logging tractor
« on: February 20, 2009, 03:30:48 pm »
Thinking about upgrading my "red" tractor to "green" and see there are a very large number of John Deere 4720 listings.  It is 58hp w/4wd and looks like it only comes with the hydro drive (3 ranges, separate pedals for forward & reverse).  Since this model was only started in '05 it must have been very popular.  Any feedback on this model would be appreciated.  Thanks, Al

If the tractor is going to be used for logging you might want to think about getting a skidder instead.  A lot more stable and designed to take the abuse of the woods.

Look to see where the hyd filter is.On some it's under the floor board. ::)  A real good place to hit it with stumps and rocks.You will need to buy the protective cage for it.

1938farmall , If you're thinking of buying the JD 4000-20 series models look at the 4320. I think it has the most bang for the buck. JD used the same engine for the 4120, 4320, 4520 and 4720 but just tweaked the injectors for more HP. In my opinion the more you tweak an engine the hotter it runs for the same grunt, which results in less engine life. All four tractors are the same size frame but different HP.

I would not want hydro drive in the woods...

I like to set the hand throttle to a certain speed and usually you are in the lowest two gears on the low range...

Once you have the gear selected for the hauling conditions and the hand throttle set you can
adjust the rev slightly with the foot throttle once in a while.

I like to just grind and roll along slowly and not to have to keep pushing with your foot on the hydrodrive foot control when the machine is bouncing around on rough ground.

Its much different from running a back hoe or a tractor in  field work when you a skidding with a tractor in rough woods conditions.

And not to just be different, but I think hydro in the woods is the best game in town, compared to gears. Hands are free to run the loader and 3pt., move branches out of the way if needed, and scratch an itch, or just chase bugs away from the face and wipe the sweat off ;D ;D.

And there is cruise control with Deere hydro, so having a steady speed with no foot usage is an easy choice if tired on the hydro pedal. Sometimes I use the cruise in the woods on longer runs, but not often.  Also this Deere has load match, so that is handy too.
Just my opinion.

Not heard of any hydro users that go back to gears.  :)

The Deere 4000 series has Deere diesels too, not Yanmar.

 i got a jd 5325 4 wheel drive with a front end loader this is about 60 hp if you are getting a jd just to pull and load logs i think a skidder or something else would do better the jd the hyd connections for the loader hang to low  if you have not a weight box on the rear and try to pick up over 2000 lb the read of the tractor comes off the ground if you try to raise the bucket or forks on unlevel ground it makes the tractor top heavy the old farmall with a pto driven wench would be just as good as well as being a lot cheaper :) ::)

I don't think a hydro is the way to go either.I put my tractor in gear and set the throttle and go.My hands are free to run the loader and 3 pt too.Once I have the winch up and get going I don't touch them again until I get to the  wood yard.But most times I just keep one hand  on the wheel all the way.I just go at a steady speed.I'm in the woods with mine just about every day off doing something.I do have another tractor that is hydro and like it for what I do with it,it never goes in the woods to be worked hard.

Zopi , thats highly debatable. ;D ;D

Concerning choice of tractor size.  It depends on size of logs you are trying to move and other tools involved.  I don't have alot of experience moving logs with tractors, but I have some.

This is my humble opinion; the more weight and horsepower the better for straight dragging. I used my MF 263, of about 62 horsepower to move most of the big logs after the hurricane.  The Massey weighs close to 7000 pounds with ballasted tires.  I would put a chain around the big end of a log and pick up with the 3 pt hitch.  Then pull.  Most logs I moved were at least 24 inches diameter.  That was probably the smallest tractor I would want to use skidding logs.

The tractor front end often came off the ground if I went to fast or on rough ground. 

I didn't have my 4020 at the time but it is much larger and I am sure would have done a better job.

Now I think if you are using a log arch,       weight isn't as important if on flat ground.  A small tractor on steep slopes will get pushed around by the weight of logs. Ask me how I know ;D
Tractor brakes are designed to stop the weight of the tractor and a reasonable load.  I personally wouldn't want to move alot of logs that weigh more than my tractor. 

