Your tractor finally feels the soil. Implements pull harder in heavy wet clay than in dry sand, and tyres grip according to their size, load and pressure.
Realistic implement draft (ploughs, rippers, cultivators, discs, seeders) based on agricultural standards
Uses Precision Farming soil types and soil moisture (works without PF too)
Tyre traction and rolling resistance from real tyre sizes, wheel load and pressure
Automatic tyre pressure by axle load, with CTIS support in 4×4 Traction System
Clean, movable HUD (Ctrl+Shift+H show/hide, Ctrl+Shift+M move)
Beta version – feedback and log.txt are welcome!
Implement draft and tyre traction based on real soil, using agricultural engineering standards (ASABE D497 draft and Brixius traction).
Draft force per implement type (plough, ripper, subsoiler, cultivators, disc harrow, seeders…), width, depth, speed
Precision Farming soil types (sand → silty clay); works without PF using a medium soil
Soil moisture per soil type (sand dries fast, clay stays heavy for days)
Tyre/soil traction from real tyre sizes (e.g. 710/60R38), wheel load and pressure; rolling resistance in soft soil
Tyre pressure from real 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 (no double counting)
HUD: Ctrl+Shift+H show/hide, Ctrl+Shift+M mouse to drag it anywhere
Settings: modSettings/FS25_SoilDraftPhysics.xml (intensity, traction scale)
BETA: feedback and log.txt welcome. Not recommended with Mud System Physics or Tractor Terrain Dynamics (tyre grip is handed over to them automatically).
BETA 2
BETA 0.7.3.0
Traction force and rolling resistance now act in the correct direction, regardless of the tractor’s orientation
Implement wheels now use their own calculation (no Brixius traction; rolling resistance only when the implement is raised)
Automatically disables itself when MoreRealistic is active DUE TO INCOMPATIBILITY, WITHOUT PROBLEMS EVEN IF IT IS ENABLED IN THE MODS
Settings are automatically reset to the new values
