Realistic Mechanical Systems gives every Farming Simulator 25 machine real mechanics, including parts that wear out, fluids to monitor, and breakdowns that warn you before they fail. It supports tractors, harvesters, trucks, and electric machines in single-player, multiplayer, and dedicated server games.
Features
- Up to 8 systems made up of the machine’s real parts, from the injector to the PTO bearing.
- Fault warnings include fluctuating engine speed, black, blue, or white smoke, turbo whine, and recurring rattles.
- Breakdowns can spread when warnings are ignored. Overheating the engine, continuing to crank the starter, or bending the driveshaft too far can cause parts to break.
- Check fluid levels, top them up, blow out the radiator, and grease every point with the grease gun.
- Flat batteries can be started with jumper cables or the jump starter.
- Engine oils are available from Motorex, Motul, and FUCHS. Engines with AdBlue or a particulate filter require the right oil.
- Workshop services include inspection, maintenance, repair, overhaul, and painting.
- Genuine, aftermarket, and used parts are available, with detailed quotes provided line by line.
- A complete inspection identifies worn parts that should be replaced before they fail.
- New machines have a 24-month manufacturer’s warranty. Failures caused by improper use are not covered.
- The buyer checks the service log when the machine is sold.
- Engine oils are matched to the machine, from Motorex, Motul, and FUCHS.
- Soot accumulates in the particulate filter, which must be cleaned at the workshop.
- Worn parts can be replaced preventively.
- Engine remapping is available at the dealership.
- The shop has a Maintenance category containing oils, coolants, greases, and hand tools from RMS.
- Wear and breakdowns are reworked so that a new machine lasts, while a mistreated machine fails.
- Warranty, parts quality, quotes, greasing, starting, and harvesting components are reworked.
- Workers take care of the machine, including with Courseplay and AutoDrive.
- Supports 27 languages.
Compatible with:
- Courseplay
- AutoDrive
- Realistic Harvesting

Changelog
- BETA 7
Changelog 1.0.0.0-beta.2:- Added required tractor power to implement info cards in the equipment menu.
- Added engine remapping (tuning) at the dealership.
- Added a “Maintenance” category to the shop, featuring oils, coolants, greases, and hand tools from RMS.
- Added engine oils specific to each machine, sourced from Motorex, Motul, and FUCHS. Engines equipped with AdBlue or a particulate filter (DPF) require specific oil. Using the wrong type will cause the oil change interval to be cut by up to half.
- Added particulate filter (DPF) ash accumulation. Regeneration cycles will occur with increasing frequency until the filter becomes full, restricting engine performance and requiring it to be cleaned in the workshop.
- Added the option for preventive replacement of worn parts identified during the most recent full inspection.
- Overhauled the wear and breakdown system. New machines rarely break down, whereas older or poorly maintained ones do so much more frequently. Overheating, holding the starter for too long, or over-angling a PTO shaft can cause components to fail.
- Overhauled low-fluid-level mechanics. If levels fall below the “MIN” mark, the pump may draw in air when operating on slopes. The oil warning light will flash, and components such as bearings or pumps will sustain damage.
- Pre-shift inspection correctly identifies low fluid levels and no longer confuses the air filter with the radiator.
- Warranty overhaul: covered breakdowns are repaired to a “standard” level using original parts. Damage caused by misuse, or the use of aftermarket or second-hand parts, is excluded, with the reason specified in the repair estimate.
- Parts quality overhaul: information cards display the wear, origin, and factory warranty for used parts. Low-cost maintenance may result in the installation of a defective filter.
- Repair method overhaul: “Standard” repairs replace the failed component and any collateral damage. “In-depth” repairs go further by overhauling the engine or cylinder head, including surrounding worn components. “Temporary” (field-expedient) repairs do not involve replacing any parts.
- Repair estimate overhaul: a consistent, detailed estimate format is used across all workshop pages, covering labor, parts, warranty status, and worn components identified during the latest inspection.
- Lubrication overhaul: only proper, thorough lubrication counts. Automated greasing systems are tracked via fleet alerts. Specific equipment, such as self-propelled forage harvesters and shredders, MacDon cutterbars, and onion planters, now requires active lubrication. Flatbed trailers are no longer greased using the same protocols as balers.
- Starting system overhaul: a dead battery can be jump-started using a loader’s jump-start function or jumper cables. In multiplayer, other players can hear the sound of a difficult engine start.
- Battery cart overhaul: the cart now remains stationary using its own brakes, and boarding it while using certain driving-related mods no longer triggers errors.
- Self-propelled harvester header overhaul: wear is now proportional to the volume of crop processed. Overloading triggers a warning light and slows down AI workers. A broken shredder no longer halts the harvesting process. The “Realistic Harvesting” mod is now fully integrated.
- Workshop accounting improvements: the summary now lists all maintenance performed, including full overhauls.
- An action that is cancelled no longer counts as having been completed.
- Fixed an issue where a machine left with its engine running would shut off automatically when the player moved too far away.
- Fixed an issue where AI workers and Courseplay would continue to push against an obstacle. They will now stop after 20 seconds of failing to move forward and be flagged as “blocked”.
- Fixed an issue where the engine temperature would spike upon re-entering a running machine when using certain dashboard mods.
- Removed the ability to queue multiple tasks at the workshop. Repairs or overdue maintenance are now determined based on the results of the service performed.
