Road trip

Mine is turbocharged and intercooled and I typically run about 4-5 acres per hour in corn and it burns about 2 gallons per acre. So maybe 10 gal per hour-but I would expect to use less gliding down the road.

I would expect it will take you 6-7 hours to get home, and probably use 60-70 gallons at most.

I am sure you will be fine, I feel a lot more safe taking Diesel down the road than gas-just quit less. But I would still have a follow vehicle with extra set of fuel filters, gas can, and basic set of tools. May try to leave at first light to get as many miles behind you before any traffic starts.

Good luck!

The Model 7700 is also about 1-1/2 to 2 MPH-- slower than the faster Model 6600. If memory serves me right, I'm thinking in the neighborhood of 16 MPH. No, it won't eat the fuel used in harvest, and should be reasonably economic.

Also, I do want to emphasis this. While fire is still a combine's No.1 enemy, road accidents are the second highest cause of combine mortality! Think about it. 85-95 percent of a combine's running time is in the field. The secondmost killer is roading/transport accidents and that occurs withing that relatively small time.

Lastly, I want to discuss travel speed. While the top speed of 15-25 MPH [combines] may seem like a very slow speed, just bear in mind, that to a combine, 20 MPH is like your car's or pickup's own top speed of about 120 or so MPH. Just as with cars, the faster combines travel, the the more room for errors and overcorrections.

The other thing I love about the Model 7700, is the fact that it IS STILL a big machine! Nevermind successive models have somewhat dwarfed the 7700, this model is still as big as it ever was and to this day, can still cut the same 100 acres/day as before. Actually, before the debut of the Massey-Ferguson 760 in 1972, the John Deere 7700 was the largest combine in the world! Think about that. For 8 more years, it was second to size only to the Model 760, too!

As above posts, make sure you check fluid levels and rear axles, wheel bearings etc. Maybe jack up and spin rear wheels to make sure bearings are tight. Take off hubcap and run grease through grease zerk on hub until you see a little grease coming through outer bearing.

No problem with any wear on combine, it has this gear in it so it is designed for road travel. The problem with road travel begins if you have a full hopper, which is a no-no. If you have a narrow header to leave on the machine it may ride better and give you less drive tire bounce.

Get a Gazetteer map and plan your route using less traveled county roads which may save you miles also. There are many great county roads that are better to drive on, people you meet are used to farm equipment, and you will see more country also.

Best wishes.
