Question by: Norm B on Jun 13, 2025, 7:04 AM
Motor's rated at 705 newton metres of torque, is that enough grunt for running a wood chipper or heavy-duty trencher off a hydraulic system?
Answer by: Customer Support on Jun 14, 2025, 4:15 PM
For trenching and wood processing work, 705 Nm is a solid torque rating and falls well within the range that handles those kinds of demanding, load-heavy applications. The 4000 Series was built with exactly that type of equipment in mind, mowers, trenchers, wood product machinery, so it's not being stretched outside its intended use. The Geroler design also helps here because it maintains efficiency under load better than older gerotor styles, which means you're getting more of that rated torque actually working for you rather than getting eaten up by internal losses.
