The technical specifications of the Kubota B1-14, B1-15, B1-16, and B1-17 are largely identical — they share the chassis, transmission, and hydraulics. The difference lies in the engine: the B1-14 and B1-15 have the Kubota D850, while the B1-16 and B1-17 have the larger D950. The figures below come directly from the original manuals.
Suitable for the entire series: B1-14, B1-15, B1-16, and B1-17, including the Zen-noh rebadges ZB1-14 through ZB1-17.
| Specification | B1-14 / B1-15 | B1-16 / B1-17 |
|---|---|---|
| Engine type | Kubota D850 | Kubota D950 |
| Design | water-cooled 4-stroke 3-cylinder diesel engine | water-cooled 4-stroke 3-cylinder diesel engine |
| Displacement | 855 cc | 927 cc |
| Bore × stroke | 72 × 70 mm | 75 × 70 mm |
| Maximum power | 14.5 hp (B1-14) / 15.5 hp (B1-15) at 2600 rpm | 16.5 hp (B1-16) / 17.5 hp (B1-17) at 2600 rpm |
| Fuel | diesel; tank capacity 17 L | diesel; tank capacity 17 L |
| Starting | electric starter motor (12 V, 0.8 kW), automatic glow plug preheating | electric starter motor (12 V, 0.8 kW), automatic glow plug preheating |
| Battery | 12 V, 45 Ah | 12 V, 45 Ah |
Note the most important practical difference: because the bore differs (72 versus 75 mm), the head gasket, cylinder head, and pistons are not interchangeable between the D850 pair (B1-14/15) and the D950 pair (B1-16/17). The stroke is the same, however. So when ordering engine parts, it's essential to know whether you have a D850 or a D950.
These measurements and weights come from the manual and apply without a mounted tiller. Two-wheel drive (2WD) is the baseline here; four-wheel drive (4WD/D/DB) is somewhat taller, has a different front track width, and is heavier (4WD weight listed separately). The M and MA versions weigh approximately 15 kg more.
| Specification | B1-14 | B1-15 | B1-16 | B1-17 |
|---|---|---|---|---|
| Length (without tiller) | 2150 mm | 2190 mm | 2320 mm | 2340 mm |
| Width (narrowest setting) | 1055 mm (810) | 1055 mm (810) | 1150 mm (910) | 1150 mm (910) |
| Height (2WD) | 1235 mm | 1245 mm | 1235 mm | 1240 mm |
| Wheelbase | 1240 mm | 1245 mm | 1355 mm | 1355 mm |
| Ground clearance (2WD) | 285 mm | 310 mm | 305 mm | 305 mm |
| Weight 2WD (without tiller) | 545 kg | 560 kg | 645 kg | 650 kg |
| Weight 4WD (without tiller) | 550 kg | 570 kg | 690 kg | 695 kg |
| Min. turning radius | 1.65 m | 1.65 m | 1.75 m | 1.79 m |
| Front tires (2WD) | 4.50-10 | 4.50-10 | 4.00-12 | 4.00-12 |
| Rear tires | 8-16 | 8-18 | 8.3-20 | 8.3-22 |
The rear track width is adjustable (from approximately 810 mm). On the 4WD versions, the front tires are 5.00-12 and the front ground clearance is somewhat lower due to the driven front axle.
The drivetrain is a non-synchronized gear transmission (selective sliding-mesh) with six forward and two reverse gears. The clutch is a dry single-plate type; the steering operates via a ball screw. The rear PTO has three speeds, rotates clockwise when viewed from the rear, and is driven via a 6-spline shaft of 35 mm. The PTO shaft is positioned at approximately 490 mm height (2WD) or 525 mm (4WD) on the B1-14/15, and approximately 435 mm (2WD) or 460 mm (4WD) on the B1-16/17.
These capacities come directly from the manual and are the same for all four models:
| System | Capacity |
|---|---|
| Fuel tank | 17 L |
| Coolant | 3.4 L |
| Engine oil | 3.4 L (up to upper mark on dipstick) |
| Transmission/hydraulic oil | 12 L |
| Steering housing | ±0.2 L |
| Front differential (4WD) | 1.5 L (D) / 2.5 L (DB) |
