| Specification | Value |
|---|---|
| General | |
| Brand | Yanmar |
| Model | RS24 |
| Series | Yanmar RS-serie |
| Build years | 1993-1999 |
| What to look for when buying | Inspection points, common issues and price guide View buying guide → |
| Engine type | 3TNE82-RZSN |
| Power | 24 hp (17.7 kW) @ 2600 rpm |
| Cylinders | 3 |
| Bore × stroke | 82 × 90 mm |
| Injection pump | Bosch-type, semi-throttle injectors |
| Fuel | Diesel; tank 30 l (cabin version 32 l) |
| Replace engine oil filter | First time after 50 hours, then every 300 hours (or every 2–3 oil changes) |
| Fuel filter/strainer cleaning — element replacement | Clean every 100 hours; replace element every 300 hours |
| Clean / replace air filter element | Normal: clean every 100 hours, replace every 1000 hours; dusty work: clean every 50 hours, replace every 400 hours; replace at least once a year |
| Check fuel lines and clamps | Every 50 hours; replace every 2 years |
| Radiator hoses and power steering hoses | Check daily; replace every 2 years |
| Engine oil filter | Spin-on cartridge |
| Fuel filter (element in strainer) | Element in glass/plastic housing |
| Air filter element | Dry paper element |
| Ignition switch or starter motor faulty | Test with a multimeter; have the starter motor overhauled or replaced. |
| Fuel and fuel tap | Fill the tank, set the tap to "O", bleed the system (tap open, full throttle, start). |
| Air in the fuel system | Bleed the system; then check lines and clamps for leaks. |
| Stop solenoid (fuel shut-off) | A known practical issue on this series: if the solenoid isn't energised, the pump receives no fuel and the engine won't start — or it cuts out during work. Check the plug and fuse, otherwise replace the solenoid. |
| Engine or governor fuse, relay | The RS has separate fuses for the electronic control system (including 15A) plus a main relay and an actuator relay — check and replace them one by one. |
| Drivetrain | |
| Forward speeds (3 settings) | 550 / 796 / 1270 rpm |
| Reverse speed (1 setting) | 665 rpm |
| Transmission oil (incl. hydraulics and power steering) | 25 liters |
| Check transmission oil (also hydraulic/steering oil) | Every 50 hours; change first time after 50 hours, then every 300 hours |
| Replace line filter (transmission oil filter) | First time after 50 hours, then every 300 hours |
| Clean oil strainer (screen) in the transmission | With every oil change (50/300/600 hours) |
| Lubricate (brake pedal shaft, clutch shaft, front axle center pin) | Every 50 hours, and always after working in wet land or mud |
| Clutch pedal play | 20 – 30 mm |
| Brake pedal play (left = right!) | 20 – 30 mm |
| Line filter (transmission/hydraulics) | Spin-on cartridge |
| Clutch pedal fully depressed? | The safety switch otherwise blocks the starter motor. From practical experience: worn or dirty contacts on this switch are a known cause of "it does absolutely nothing" — test the switch with a multimeter and replace if necessary. |
| Tipping trailer (with overrun brake) | 1.5 tonnes |
| Dimensions | |
| Length (to lower links) | 2970 mm |

| 3TNE84 | RS-270, RS-300, RS-330 |
| Small | RS-240, RS-270 |
| Large | RS-300, RS-330 |
| Check / change front axle oil | Check every 50 hours; change every 300 hours |
| Clean radiator screen and cooling fins | Every 50 hours (with straw/dust: every working day) |
| Check V-belt (cooling fan) | Every 50–100 hours; check new belt again after 50 hours |
| Check electrical wiring | Every 50 hours or once a year |
| Check steering ball joints and important bolts | Every 100 hours |
| Have valve clearance and injectors checked | Every 600 hours (workshop) |
| Steering wheel play | 20 – 50 mm |
| Front wheel toe-in | 0 – 5 mm (A−B ± 5 mm) |
| V-belt deflection | 10 – 15 mm under thumb pressure |
| Front wheel bolts | RS-240/270: 6.7–8.5 kgm · RS-300/330: 16–19.6 kgm |
| Rear wheel bolts | 16 – 19.6 kgm (all models) |
| Battery full and connected? | Top up fluid, charge; clean terminals, tighten and grease them. |
| Main fuse / fusible link | Replace the fuse (correct rating!); have a discoloured fusible link replaced. |
| Pre-glow | If the glow indicator doesn't light up (or the lamp stays off), check the fuse first. |
| Implement doesn't lift | Lowering speed valve closed → open it. Transmission oil level too low → top up. Line filter clogged or suction line drawing air → replace filter, check couplings, check O-rings. Then: pump or control valve (workshop). |
| Implement doesn't lower | Lowering speed valve closed → open it. Lift lever still in "lift" position → move lever down. Dirt in the control valve → workshop. |
| Lift doesn't respond to the toggle switch | Check the control fuse, switch contact or (for shuttle-linked functions) the back switch; make sure the height limiter isn't left in the "low" position. |
| Rotor doesn't lower / automatic function doesn't respond (UFO) | A known real-world case: the rotor cover sensor cable runs stiffly or gets stuck, blocking the depth automatic function. Solution: replace the cable and mount it in the old adjustment position. For reference, the same applies to the levelling control: a stuck or broken adjustment cable/UFO cable causes the implement to hang crooked — after replacement, re-level it. (Part numbers vary per version; verify by serial number.) |
| Rotor rises on its own + noise from the pressure relief valve when starting | The rear cover of the rotor is still locked in the raised position → lower the cover. |
| Rotary tiller | 150 – 170 cm |
| Flail mower | 135 – 150 cm |
| Plough | 1-furrow, light 2-furrow |
| Cultivator/combinator | 140 – 160 cm |
| Snow plough / sweeper | 140 – 150 cm |
| Pre-glow light (予熱) | Lights up after ignition is turned "on"; goes out automatically as soon as the engine is ready to start |
| Oil pressure light | Should go out after starting; if it lights up during operation → stop immediately and check the oil level |
| Charge light | Lights up during operation → check the alternator or V-belt |
| "Implement raised" light | Stays on as long as the lift is in the upper position — starting is only possible when this light is off |
| Water temperature gauge | If it rises → check the radiator screen, coolant and V-belt |
| Hour meter + tachometer | Basis for your maintenance schedule (50/100/300 hours) |
