This often signifies that certain routes or crossings are unsuitable for heavier or slower farm machinery, or conversely, that these vehicles have a specific designated route.

The OB-05 sign means the main sign's rule *only* applies to agricultural vehicles. A sign saying 'Uitgezonderd landbouwverkeer' (Exempt agricultural traffic) means the main sign's rule applies to everyone *except* agricultural vehicles. The OB-05 is a restriction *for* them, while 'Uitgezonderd' is an exemption *from* a restriction.
Yes, often. While the sign itself restricts the main sign's rule *to* agricultural vehicles, their presence implies you should be prepared for potentially slow or wide farm machinery on the road, especially if the main sign indicates a specific route or behaviour for them.
Generally, no. The sign is specifically for tractors and similar agricultural machines. Mobile machines or lorries are not considered agricultural vehicles unless explicitly stated otherwise, so they would not be included under this specific restriction.
