I have looked at a JD 4030 that is for sale. It will not go into roadgear and is a little hard to shift into a few others. Seller said a mechanic friend told him something about clutch needed some adjustment or something. For you experts, does this sound more like the clutch may need replacing or could some of the gears be getting bad? Do you know about what it would cost to have a clutch replaced at a dealership? Also, this tractor is on gas instead of diesel, any thoughts there?

Sounds like the linkage needs adjusted and lubed. Its not too bad if you have a service manual. But to make sure, take it to your local JD dealer and see what he thinks,it usually dont cost nothing for them just to look at it. As far as beeing a gas burner, keep good clean fuel in it as the carb is the most expensive part. When you get time, install electronic ignition on your tractor. Otherwise, they are really easy to work on.

I hope this will help you. I have an early 4030 tractor with wide front and soundguard cab. It has a quad range tranny. The quad was optional and the sycro was standard on these models. You could not get a powershift on the 4030. The engines were 6 cyl. 329 diesels and 329 gas. (Same engine). I have only seen one 329 gas engine in a 4030 with a wide front so far. I heard they use the 329's in some of the combines but I don't know how well they are on the fuel situation. I also think any 80 hp gas might be a little thirsty, but maybe someone else can comment on that. My diesel seems to be pretty darn economical though compared to other engines of that horsepower. Mine was dynoed at 90 hp. A great tractor for what I use it for. Also it has a perma clutch. I believe if you had the syncro tranny, you had the regular clutch. Check your linkages, also if it's really cold out, give it a little time to go into gear. Just my $.02. Leon in Mn.

Just where in Minnesota is this dealer with a gas 4030 for $3500? Since there were only 222 gas tractors made, they are about the same scarcity as a G High Crop!! That sounds like someone should pounce on it really quick

Want a relatively rare JD? Well, a 4030 Gas is one of them---only 222 built, and only in 1973. As for the tranny problem, sounds like a linkage problem to me---since it's either a Quad Range or Syncro-Range (Power Shift was not available on 4030 tractors), most likely the problem is in the linkage or the quadrant. Hard shifting can also be caused by worn or damaged detents as well.

Charles--I have a 4630 that had the same problem. Check the shift cables from the gear shift to the trans. Mine had dried up from use and made it very diff. to shift, go to park or any gear. Also mine was a power shift. Asuming quad is the same. Hopes this helps. Bill

Quadrange has direct rods going to the transmission,and they are easy to adjust. I'll bet this early model has a synchro range, like the new generation tractors. Everything we farm with is diesel. Depends on what you use it for.

What kind of transmission does it have?? As for the gas engine, collectors are starting to gobble the gassers up quite fast. :-)

Only 222 gassers! Engine parts have to be rare and expensive if found. Narrow-front on the 30 series seems to be very rare as well.I bet I could pick up a 4030 pretty cheap if it is a NF.
When tractors are 80 h.p.+ or so and gas, the fuel consumption rate just skyrockets. I have a Case 930 gas(80 hp) but I don't farm to many acres so it's not so bad. I picked up cheap $2,500 in good shape because it was gas.

Engine parts, no problem!! The 4030 used the 303 gasoline engine, also used in 55, 95, 6600 combines, and other Deere self-propelled machinery. Sure wouldn't let that one stop anybody from buying a rare tractor.

Mr Strange,

I believe there was a 329 JD gaser involved in the lineup also. A neighbor had one in his 6600 combine that he recently purchased. I heard about and had to see it. I think there was a switch in the combines on engines, not sure on the 4030. I'll have to dig and repost. I agree on rarity. Parts shouldn't be a problem.
The transmission bugs me. My tractors turned real loose(too easy) when wore(4020,4230 etc). The 4030 may have a dry clutch,(non perma-clutch) and the shifting would be trouble, like a tired 4020 clutch. Permaclutch tractors (4230,4430) have never bothered. With many hours on both, other components needed attention before the clutch. Anyway, 4030 sounds like a neat project. I'll check on 329's.
Bill
