Good to know before you buy

An operator's manual is for running and looking after the machine: controls, daily checks, service intervals, fluids and simple fault finding. It does not cover strip-down or overhaul.

This copy is the web edition of the John Deere operator's manual, saved to PDF. The content is the same, but the layout is plainer than the printed book and it has no printed book code on the cover.

The engines in these tractors are the PowerTech 2.4L and 3.0L. The engine repair manual CTM301 is also in the store.

Common questions

Does it cover both PRT and HST tractors?
