  • My Father (in Minnesota) has a 1960 (about) John Deere 730 Diesel with wide front, electric start, 24 volt system, JD fenders with lights, live hydralic, live power take off, dual hydrolic system, JD 3-point hook-up, power steering, good rubber on tires and overall is in excellent condition. He is 76 years old and is starting to think (typical farmer) about retirement. Can someone give me an idea of what this tractor is worth? He has received some inquiries about selling. Thank you.

  • I would appreciate anyones commwnts about my 720 diesel standard with pony start. What size disk should I expect to pull in sandy soil cutting heavy grass? What is your advice changing the plugs in the pony next to the driver. What type of oil do you use in both engines. Will iy hurt this tractor to work at an engine speed of 600 rpm for 6 hrs at a heavy load such as disking at 6-7 mph. Thank you.

  • Looking to buy a 730 diesel in the west coast. Not picky about the front axle configuration. Prefer elect start, 3 point and in good working condition. Restored is fine but not critical.

  • 730 JD; Kathy Hudson since your tractor runs like new you could restore it to different levels. For instance; 1960 361CID gas 59hp lo 2750 med 4150 hi 5320 1960 376CID dsl 59hp lo 2740 med 4175 hi 5300 If it has good rubber, looks sharp and purrs like a large bore 2 cyl kitten you combine that with good sales ability and you will do just fine. The new owner will be getting a solid value with decent tractor performance once you peak up your JD 730.

  • The 730 is a really nice tractor. My father-in-law aold his and has regretted it. I currently have three B's, one M and an AO. I would like to score a 730 or 830 with electric start that is located on the west coast. Any leads would be appreciated.

  • Robert, the 730 series used the exact same engine as the 720. According to the "Official Nebraska Test #594" the diesel 720 had 58.84 calculated belt hp. The serial numbers for most of my ready to hand sources show ; 1958 7300000 to 7303760, 1959 7303761 to 7322074, and 1960 as 7322075+. However, these numbers indicate build date, NOT model year. Just like the car guys, you could get next years model before it was actually next year. Accordingly, there are really only 1959 and 1960 model years. There were a very few 1961s all built for export only. Your electric start 730 diesel came with four (4) SIX volt batteries. This was because four six volt batteries together are more powerful in terms of cold cranking amps (cca) than any two 12v batteries that would fit in the box. The ones in my 730 are rated at 650 cca for a total of 2600 cca. I have not found any 12v batteries which exceed 1300 cca, so my tractor has four batteries, just like it was originally equiped. Hope you enjoy! Jim

  • TO;ROBERT EASTMAN THE 720 HAS ABOUT 68 HORSEPOWER. YOUR 720 MAY HAVE A OIL-TYPE AIR FILTER AND IF YOU LOOK CLOSELY THERE SHOULD BE A KNOCK-OUT FOR THE ABOVE HOOD TYPE. GREEN MAGAZINE AND TWO CYLINDER CLUB WOULD BE SOMEPLACE TO LOOK FOR ANY PARTS OR MANUALS. IF YOUR TRACTOR IS LIKE THE ONE IN THE PICTURE THEN I WOULD SAY IT IS A HIGH CROP MODEL. YOUR TRACTOR HAS A 24 VOLT TYPE STARTING SYSTEM. JOHN DEERE CAN HELP YOU WITH WHAT TYPE AND SIZE OF BATTERIES TO USE. ENJOY!!!!!!

  • I now co-own a #730 diesel wide front by John Deere. I went to an auction to buy an early Ford tractor, the kind that I leaned how to drive on when I was a boy. When I saw the #730, and in a remarkably good condition, I had to have it. Those of you who went through the collecting of 60s muscle cars, as I did, know how this feels. I have some questions for anyone who knows this type of tractor. It was built in 1958 or 1959. It is the 2 cylinder type of diesel with the 24 volt electric start, and the compression release pedal start. QUESTIONS; What is the horsepower rating on this tractor? Because it has the wide front and is quite tall, is this considered to be a "row crop" tractor? Or a "high crop" tractor? The hood has no provision for an aircleaner to be extended through the hood. Is this unusual or is this incorrect? There is no hole in the hood where there should be one for an aircleaner extension. I have purchased the tractor in just the past few days. I would appreciate any help with suggestions for manuals for parts, service, or owners manuals. I have found a listing for some on the antiquetractors website. I'm sure those will do fine, but any additional suggestions will be welcome. This is my first tractor, and I have a long way to go to learn how to properly maintain it. In the small town where I live, there is a John Deere dealership and service center. A big reason why I chose John Deere over other quality brands. If I need to, I can drive it over to the service center, or for really big problems, they can come get it with truck and trailer for a short haul. Also, what batteries should be in the tractor? I know that it takes two 12 volt batteries. The ones that are in it look small. The ones that are in it seem to be doing the job, but there is a CENTRAL TRACTOR/FARM AND COUNTRY nearby. If I were going to buy new batteries, what part # with what features would you recommend? Also, the matter of cold weather starting. So that I do not "have to reinvent the wheel", what methods work for you? I have ruled out the use of eather because of the extremely thin "squish" area of the pistons to cylinders clearance. Serious damage could occur. I have my own ideas. I think that this is quite enough for my first letter. A BIG THANK YOU to the Tractor Shed for this forum, and to its' readers.
