    JD4120 Error code 67 and Where does the other end of the purple wire go?

    I would think it would be really easy to find the other cut end to reconnect, but no..... And, is the sender being disconnected the reason for the "67" error code on the display? [/URL][/img]

    How to clean *A LOT* of vegetation of a split rail fence?

    Need to clean off about 10-11 years growth, I was going to use a chain saw and cut it all close to the ground, but that seems like it will lead to 10 stems for each one that is there now. Thought about spraying it with some sort of vegetation killer (not sure what?), and that would take...

    How to adjust rear pto clutch 4120

    I tried searching... ""adjust pto clutch 4120" brought back 1700+ results in just the JD owning operating forum, went through 5 pages and couldn't find what I'm looking for. My LX6 mower blades stop in high grass. My pto shaft cover is loose, so I can see it's the PTO shaft that stops turning...

    PTO driven Salt Spreader

    I have a plow for my JD 4120 which works okay, but my driveway is steep. The plow seems to leave enough "fuzz" that once it gets packed down, the tractor can't drive back up the driveway. I've found plenty of 12V salt spreaders for the back of pick up trucks, but it seems like it would be a...

    4120 engine injection pump spring update

    Dealer just took my 4120 in for an engine injection pump spring update. Anyone else have this done? Any ideas what it was supposed to do? My tractor, since it has been new, would change engine pitch, and start to put out some additional smoke. It does it intermittently. I figured it was an...

    Grapple  4n1 vs Grapple vs grapple arm on existing bucket..

    I've read lots of good posts on Grapples and on 4n1's. The attachements I think I really need to take car of my 10 acres of woods with leftover construction clearing debris for use on a Deere 4120 w/400x loader are: 1) A dedicated HD grapple (clean up the pile of stumps, some fairly large) 2)...

    4120 smokes...

    My 4120, which has 111 hours on, developed a problem. I'm not sure exactly when, but it has been doing it for a while. It is an intermittant problem where the exhaust gets real smokey, it looks like oil smoke on a gas engine. When i check the crankcase, the engine oil level is fine, so i...

    Wow, the cab looks nice...

    I was just over at Deere's site. The Twenty series cab looks nice. I have a 4120, I guess if i want a nice quiet climate controlled cab, I'd need to sell it and get a 4320? Darn, doesn't seem to be in the budget...

    FEL Problem

    My FEL (400X) on a 4120 has developed some strange symptoms. Bucket does not power down. It floats down even when the lever is in the power down postition. As soon as the bucket makes contact with the ground, it stops, it won't lift the front of the tractor, or put any pressure in excess of the...

    Speeco QH, what else do I need?

    I have a 4120. Right now, I really only need to remove and replace an LX6 so i can hook up my manure spreader. I guess I may want to hook up my ballast box as well. I was going to go with the iMatch QH, except non can be had locally since all the nearby dealers are out of stock. The speeco...

    Buyers remorse, did I buy too much tractor?

    On May 2nd I ordered a 4120/X400 loader/LX6 mower. it won't be in for a few weeks so I can probably change my order. I used a friends 4310, which i understand is now discontinued, with a 300x loader, It seemed like all the tractor I'd really need. I need to primarily mow about 7 acres...

    W,hat Tractor do I need?

    I just found this site, I've been looking for a tractor, leaning towards a JD, but having trouble deciding on which one. I was hoping to come to a conclusion on which one before the current incentives expire on 5/2. I have 18 total acres, with a new house and 6 stall barn. The land is about 10...
