Engine Model B6200Hst:
Kubota D600 Series (Typical 2-cylinder diesel)
Engine Model B7200Hst:
Kubota D750/D850 Series (Typical 3-cylinder diesel)
Estimated Horsepower B6200Hst:
Approx. 15-20 HP (Varies by specific configuration)
Estimated Horsepower B7200Hst:
Approx. 20-25 HP (Varies by specific configuration)
Injection Type:
Indirect injection (typical for this era)
Engine Cooling:
Liquid-cooled diesel engine.
Governor Type:
Mechanical governor for consistent engine speed.
Tractor Class:
Sub-Compact / Compact Tractor
Operating Weight Estimate:
Approx. 1200-1500 lbs (600-700 kg), depending on configuration.
Front Axle Weight Estimate:
Estimate based on typical distribution for this class of tractor.
Rear Axle Weight Estimate:
Estimate based on typical distribution for this class of tractor.
Engine Oil Change:
Typically every 50-100 operating hours or annually, depending on usage and oil type (refer to manual for specific Kubota recommendations).
Transmission Fluid Change:
Regular checks and changes recommended, often every 200-300 hours for HST fluid (refer to manual).
Air Filter Replacement:
As needed, based on operating conditions, or at recommended hourly intervals.
Hst Filter Replacement:
Crucial to replace the HST hydraulic filter during fluid changes as per manual recommendations.
Engine Oil Type:
API CD or CE classification diesel engine oil, SAE 10W-30 or 15W-40 (consult manual for exact specification and viscosity by temperature).
Hydraulic Fluid Type:
Kubota UDT fluid or equivalent (Universal Transmission Fluid) is often specified for HST systems and hydraulics (verify with manual).
Coolant Type:
Ethylene glycol-based antifreeze/coolant with water (50/50 mix recommended).
Transmission Fluid Capacity Estimate:
Approximately 3-4 gallons (11-15 liters) for the HST reservoir (verify with manual).
Differential Axle Fluid:
Gear oil, viscosity and type to be confirmed in manual, typically GL-4 or GL-5.
Transmission Fluid Viscosity:
Typically SAE 10W-30 or 80W-90 for transmission/hydraulic reservoir depending on specific Kubota recommendations.
Common Wear Items:
HST pump/motor wear, seal leaks, aging electrical connections, and linkage wear are common in older units.
Preventative Maintenance Focus:
Regular hydraulic fluid and filter changes are crucial for HST longevity. Monitoring for leaks is also important.
Hst Performance Degradation:
Can occur with age and lack of proper fluid maintenance, leading to reduced power or erratic speed control.
Cooling System Maintenance:
Regular flushing and refilling of coolant prevents overheating and corrosion.
