134.1 cu in
Displacement Liters:
2.2 L
Horsepower:
Specific HP not provided, but typically in the 50-55 HP range for this model designation.
Torque:
Specific torque not provided, but turbocharged diesel engines offer good low-end torque for pulling power.
Injection Type:
Likely direct injection, common for modern diesel engines; specific details would be in the manual.
Transmission Type:
Likely a manual transmission with a synchronized gearbox, possibly with a shuttle shift option for forward/reverse. Specific type (e.g., HST, 16x16, etc.) would be detailed in the manual.
Optional Features:
Potential for Hydrostatic Transmission (HST) or different gear ratio options depending on specific sub-model or regional configuration.
Clutch:
Wet multi-disc clutch (common in tractors for durability, especially with PTO engagement) or dry single-disc clutch. Manual will specify.
Gear Selection:
Manual gear shifting with lever controls. PTO (Power Take-Off) speed selection will also be covered.
Length:
Specific dimensions not provided, but typical for a compact utility tractor in this HP class.
Width:
Specific dimensions not provided, but designed for maneuverability in agricultural and landscaping settings.
Height:
Specific dimensions not provided, likely to the top of the ROPS (Roll-Over Protective Structure) or cabin if equipped.
Operating Weight:
Specific weight not provided, but expected to be in the 3,000-5,000 lb range, depending on configuration and fluid levels.
Rops Certification:
Likely equipped with a certified ROPS for operator safety. Manual will confirm standards.
Braking System:
Mechanical or hydraulic wet disc brakes for reliable stopping power, detailed in the brake section.
Seatbelt:
Standard on ROPS-equipped tractors, with specific instructions for inspection and maintenance.
Operator Presence System:
Likely features an operator presence system to disengage PTO and transmission if the operator leaves the seat.
Radio Availability:
Optional on some configurations, typically a basic AM/FM/Weatherband radio. This manual focuses on mechanical and electrical systems, not infotainment features.
Traction Control:
N/A (Tractors of this class do not typically feature electronic driver assistance systems like those found in passenger vehicles.)
Bluetooth:
N/A (Not a standard feature on tractors of this vintage/class.)
Engine Oil Change:
Typically every 200-250 operating hours or annually, whichever comes first. Specifics in manual.
Hydraulic Fluid Change:
Typically every 500-1000 operating hours or annually. Manual will provide exact interval and procedure.
Air Filter Replacement:
Based on operating conditions, often checked daily and replaced as needed or at a scheduled interval (e.g., 250 hours).
Engine Oil Type:
API CJ-4 or higher, SAE 15W-40 (or as specified by Daedong for specific climate conditions). Consult manual for exact OEM specification.
Hydraulic Transmission Fluid:
KIOTI Genuine Hydraulic Oil, or a high-quality universal tractor transmission fluid (UTTO) meeting specific viscosity and performance standards. Manual is critical for this.
Coolant Type:
Ethylene Glycol based permanent antifreeze/coolant, typically a 50/50 mix with distilled water. Manual will specify concentration and type.
