor all our stuff is green combine, grinder all 4 tractors, loaders, manure spreader auger wagons baler rake swather and disk mower rotary motors power washer (its yellow) but still deere, lawn mowers all of my kids toys, both planters, old rusted out 2 bangers in the fence row choppers i dont need to go on and yes i am young and trying to keep up and keep our family farm going and deere just seems to expensive for my pocket book (for instance got one in the shop for a small transmission problem ended up going to cost $6400) thats the reason for the red switch and i may even go brand new but thinking of going to a older one for now. i'm not gripping just letting you know i am serious

I grew up on a multi-brand farm and still farm that way. I get to know the parts guys at every implement shop that way.

travz500, if your green planter is a vacuum operated JD, the 966+1066 are completely out of the question along with most 9+1086's. You can't run the hydraulic motor for the vacuum pump with the hydraulic pumps in those models. You'll burn up the pump in the tractor ($$$$$) before you're done this spring. In fact you would have to get a very late model 9 or 1086 (a 1981, the last year) with flow control hydraulics to run a planter like that. If its a finger pickup JD planter, any of those tractors are fine. We have a 1066 and it is my favorite tractor. For the most part the 86 series have nicer, quieter cabs with a/c, but I think the 66's ride better.

I have been running a sprayer with a hydraulic motor to power the sprayer pump for 5 years, with a 79 1086 and have not had any problems yet.

The same tractor runs a loader the rest of the year.

It runs over about 1500 acres a year.

You can run hydraulic motors with old IH tractors. I should have been more specific. The speed of the motor on the vacuum pump controls the vacuum pressure on the planter which affects the quality of seed placement and varies slightly on seed size. This speed is regulated by reducing the flow going to the motor from the tractor. We run hydraulic motors with our old IH's as well, this is not the same. The blower on the planter would probably fly apart if ran at the flow rate coming straight out of the tractor, but if you rigged something up to reduce the flow, then you would burn up the pump in the tractor.

The 66 series are a bit easier to work on because of the cab setup. Everything on an 86 is underneath it. To pull the cab on a 66 you just unbolt it and lift, on an 86 ALL the controls are mounted to it. And it's easier to see the drawbar on a 66.
Also the TA is not meant to be downshifted to slow a speeding tractor. It's built to be shifted under load. And you'll lug the IH a bit more than any deere I've been around. Pull the TA around 1400-1500 RPM on a hill for best results, much higher and it will slow the tractor then start pulling again. And DO NOT stop the tractor by throwing it in park unless you have an emergency. They have a pawl that engages a gear in the reverse gearset and there's a good chance you'll bust something if you do.
The 06, 26, 56, 66 series all had a lever below the wheel that engaged park, with H/L/R and 1-4 on two levers on the right side of the dash. With the 86 series they put park on the same lever as H/L/R and put both levers on the left side of the seat. With the 88 series they were put on the right side of the seat, and the hi and low TA were added into the gear lever(at least on some models).
The 86 series has a quieter cab and they hold more fuel.
If you get an 86 series without the full cab you WILL get a very thick coating of dust on your back after running it in dry conditions all day. With the windshield and no back window the dust rolls up around from under the tractor and coats everything. That's my biggest complaint about them. After a day hauling silage with the 786 my hair was more dirt than hair. You can pull the windshield but would have to make a new exhaust brace mount as without one it doesn't take much of a branch to take the top out of the underhood muffler.
