Rivers, MB | We have a 375 quadtrack and looking at buying a 9520 wheeled or another quadtrack. Have been told that if you get a wheeled tractor w/ 800/70R38's ballasted properly that it will cause equal or less compaction than the tracks? Looking for hard numbers. Hence my last post with weight on a 9520.
Can't seem to find the footprint of 800's and 710's online anywhere. I know its there, just can't find it. Need that to do some calculations. Anyone know the footprint of dualled 800/70R38's and 710/R42's are? or 520R42 triples. |

Charles City. Iowa | Look at New IF Michelin Ultraflex tires. Michelin says it will Equal a track time will tell.

| Every area is different and has different soil types but I talked to a guy that farms in the very SE corner of ND (red river valley gumbo he called it) and has a quad and says it workd great for tillage espically in the fall for heavy tillage but in those soil types do NOT put it on a no-till drill to seed soybeans into corn stalks as the weight is so great that and compacts the ground do much in a small area that the beans do not grow well in the wheel tracks again this is probally a situtation that only happens with certain soil types/condition just pointing out it can happen. |

Rivers, MB | We seeded with a quad this year for the first time. Probably the muddiest/wettest seeding conditions we've ever had and had the best germination we've ever had, especially in the "wheel tracks". I'm sold on the tracks concept, worried about maintenance. Thinking about being half pregnant by having one quad and one wheeled version.

WC MN | I agree mennoboy. Planted beans into cornstalks with tracks and tires and if the situation was that the tracks were backing it that much then duals or triples would have left two or three tracks instead of the one the quad left. If you fight mud in spring or fall on any regular basis tracks are a good option. We run cats now and would never go back to wheels. Seen first hand times when cat will march up and down the field while the wheel tractor does nothing but spin. If you are running an air seeder, the quad may be a better option do to its ability to turn and not leave and berms and turn better around corners with seeder in the ground. |

| I just looked in my firestone book, 800/70R38 load index 173B tires have 725 inches of flat plate area at 23 psi. So that is about 5800 square inches on the ground. So a 53000 lb tractor will have about 9 lbs per square inch. I am guessing that a quad track with 30 inch tracks has 5 ft of track on the ground. 4 tracts so that is 7200 square inches on the ground. 53000 lb tractor will have about 7.36 lbs per square inch. Just some facts I have know idea what that means in terms of what is allowable for soil compaction.

NW IL | We ran 800's last year and I was happy with the flotation, however that is 4 tracks 30" wide. Twice the print of a quad with 30" tracks.
The web site below can give you tire comparisions. Just enter the tire size and click on show matches.

Rivers, MB | Can you check the flat plate area for 710/70R42 and 520/85R42 's. That would be muchly appreciated.
Thanks

Rivers, MB | well that explains it! On the computer......... never thought of that! :)
I found that page this morning and tried it and couldn't get any info. thought i must be doing something wrong. Tried it this evening at supper, nothing. Tried it now, now i get info that helps. Don't now what I was doing wrong.
Thank you

Manitoba, Canada | haha! bugger when that happens eh?
Michelin used to have pretty good tire specs online, and now they seem to have them hidden away. Maybe I just dont know the right button to press?

Manitoba, Canada | For what its worth... I have a HARD time believeing any theory that a tractor with 800's can be better for compaction than a quad. I dont know the exact numbers but I believe each track has over 2000 sq in of soil contact. I could show you lines in my wheat every 40' this year at harvest time from a tractor with tripples pulling a salford in the muck before seeding. The quad pulling the seeder through the muck was fine, it was the Nh3 tank that would leave ruts and stunt germination as bad as the trippled tractor did. My opinion of tracks is if you NEED them for the conditions you are running or for traction/power then you pay for them. They will cost you more money to run, you charge that against the cost of needing them. If you do your math and you can budget to keep a newer quad around and try and keep it less than 2500 hrs, I dont think you will have much higher maintenance bills than tires. If you dont need tracks for what your doing, tires still go round and round. When shopping for a used tire tractor remember what the price of tires have done in the last 6 months...

ND | One thing to consider in the track vs. tire comparison, is the width of the area of ground affected. What I mean is that a tracked tractor with 30" tracks will affect essentially 60" of ground each pass. A tractor with 800s will affect a much wider area. While its possible that the ground pressure per sq. inch could be less under the 800s, you should also consider the width of ground affected on each pass. The importance of this issue in large part depends on the ground and the type of application you would be using this tractor for.
Just my 2 cents, in the Red River Valley where I farm, tracks seem to work better in most applications for us. Best of luck in whichever choice you make! |

MN | another thing to consider is that the track might be 30 inches wide but its also long (60+?) so there is more surface area in contact with the ground then on a 800 or 850 tire. yes the tires are also very wide but the point of contact is probably only 12-15 inches in length. thats why tracks float |

Lincoln, Ks. | But what happens when your tires get worn down and you have more slippage. The more slippage the more compaction you will have. I have a 65c with over 6000 hrs and still have the original belts, they are worn down but still don't pack the ground. |

Brazilton KS | We have certain fields which are like that. The double coverage from the quad trak makes too many lug prints and it just gets too hard packed. Single belts don't do it as bad, but even with them it's best to just drive between the rows. |
