Realistic Harvesting V1.6.4.1

Realistic Harvesting for FS25 adds dynamic harvesting mechanics based on crop density, cutting width, moisture, machine horsepower, and mechanical calibration.

Features

• Physics-based engine load and speed: Ground speed dynamically adapts based on harvested crop mass (t/h), header width, and vehicle horsepower. Overloading the engine or using incorrect settings results in real grain loss.
• All machine types supported: Fully calibrated physics for Grain Combines, Forage Harvesters (chaff/silage), Root & Vegetable Harvesters (potatoes, beets, carrots, parsnips, spinach, peas), Cotton, and Sugarcane.
• Interactive Combine Calibration (RShift + K): Calibrate Rotor/Drum RPM, Concave Clearance, Fan Speed, and Sieves for each crop. Correct settings ensure maximum yield and minimum loss.
• Workshop Upgrade Packages (Tiers 1-4): Upgrade your combine at the shop.
• Level 1 (Standard): Fully manual operation.
• Level 2 (Sensor Kit): Displays calibration guidance hints (low / optimal / high).
• Level 3 (Yield Monitor): Real-time yield (t/ha, bu/ac), area rate (ha/h), and moisture telemetry.
• Level 4 (Opti-Harvest AI): Automatic settings calibration and automated speed management.
• AI & Courseplay compatibility: AI helpers and Courseplay workers automatically utilize your saved profiles or optimal calibrations.
• Draggable HUD: A movable on-screen display showing live Engine Load, Productivity (t/h, ha/h), Crop Loss %, and Moisture.
• Global Crop Profiles: Save your tuning once, and profiles automatically load across your combines and savegames.
• 3 Difficulty Modes (ESC Settings): Arcade (relaxed), Normal (balanced), or Realistic (strict physical limits and penalties).

