Realistic Mechanical Systems BETA 6

FS25 Mods | 8 Nov, 2026

Your machines are aging. Their maintenance matters.

Realistic Mechanical Systems adds true mechanical simulation to Farming Simulator 25: your driving, the work required and maintenance determine the reliability, performance and cost of each machine.

Version 1.0 beta 1 marks the end of the alpha. The major systems are in place, and they will continue to evolve during the beta with new features, balancing and fixes.
