Is there a free wheel lock out on these rollers. I got drum drive but no rear wheel drive. Thanks again.
I don't know the answer to your question but I do have some anecdotal information. I used to rent an I/R SD70 from a friend/competitor. Whenever we tried to load it onto my dovetail trailer (it had steel angle iron on the dove tail -steel angle iron + steel roller drum= no traction) it would struggle to climb up the dovetail. It seemed to me that all the propulsion came through the front drum. I now own a Bomag BW177-4 and it is a much better climber in all situations.
