FS25 Soil Draft Physics

FS25 Soil Draft Physics

Soil Draft Physics models implement draft and tyre traction according to real soil conditions and agricultural engineering standards, including ASABE D497 draft and Brixius traction. It uses Precision Farming soil types and soil moisture, but also works without Precision Farming.

Features

• Realistic implement draft for ploughs, rippers, subsoilers, cultivators, disc harrows, seeders and other implements, based on implement type, width, depth and speed
• Precision Farming soil types, from sand → silty clay, with a medium soil used when Precision Farming is not installed
• Soil moisture by soil type, with sand drying fast and clay staying heavy for days
• Tyre traction and rolling resistance based on real tyre sizes, such as 710/60R38, wheel load and pressure
• Automatic tyre pressure based on axle load
• CTIS support with 4×4 Traction System, VarioGrip style
• Fixed pressure on tractors without CTIS
• Tracks supported
• Replaces the game’s own draft force, with no double counting
• Movable HUD: Ctrl+Shift+H to show or hide it, and Ctrl+Shift+M to move it with the mouse
• Settings in modSettings/FS25_SoilDraftPhysics.xml, including intensity and traction scale

Compatibility: Not recommended with Mud System Physics or Tractor Terrain Dynamics. Tyre grip is handed over to them automatically.
