I look at the big 4wds and I wonder if triple tires do very well on all surfaces, or if they are only good for mud. Seems like running triples on hard surfaces might lose you traction since I would think there would be too much weight distribution to be very good. They sure look good with triples on them!.

I was told the triples were to cut down on ground compaction so you did not have to plow deep every year, such as ox plowing or such. Guess it would help with traction also.

I farmer I used to work for had a JD 9400 with triples. It was a very nice tractor to operate. We pulled a V-ripper, 38' JD disk, and a 60' field cultivator. The disk and the field cultivator did not work that tractor very hard. The V-ripper could stop it in it's tracks if you hit a hard spot.

Jonfarmer; Worked for Dankert farm in the
80's,had a J.D.articulated 4 wheel drive
with triples,pulled a pan in the bog pulling black dirt up for New Plant Life.
Was really hard to get stuck,but when you got stuck, might as well hang it up and wait for a BIG wrecker. Also had to be careful turning or the outside tires would
catch and tear lugs off Ken

I used to have a 2470 Case with duals, went to triples on the rear, one really wet year. Only $100 for the wheels, plus some homemade hardware extensions. Tractor would not bog down in the mud- sunk in a few inches and spun- just lifted the FC a bit and it would always walk right out. When I put duals on a combine, a dealer cautioned me about the extra stress it put on the driveline- but agreed when I told him that getting stuck puts a lot of stress on as well. Haven't broken anything yet on two different machines.

Three tall narrow tires have less rolling friction than two wide tires while having the same ground contact area. In snow for instance while spreading manure in the winter. The taller and narrower the tire, the better traction they had. A very wide tire works best in sand where there is no bottom. In soil where there is dry loose soil on top and firmer soil below. Taller/narrower 45 degree lugs and accepting the fact more wheel spin is required to remove the loose soil in order to get a grip on the firmer soil below. There is still a school of thought out there that believes that any wheel spin while pulling heavy draft load sin loose soil is a waste of fuel and productivity. Isn't so and has been proven by tire companies in test after test. You cannot add enough ballast to stop wheel spin. Without causing even worse soil compaction and wasting fuel pushing that increased rolling friction and hauling that extra weight around. Want to seen how much power is required to just move a tractor across a field? Take a small tractor and try hauling a large tractor across a ploughed field. A 40HP/6000lb tractor can get maxed out hauling a 120HP 14,000lb tractor. That's fuel burned that doesn't work the soil. Some farmers get an ego thing going on the width of their field equipment, whose is bigger. Many times a size or two narrower and shifting up a gear or two would cost less and achieve more.

The taller tires I can understand, since the taller the tire, the more ground clearance you'll have, and narrower tires are know to give you more traction on hard surfaces, but you'd lose the benefits of the narrow tires when you put a bunch on. I also see some super singles, which I wonder how those do?.

Looks like those huge timberjack tires used for logging in the bush. The specs are on the Firestone ag tire site.

The unit in that picture is being used for fertilizer spreading in Vermotville Michigan. It is a place called Lime&Gypsum Products inc. Pics are in the farm trader on page 86.

Triples are actually not very good in mud. They tend to plug up in between and act like a big slick. The reason for the triples is because these 500 hp tractors now have about 100 lbs of weight per horsepower and it actually takes that much tire on the ground to capture all the power of the engine itself. With just duals you could end up with a tremendous amount of wheelspin pulling a 50 foot field cultivator with 500 hp. Awesome looking beast aren't they! I would love to drive that beast.

So the 800 metric duals alot of them have are barely enough?. I love the big machinery so even though tractors such as this don't exist in my area yet, and I say yet because lately the corperate farms have been expanding further and buying bigger toys, I love looking at them, and I'd like a chance to try out one of these 500hp bad boys, I'd especially love to take it to the local farm pull and enter it into the free for all just to see how awesome the pulling power is, I downloaded the Nebraska tractor test results on the 9620, and it's got a drawbar pull of around 51,000lbs, fully weighted, which is just incredible.

I have a friend that sells them for a living and he is always giving me the low down on those things. He has done it so much he gets a little bored with it but I turn into a 10 year old any time I see one of those things. He said it will set you back about $235,000 plus about $15,000 more if you want a 3 point hitch and about $15,000 more if you want the fancy powershift transmission. He had all kinds of options for it. A 51,000 pound pull is pretty unreal. I had a chance to spend some time around a Big Bud during the 80's that was being used for tiling that was 525 hp and weighed around 50,000 lbs. Funny, it still couldn't pull the tile plow if the conditions got really muddy. Had a 8430 JD on the front of it sometimes. Most of the guys have gone to tracked machines again with great success. I saw a tracked Case IH go by the house the other day with a double fold 50 ft field cultivator that was unreal. We all stopped what we were doing in the yard and watched it go by. They look funny on tracks because they don't bounce. Just smooth like they are on railroad tracks. It was huge though. Later

My neighbor just bought 4 new Deere's and 8 pull pans. That gives him a total of 10. The oldest has 9,800 hours on it and never a problem.
