Depth:
Comprehensive workshop-level detail, suitable for qualified mechanics and experienced DIY users. Covers everything from basic adjustments to complete engine and transmission rebuilds.
Engine Model:
Likely a Kubota D700 or similar 2- or 3-cylinder diesel engine (specific model depends on exact B1550 sub-variant).
Engine Type:
Vertical, water-cooled, 4-stroke diesel
Displacement:
Typically around 1.0-1.5 liters (e.g., 702cc for D700) - check specific model variant.
Horsepower:
Approximate engine horsepower typically in the 15-20 HP range (gross) - check PTO horsepower for actual power output.
Torque:
Torque figures vary but provide strong low-end grunt for tractor applications.
Injection System:
Indirect injection (usually via rotary pump or distributor type injection pump).
Transmission Type:
Likely a synchronized constant mesh manual transmission with multiple forward and reverse gears (e.g., 8F/4R or similar).
Transmission Options:
Some variants might have offered a hydrostatic transmission (HST) as an option, providing infinite speed adjustment.
Gear Selection:
Manual gear levers for transmission and range selection (e.g., High/Low).
Pto Speed:
Standard PTO speeds (e.g., 540 RPM) for powering implements.
Overall Length:
Varies by configuration, typically around 2.5-3 meters without attachments.
Overall Width:
Varies by tire size and configuration, often around 1.2-1.5 meters.
Wheelbase:
Typically around 1.5-1.7 meters.
Operating Weight:
Approximately 800-1100 kg without ballast or attachments.
Lift Capacity:
Three-point hitch lift capacity would be specified in the manual, typically in the hundreds of kilograms.
Rollover Protection:
ROPS (Roll-Over Protective Structure) is standard or optional, often a foldable two-post ROPS. Seatbelts are essential.
Braking System:
Mechanical braking system, often internal expanding shoe brakes or disc brakes on rear axles.
Parking Brake:
Independent parking brake mechanism.
Lighting:
Headlights, taillights, brake lights, and indicator lights for road use (if equipped).
Engine Oil Change:
Typically every 100-200 operating hours or annually, whichever comes first.
Oil Filter Replacement:
At every engine oil change.
Air Filter Cleaning:
Regular checks (e.g., daily or weekly depending on dust conditions), cleaning or replacement as needed.
Fuel Filter Replacement:
Typically every 200-400 operating hours or annually.
Hydraulic Fluid Change:
Typically every 200-400 operating hours or annually.
Engine Oil Type:
API Service Category CD or CE or higher, SAE 10W-30 or 15W-40 diesel engine oil (check manual for specific viscosity based on ambient temperature).
Engine Oil Capacity:
Approximately 3.5 - 4.5 liters (check manual).
Hydraulic Fluid Type:
Kubota UDT Fluid (Universal Tractor Transmission Oil) or equivalent with good anti-wear and cold weather performance. ISO VG 32 or ISO VG 46 hydraulic oil may be specified for certain components.
Transmission Fluid Type:
Refer to manual for specific transmission lubricant. Often shares hydraulic fluid if a shared reservoir is used.
Coolant Type:
Ethylene glycol based antifreeze mixture (50/50 water/antifreeze) for freeze and corrosion protection.
Common Wear Items:
Brake pads/shoes, clutch wear, hydraulic seals and hoses, PTO clutch, mower deck bearings, and front axle kingpins can be wear items over time.
Electrical Connections:
Corrosion on electrical connectors or starter/alternator issues can occur with age and exposure.
Hydraulic Leaks:
Hose or seal degradation can lead to hydraulic fluid leaks, particularly around cylinders and pump connections.
Manufacturer:
Kubota Corporation, a Japanese company with a long history of producing agricultural machinery, construction equipment, and engines since 1890.
Series Positioning:
The B-Series represents Kubota's line of compact, versatile tractors, designed for ease of operation and a broad range of applications.
Production Period:
The B1550 was part of Kubota's B series that saw significant development through the late 1980s and into the 1990s, but specific production years for the B1550 variant should be confirmed.
