"Tractor is big enough to do anything I want. And can get you in trouble too if you don't watch yourself on it. Be safe Always."
"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."
"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."
"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."
"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."
"Bought used with 33 hours. Tractor has performed well so far. I would recommend this machine. 90 hours."
"Nice tractor."
"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."
"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."
"Good tractor for my situation. Dealer very good about addressing any problems. e hydro is a plus for snow removal and bucket use."
