this is a very back wards way of doing it, but it should work,
get a old live PTO tractor, lock out the clutch, and lock in the PTO, use a wheel hydraulic motor to drive the PTO shaft of the live tractor, thus driving the tractor by using a flow control valve on the motor one should be able to dial in the speed you want, thus keeping the engine disengaged from the then pull the tractor powering the roto tiller and steamer,
about the only other way would be to take an old tractor and put in a few extra transmissions speed reducers,
another possibility is to make a "new rear axel" using a couple of irrigation gear boxes for circle irrigation, there 50 or 52 to 1 reduction and drive them by hydraulic motor, may need to use some additional gear reduction, a walking sprinkler uses a one and half electric motor and a center gear box guessing 30 to one, to the out side wheel boxes that are 50 to one,
one could even use a eclectic motor and a percentage timer on the control powered by a generator, the axel could be lowered hydraulically and lift the tractors axel off or enough weight off so the creep axel can make traction,
one other idea would be if your doing straight lines is to winch it for forward motion,
that is what come to mind,
at one time there was a company that made tractor mounted trenchers, Auburn trencher, and they made a transmission unit for some tractors that would give them a creep speed, the one I saw was driven by a hydraulic motor, and the other (I have was gear) never did get a tractor to fit it, the hydraulic would be most likely slower,
