4120

Hydraulics have been a problem-bought tractor new after 2 hours steering would stop working & 400cx loader would chatter - took 2 years for dealer find bad steering valve now has hydraulic wine worse in cold weather dealer states normal condition then 1 year later steering cut in and out, out of warranty I called JD & would not help not happy hope to trade soon.

Pros: grate tractor when hyds. work
Cons: to much money for tractor with part time hyds.

Glad I Did It
Model Year: 2007

Looked at ALL the tractors before I bought this one (including the Tytans). Very glad I went with the Deere. It is so well put together. Everything fits, everything works the way it should. The quick disconnect FEL (the whole thing) is a feature I never would have imagined using, but it is so nice to be able to set it aside EASILY when doing 'detail' work in the yard such as fertilizing or plugging. I grew up with normal clutch shifting tractors and thought the hydro was a waste. I am also glad I went with the hydro. My tractor is easier to drive than a car. My young kids are proficient driving it. I know it sounds funny, but she is stored inside and gets a bath every once in a while. About 6 years old now and everyone thinks she is new. I have a wood chipper, blade, brush hog, a 3-pt bucket, and a proper set of forks. I use them all regularly. I can't say enough how much I love this tractor. Deere is soooooo worth the extra money.

Pros: Solid, dependable, put together well, strong.
Cons: The beer holder sucks.

John Deere 4100
Model Year: 1999

I like this tractor very much. It has 4 wheel drive which is very useful on mountain hillsides. It has sufficient power to handle a 42" bushog mower and a 4' finishing mower. My only criticism is that the operators platform is too cramped for an arthritic old man (78 years). Getting on and off is difficult for me. On the left side the transmission lever is in the way. On the right side the control for the front bucket (which I don't have) interferes with getting on and off. The sway chains on the three point hitch don't have a way to lock the adjusters allowing the lift arms to collide with the rear tires unless you adjust them frequently.

Pros: It is a great little tractor except for the cramped operators platform.
Cons: Lift arms frequently getting into the rear tires.

Living in the north east, I can say I wish this had a block heater. Would not start on several cold days. Had to bring in heater to warm the storage container that it is housed in. Also wish it had more lifting power and the bucket has creeped down ever since it was new. The John Deere dealer said they all do that. I am not sure about that. It has been reliable and it is a perfect size for most homeowners with a little land. LOVE the 4x4 capabilities and it has bailed me out many times.

Pros: See text.
Cons: See text.

JD 4120

Bought used with 33 hours. Tractor has performed well so far. I would recommend this machine. 90 hours.

Pros: Has more than enough power and turbo assist, if needed.
Cons: Does not come with a rear hydraulic.

Nice tractor.

Pros: Very nice tractor and very well thought out.
Cons: None.

Deere 4120 Hydro w/Loaded Ag Tires for Clearing Wooded Lot
Model Year: 2009

Spent considerable time looking over the current 3 and 4000 series Deere machines. Thought I could manage with a 3520, maybe a 3720 to get adequate HP to drive a chipper. Other concerns were overall weight (more is better) and wheelbase for stability in angled wooded terrain. Ag tires for soft muddy soils were preferred and they are have not disappointing, however, they will chew up lawns. Wanted hydro for frequent loader/grapple type activity. Found a 2009 4120 with 200 hours. Came with loaded Ag tires, ehydro, deluxe seat, box blade, MX6 bush hog, 400x loader, rototiller, forks. Had concerns about the 400x series lift capacity, but that concern is long forgotten. Overall, this machine is perfect for my needs. Since getting it, I've added a 448 backhoe, Wallenstein BX42 chipper, Farmi 351P winch, Frontier AV62 grapple. The only thing that does limit me is the front tires sinking into the mud when in soft clay or sandy soil. I've used the differential lock and front bucket to get me out of a few muddy situations. Had to wait for things to dry up. Overall, LOVE the 4120. Has plenty of power for my needs. I'm not a commercial guy, but even if I was, I would not be disappointed. Used to think the 4120 was huge. After running it for awhile, it feels just about right. Now the 3520 looks small. Keep in mind we're clearing 2 acres of mature oak and maple. I've got a guy with a full size excavator working hard to move some of the biggest stumps. I added a 3rd valve, with oil line extensions, and a power beyond kit myself without much suffering. Also mounted the rock shaft adapter plates myself. My dealer is okay, but won't budge a nickel on price for anything. After spending a thousand dollars on hydraulic kits he did give a 1 tie wrap for free, which is the ONLY thing I've gotten. When I bought my grapple for $2000 he wouldn't even give me a free hat. All Deere dealers here in Maine seem to work from the same playbook. But I do love the tractor. I bought Deere because the dealer is 3 miles from my house. I'm not partial to any particular brand, but prefer not driving more than necessary. Buying used has saved me a ton of money. Feel fortunate. As often mentioned on this site, bigger is always better when getting into a rip/tear scenario.

Pros: Reliable, ample wheelbase, weight and power.
Cons: Dealers are standing by to empty your pockets and bank account.

4120 with 400 x Loader eHydro
Model Year: 2007

Got it with R4 tires for general landscaping and I also make 18 acres of grass hay. Machine carries my 7 foot disc mower with ease as well as my 328 square baler. I also use a 50 inch tiller and the eHydro is perfect for creeping with the tiller engaged. Loader is excellent and does all kinds of work (can do about anything your mind comes up with). I highly recommend this machine for my 50 acres, many gardens, snow removal, and of course--mowing.

