hey guys I was wondering what everybody is runnin for weight in your big row crops. I've got an '84 8070 MFWD. It's got fluid in the main drive tires in the rear, a full set of iron hanging on the front, and fluid in the front tires as well. The ol' girl is getting 4 new shoes in the back next week and I was considering having the tire shop pull the fluid out of the fronts. This fall I ran the chisel without duals and really didn't notice any difference in slip, actually I've never noticed any slip, even with bald rear tires. My thinking is that a little slip on a 32 year old front diff. Wouldn't be the worst thing in the world. This is just my 4th season farming, so I'm hoping somebody with a few years under they're belt could tell me if I'm thinking correctly, or if I'm about to make a mistake. Also, about how much does the cast hub for the spin out rear add for weight, and do you guys figure that into the equation as well. Thanks |

Asking about weight is about like asking if a ford or chevy truck is better... That said i am a fan of keeping them on the heavy side. I would ask was the tractor setup the way it is to work the same type of ground you have in the past or did you move the tractor to a farm with a different soil type? If the front end has been working well with the weight it has on it I would tend to say leave it alone and move the fluid to the new tires. It does sound like a lot of weight but I am guessing they put it on for a reason. My personal opinion is that weight either by loading tires or wheel weights is much better then weight on the frame. I would guess the front wheel weight has more to do with keeping the front end down on the ground while pulling than slippage. Just guessing. But frame weight tends to be much harder on the wheel bearing then wheel weight. |

I think slippage is something that is real hard to perceive.When you have a radar gun and a new digital dash, you can really tell what is going on. If you are tilling that flat black Illinois dirt and can do it without duals, more power to ya  It will always be easier to add fluid later than take it out in my opinion.

| we put 4 new tires on the back of a 1586 several years ago. Bill had to throw some more weight on the front, cause the front was floating all over the place, I do not know what you are pulling- may want to leave it in there for now. |

| Small world. Yeah I gotcha with the ground speed. I use a hand held GPS to see what's really going on, and there was no difference in speed from the previous season when I was chiseling with duals. I'm the second owner of that orange beauty, and the previous owner dealt with a lot more hills than I'm currently dealing with. He also used it to pull wagons to town. I currently use the tractor to pull a 25' cultivator, a 9 shank 1500 chisel plow and a 21' disk |

We have 10 weights on the front and 1100 lbs of rear wheel weights (each side) on our 8070 MFWD. Have not used it since we put the weight on the back but without it, it slipped quite a bit this fall. ------------- ryan 1984 8070 FWA,1979 7060,1975 7040,1971 190,1960 D-17D,1957 D-14, 196?

with what you are pulling, I'd leave out the fluid. There is nothing harder on a drivetrain than locking it down to the ground. Running these older tractors works great, and keeps costs down, but I'd rather let it spin some than tear up the drivetrain. Tires are much cheaper than tractor parts, some which are no longer available, so they have to be cared for, and pampered lol! ------------- 210 "too hot to farm" puller, part of the "insane pumpkin posse".

| Leave the fluid out. Front end will cost you $$$$ if you have to rebuild it. |

We stopped using fluid when we went to radials on the 7060s. I had three 7060s, the first one we put radials on my tire guy convinced me not to put fluid back in. It surprised the heck out of us when it would walk away from the other two with the same load. The 8050 and the 8070 have full front weights, no rear weights and no fluid in the tires. I have 18.4 R38s on the 8050 and 20.8 R38s on the 8070 can't remember what is on the fronts. Radials all around including the duals, they pull a 27' field cultivator and a 5 shank ripper with no trouble. ------------- AGCO My Allis Gleaner Company |

Too much weight cuts fuel economy and available drawbar pull. You should have at least 5% slippage for maximum fuel efficiency. However, with a MFWA, you do need to stay below 15% to avoid hopping.

| Thanks for the feedback. I think I'm going to go with my gut and drain the front tires. I really want to keep that front diff. Happy. The tractor goes in tomorrow, I'm excited to see it. Nothing better than a tractor, or truck with new shiny beefed up rubber under it. |

| It might be worth putting in tubes anyway that way if you find you miss the weight you don't have to break the tired down to add it. |
