Typically rated for towing moderate loads, specific rating needed from service manual
Rops Certification:
Standard ROPS (Roll-Over Protective Structure) for operator safety
Braking System:
Wet disc brakes, mechanically actuated
Differential Lock:
Foot-pedal operated rear differential lock for improved traction
Seatbelt:
Likely equipped with a retractable seatbelt for ROPS-equipped tractors
Lighting:
Headlights, taillights, and work lights may be standard or optional
Operator Interface:
Basic dashboard with essential gauges (engine temperature, oil pressure, fuel level, tachometer, hour meter). No modern infotainment systems.
Traction Control:
Limited to mechanical differential lock. No electronic traction control systems.
Connectivity Features:
No modern connectivity features like Bluetooth, Wi-Fi, or USB ports.
Engine Oil Change:
Typically every 100-250 operating hours or annually, depending on service severity. Specific interval to be confirmed in service manual.
Hydraulic Fluid Change:
Generally every 200-400 operating hours or annually. Filter replacement is also crucial.
Air Filter Replacement:
Check and clean at frequent intervals, replace as needed based on operating conditions (e.g., dusty environments).
Engine Oil Type:
API Service Category CD, CE, or CF, SAE 10W-30 or 15W-40 recommended (refer to manual for precise specification and ambient temperature suitability).
Hydraulic Fluid Type:
Kubota Super UDT, or equivalent UTF (Universal Tractor Transmission Fluid) meeting ISO 11158 Category HV or TDH. Specific Kubota part number is recommended.
Coolant Type:
Ethylene Glycol based permanent antifreeze (50/50 mix with distilled water) meeting ASTM D3306 or similar standards.
Common Wear Items:
Clutch discs (Synchro Shuttle), hydraulic pump seals, PTO clutch packs, front axle pivot bushings, and radiator hoses are common wear items on tractors of this age.
Potential Electrical Issues:
Wiring harness degradation, corrosion on electrical connectors, and failure of starter/alternator can occur with age.
Importance Of Filters:
Crucial to maintain engine oil, hydraulic, and fuel filters as per schedule to prevent premature component wear and system failure.
Grease Points:
Numerous grease points on steering linkage, PTO shaft, lift arms, and front axle pivots require regular greasing.
Manufacturer Legacy:
Kubota is a highly respected Japanese manufacturer with a long history in industrial and agricultural machinery, known for durability and reliability.
L Series Placement:
The L-Series is Kubota's popular line of compact tractors, often representing a balance of power, features, and value. The L3450DT would fit within a mid-range of this series during its production years.
Production Years:
The L3450DT was primarily produced in the late 1980s and early 1990s. Specific production year range: circa 1986-1993.
