  • I have a JD 720 deisel with a pony motor. I loved the pulling power of the tractor. It s been setting for a couple of years now in need of tender loving care. I don t work on tractors, and it s expensive to restore. I can t get the switch to the pony motor to work.. or it would start. I think the clutch needs to be adjusted right too.

  • Istarted farming in Missouri in 1970 with a 720 it was a outstanding tractor we farmed 200 acere with this tractor with very little problems. The 720 diesel still holds the Neberaska fuel useage study pulling a 4 bottom 16 plow it would only use about 3 gal a hour.

  • We own a 720 Diesel with pony motor start. It runs and drives well. We will be pulling it in a 8500# no turbo class tonight in Baraboo, Wi. We have owned this tractor almost since new. Many years it was our #2 tractor. Then after some time we left it on the mounted corn picker. Used it to open fields for a pull type. Then retired it to the rear of the shed. We have not ever had it in the shop. Mabe we will o/h it in the future. I repainted it a few years ago so it looks good. My son has it cleaned up and running good. Wish us well tonight. I know we will be up against everything with more power. But we will have fun..

    R. McCormick wrote on Sunday, February 01, 2009 (PST):
  • My Dad had a 730 diesel with the pony engine start, although he always called it the pup engine. Perhaps that term was just a Southern Ontario ruralism. In my opinion, that tractor was the absolute pinnacle of John Deere s output; nothing after comes close. There is no sound more nostalgic than the one produced by pushing its throttle ahead under heavy load. Add the smell of burned diesel fuel and dirt and I m a kid again.

  • I have a black dash 720 diesel in show condition with electric start & origional wide front but I recently noticed I am getting fuel in the crankcase whether running or not. Has anyone had this problem with a 720d?? It runs great, has great oil pressure and plenty of power as I have pulled it twice along with my other brands of tractors and done very well. I recently got a diagram of the possible leaking locations and found this was common problem on the older JD 80 diesels. Any comments or possible easy solutions to this problem would be appreciated as I am reluctant to tear into this problem without help.

There is some pictures in the october issue of Green magazine under "720 keeps busy". Right now I am buying cows and hope to buy or rent a farm in the near future.

We just got done putting all new oil in it. We are going to restore it this summer. But we are going to work it hard first. But I can't wait to restore though. THANKS

  • I have owned 2 720's in the past 10 years and both are a joy to operate. There is nothing like the lugging power of this JD on a 3 or 4 bottom plow in heavy soil.
    RV Kerns wrote on Saturday, June 22, 2002 (PDT):
  • I own a 70D with wide front, 800A 3 pt and long axles with dished wheels. This baby sings. Friend told me of when he was a younger man that he had a 720D and his brother had a 560D ih. Both pulled the same # of bottoms in the gumbo in the Mo river bottoms. The 560 would try to run up and over him but when he hit a tough spot, the ole 720 just kept going but the 560 hit the ta and still lugged down, sometimes having to stop and shift. Fuel consumption is the most economical of any tractor built in hp versus work done versus fuel used. It took a yanmar (jap) engined subcompact tractor in 1984 to beat it. Nothing can touch a deere. Competetion is nice but ya gotta give up sometime. Deere is the only manufacturer to still be wholey it's own. When they make machines like the 70/720/730D that still out perform a lot of newer makes, well keep trying. Yes, they are not as handy or fast as some of the new stuff but for the price, nostolgia, resale and value they deliver, the only tractor that could eclipse it is the 4020.

  • I have a John Deere 720 propane and John Deere 60 gas. The 720 needs some attention as I am dealing with now. I would like to possibly buy another one in time. I really enjoy it,as I do farm a little bit and use this tractor for most of my plowing and disking. It needs some powersteering work and I just had the starter rebuilt and put a taper lock flywheel on it.

  • I grew up on Larson Farm in New Milford CT and all we had were John Deere tractors. We had a 720 D electric start row crop that just wouldn't quit. Peter traded it in at Riva equipment in Cannan for a 2020 that I still use. I would love to find that 720 and bring her home again. The only thing on it that stands out is the front housing was missing a piece of the casting by the impliment mounting bolts. I would imagine the tractor went to western mass, eastern NY, or NW Connecticut.

  • Seeing all the comments on the 720's pulling power reminded me of one that I farmed with during the sixties. We had a new '61 JD 4010 pulling a spinner moldboard with 3 sixteen bottoms in a field following harvest. We were plowing in fourth gear at a depth of about 7 to 8 inches. I wanted to see how the 720 would do and went over and fell into the furrow behind the 4010. This surprized the hired hand but he didn't stop. At the end of the half mile through, the 720 was about 6 lengths behind. Granted I had to keep the 720 real hard at work. The gear on the 720 was just a tiny bit slower and this caused some of the distance. I think the 4010 diesel was and is one of the finest tractors I ever drove; I know the 720 was not in its power class, but It was about as I had figured it to be. Ever wonder which one would outpull the other at the drawbar? I wondered also and my brother and I hooked the 720 to the 4010 with a big chain. I pulled the 720 in 2nd, idled down, he was going to pull me backward with the 4010 in 3rd. I was a little anxious before the start since I didn't have any wheel weights on the 720', the 4010 had two to each wheel. I pulled him all over the place. We tried three different times; same result. When daddy came in and saw the tracks where the 4010 had be dragged, he wanted to know "What was going on out there?" He of course was afraid of a tractor rearing up, but we rode them every day and were too good to have let that happen. I'm retiring the last of this year and am moving back to the contry, got the place bought already, and the first thing I will do is have a nice shop built where I can work on tractors. The second thing is to buy a 720/730 diesel. The 4010, super 88, M-5, M Farmall, UTU (I like punishment), and 1800 Oliver will come asap. I must be crazy, those AC D17s are even looking good to me as well. Well, maybe a Ford, v8 powered would top off the collection. Enjoyed just thinking about the old times. John

