What is your learned opinion on what a JD 720G Standard (wheatland)will tip the scales at? The one I saw was equipped with pretty wide rears (at least 18") and one set of rear wheel weights.

This thing is a brute. What really struck me was how massive the front axle was.

I'm guessing 8,200#.

I have a 720 std gas w/ 1 set rear weights and 18.4x30 rears no 3 pt(dont think this option was offered on this tractor) weighs 7490 w/ me (170lbs) and about 1/2 tank of gas

If ours didn"t have three sets of weights on the rear, it would be close to 7500 lbs. It is an original paint diesel standard with rockshaft (no 3PT) and 15-30 original tires.

We did see an original paint 720 G standard pull once that had a single front wheel on it. It looked weird. I do not remember the class though.

When the tires of my 620 standard were 75% full of fluid, it was 8100 pounds. Now with out fluid its 6980.

To those used to seeing Standards. A wide front rowcrop looks like a gangly thing that will snap off on the 1st good bump. The round tube wide fronts are even more awkward looking than the squares. Looks more like an Oliver than a Deere. The Standard's platform sheet metal gives better protection and operator room as well. The Standards look much better than the rowcrops too. The rears are likely 23.1x26 which are intended for loose soil. Not worth beans to pull on hard ground. If the tires are dry, then about 8100 with rockshaft and pto plus wheel weights. Depends a little with regular or heavy swinging hitch, battery size, fuel load, operator etc. Some of those western tractors were shipped with just four tires, steering wheel, seat and a drawbar. 8000lbs is lots for 55HP on a 2WD bias ply tire tractor. Getting a lot of HP loss from rolling friction with those wide tires on loose soil.

AND it only takes about five times as long to work on them because of all of that guarding that makes them pretty!

Thanks.

Your figure corresponds to what I was thinking. And yes, now that I'm picturing that 720 Standard in my mind, the rears have to be 23.1--they are big.

Is there any way that tractor so equipped could get under 7500#--say remove the 3 point?

Sounds like you have visions of tractor pulls ? JD 2cyls. are just built too heavy to compete against something like an oliver or minie mo. on the track they belong in the field where they will out pull most anything.

Yes, I have visions of tractor pulls, but it's not what you think.

At a recent pull that I participated in--7500# Classic Division, 2.5 MPH--some guy got in line with his 720 Standard to run in that class. That tractor looked too darned big to be in that weight class.

The odd thing about the whole situation was that I was running the scales for this pull. When I wasn't at the scales, my brother was there. Neither of us remember this guy running that 720 across the scales. On top of that, I was LOOKING for this 720 as I had gone against him last year. We didn't see it until right when it was time to pull. Hmmmm...

The point is moot however, as he was bested by at least two other tractors. I was prepared request a weigh-out if he had won.

Maybe he did weigh in. All I know is that I didn't weigh it, and neither did my brother. And maybe that 720 will go under 7500#. It doesn't appear to me that it is that light, and your responses seem to support that.

Thanks

I think he bypassed the scales as it would be hard to get that light with a standard tread JD.Of coarse he could of removed half the innards and had custom castings made from aluminum.I have heard tales of this. Those JD standards were in there hey day in my area, Ohio, soon after they were made. That's before my time but I saw pictures of them in an unlimited weight class. Picture an 820 JD with 2 homemade platforms from front to rear one on the bottom and one on the top.Pile them high with anything you can find.Alot of oilfield bits piled on,wheel weights too! I don't know how much they weighed in at ? Now in the early 90's I saw a stock 72hp late 820 weighted to 10,000 lbs. get beat bad by a souped up Farmall M that weighed alot less 8,000 lb maybe.This was just at the end of the local pull just for fun. My cousin owned that 820 and said he felt real bad getting beat by that little tractor,until he saw the inside of that M engine years later and how much work was done on it.

Out in the field with in dirt the 23.1x26 720 will out perform a 70 rowcrop wearing 15.5x38's.And compact the soil less. On a hard clay pulling track? The rowcrop's tall narrow tires will walk all over the standard with short wide tires.

That's why they made duals for when they we weren't being used in R-O-W-C-R-O-P-S.

Still, tough to cultivate with a standard.

C'mon, Glen....you've driven them, too. HA!

BTW, how much did the Rowcrop chassis outsell the Standard by?

I bet you had a Betamax, too!

I purchased a JVC VHS for Christmas in 1984 during the peak of the VHS v.s Beta wars. Still have it and it works great too. We keep a little 50 rowcrop for wee jobs and scuffling corn. A large diesel tractor like a 70/720/730 diesel should stand steady on four solid feet. Not looking like a kangaroo with a heavy back end and light weight front. The distribution of chassis types seems to reflect a lot on the opinion of upper Deere brass and what to ship to the branch warehouses. Atlanta got 49% of the 435's for reasons nobody knows. For some reason Canadian 50/520/530's are rollo-matics. A wide front 50 is unheard of unless imported by a collector. Diesels were standards. Lots of corn in rows here. Mid size 60/620/620 and gasser 70/720/730 were an equal mix of standards or rollo-matic.

"Mid size 60/620/620 and gasser 70/720/730 were an equal mix of standards or rollo-matic."