Changelog

• V1.6.4.1
  • FIXED: Harvester calibration hotkeys (Shift+K), HUD toggle (Shift+H), and Harvest Diary (Shift+J) response when attached implements (headers/cutters) are selected in the vehicle tool chain via native interaction and activation flags.
  • FIXED: Modular harvesters and system carriers (NEXAT / NEXCO) threshing system classification. The NEXCO combine module is now accurately recognized and displayed as Axial Rotor instead of falling back to straw walkers.
  • FIXED: Live harvest telemetry, speed regulation, and header lowering detection on modular multi-vehicle and gantry harvesting platforms where cutters are mounted to the motorized carrier rather than the threshing module directly.
  • IMPROVED: Expanded automatic combine classification for modded and serial grain harvesters, adding support for Torum, Gleaner, Tribine, New Holland CH Crossover, Case IH AF series, and classic conventional harvesters.
  • IMPROVED: Deep 3D model node inspection (i3dMappings) for custom modded combines that lack standard animation tags, ensuring machines with physical rotor or axial components are reliably identified.
  • FIXED: An issue where switching between combines, for example from Tier 4 to Tier 1, left the calibration terminal (Shift+K) bound to the previous machine, falsely displaying Tier 4 settings.
  • FIXED: Shift+K calibration terminal failing to open on modular carrier harvesters whenever an attached header/cutter implement was selected.
  • REMOVED: Grain Threshing Subtypes. Removed the division of grain combines into walker, rotor, and hybrid subtypes, unifying all conventional grain harvesters under a single "grain" standard.
  • REASON FOR REMOVAL: Fragile name-matching lists and complex XML animation node lookups frequently failed on modded combines, causing false classifications, XML callstack warnings, and inconsistent power balance. Unifying grain combines into a single robust model guarantees 100% stability across all vanilla and modded harvesters without affecting forage, root crop, or specialty harvesters.
• V1.6.4.0
  • New Features, Threshing Mechanism Classification System: Implemented an automated classification engine in rhm_Combine.lua that classifies harvesters into 6 mechanical categories based on vehicle XML data, wheel count, and chassis dimensions:
  • STRAW WALKER (conventional straw walker combines).
  • AXIAL ROTOR (single and dual longitudinal rotor systems).
  • HYBRID APS (accelerator pre-separation cylinder with twin separation rotors).
  • FORAGE CHOPPER (precision-chop drum and accelerator systems).
  • ROOT HARVESTER (lifting shares, sieving webs, and cleaning rollers).
  • SPECIALTY (cotton, sugarcane, grape, and olive harvesters).
  • Added a real-time Threshing System Indicator badge to the Shift+K calibration terminal header.
  • Added public API endpoint RHM_Api.getThreshingType(vehicle).
  • Added localized naming across all 27 language files (translations/l10n_*.xml).
  • 3-Way HUD Work Rate & Productivity Monitoring: Implemented interactive click-cycling in Yield Monitor HUD Cell 7 (expanded layout) and Cell 4 (compact layout).
  • Cycles between: Processed Area (ha / ac) <-> Instantaneous Work Rate (ha/h / ac/h) <-> Session Average Work Rate (ha/h / ac/h).
  • Added session average work rate telemetry to the Trip Statistics frame.
  • Added public API method RHM_Api.getAverageHectaresPerHour(vehicle).
  • Improvements & Optimizations, Native GIANTS Engine 10 Cutter Specialization: Migrated cutter logic into an official GIANTS Engine 10 vehicle specialization (rhm_Cutter), completely replacing runtime monkey-patching of Cutter.onLoad.
  • Registered <specialization name="rhm_Cutter" /> in modDesc.xml and dynamically injected it across all cutter vehicle types.
  • Differentiated Power Balance and Moisture Physics: Differentiated base driveline drag according to threshing architecture (8.0% for straw walkers, 9.5% for hybrid APS, 11.0% for axial rotors, 10.0% for root harvesters, 9.0% for forage harvesters).
  • Refactored moisture processing drag in RHM_LoadCalculator.lua: straw walkers receive an exponential resistance penalty in damp, clumped straw mats, whereas rotary systems maintain steady crop flow with lower specific moisture resistance.
  • Differentiated moisture separator loss rates across mechanism types.
  • Multiplayer Telemetry Synchronization: Added high-frequency network stream replication (onWriteUpdateStream / onReadUpdateStream) for burned fuel, average speed, average engine load, all 5 loss breakdown reasons (speed, settings, moisture, wear, slope), and concave clearance.
  • GUI & Telemetry Responsiveness: Reduced analytics and trip refresh loops to a 250ms cadence with explicit open/close reset handlers, resolving frozen telemetry values.
  • Upgraded throughput monitoring to simultaneously display instantaneous peak and session average throughput (t/h).
  • Bug Fixes, Modular Carrier & Gantry Combine Support: Resolved an issue where harvesters mounted as detachable modules on motorized gantry carriers displayed zeroed HUD telemetry and failed to record odometer trip data.
  • Implemented zero-allocation implement tree traversal (rhm_Combine.getAllAttachedCutters) to discover cutters attached directly to the carrier chassis.
  • Updated cutter working width calculations, weed biomass sampling, cruise speed regulation, wear loss calculations, and field tracking across modular equipment configurations.
  • Crab-Steering & Diagonal Motion Handling: Fixed false-positive reverse detection on vehicles equipped with crab-steering, all-wheel steering, or wide-span travel modes where local chassis Z-vector displacement is non-positive despite forward directional velocity and active crop intake.
  • Ensured active crop flow acts as an immediate bypass for motion direction validation.
  • Cutter Lowering & Working State Detection: Fixed an issue where rigid, non-hydraulic implement attachers failed the recursive getIsImplementChainLowered check.
  • Switched cutter lowered validation to direct implement state (cutter:getIsLowered(true)) with direct joint check fallback.
  • Added a carrier ground speed fallback in RHM_DraggableHUD.lua when an attached combine module reports < 0.2 km/h due to decoupled root nodes.
  • Engine Crash Guard & Dedicated Server Permissions: Added strict type validation (type(flag) == "number") prior to invoking vehicle:raiseDirtyFlags(flag), preventing native engine bit32.bor crashes.
  • Fixed Dedicated Server permission validation in RHM_Settings.lua by evaluating g_currentMission:getHasAdminRights() alongside g_currentMission.isServerAdmin.
• V1.6.3.2
  • Headland Speed Governing: Fixed an issue where harvesters remained speed-locked at harvesting crawl speeds (5 km/h) during headland turns. Lifting the header now immediately releases the motor to full maneuvering speed (15-20 km/h).
  • Implement Chain & Hydraulic Verification: Prioritized authentic feeder house hydraulics (getJointMoveDown, getIsImplementChainLowered) over unfolded header states (Foldable:getIsLowered), preventing wide and draper headers from falsely reporting a lowered cutting state when lifted.
  • Dedicated Server Live Telemetry Sync: Replaced unsupported bitwise operations with native GIANTS Engine 10 methods, fully restoring real-time network stream replication for engine load, throughput (t/h), yield, and recommended speed on multiplayer clients.
  • Automated Helper Synchronization: Added synchronized header start/stop for helpers when separate header launch is active, and resolved live driver handover telemetry resets.
