there was a Horizon programme on BBC2 last week about gravity and our efforts to understand it and its effect on time. It got me thinking...
If a tractor and heavy trailer was transported to, say, the moon where there is less gravity would the tractor find it easier to pull the trailer? I'd say yes because the trailer would weigh less.
What about driving a power hungry implement like a forage harvester in zero gravity?
And finally what about soil engaged implements? You would need gravity to provide weight to provide traction, but would you even need the traction?

i am assuming there is air for the internal combustion engine to function?
would have a nice power to weight ratio if it could run,
the flywheel on the chopper would be proportionaly the same as the hp/tractor.....so pto implements would not change......but the product you feed into it would be lighter
you might have trouble getting the cultivator in the ground,

would the profile of the cultivator tine not pull it into the ground without gravity?

depends on the wieght of the cultivator, what is changes is air and gravity
the physical characteristics of the machines have not changed, everything is proportionally lighter because gravity is less
dude, where ever you getting it from at the mo, stick to dat dealer, its working

i forgot
if you assume the cultivator weighs something, it should engage the soil or crater, because there is some gravity on the moon
now if the cultivator goes into the moon, to the same depth and the consistency of the topsoil or moon is similar to earth, you will need more traction to pull the same implement, cause the ground pressure excerted from the tractor is less due to the effect of gravity on it,
how big was the battery and motor on the moon rover way back then??
my suggestion is a fendt or belarus is the best choice of tractor for the moon, down pressure hyd would be a good idea, or a hyd top link, tripples and 4wd for wheels, and lead filling the tires

dude, where ever you getting it from at the mo, stick to dat dealer, its working ;D I like to think of it more of an active and fertile mind ;D, it is winter and there is more time for the mind to wander... oh yer, he does very reasonable rates and has an outlet in your neck of the woods, I'll pass on your details |

You would need to put a heavy oil in the engine...........otherwise it would float away

Seems Doc is off to the moon for testing devices. ;D Happy people, which don´t have any other probs then thinking about working in zero gravity.  I will search the phonenumber of Neill Armstrong. He has been on the moon and has driven a car there. |
