The two machines have significantly more power than their predecessors, which makes them the best performing dozers in their respective classes. The PR 724 Litronic has a service weight of 35,264 lb and a 160-hp engine, and the larger PR 734 Litronic has a power output of 200 hp and a service weight of 48,490 lb.