  • I purchased a 1959 730 diesel in 1996. It must have been mistreated for many years before I got it. After many hours and tearing it down completely and rebuilding it from the ground up it now runs like an ox. I understand why many folks are proud of their tractors. In a parade last memorial day weekend an older fellow smiled and gave me the thumbs up with a tear in his eye. That made all the hours of working on it and money spent all worth it. I love the sound they make under a load, that bark gets louder. I first heard a two cylinder diesel at two cylinder expo in 1995. I knew then I wanted one, and next year at age 26 is when I purchased my tractor. After 2 1/2 years of work it was complete, only I strongly recamend not restoring a tractor this size in a two car garage.

  • I have two 730Ds electic start and two 720D one direct start and the other one pony start and a 620. I will be selling a couple of the tractors and I don't know which except one of the 730 will not be sold as it is perfect. One of the 720s the pony start looks like a new tractor as it only has 990 actual hours on it and for the past twenty year was owned by a collector that only showed it. I don't want to sell but my wife thinks 5 tractors is a little much for nine acers. They are the best they made and for the money you can not beat them for working.

  • I cut teeth on a 70 gasoline at 12 years old on our western North Dakota sugar beet farm, but when I worked for my uncle one summer he had just got a new/used 720 in its finest paint. I ran this tractor most of the summer plowing a field of alfalfa in gumbo. We had a two bottom spinner plow and ran in fourth gear if I remember right. The land owner insisted that we run his IH 560 gasoline with the 720 -- no contest and what a long locomotive it was. The only way the 560 could keep up was to use the torque amplifier jusdiciously. I also had the distinct honor of starting the 720 diesel backwards twice that I can remember. First time was a real shocker when the oil came flying back in your face from the air cleaner; of course my uncle swinging his arms crosswise took a little figuring out. Loved starting it with the pony motor and there is nothing like hearing the 720 idling in the farm yard while eating a great noon meal. And lugging power - wow! You could lug it down to two pops a second.

  • My father and I own a JD 620 witch runs great for not being a diesel but it steers extremely hard because of the manuel steering. We were wanted to know if it was possible to covert it to power steering? If possible how difficult would it be and what would need to complete it? Or if any one knows how to free up the steering so it will turn easier. We have tried every thing we can think. If any one has any ideas please write back. Ps- we would much rather have the power steering.

We have only had 4 snowfalls of any significance but to go out in the still of winter, be it night or day, with our JD 630 and plow the driveways in our rural area is a much better alternative than watching tv. The gentle popping sound in the clear cold air is like ....a symphony.

  • The 720 diesel has got to be one of the best row crop tractors of all time! If you don't think so give one a try. I have had the privilage of growing up on a farm in the 70's and 80's with a late '58 720D row crop. This tractor is a wide front, pony start work horse. My 720's flywheel came loose in about '93 and my dad left it parked for several years. In '97 my dad told me that if I could get the tractor running I could have it. The 720 was soon hauled across the state to my small farm where I now live. I installed a taper-lock flywheel and rewired the tractor to get it to run. But, as they say that is only part of the story I could talk about this tractor for hours. I dont know why the pony engines always seem to get a bad rap, my pony engine works good and it is still on six volts. I guess there aren't many people out there who love to here a two cylinder Deere started with the little pony ; but I sure do. Most people of my generation have never heard a 720D pulling a one-way sunk to the spools or turning a mixer-mill but boy, have they missed out. All the green blooded boys from where I come from will tell you that a two cylinder diesel says dawnk-dawnk-dawnk not pop-pop-pop like the gassers do. Thanks for the great picture and website.

  • I have been around the two clyinders all my life. The first thing I would try is turning the pressure up a half turn. The next thing I would do is change the oil and filter some times the filters get pluged. If your main bearings are bad you should feel signifant end play and up and down play when the clutch is fully engaged. If all that checks out you probably need to rework the head mainly valve guides. and when you have the head off you will be able to tell if it needs rings.

  • oil pump is the bottom of the oil pan. Is engine oil going down? If so, crank shaft seal could be leaking oil into transmission. Also could have bad main bearings, that is why it loses pressure when it is warm.

On hot days when clusters of gnats would swarm over the hood I discovered that depressing the valve de-compression pedal, causing thick black smoke to roll out the exhaust would quickly disperse the little rascals!
