Step 1 Before starting
Before you start a trailer, you must know the basic safety procedures. These are safety checks and safe stop.
Always use safe stop:
You need to take extra precautions when safe stop is not possible, for example when using power take-off (PTO)-driven stationary machinery such as slurry tankers or operating external controls.
Step 2 In position
A tractor can only be safely operated from the driving seat. You must know how to get in and get out safely, how to adjust seats and mirrors and how to recognise controls so you are always in control of your tractor.
Some tractors have controls mounted externally to aid hitching (normally on the rear mudguard) – you will need to take different precautions when operating these.

Step 3 Under power
This step is about getting the engine started and making sure it is safe to begin work. This is the time to check the brakes, the steering and other controls. Also check that no one else is in danger from your tractor.
