What must you check when fitting front ballast weights (Frontgewichte / Frontballast) to a tractor before driving on public roads?

1. The weights may be carried loose in the front loader bucket
2. The weights must be securely locked in place, must not take the front axle beyond its permitted load, and must not obscure the front lights or indicators
3. Front weights may exceed the front axle rating provided the rear of the tractor is also loaded
4. Front ballast weights must be removed before driving on a public road
