Why is the engine revolution not smooth on my Kubota Tractor?
- AAshley SmithSep 8, 2025
An unsmooth engine revolution in your Kubota Tractor can arise from several causes. A clogged or dirty fuel filter (replace) or a clogged air cleaner (clean or replace) are common culprits. Other potential issues include a fuel leak due to a loose injection pipe retaining nut (tighten retaining nut), a malfunctioning injection pump (repair or replace), incorrect nozzle opening pressure (repair or replace), or an injection nozzle that is stuck or clogged (repair or replace). The governor may also be malfunctioning (repair). In addition, worn turbocharger bearings or a bent turbocharger shaft (replace the turbocharger assembly) or turbocharger fin or other part damaged due to foreign matters (replace the turbocharger assembly) can be responsible.
