This mod prevents hay already collected in a forage wagon from being overwritten by grass or by another hay type.
Features
- More of the same hay type collects normally.
- Normal grass is ignored while hay is loaded.
- Fresh Clover and fresh Alfalfa are ignored while hay is loaded when those fill types exist.
- A different hay type is ignored while hay is loaded.
- Empty wagons and wagons containing non-hay material retain normal game behaviour.
Supported hay types:
- Hay:
DRYGRASS_WINDROW - Clover Hay:
DRYCLOVER_WINDROW - Alfalfa Hay:
DRYALFALFA_WINDROW
- Confirmed working on Castlereagh with the Pöttinger 8450 Windrower and Fliegl Cargos 9500 mod wagons.
BETA 3
- Fixed hay being replaced by grass when collecting mixed windrows.
- Replaced the previous pickup-area check with protection applied directly to actual material pickup.
- Added a safeguard against queued material changing the wagon’s locked fill type.
- Protected small loads below the game’s normal fill-type change threshold.
- The first supported grass or hay type collected stays locked until the wagon is emptied.
- Matching material can still be collected; incompatible grass/hay remains on the ground.
- Supports grass, hay, and registered clover/alfalfa windrow variants.
- Added limited log messages showing when protection activates and blocks incompatible pickup.
