The “def pack” mod is recommended to simulate the new def systems.
The “def pack” and “variable tire pressure” mods can be used together without compatibility issues.
Two photos added showing the mods tested on a multiplayer server.
More translations are in development.
Your engine wears out. Your oil gets dirty. Your turbo breaks down if you never perform maintenance. This is what “realistic maintenance” should have meant from the start.
Hyper Realistic Maintenance 2 adds a deep, continuous mechanical simulation to all motorized vehicles in your save game—tractors, trucks, combine harvesters, and cars—with real gameplay consequences, not just cosmetic numbers. What is simulated
Engine: 5 independent components (cylinder, piston, bearings, crankshaft, valves) that influence one another—cylinder wear increases blow-by, which contaminates the oil and further accelerates wear.
Thermal: coolant temperature rises with load, and the engine overheats if the radiator is degraded.
Fluids: oil level/contamination and coolant level—both checkable and requiring maintenance.
Transmission: wear on the clutch, gearbox, turbo, and battery/starter motor over time.
Breakdowns: probabilistic failures that increase sharply once the relevant component exceeds ~35% wear—critical overheating above 118°C is guaranteed, not left to chance.
Vehicle-specific behavior: tractors, trucks, combine harvesters, and cars wear down at different, realistic rates.
Real effects, not just cosmetic ones
Actual power loss—reduces the engine’s effectively available torque; you’ll feel it in the field.
Real no-start conditions—a dead battery or worn starter motor can actually prevent the engine from turning over, accompanied by an on-screen warning.
Combine harvesters lose actual threshing efficiency as the engine’s condition deteriorates.
Scheduled maintenance, just like in real life
10 maintenance items (engine oil, filters, hydraulic/transmission oil, coolant, grease, belts, and more), each with its own interval and real cost to the farm—automatically adjusted based on the vehicle’s actual power. Neglecting maintenance for too long accelerates wear by up to 120%.
3-page vehicle HUD—overview, detailed engine diagnostics, and maintenance status—with adjustable positioning in the game’s Settings menu. The game’s own repair screens (shop, farm workshop, mobile workshop) now also perform a full HRM2 service.
Compatibility: works entirely standalone. If you also have the 4×4 Traction System mod, the two automatically detect each other, and driving with 4WD/differential lock has a real, additional effect on the drivetrain. Significantly improved multiplayer, tested on a real dedicated server (see changelog for details and known limitations). Maintenance progress is saved with the game save.
V1.3.0.0
the new features were added recently, so they may still contain values that are not quite realistic. This aspect is still WIP and will be updated as bugs or more accurate values are detected
new icons added to the dashboard to identify DEF regeneration or clogging
Rated power (hp) shown on the speedometer now reads the actually purchased engine configuration, not the base one.
DPF regeneration RPM increases/decreases smoothly, rather than instantly.
New Workshop (single window)
Replaces the old sequence of several chained windows with a single window containing all maintenance requests, schedule, breakdowns and general service in one list.
Each item shows its category (e.g. [Service] Engine oil), the cost, and two YES/NO buttons side by side for you to choose.
A quick diagnosis is shown at the top (e.g. There are active breakdowns deal with them first), along with the vehicle’s overall health.
The total to pay and estimated downtime are always visible and updated in real time as you select items you no longer need to leave the game to find out how long the tractor will be stopped.
Opens with the REPAIR button in the game’s native workshop, or via the hrm2Workshop command.
New Fleet Panel
Lists all vehicles on the farm with HRM2, sorted by urgency (breakdowns and overdue maintenance first).
Shows an image, name, health percentage and summarized status for each vehicle, with a button to open that vehicle’s Workshop directly.
Opens with the F9 key,
New simulated systems
Air intake filter gets dirty during dusty field work; reduces power, increases consumption and darkens the smoke. The Air filter maintenance item already has a real effect.
Hydraulic system the pump and hydraulic oil wear out when using heavy implements; extra consumption results from drag caused by the degraded pump. The Hydraulic filter/Hydraulic oil items already have a real effect.
EGT + regeneration duration on the dashboard appear only during DPF regeneration and disappear when it ends.
Actual interruption of DPF regeneration switching off the engine halfway no longer freezes progress; it really cancels it, and each interruption slightly dirties the oil (just like a real engine).
Recalibrated power modes
Eco mode recalibrated for a more realistic reduction (-12% instead of -20%), close to what real tractor economy modes offer.
Fixed an artificial inflation of engine load that made the turbo and sound seem more strained in Eco than in the other modes (the opposite of what was expected).
NORMAL icon, more representative of what the mode actually does.
Extended support
Self-propelled sprayers and fertilizer spreaders are now recognized and handled by HRM2 (previously they were completely ignored). other vehicle classes will be added in future updates
