Or With a tractor you can adjust the the amounts of Mechanical advantage you apply to the tool. Think in terms of work instead of raw force. Or in simple terms stick said plow into ground apply force of your thruster horizontally, and the entire rig will rotate on the pivot point you have provided by setting said plow. Apply thrust to offset the torque, then you tend to pull the plow out of the ground. (An bake the ground with the back wash of your thruster) (It helps if you draw a picture) Now Ono I owe you an apology, I scanned your description and hung on the "Plow", Though what you where writing was a Roto-Tiller two similar but different tools. Driving a Roto-Tiller through un-mown brush and grass is an exercise in frustration. But a Grav Roto-Tiller is grandly do-able, as the torque and traction of the tool itself works it's way through. -- Evyn _______________________________________________ GurpsNet-L mailing list <[email protected]> http://mail.sjgames.com/mailman/listinfo/gurpsnet-l
