Abstract
An irrigation system is moved with an oscillating trojan bar operating against a lugged wheel. A drive pawl on the trojan bar drives the wheel forward on level ground or uphill. A hold-back pawl on the trojan bar keeps the wheel from running free when going downhill. The detent likewise contains an uphill pawl and a downhill pawl.
