Probably because she beats so many in tractor pulls with it. Secret: 23 degree rib Firestone rear wheel tires. </div><div dir="auto"><br></div><div dir="auto">The 720 LP Std is an anomaly. My only Standard tractor. I ran onto it in OR on the way back from AZ. JD did not make very many, in the 300's, so it really caught my attention. Then when I learned what the asking price was I didn't even bargain. SOLD. Then after the excitement, reality set in. It had 4 500 lb rear wheel weights. 2000 lbs. I instantly realized I didn't own a trailer that could handle the load. So I had to hire someone to haul it for me. </div><div dir="auto"><br></div><div dir="auto">That was just the beginning. I needed to remove the 4 weights. I then found out the hubs were tack welded on. Removed the welds, a several day job, then had to break the sleeves loose on the axle to get the rear wheels off. More days requiring a 24 lb sledge after many other failed attemps. Finally, a week and a half of full days work, mission accomplished. </div><div dir="auto"> The only good thing about all this is I sold the weights for what it cost me to have it hauled. So, I don't want to count the cost of labor in this tractor. And once I got LP in the tank, fixed some wiring and got it timed right it turned out to be a really good running tractor.</div><div dir="auto"><br></div><div dir="auto">The 2520 is a sweetheart. Bought it the same place same day. BAD day for account balances. Have done nothing more than clean it up, change all the fluids and put all new tires on it. I bought it knowing I was going to have add new tires.</div><div dir="auto"><br></div><div dir="auto"><br></div><div dir="auto">I am sure you are enjoying your sweat heart 3010 as much as I am my 2520</div><div dir="auto"><br></div><div dir="auto"><br></div><div dir="auto"><br></div><div dir="auto"><br></div><div id="composer_signature" dir="auto"><div style="font-size:14px;color:#909090" dir="auto">Sent from my Verizon, Samsung Galaxy smartphone</div></div><div dir="auto"><br></div><div><br></div><div align="left" dir="auto" style="font-size:100%;color:#000000"><div>-------- Original message --------</div><div>From: Dean Vinson <dean@vinsonfarm.net> </div><div>Date: 11/23/25 8:55 AM (GMT-08:00) </div><div>To: 'Antique Tractor Email Discussion Group' <at@lists.antique-tractor.com> </div><div>Subject: Re: [AT] Tractor stuff </div><div><br></div></div><div class="WordSection1"><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">Hi Dean. Concerning the 620 I sold, you’ll be pleased to know it’s in good hands: Attached photo shows the new owner, a young guy whose family for many years had operated a Deere dealership in western Ohio and which has a big collection of green tractors that they farm with. The 620 replaced one his grandfather had owned but which unfortunately was lost in a barn fire, so he intends to keep this one for the long haul.</span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif"> </span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">That’s a great lineup of tractors in your photo. The 720 LP Standard would be a head-turner for sure around here, where row-crop and gas or diesel tractors are overwhelmingly the norm. And with the “crowdation” issue you mentioned I bet they draw a lot of interest at shows. And your 2520 is gorgeous.</span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif"><br>I bought the new carb for my 3020 from Robert’s Carburetor Repair, which advertises it as follows: “This is a brand new carburetor made exclusively for Robert's Carburetor by Zenith. This carb used the same molds as John Deere originally did, has the correct throttle and choke linkages (no adapt-a-fit brackets or drilling) and has been modified internally to get rid of the problems the original carbs had with black smoke, fouled spark plugs and over-fueling.” I’m happy as can be with it, although it wasn’t cheap and there was a long lead time to actually receive it. I do still need to go through a winter with it to really know how it’ll perform, but so far it's been just a huge improvement.</span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif"> </span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">Dean Vinson</span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">Saint Paris, Ohio</span><span style="font-size:11.0pt;font-family:"Calibri",sans-serif"></span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif"> </span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif"> </span></p><div><div style="border:none;border-top:solid #E1E1E1 1.0pt;padding:3.0pt 0in 0in 0in"><p class="MsoNormal"><b><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">From:</span></b><span style="font-size:11.0pt;font-family:"Calibri",sans-serif"> AT <at-bounces@lists.antique-tractor.com> <b>On Behalf Of </b>Dean VP<br><b>Sent:</b> Saturday, November 22, 2025 11:22 PM<br><b>To:</b> Antique Tractor Email Discussion Group <at@lists.antique-tractor.com><br><b>Subject:</b> Re: [AT] Tractor stuff</span></p></div></div><p class="MsoNormal"> </p><div><div><div><div><div><p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Helvetica",sans-serif">Dean,</span></p></div><div><p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Helvetica",sans-serif"> </span></p></div><div><p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Helvetica",sans-serif">Good to hear that Green is still the "Go TO" I was concerned