Torque/Angle question

["Steven W. Reilly" <luckyone@sentex.ca>]

I have a question and I don't know if I have the right answer or not; 
perhaps the list could answer.
Lets say I want to move a 3000 lb load up a 10% grade.  This load is 
suspended on 32" tires.    How much torque (at the shaft that directly 
drives the tires) would I have to produce in Ft-lbs to move the load up the 
slope?

I keep getting 1250 Ft/lbs, is that right?

Thanks,
Steve