Pros: eHydro with 4WD.
Cons: Price.

JD 4120
Model Year: 0

Good tractor for my situation. Dealer very good about addressing any problems. e hydro is a plus for snow removal and bucket use.

Pros: Quality, dealer attention to problems.
Cons: Draft links seem to limit attachments use.

Great Tractor
Model Year: 2006

Great tractor - FEL, forks, bucket, box blade, finish mower and backhoe. Used a lot to landscape new yard and work in rock hard clay / mud. About the only complaint was that initial (new) dealer installed the backhoe with the wrong quick disconnect hyd. fittings so I could not reconnect the hoses when I first took the backhoe off the tractor - second dealer in new location fixed the problem but it cost several dollars for pickup / drop off and labor. Lots of power for any of my equipment. Quick change on forks and bucket is especially useful.

Pros: Power, ease of handling, 4 wheel drive.
Cons: None in first 350 hours!

John Deere 4120
Model Year: 2007

I bought this tractor practically brand new with 120 hours on it. I store it inside and take very good care of it. It has the 400cx FEL. I am very pleased with everything about it. I welded hooks on the bucket ends which makes hooking things with chain VERY easy. I also welded a 2" hitch receiver onto the top of the bucket which comes in really handy. I have a Goosen chipper, Woods bush hog and a really cool back blade. This Deere has not let me down except for the time I burried it deeper than the axles in mud. I guess I can't really blame the tractor. I built a custom box for the ROPS that includes a radio. I love it.

Pros: Everything.
Cons: Nothing.

4120
Model Year: 2011

Traded a 2003 JD 4310 for the 4120. My property is one large hill so the power and stability of the 4120 is really appreciated. So far, very pleased with the tractor. The 4310 was also a great tractor.

Pros: Great tractor.
Cons: None.

4120 Tractor
Model Year: 2011

After extensive research, test drives, long term resale. The choice was to go with this model.Has JD motor, turbo, very nice operator platform, controls well laid out, fit and finish are very good. The 400cx loader is what stood out for me. Very well built, easy to maintain and grease. All sorts of attachments available. Dealer network is close buy for service. You do pay more for JD but the long term payback should be there when you go to sell the product, if you look after it. I have seen good used tractors sell for next to new price after being in service for 5-10 years.

Pros: Watching your friends envy you driving your new tractor.
Cons: Having run out of work for your tractor!

John Deere 4120
Model Year: 2011

This tractor has a lot of power for its size as well as a lot of lift for its size. Generally I am satisfied with the ease of operating as well as what I can do with this tractor. The turning radius is very tight which makes it easy in maneuvering in tight places. I found out today that the differential lock only works for the rear differential and not the front. I am very disappointed about this.

Pros: A good tractor overall, easy to operate, plenty of power.
Cons: Differential lock doesn't work for front differential just the rear.

Awesome Compact Tractor
Model Year: 2011

This tractor has all of the power and lift capacity that a small land owner could need or want. It has exceeded my expectations by light years. It is so easy to operate that a small child could do it.With my other small tractor, I did more work operating it than the tractor did. I would definite buy this same tractor again.

Pros: Plenty of power for it's size.
Cons: It needs to be a thousand pounds heavier.

John Deere 4120
Model Year: 2005

I purchased this tractor from a JD dealer in Michigan who sold it new to the county to maintain its baseball fields. The county traded for a new JD this spring & I purchased it via "Machinefinder" on the first day it was listed. So far, I have primarily used it to mow using a 72" Kingcutter finish mower. I have cut chest high weeds in 95F temperature and high humidity conditions and it performs flawlessly. There was no overheating as sometimes reported by others for this model. I have a very steep hill on the property that I mow downhill with the front axle engaged and the rear differential locked. I literally hang by the seat belt as the tractor creeps down. The only problem I have had was accidentally disengaging the front axle with my hip when I hit a bump. Slid down the hill (R4's & very dry, hard ground) without the front axle holding me back. Used the FEL as a Flintstone brake. Used the 400 FEL a couple of other times moving rocks/construction debris and knocking down a pile of topsoil. I was surprised at how strong the loader is, and how precise the controls are.

Pros: Excellent power.
Cons: Lever to engage the front axle should be moved away from the seat.

Great little tractor
Model Year: 2006

I bought this tractor for light chores around the house and yard. Boy was I surprised to find out this "little" tractor was much more than I expected. The size is deceiving. It has much more muscle than bulk, meaning weighting is very important to both performance and safety. The power of this machine can easily overcome the weight. Anyone considering a CUT will be pleased by this tractor. I also highly recommend the E-Hydro trans.

Pros: Lots of power
Cons: Needs more weight

JD 4120 review
Model Year: 2005

Good solid tractor with great comfort and ease of use. A little concerned about long term reliability,support, and cost of keeping running over the decades like my deeres of the past.

Pros: Parts and dealer support
Cons: "fly by wire"

fantastic tractor
Model Year: 2008

I got a bit larger than I really needed and am very happy for it. Plenty of power, runs great. American made. I expect many years out of this one. I totally baby it... it lives in a heated shop. The fit and finish is fantastic. It is smooth. Nothin' really does run like a Deere. I would never get anything else.

Pros: perfect machine
Cons: little rubber markers on the hydraulics get caught in the brush and are gone