when you got rid of the 620! :-) I own mostly two cylinders but own one which is considered a multi-cylinder or New Generation tractor. A JD 2520 and it too is rapidly becoming one of my favorites if not my favorite. I know exactly what you mean about the seat kind of wrapping around you and making you feel more secure. In the past I have never liked fenders but now that I am older than dirt I am starting to appreciate them. But... since have gathered up a little road kill around my waist and an advanced age they sure make getting on and off the tractor more difficult. So.... I finally bit the bullet an installed some expensive steps to get on and off the 2520. It is now my easiest tractor to get on and off of. Maybe that is the reason it has become my favorite. On my two cylinders I have just one step on the flywheel side and no fenders with the exception of the JD 520 which has teardrop fenders. So far I can handle them but I can anticipate where that will become a challenge. Nobody makes a step bracket that supports two steps off of the front side of the rear axle. I may have to buy a piece of heavy bar stock and make my own two step set up. There is a two step set up available but I don't understand why it even exists. The top step is level with the axle. What is needed is two steps to get to axle level. At least that is what I need. Getting on from the back is out of the question and too dangerous because all my tractors have three point hitches. And all kinds of hydraulic levers and outlets in the way. </span></p></div><div><p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Helvetica",sans-serif"> </span></p></div><div><p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Helvetica",sans-serif">Since my collection is now mostly built around Two Cylinder 20 series tractors they have all kinds of bells and whistles that the earlier two cylinders didn't have which makes them have what one of my fellow co-workers once called a "Crowdation" problem. Or more *hit on them than a thanksgiving turkey. To make things even worse I have put front mounted rock shafts on all of them which adds to the "crowdation" I am not quite to the point of having every option ever offered on them but I am getting close. Every once in a while I ask myself:" How did my my collection drift into the 20 series?" The best I can figure out is they were the first Waterloo Two Cylinder tractors that had all the bells and whistles of the later newer tractors with a real conventional three point hitch. And they became available the last two years I was on the farm and I drooled over them but we never had one to run. I asked my Dad why we didn't have one. His response was very direct and pointed: "Son, we are not going to be machinery poor on this farm". End of discussion. The JD 70 got a few more thousands of hours. That 70 got traded in on a JD 3010 in 1962. I can assure you that tractor was completely worn out by then.</span></p></div><div><p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Helvetica",sans-serif"> </span></p></div><div><p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Helvetica",sans-serif">IIRR, the 3010 and 4010 gas had some real fuel system problems when they were first introduced in late 1960 as 1961 models. Again, I think the MS carburetor was the source of much of those issues. Right now I don't remember what the fixes were at that time but I thought all that got resolved by the time the 3020 Gas came out. I'm going to have to find my books and do a little research to refresh my memory. I'm glad your new Zenith carburetor has solved your problems. I wonder if it has had a design changes over the years. Now I know I have to find my reference material on this subject. My 2520 diesel starts almost instantly even after standing for 5 months in the barn every year. I always am amazed by that. The only thing I don't like is the WFE. Most have them but I was raised in Corn and Bean Row Crop environment and all of our tractors had tricycle front ends so that is what I remember and got used to. WFE makes a tractor clumsy IMHO but it seems collectors prefer the WFE. I have a WFE on the 520 too and next summer it will get that changed out to a Roll--O- Matic or single front wheel. The 520 is supposed be a nice little handy, do it all, tractor with one of its main attributes as being very nimble. Once a WFE is put on a 520 that all gets violated. </span></p></div><div><p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Helvetica",sans-serif"> </span></p></div><div><p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Helvetica",sans-serif">Here is a picture of the 4 tractors and two Roll-Over plows I showed this summer at the local shows.</span></p></div></div><p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Helvetica",sans-serif"> </span></p></div><div><p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Helvetica",sans-serif"> </span></p></div><div><p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Helvetica",sans-serif">Dean VP</span></p></div></div><div><p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Helvetica",sans-serif"> </span></p></div><div><p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Helvetica",sans-serif"> </span></p></div><div id="ydpe8018b47yahoo_quoted_4305362360"><div><div><p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Helvetica",sans-serif"> </span></p></div></div></div></div></div></body></html>
