Engine
The Kubota GB150 is equipped with a 0.9L 3-cylinder Kubota diesel engine, giving it more torque and power than the smaller 0.7L GB models.
| Item | Details |
|---|---|
| Engine manufacturer | Kubota |
| Engine type | 4-stroke, liquid-cooled diesel |
| Cylinders | 3 cylinders |
| Displacement | 0.9 L class (approx. 900 cc) |
| Engine power | 14.8 hp (11.0 kW) |
| Aspiration | Naturally aspirated |
| Fuel type | Diesel |
| Fuel tank capacity | 3.4 gal (12.9 L) |
| Cooling system | Liquid-cooled |
| Starting system | Electric start |
The 0.9L diesel provides stronger low-end torque, which is useful when operating rotary tillers, mowers or soil-working implements in heavier conditions.
Transmission
The GB150 uses a 6-speed gear transmission that is simple and durable.
It offers enough speed choices for tillage, mowing, and slow manoeuvring.
| Item | Details |
|---|---|
| Transmission type | Gear drive |
| Number of gears | 6-speed gear (forward/reverse combination) |
| Clutch | Dry single-plate (typical for this class) |
| Drive system | 4WD (Four-wheel drive) |
The mechanical gear transmission is easy to maintain and is well suited to areas where simple, reliable systems are preferred over complex electronics.
PTO (Power Take-Off) and Hitch
Like other GB models, the Kubota GB150 is equipped with a rear PTO and Category 0 three-point hitch, allowing it to work with a wide range of small implements.
Rear PTO
| Item | Details |
|---|---|
| Rear PTO type | 540 / 1000 rpm |
| PTO shaft size | 1.375″ |
3-Point Hitch
| Item | Details |
|---|---|
| Rear hitch type | Category 0 |
| Hitch control | Position control |
The position control system allows the operator to set and maintain implement height accurately, which is important for uniform tillage depth and clean mowing.
Dimensions & Tires
The GB150 shares the same compact wheelbase as other GB models, but with slightly higher weight due to the larger 0.9L engine.
| Item | Details |
|---|---|
| Wheelbase | 50 in (127 cm) |
| Weight | 1,246 lbs (565 kg) |
| Front tire | 5-12 |
| Rear tire | 8-16 |
This size makes the GB150 very suitable for:
-
Narrow orchard rows
-
Greenhouse paths
-
Tight yard spaces
At the same time, its modest weight helps reduce soil compaction, while 4WD provides good traction in soft or wet fields.
Electrical System
| Item | Details |
|---|---|
| Ground | Electric (negative ground) |
| Battery | 12-volt battery |
The standard 12V electrical system supports lights, instruments and reliable engine starting, and replacement parts are widely available.
