Iseki & Co., Ltd. was founded in 1926 and is based in Matsuyama, Ehime, Japan. The company built its reputation manufacturing compact agricultural machinery for the Japanese market before expanding into equipment sold worldwide.

Iseki is known for compact tractors, combine harvesters, riding mowers and zero-turn mowers, many of them powered by the company's own three-cylinder diesel engines. Iseki-built compact tractors have also been sold under other manufacturers' brand names, extending the reach of its engineering beyond its own badge.

The manuals available here cover Iseki's E3221 and E393 engines along with lawnmower, zero-turn mower and compact tractor service content. Topics include engine rebuild procedures, transmission and drivetrain service, electrical system troubleshooting, torque specifications and scheduled maintenance intervals.

These manuals are useful for DIY equipment owners, independent small-engine and tractor repair shops, and restorers working on older Iseki-powered machines, giving them the detailed factory procedures needed to keep this equipment running well. Because compact tractors and mowers see hard seasonal use, the manuals also cover hydraulic systems, PTO service and cooling system upkeep, giving owners and technicians a complete reference for keeping Iseki-powered equipment running through planting, mowing and harvest seasons. They also include troubleshooting steps for starting, charging and fuel delivery issues, helping owners resolve common problems without guesswork. Restorers working on older machines will also find the historical model context useful when sourcing parts and planning a rebuild.