You know I'm just trying to try your patience, but I really would be surprised that this statement holds up. Are you talking shipments to Canada, or overall production? Because I have seen a LOT of 60 family and 70 family tractors, and I could count on two hands the number of non-row-crop (meaning includes a narrow front or and adjustable WFE) chassis out all of them. Sort of like the "A" vs. AR-AO production. THousands of RC's vs. std's.

Just curious.

Shipments to Canada. Standard 60/620/630's all over the place. BTW, as for the Dubuques. Crawlers are around, but not common. The standard and utility chasis were about it with the odd T in both wide and narrow fronts. T's mostly in tobbacco and tender crop areas in southern Ontario. The W chassis is rare unless it's a 435. Yet the W was the most common wheeled chassis. V & H chassis and LP fuel unheard of. If somebody brought home a brand new diesel 70/720/730 narrow front in the 1950's. The community would show up to see such an odd sight.

That's interesting. When I was a kid out on a drive with the folks, if you saw a "Wide front end" tractor, everyone would look. Western Ohio and Ontario isn't that far apart, yet the crop mix might have been such that you guys used the STD"s and we used the RC's.

Joe,

Having a 720 diesel myself I pay close attention to all the 720s that I see. A friend of mine pulls a 720 gas rowcrop w/narrow front and can easily get down to 7500. When my diesel had 15.5 tires on it i had it at 7650 and that's with a pony motor. I would think that the extra shee metal adds maybe 150 lbs and that stout wide front weighs about 350 to 400 lbs more than a rollomatic front end.

All in all, I would assume that a 720 gas standard with 1 set of wheel weights would have a whole lot of trouble weighing anything less than 8000. Although I have seen a 70 diesel standard compete in 7500 classes before with no weights. That is allowing 75 lbs grace at the scales, but he does have a pony motor that will outweigh that set of wheel weights. He could be honest, but I doubt it.

How did the W9 do this time around? When can I read about it on your website? Inquiring minds want to know!

WELL....SINCE YOU ASKED...!

The W-9 is and remains the reigning king of the 7500# Classic Division at the Hartford Fair. She went 146 feet with a Case 300 at a distant 123 feet. I think the 720 Standard spun out at just under 120 feet.

I managed to find another set of rear weights this year for the W-9 but still was giving up weight to the other guys as it weighed 7246. The extra weight made a significant difference from last year, but she still spun out in 1st gear.

I don't know if Mars was aligned with Jupiter when IH laid out the geometry of the hitch...whatever. That thing just gets sucked down hard on the track and just gets with the program.

After the pull, some of the Clubbers went to the far SE cormer of the Faigrounds to mess around with our tug sled. We stacked a JD 60 and 50 on the sled and hooked the W-9 to it. It went merrily on its way down the crude track along with six guys that jumped on the sled. I figure total weight including the sled was right around 14,000#. My brother totally flipped out over this performance.

Needless to say, I had the fattest head in Licking County, Ohio at the end of that day.

Joe,

That's good to hear. Now maybe you should find a few more weights and bring that thing to Portersville, PA next year for the King of the Mountain pull. They pull a stone boat sled like you guys, they just end up with about 25,000 lbs on it!

The W-9 looks pretty sharp. Why didn't the infamous 450 try to give you some competition? There is a W-9 at one of our local pulls that does fairly well. The later versions such as the 650 really do good job in the 12500 lb class.

Hey even if you guys are stricken with the red disease, I enjoy your website and your stories.

720Deere: thanks for lurking on our website. I've not paid much attention to it lately, and it's in dire need of some updates. Also need to rid out some dated and stale features.

Thank you--the W-9 does look pretty good in pictures. Just don't view it close up. It really doesn't have the best paint job in the world and the surfaces weren't prepped all that well.

My brother did run his 400 (painted like a 450) in the 7500# class against me and went 115 feet before fouling out on the left chalk line. He was running real light in the class though at 6750. Why he didn't throw on the extra two pairs of wheel weights we have before the pull is beyond me. The 400 ran very strong. We call it a Super 400--it has hi-comp 450 pistons.

I acquired the W-9 somewhat by accident two years ago at about this time in August (it's a long story). I got stuck with it, hated owning it and wanted to unload it to anyone that was interested. As it turned out, there were no takers when I was in the selling mood. If I had gotten rid of it, I would have missed out on a ton of fun. That thing has been a blast.

Joe,

I knew there was a hitch with the 400/450 thing, I was just too lazy to go back to your site and get it right. Even a 400 when setup properly should give that W9 a fit in a light class like 7500 lbs.

It's funny that you say that it pulled to the left as I have a friend with a 450 that does the same thing. Every time the going gets tough, it pulls left. Of course he never has enough front weight and those deluxe IH brakes aren't much help with steering under load. LOL! I have tried to help him figure out his problem to avail for several years now. I was talking to his father one day and he told me that the left rear tire had flat several years ago and he never put the CaCl back in the tire. Since then we have tried to get him to either fill the tire back up or put more wheel weights on the left side. He won't do anything about it and still curses the tractor for it's behavior.

I don't know what the heaviest classes are for you guys, but you should try the W9 in a heavier class if you can find some weight for it. Those big tractors are really fun in the heavier classes.

The heaviest class in the pulls (ALL TWO OF THEM!) I've been in top out at 8500#. My brother, Mike, is getting his crotch damp with the thoughts of more weights and running the W-9 in the heavier class. He's pretty confident the 9 would have faired well in that class, too.
