Model Line:
Kubota M4900/M4900SU Series Tractors are typically equipped with Kubota's own diesel engines.
Engine Type:
Naturally Aspirated or Turbocharged Diesel (specific to model variant and year, likely a 3 or 4-cylinder direct injection diesel)
Displacement:
Typical for this class would be in the range of 1.8L to 2.4L (exact specification depends on specific engine variant, e.g., D1803, V2203, etc.)
Horsepower:
Around 45-50 PTO horsepower (exact rating varies by specific engine and model configuration)
Torque:
Specific torque figures would be detailed in the manual, crucial for power take-off and implement operation.
Fuel Injection:
Direct Injection, typically with a Bosch or similar in-line or rotary injection pump.
Oil Type:
API CE, CF, CG-4, or CH-4 rated diesel engine oil, viscosity grade typically 15W-40 or 10W-30 depending on ambient temperature (specific to manual).
Coolant Type:
Ethylene glycol based antifreeze/coolant with rust inhibitors. Typically a 50/50 mix with distilled water. (Exact specification in manual).
Transmission Type:
Commonly equipped with a synchronized main transmission with a range gear (e.g., 8 Forward / 4 Reverse or similar configuration) and an optional or integrated shuttle shift or hydraulic shuttle.
Transmission Features:
Some models may feature a Kubota Synchro Shuttle (KSS) or other power shuttle options for forward/reverse gear changes without clutch pedal use.
Pto Options:
Standard PTO is typically 540 RPM, often with an optional 540/1000 RPM PTO, and an independent PTO clutch engagement.
Transmission Fluid:
Kubota's own UDT (Universal Tractor Transmission Oil) or equivalent fluid is often specified for transmission, hydraulics, and differential/final drives. (Critical to verify specific grade in manual).
Wheelbase:
Varies by model (M4900 likely 75-80 inches, M4900SU typically shorter for maneuverability).
Operating Weight:
Approximately 3,500 - 4,500 lbs (without front loader, ballast, or attachments). Exact weight will vary based on configuration (e.g., M4900SU is often lighter).
Dashboard Features:
Basic analog gauges for engine RPM, temperature, fuel level, and hour meter. Warning lights for oil pressure, battery charging, and transmission temperature.
Operator Interface:
Mechanical clutch pedal, gear levers, PTO engagement lever, 3-point hitch controls (draft and position control levers), hydraulic remote valve controls (if equipped).
Attachment Interface:
Standard 540 RPM PTO, Category 1 three-point hitch for implements, hydraulic remotes for operating auxiliary equipment like front loaders or hydraulic cylinders.
Engine Oil Change:
Typically every 100-250 operating hours, or annually, whichever comes first (specific interval detailed in the manual).
Fuel Filter Replacement:
As per schedule, often coinciding with oil changes or every 250-500 hours, or when experiencing fuel system issues.
Air Filter Cleaning Replacement:
Check and clean every 50-100 hours, replace as needed based on operating conditions (dusty environments require more frequent checks).
Hydraulic Fluid:
Kubota UDT or equivalent ISO VG 46 hydraulic fluid (or as specified by the manual).
Transmission Fluid:
Kubota UDT or equivalent universal tractor transmission fluid.
Coolant Capacity:
Specific capacity for the M4900/M4900SU engine cooling system will be detailed in the manual, typically in the 6-8 liter range.
Common Wear Items:
Clutch wear, hydraulic pump output degradation over time, potential for injector pump calibration drift, PTO clutch wear on heavily used units.
Electrical Gremlins:
Wiring harness abrasion in high-vibration areas, starter/alternator reliability can be a concern on older units if not maintained.
Manufacturer:
Kubota Corporation is a Japanese company known for its diverse range of products, including tractors, construction equipment, and engines, with a strong reputation for reliability and quality in the agricultural sector.
Series Placement:
The M4900 series represents Kubota's compact to utility tractor range, designed for a variety of agricultural, landscaping, and property maintenance tasks. The 'SU' designation often indicates a 'Special Utility' or 'Shuttle' version, typically with a more compact wheelbase and enhanced maneuverability.
