Mitsubishi GS16-GS25 transmission, brakes and steering
All models have the same drivetrain setup: a dry single-plate clutch, a mechanical gearbox with constant mesh plus sliding selection, and 8 forward and 8 reverse gears. The brakes are wet disc brakes, individually operable on the left and right and lockable for road transport. Steering is via hydrostatic power steering (orbitrol).
| Component | Specification |
|---|---|
| Clutch | Dry single plate |
| Brake | Wet disc brake, left/right |
| Steering | Hydrostatic power steering (orbitrol) |
| Gears | 8 forward / 8 reverse |
| Forward travel speed | approx. 0.8 – 14.5 km/h |
| Min. turning radius | 1.8 m (GS16-GS20) / 1.9 m (GS21-GS25) |
Mitsubishi GS16-GS25 tires and track width
Tire sizes increase with the model and equipment grade. Rear track is adjustable in two positions on most models.
| Model | Front tire | Rear tire | Wheelbase |
|---|---|---|---|
| GS16 | 6-12 / 5.00-12 | 8.3-20 / 8-18 | 1,380 mm |
| GS18 | 6.00-12 | 8.3-22 | 1,380 mm |
| GS20 | 6.00-12 | 8.3-22 | 1,380 mm |
| GS21 / GS21S | 6-14 / 5.00-12 | 8.3-24 / 8-16 | 1,380-1,450 mm |
| GS23 | 6-14 | 9.5-22 | 1,450 mm |

Mitsubishi GS16-GS25 PTO and lift system
The PTO is a JIS 35 shaft with multiple speeds. On the lighter models (GS16 to GS21) the PTO runs at 566, 816 or 1,310 rpm forward and 952 rpm reverse; on the GS23, GS25 and GS25S it's 589, 849 or 1,362 rpm forward and 990 rpm reverse. The three-point lift system is a category 0 (JIS 0) with position control; depending on the version, with automatic depth and tilt control.
| Component | Specification |
|---|---|
| PTO shaft | JIS 35 |
| PTO speeds (GS16-GS21) | 566 / 816 / 1,310 forward, 952 reverse |
| PTO speeds (GS23-GS25) | 589 / 849 / 1,362 forward, 990 reverse |
| Lift system | 3-point, category 0 (JIS 0) |
| Lift control | Position control (PAC/JAC/MAC versions) |
Product tip. Knowing the exact specs also tells you which parts fit. The engine parts are shared with the entire S3L/S3L2 family: the Filter set Mitsubishi GS series (SKU-100164), the starter motor 12 V / 1.6 kW (SKU-1290016) and the water pump (SKU-323) fit the GS16-GS25.
