aldot, can you post pictures of this please? As far as I know there is no workshop manual for the mower - only an illustrated parts list that isn't much help here - so we need to use either people's prior experience, or just inventing a solution. The pictures will enable others who have similar mowers to tell us how their decks are supported at the front. Obviously you have to end up with the deck level - it is just a matter of what the missing front support should look like.
