I am starting to look for a tractor to build into a 3000 rpm open farm tractor. My question is has anyone ever changed the gears in a quad to get what they want? With the deere I have a few options, 4010 plant. add 10%, or 4440 two speed or is it easy to just change the gears to what is needed? Anybody done this, what does it cost, where can I get them? I want to stay with the quad range. Thanks

The turbo and pump you can run will determine what to do with your trans and final drive setup. So what are the rules for you?

This would be out of the box 3lm turbo, 466 cubes, 10 mil a pump, 3000 rpm, no water injection. Great Plains rules

you wont need to speed it up any. run d3-d4 with that pump and turbo it wont run good enouph for any faster gearing.

Buy one already built that runs good and save yourself a headache.

I can get gears made for you if you're interested

Can you make a 7 1/2 for a 4020?

Yes we can make 7 1/2 for 4020

With that setup you will be lucky to run c3-c4 on 20.8x38's. That is a decently strong gear so you shouldn't have much trouble with the drivetrain at that power level. A stock 3lm isn't going to make the power to be running d3-d4 unless the tracks are loose and you weigh less than 8000lb.

I don't know how to say it other than you should come watch this class pull. They are making some good power and running very tall gears from what it looks. I would think they wouldn't put slower gears in, but the gears they are running (slots) are road gear. I guess part of my question was to get a split gear between c3,c4 and d3/d4. I know some of the open farm pullers watch pull off, so maybe they can put some input in here, or tell me I am full of it.

Not Putting you or Great Plains pullers down, but if they are running road gear in that class, then sled is too light. If you think I'm full of it, then come pull at Jefferson next summer and you will see what I mean. Best tractors in Iowa in that class 12-16, none in Road Gear!

I agree with you. It would take 800-900 hp to run road gear here , and you still might snuff at the end.

HP - is there a way I can contact you about making gears?

does any one know how to or if a jd 2 speed can be built stronger like they do for an ih?

If your not running over 750 HP, they don't need to be beefed up. Just turn your pressure up. Some are running 1000 HP without doing any thing.

Re: speeding up deere quad January 04, 2012 02:51PM
i beleive them holding a 1000 hp is veeeerrryyyyy far fetched! and i bleed green and love john deere tractors. to answer ur question, yes they can be beefed up like an ih. i have mine beefed up to 6 discs on the high side and 5 on the low side. done all the machine work myself. not hard at all. all it involves is the machining of the 2 aluminum pistons. my stock one slipped at 400 hp, and thats no lie. and dont go jacking the pressure sky hi like yanmarr boy said to do, cause you will end up blowing your filter housing of the tranny case or shoving your crankshaft out the front of your engine as turning up the pressure also increases the pressure on your throwout bearings thus pushing harder on the crank in the forward postion. hope this helps a little.

I myself am moving up to the 3000rpm class that is very similar to the great plains rules and I am planning on running D3 and D4 in the 8700 class I been running C3 and C4 in the 11700 farm class so figured it would work being lighter and with more horsepower.

Re: speeding up deere quad January 09, 2012 03:33AM
OK builder, I will clarify my last post a little more for you. I did not say to jack the pressure sky high. I said turn the pressure up. Set at 205 lds. and put a higher grade bolt in the filter housing. Know of many guys running this set up with no problems. If yours slipped a 400 HP, maybe your should check your pressure. Not trying to be a know it all, just saying what works for us.

AM NOT TO SURE ABOUT THE HP 650 TO 750?? RUN ROAD GEAR IN A 10,250# CLASS. THE PRESSURE IS AROUND 220#. IT HAS BEEN 4 YEARS AND THE 2 SPEED IS JUNK. I THINK WE SHOULD JUST ADD MORE DISCS. THE WET CLUTCH IS A 5 DISC. CAN IT BE ANY STRONGER OR IS THAT THE MAX?? THE LAST THING IS CAN I CHANGE ANY GEARS TO GO FASTER THAN ROAD BUT STILL KEEP THE CURRENT ROAD GEAR??

If you have 750 HP at 10,250 lbs and can run road gear, your are doing well in my book. A 40 series quad is an over drive. A 30 series quad is an under drive. Can you spin out in road gear?

Re: speeding up deere quad January 15, 2012 03:30PM
There is enough room to get 6 disks in a 4430 wet clutch. The 2 speed can be beefed up as well by adding more disks. The pistons have to be machined and or replaced in it in order to do this. I have built several of them and currently have been reliaby holding 900-1000hp.

Re: speeding up deere quad January 16, 2012 10:16PM
Where do you remove matarial to add a sixth disk? Pto side or motor side?

Re: speeding up deere quad January 17, 2012 03:50PM
Motor side. 4 in front and 2 in back. In order to do that you have to spline your hubs when you weld the pto and engine hubs together that way the disk doesn't fall off the splines between the hubs.

Re: speeding up deere quad January 17, 2012 11:26PM
what do you mean by "your hubs when you weld them together?" im confused, i thought they were already splined internally and externally? i know about welding them together, but im not sure what you mean about splining them?
Reply Quote

Re: speeding up deere quad January 18, 2012 02:31PM
Your hubs are splined internal for the shafts, and external for your clutches. You have to weld the hubs together in a manner so that when you slide a clutch over your welded together hubs it can freely slide from one end to the other on the extrnal splines. This means you have to fill the gap between the two hubs and grind or machine the splines back out. Otherwise a disk can get caught between your two welded up hubs.

Re: speeding up deere quad January 19, 2012 01:33PM
that makes compltete sense to me now. thank u for the explanation. one more question, what part do you have to machine to fit the 6th disc and floater in?

Re: speeding up deere quad January 20, 2012 01:30AM
Both the front plate and the plate between the flywheel and clutch cover must be machined to fit 4 disks in the traction section.

Re: speeding up deere quad January 20, 2012 01:59PM
Will the front plate bend if it is machined that much

Re: speeding up deere quad January 21, 2012 01:23AM
No it still ends up nearly a half inch thick.
