Adding 100HP to JD Combine

ke8wo · Mar 23, 2019

This may well not be new to many here .. but it was to me. Here is a YouTube video showing the steps to crank up the HP of a JD combine to 100 more HP. Its certainly not clear what JD thinks of this: my guess: not much!

Why does a combine require 100 more HP ?

the tractor vet · Mar 23, 2019

It's like this , sure you can add more pony power to the engine BUT will the rest of the machine take the added power with out self destructing . tweaking a couple more ponys might not be to much but add in a 100 sooner or later something is going to say enough is enough and go KABOOM , then when that happens at a most in convent time while you trying to get the crop in ahead of weather and pushing hard you have done shot yourself in the foot , it's not the machines fault . Ya want more power get a larger machine . Or get two machines to cover your acres . I have never met a farmer that has ever said his piece of equipment had to much power , it's always can ya get me just a little more.

The newer John Deere combines are of rotary threshing,they do take more power, my neighbor also got a Cat,that's the cylinder machine, that Cat burns 4-5 less gallons per hour,and they go round for round and has a 5 foot bigger header on soybeans ! When u unload on the go,with the Deere you get extra horsepower, and as soon as you shut off the auger it drop down again.I agree with the vet, don't do it. The John's belts and gear boxes, are already maxed out!

Some combines are designed to increase
power when the unloading auger is
activated.

Because the residue is touching the rotor for a longer time,than with a cylinder machine, it's bing bang boom, it threw there,now it's on the rattle chain or in beaters, well on it's way to the chopper! If it's dry it goes threw pretty good,but if damp, it takes power!

In the video, they were changing to a much larger corn header and hence the desire to boost the HP. I believe they ended with a boost of something like 25, 50 and 100 HP .. each one selectable from the JD's operator's panel.

There have been times when I wished I had a bigger bin. Many times I wished I had more elevator capacity. More cleaning capacity would always be nice. The only time I recall running out of power was trying to keep a machine full, and fighting mud at the same time. I try to avoid that.

It is the same with most big diesels these days. They are built to offer power over a pretty wide range with little more than computer programing to reset. When I had my truck with C-15 Cat they offered me 50 more ponies. I asked about fuel mileage and they said only 1-2 less. I said no thanks and kept it at 475 with 6.5 MPG.

My Gleaner Fs were about 91hp werent they, add 100 hp and man you could make a lot of corn spit out the back end as you flew through the field.

Get in hills, in mud, in a good crop, in a wet fall wet crop, add a bigger header, unload on the go, if you add enough of these issues eventually you want a little more hp
to keep up.

The epa is sure trying to clamp down on these modifications to Diesel engines, they don?t like people changing the pollution control requirements. I think it will be harder
and harder to find anyone that will get this done as time goes by.

Starting to see corn heads that cop the stalks and
leave a nice shredded residue. Chopping all of
those corn stalks, while separating the corn, takes a
lot of power

Bob Bancroft · Mar 23, 2019

Especially since GMO corn. Those stalks are like little trees!

Even before chopping corn heads, I figured the corn head was doing most of the work of combining corn. There's a lot going on there. Running just ears through the machine is easier than a small grain with all the straw.

A neighbor friend who does a lot of custom work has had header drive issues even without a chopping corn head. I could wonder of the manufacturers are going to beef up their drives, as many of these exotic corn heads are aftermarket.

We cranked up a 2388 CIH once. The governor was lazy but we turned up the fuel first with poor results because the governor just wasn’t opening it up so we figured out how to liven up the governor. It takes a long 4 mm Allen wrench if I remember right. Then we put it together without turning th fuel back down. I was running it and got into some tough barley. The rotor belt started slipping but the engine wasn’t pulling down. After replacing the smoked out rotor belt it dawned on me it had more power than it needed plus some more so we cranked it back down. It had so much power with it cranked up I just had no feel for how much of a load the combine had on it.
