OK one thing that my tractor does is it seems to smoke ALOT!!
OK it it starts perfectly in the Cold (when the bateries are fresh). It has NO Blow by to speak of and when I bought it, I Dynos between 95 and 100 Horse Power. I already fixed the radiator leak with a new radiator. But where is all this smoke comeing form? The Oil Level is Black but not Low!! Where could all this smoke be coming from is this something to worry about?

Like I said the Oil is Black as can be. But, I was told that is very common for diesel engines. I am familure with car engines I know the oil should be a Honey Gold color, but did not know if this applied to diesels or not. Also for some strang reason the tractor came with a 14 quart M&W Oil Pan, but no Turbo....just more info to throw in here..

Most diesels turn the oil black almost instantly but not all. It's normal. I had a Hino truck with a rebuilt engine. It didn't use a drop of oil but when you started it, especially in winter it would choke you out. The smoke was so bad that if you were standing 50 ft. away you couldn't see the truck. After it warmed up, it had no smoke at all. Idling is bad for diesels. That's why semi drivers always turn the idle up when they're stopping for a rest. Otherwise they would start to smoke a lot and even start slobbering thick black liquid out the exhaust. Diesels need to be worked. Maybe that's all your tractor needs. Dave

not sure what year 4020 you have but from 68 on down they smoke worse than that of a 69 or above.Somebody told me deere changed piston styles and rings.But I have never seen a 4020 that didn't smoke a little. my 67 smokes a little a idle but clears up after I throttle it up. Unless you start using a fenominal amount of oil your probably ok

First thing since you just got the tractor is to change the oil/filter. Use quality oil Chevron Delo 15W40, Shell Rotella 15W40, Mobil Delvac 1300 15W40. If smoking presists, then the previous owner or the dealer to meet the dyno HP expectations may have turned the pump up a little to much. Don't know abou the JD4020, but I have a NH and the manual tells how to adjust it a little at a time, by observing the smoke, when accelerating the engine when fully warmed up. Check your Operator Manual or Repair Manual. Tom

Don't know what you call alot ? Some of these diesels smoke more than others too. I once had a JD 2840 that started smoking really bad after an overhaul,luckily it turned out to need a timing adjustment. Hard to say maybe yours could be improved with some adjustment ?

Yes it is my first diesel. I once heard a guy tell me that his problem was that his machine was no worked hard enough! He worked the MESS out of it for about three hours and it cleared up ALOT! He said it due to alot of oily fuel build up in the engine.....
Well the types of jobs I am going to do I don't think I will barley have the throtle open!! Maybe a quarter of the way..

A lot of owners manuals state to "avoid prolonged idling", work at 50% throttle or higher and use the gears to speed up or slow down. A lot of the older Case's I've had said not to run less than 1500 RPM in cold weather. I just kind of adopted it for everything.

Yes,

See the pictures I put up.

Putzin' a diesel around is the worst thing you can do for 'em. They were built to pull hard all day long.

I think you're gonna be okay tho. A lot of guys around here had those 4020s and used 'em as cultivating tractors. They don't smoke at moderate loads. Quit worrying, give 'er a chance; it's okay.

Raleigh,
They are just teasing you. During your tractor search you were very specific about what you wanted and very worried that there might be a flaw in what you bought. Nothing wrong with that but most people would have found something close and been satisfied. Differential lock is nice but most of us get by without it.

blue/white smoke is usually motor oil, diesel smoke is usually black...specially under a load. hard to say what you mean by grey smoke. does it smoke all the time or just under a load? diesels smoke...just their nature. i wonder what your compression is like.

i agree with the other guy...change your oil and filter. never hurts to KNOW your oil is good instead of just wondering about the color of it.

We had 4020s on the farm when I was still there, all of them had that light blue grayish colored smoke out of the exhaust while idling or just putzing around. It would clear right up as soon as you put the tractor into a load, and if the load became heavy enough, the smoke would turn black. I would say that you have absolutely nothing to worry about.

What's wrong with diff Lock? everyone I have talked to down here says the wished they had it. Is it something thats a troubled spot? I would think that it is the only other option being that these 4020 did not come with 4 wheel drive.

There is nothing wrong with a differential lock, it is a good thing, and even though it WAS an option, and most of the 4020s were ordered with that option, there were a few that never had it.

Is it just smoking when the engine is cold, warm or both? At idle or at higher engine speeds? Under load? Blue/gray/whitish smoke is usually fuel smoke - take a whiff of the smoke - if you can smell unburned fuel in it, that's what it is. Diesel engine oil usually gets black after there are some hours on it - how black and how soon depends on the condition of the engine and how it's ran. The black color is usually soot/unburned fuel, so a tractor that's not running correctly or that isn't worked hard enough to get warmed up and burn the fuel completely will blacken the oil sooner. Could be nozzles malfunctioning, pump timing, a pump problem, air filter restriction, etc.

Well all I have done was change the radiator and driven it around the yard and it pretty much somkes like the red one in Allens Picture. It seem to take a while to warm up a littel longer than a car.

I will go ahead and change the oil. The dealer said the oil SHOULD be fine because they fixed some syncronisers in the Transmision they had to split the tractor, that was back in the summer. Since then He used it to cut a pasture with a 15 foot batwing mower (what ever that is).

raliegh...diesels never get as warm as a gas engine. if it's real cold out, throw some cardboard or a tarp in front of the radiator for a while.

a batwing mower is like your bush-hogs, only with side wings that raise up and down. allen will probably tell you they come with an optional differential lock on them.

I have not figured out what is so Bad about haveing Diff Locking. They are there if you get into stuck ground and need help in getting out. I had a 5020 for about 6 months and I got it stuck in a muddy low place and had a to truck get me out. Then my owners manuel came in and It explaind what that funny littel pedal was under the seat!!! Had I known maybe I could have saved my self a head ache and 100 bucks!!

Yup that's about the only time a differential lock is valuable--when your stuck. You have a chance to get out, or else busted.
That smoke is normal. I have an 1855 Oliver that has that fuel smoke all the time. Put under a light load it disappears, get a real good load, like say a 13 foot disc and a 15 foot rolling harrow in soft ground and that smoke is BLACK. Shoot a 12 foot Great Plains drill will load her up good.
By the way the 1855 and the 4020 were competitors.

A differential lock is good and handy during normal field work. As was posted, it helps keep the tractor in a straight line and can reduce the tendency of an implement to pull the tractor sideways. Also helps a bunch on sidehills. And improves the efficiency of the tractor by keeping the slippage constant between both rear wheels. As for helping when you're stuck, nine times out of ten a differential lock will get you deeper, not out.

I used the differential lock on my 4020 a lot. When planting, it helps it go straight. When plowing it helps it go straight and get more work done from not spinning a tire. When disking it helps it go straight and without the differential locked it hops from side to side and that ripped off one muffler when it got violent. Now with differential lock on, it just hops up and down, not side to side. That's disking in plowed ground at 6 mph the first pass.

The entire differential lock except for the little pedal is inside the housing and all run by oil pressure so there's very little to rust from lack of use. Maybe the links from the brake pedals that turn differential lock off.

But I've gone notill, I don't plow or disk and I plant with a smaller tractor to save fuel. The 4020 is the loader and tall sprayer tractor now.
