john deere 420

Got my hands on a JD420 yesterday. The rear PTO hardware and wire was removed earlier including the panel switch and light on the control panel. As best I can see, there is a loose black wire, blue wire and a male three prong laying free. Any ideas of the open electrical scenario I have...

I have a 1989 JD420 (Onan P220G-20hp), a long time ago, i was told they switched from a points type ignition to a solid state ignition somewhere between the late 80`s and early 90`s. My problem is, i have no idea when the point vs solid state thing happened, but i want to replace the ignition...

Has anyone changed out the Onan engine for the Honda Replacement? Were you satisfied with the swap in terms of performance? Thanks!!!

The generator isn't charging the battery, it could be a broken or loose wire. Or it could be the generator. Is there a simple way to check to see if the generator is charging? I am eclectically challenged, so please keep it simple. Bill

Hi all, I have a John Deere 855 tractor with a 420 FEL. One of the lift cylinders has developed a leak. I tried replacing the seals but no success. There are a few youTubes on this which are helpful but lack detail. Can anyone point me to a shop manual, or other reference, that covers this...

Hey all, Going to change out the Hydraulic and Transmission fluid shortly and figure I would maybe try and rebuild the bucket cylinders. The bucket tends to drop as soon as it has a load it in, or not, but faster with load. It is the bucket's curl that drops, not the lift. However, I dont...

I have a 420 loader with serial number 9759 with a bucket cylinder that is leaking through the small hole in the side of the cylinder - see attached picture. Based on the parts diagram, it looks like this hole is where the Tie Band/Wire lock is inserted, but this is my first cylinder rebuild...

Hi, new to TBN. Just bought an 88 JD 420 for $600. It won't start, no spark. checked everything down to the ignition control module.

Picked up a project last week. Lower mount for transmission that attaches to crossmember broke off the housing. Tore tractor down, got it welded up, repaired a few items and just about done reassembly. Hoping someone can help me out and solve this mystery.

Intermittent failure to turn over, now gotten worse and wont even turn over now. Battery fully charged - Dash Lights On - New (kit) Starter Relay - Bypassed Seat Switch & Hydro Switch on the lever. Turn the ignition on, go to start, nothing. Can hear the timer box, cycling sounds the same as...

So yesterday I did some mowing, and pulling a wagon up the hill with some firewood, and on the last task & firewood trip I turned the key and just heard the starter motor whirring away, but not engaged whatsoever. It's a new battery, and the machine was running just fine moments before. I left...

I have no spark. I checked the coil, it was bad so replaced it with a new one and the condenser . Coil wires, plugs are good. Does not have points. She is the P220G model Any suggestions?

Hi all.... After brush hogging with my JD 420, I went to park it and had no clutch...period. The pedal feels totally disconnected...no resistance. If it's the connecting linkage, will this require splitting the tractor to reconnect? Any suggestions appreciated. John

I am selling a 1956 JD 420 with bicycle front end that was restored approximately 5 years ago and used no more than 10 hours since then. I would characterize it as "parade- and field-ready." Any idea what a reasonable asking price might be in South Carolina?

Recently purchased a 855 JD with a 420 loader attached. Question: Does the loader have a latch lever on both sides? Thanks.

My 420 loader bucket cutting edge is 3/4" thick. For the width that I need, 59 1/2", all of the toothbars that I see are manufactured for a bucket with a cutting edge no more than 5/8" thick so the toothbar would not fully engage the front of the bucket. Does anybody use one of these on thier...

The battery light comes on after I mow for 20 or 30 minutes. The second I disengage the PTO the light goes off. If I keep mowing with the light on it eventually blows the 20amp fuse located behind the instrement panel and the engine dies. When I replace the fuse the engine will start again...

I installed factory rubber isolator rear body mounts on my john deere 420 garden tractor. This lifted the body up about 1" and subsequently lifted the gas tank filler neck up and now the gas tank is not being supported by the frame. Now all the weight of the gas tank is resting on the filler...

Any interest in a article how to relocate hydraulic pump from midships mount to rear for the 44 loader/33 Tiller? I've done it and while it takes some fabrication and machine work it's a worthwhile investment in time.

I dont know if this is normal for the 420's but I have to keep holding the speed lever up when pulling. If I let go of the lever the tractor will slow down. This happens in higher gear and not so much in low.

I'm in the process of restoring my first tractor which I picked up in rough shape. I've fixed most of the issues and have these remaining ones. - The hydro pump started leaking badly. Can I fix it without removing from the tractor? - Where does this stray wire go? Thanks!!

I'm trying to start the engine while finishing up my jd 420 restoration. The engine ran on the gas in the carb, but once that was used up it died out. I had replaced all the fuel line, filter, cleaned the tank out and put new gas in. There is no fuel being pumped to the engine and the fuel...

There are two types of throttle cables listed in the jd parts catalog but they dont differentiate between them. I have an 84 model 420. Do I need to get AM125290 or AM39536. They are listed as 3A and 3B in the parts diagram. Also there are two choke cables listed as 9A and 9B.

My 1984 JD 420 is missing the tail pipe from the muffler. Looking at replacement mufflers I notice the pipe coming out through the body is straight, however, the way my muffler sits it looks like a straight pipe would run directly into the body panel. Were there different mufflers for the...

I just got my first tractor a 1984 JD 420 and in the process of restoring it so I have lots of questions to come!

I'm attempting to replace all the short hoses on my JD 420 loader. Last week I busted a cylinder rod and I ordered some aftermarket bucket cylinders from surplus center. They come with SAE 8 (1/2"?) female fittings which I understand is fairly standard for a lot of cylinders. Anyway, since I...

My tractor runs fine at low and mid throttle. But if put it up to full throttle, it wants to die. If pull choke out half way, it runs fine again. I've used carb cleaner ' spray ' in the past when I've had similar problems , and it works for a while , but , the problem always seems to come back...

IM replacing the yoke on the transmission end of my driveshaft. The u joint " cross " is not bad. Should I replace both anyway since I have it off and working on it ? Or, don't fix what ain't broke? Sent from my iPhone using TractorByNet

Anyone know where to get a trans shaft cheaper than JDParts.com ? They want $550. the yoke from the drive shaft has worn the teeth on the trans shaft. And the drive shaft then in turn wobbles, Which in turn vibrates the whole tractor. Any suggestions? I originally thought it was the u joints but...

Ok. I've learned how your supposed to go about changing the u joints on the drive shaft. Now, I'm trying to figure out how to get the driveshaft out. I took the four bolts out where it's connected to the engine, but it still won't budge. Is it just froze and needs banged around a little bit, or...

Knew guy to TBN. So after a lot of research on jd garden tractors I settled on a older model 420. They seem to built like a little tank versus the newer ones. After looking for a nice one for awhile finally found one close to home in nice condition and for what I was willing to pay. Only down...

Just purchased a 420 w/the B48g engine. It is running like it is too rich. I cannot find the "fuel " screw on the carb, just the air mixture screw I believe. I've read elsewhere people with the same problem have adjusted the points and it solves the prob. Here are my symptoms-idles just fine...

OK, my 420 loader on Deere 4400 would not stay up. Not just not stay up, it would drop six inches in two minutes.