I looked at the 4720 specs on the deere site and it shows a weight of 3700 lbs.  Seems a little light to me for logging, although 4wd will help if you can keep the front wheels down. 

For probably not much difference in money I think I would go with a larger 5000 series tractor.

Hope that helps some.
I know there are folks with alot more experience than I.

Man going from red to one of them green things is like shootin ol yeller. I know a lot of guys use tractors for logging but skidders are for logging tractors are for farming. I started on a blue tractor with a farmi winch that worked good. After a small dead tree along the skid road fell across the tractor seat knocking me out of it I went and bought a timberjack. I didn't get seriously hurt from that tree but it could have been real bad had it hit me square. I lived and learned. You can get a real deal on a skidder now. When I bought mine I only paid 9 grand and put it to work. That was in 1989 and it's still going strong. Get the right tool for the job.

3 ranges, separate pedals for forward & reverse

What you describe here sounds a lot like the Clark skidders we had. They where a 3 speed power shift with a torque converter.
I would think the JD Hydro would work much the same way. It would let you control your speed well going through rough terrain. And start the pull on a heavy load easy, so as not to shock the drive-train.
The only disadvantage I know of for the hydro's is they do not like plowing and disking all that well. They can build a lot of heat in the transmission on steady all day pulling. Plus in order to make them work right in the hard long pulls, you need to keep the engine at near max rpm's. But for shuttle/loader work and varying speed work they are great.

I skid with a M6800 Kubota and a 601Farmi 3pt winch. It has a hyd shuttle clutch, so that takes the load off the trans on the start of a hard pull. When I bought it I was looking for a power-shift of a hydro. None of the large names built one at that time in a 68hp. What you are looking at sounds very intriguing.
As you already know from using your current tractor, sticks can take out a lot of vital parts on a tractor compared to a skidder.

The other brand to look at and see what maybe available is Fendt. They have a lot of CVT transmissions. I just did not have a dealer in my area. Hopefully I have answered some of your questions.  :)

There is another option, it's ORANGE. Been using a Kubota M4700 for several years, it does everything I need. Most of the Kubotas mentioned on here are the L series, a little on the small side for skidding. M's can be had with 100 hp and more. On tractor skidding in general.... For use as a skidder, 4 wd is pretty much a waste, if you have a front loader, then it's worth while. Most folks will tell you to put a belly pan under the bottom for protection from stumps and limbs. I say don't, the downside of belly pans is they get full of leaves and debris which gets soaked with diesel fuel and oil, then catches fire and burns the whole machine to the ground. Just watch what you run over. OK, so I might bust off something, I can fix that, kind of hard to rebuild a burned machine. I don't use chains to hook the log, a good set of skidding tongs is a good investment. Just make sure the tongs are attached to the 3-pt up high enough that you can lift the end of the log a few inches off the ground. Dragging a log through the woods with the front edge digging in the dirt and roots is an accident waiting to happen. I have a home-built hydraulic winch mounted on the 3-pt hitch, only use it when I can't get the tractor close enough to the log to use the tongs.
Yeah, a small skidder would be nice, but it won't load the logs on a trailer, or haul off a pile of slabs, or put a log on the mill. For us po-boy part time operators a well equipped big-enough tractor is a very good compromise

I prefer hydro for most things, and have no problems whatsoever with it in the woods. Hydro can allow you to do some things that just can't be done with conventional setups. Working on very steep slopes with positive control for one, like setting a tree in a planting hole. I have a Farmi winch, and my L48 does a fine job with it. You do loose some power, but it isn't really an issue in my opinion. As for color, well, that's personal preference. ;) I pulled these two 40'+ red oak logs out with ease.

My old IH 656, although not ideal for wood work, works well when it's not too slick or hilly. My dad built a heavy duty crane-type attatchment for the back. It works very well.

It has hyrdo drive. It's the kind that you control with your hand, just put it at the speed you want and leave it. It's very handy. It also has a clutch, for whatever reason. The hydraulics can lift quite a bit too.

Biggest log I've pulled with it was a 20" diameter 40' walnut, didn't have much trouble, except trying to get it around a sharp bend. :D
Not sure why I didn't cut it into shorter lengths. I guess I'll attribute that to limited experience at the time. ::)
