To your tractor you have attached a hay turning machine that projects a long way to the back. Who could be endangered by this when you take a left turn?

You answered correctly. When turning left with an attachment that extends behind your tractor, vehicles alongside you on the right and pedestrians on the right-hand side could be endangered. This is because the rear part of your attachment can swing out to the right as you turn, potentially hitting anything close on that side. Vehicles behind you are not at risk from the rear swing during a left turn. Always be aware of your machine’s overhang and ensure the area to your right is clear before making the maneuver. This helps prevent accidents and protects nearby road users.
