4320 vs 3720????

[15acre&mule]

I'm shopping for my first tractor. I have 15 acres and plan to clear adn keep up all 15 one day. I got a 1000' driveway also. I have been looking at the 4320 but after my dealer telling me some that thier 4000 series can't stay out of the shop I'm concerned and wanting to know some more information on the 3720. How does it handle a 6' brush hog, How does it compare to the kubota L3940? What kind of price am i looking at for a 3720, 300CX, and a cab?

I've had my 4520 for over a year now and am quite pleased with it. I use it to tend our 22 acre place: hay mowing/raking/baling, brush hogging, woods clearing, that sorta thing. Certainly no reliability issues yet (only have a couple hundred hours on it though).

Feel free to send me a message if you have any questions on my experiences the 4x20 series. I'm afraid I've never used a 3x20 before, but I'm sure it's a good machine as well.

Have 4520. No issues that haven't been addressed. Yacked at dealer service manager, they have not seen any more 4x20 than any other mod.

I like the bigger engine, frame. It is noiser than the yanmar engine, but it also out performs it.

I looked at both these series and decided that bigger was better for my needs. I got a 4720 and love it. I'd go with the larger frame size for mowing. It'll be a more stable and comfortable ride. It's amazing how much more productive you'll be with the hydro.

The only time the 4720 went back to the dealer was to redo the back wheels so they were set wider (as ordered but not done at dealer so they did not even get it off the truck). All the 4x20 have the same engine just tuned and turboed different. No complaints (other than some of the ergonomics when changing fluids and such) and oodles of power.

Cabs are very nice once inside but a little tight for those of us with limited mobility.

I've had my 4520 almost three years and use it for brushing with the MX6, and loader work moving dirt and snow. have never had any problems. Great machine.

I have an open station 3320 and it is a great machine. I have an MX 6 mower I have for another tractor but occasionally use it on the 3320. The 3320 will handle a heavy duty chopper mower but I have to stay out of the bigger stuff (over a foot tall). The 3320 would handle a 5 foot lighter mower a lot better. The 3720 has a few more horses than the 3320 but would be the same weight. The MX 6 is well over a 1000 pounds and I have to keep the loader on for front weight. If I had the option, and could afford it, I would go with the 4xxx series tractor with cab. I priced both when I bought mine but the 4520 with cab was $12,000 higher than my open station 3320 E-hydro. That was too far out of my budget.

well price is definitly a determining factor for me as well. Now that i'm **** bent on a cab and loader, Price will be up there around 30K. So I'm budgeting between 25K and 30K for this. Right now my options are looking at the Kubota L3940, JD 4320, JD 3720, MF 1547, Case/NH TC45. I'd like to hang around 40 to 45 horsepower. Of course I'd also like to make sre this is the last tractor i buy for a long time.

What kind of issues are they having with the 4000 series? Is that 4x20 or the whole 4000 series of old?

I have had a 4720 for coming on 3 yrs. I love it. I have had a couple issues:

The fuel filler lid is a piss poor design - the pins like to fall out.
Front end loader tab broke off - bad Chinese casting.

I own a 3320 open station for my IL 6 acres. I do not think I would like to clear 15 acres with it. Go with the 4320! Bigger implements available at a not much more cost than 3X20 implements. I do love my 3320 but a 4X20 with a cab would be a dream machine for you I bet. You have a lot of work ahead and the 4X20 is the line to go with!!

My dealer (I should say this is a friend of the family and not just a random dealer) told me that if i was buying a JD to stay above the 60 Hp range. especially with the new JD powertech engines in the 4x20 series. He said since i was looking for 40 hp to go with the 990 if i was to go green.

Can he quantify that? We have heard of very few problems on here.

Is that 60HP PTO or engine?

Pins? MIne just screws off, kind of like the operator some times.

Think i saw a pic of that somewhere. Probably made out of a junked Tata.

The newer 4X20 series have been good in terms of reliability. Some of the early 4000 series had issues when JD was just beginning to produce their own tractor. JD does seem to love their power tech engines but the yanmars have had an extremely good reputation- and much quieter
My loaded 3720 with cab, 300cx loader, 3 rear hydraulics, cruise, air seat, toolbox, front loader hydraulics, side mirrors, vertical exhaust, R4 wheels, mid pto, horn, radio, skid steer attachment, block heater and rear worklights was just over 31K.

Have access to a haybine and round and square baler, but trying to figure out if they will work behind a 4720. Things like having 1 hydraulic handle vs 2, what hoses go where. Cannot remember how large they are but were pulled with a Case cx70 (yes i know a lot bigger but about the same horsepower). I think the hay bine is about 10 ft wide and the baler does about an 800# bale (smallish). I suppose one of the concerns is the weight (?) pushing the tractor around, esp if land is not real level. Have baled some but not with the 4720.

The fuel tank lid screws off.

I am talking about the lid pivot pins vibrate out.

My 4520 seems to work fine with my neighbor's Case (don't know the model) small in-line square baler. I can't really speak to running a round-baler with it, I just don't have experience with those. My guess is that it would be a stretch, but I don't know.

I have the 3720 so I'm more partial to it. Aside from the fact that the 4000 series was a bit bigger than I needed, I stayed away from it for a couple of key reasons. 1) The Powertech engine is made in Mexico. I know that's closer than Japan, but Yanmar has proven itself. 2) Stanadyne makes the fuel system. I know Stanadyne all too well, and feel that their engineering and QC are lacking. I dislike the way these engines start and rev immediately at high fuel. I start my tractor with a quick puff and it purrs.


The Powertech has been pretty good as a wwhole, but we've seen some injector issue (imagine that) and programming updates from what I've seen. I think you'd have to search pretty hard to find a 3000-20 with Yanmar engine or fuel system issues.

How large a tractor you need depends on the intended use. I looked at a cab model, but really disliked the controls. I really only have one issue with my 3720 (aside from the POS fuel door that plages the 4000's also) is that I get air in my hydraulics when the hydro is worked hard. This is reported to be a known issue with some early production units, with no known cause or fix.
