Binding Type Binding: Not Applicable (Digital Download) Paper Type Paper Type: Not Applicable (Digital Download) ⚙️ Engine Specifications Primary Engine Manufacturer: Iseki (Likely, or rebadged engine) Configuration: Diesel (Typical for this class of tractor) Displacement: Varies by specific model (e.g., H152 likely 1.5L class, H174 likely 1.7L class). Specifics in manual. Horsepower: Varies by specific model (e.g., H152 around 15 HP, H174 around 17 HP). Specifics in manual. Performance Torque: Engine specific, detailed in the full service manual. Fuel System Type: Direct Injection Diesel (Common) 🔧 Transmission Standard Type: Hydrostatic Transmission (HST) Optional Type: Not applicable for models specified with Hydrostatic Supplement Features Control: Foot pedal control for forward and reverse speed adjustment. Gear Selection: Typically two-range hydrostatic (e.g., Hi/Lo) for optimal power delivery. Fluid Type: Specialized Hydrostatic Transmission Fluid (HSTF) or equivalent (refer to manual for exact specification, e.g., Iseki genuine fluid or a compatible SAE 10W-30 or 15W-40 API CG-4 rated oil depending on OEM recommendation). Fluid Capacity: Varies by specific hydrostatic unit, detailed in the manual. 📐 Dimensions Exterior Overall Length: Model dependent, typically in the range of 2.5-3 meters. Overall Width: Model dependent, typically around 1.2-1.5 meters. Wheelbase: Model dependent. Weights Operating Weight: Model dependent, typically 800-1200 kg. Towing Capacity: Model dependent, consult full manual or tractor specifications. 🛡️ Safety Features Ratings Rollover Protection: Optional ROPS (Roll Over Protection Structure) may be available, check tractor configuration. Active Features Parking Brake: Mechanical parking brake integrated into transmission. Passive Features Operator Presence System: Likely features an operator presence control that disengages the PTO and transmission when the operator leaves the seat. 💡 Technology Features Infotainment Dashboard Features: Basic instrumentation including fuel gauge, engine temperature, hour meter, and warning lights for oil pressure, battery, and charging system. Driver Assistance Cruise Control: Not a standard feature on this class of tractor. Connectivity Remote Monitoring: Not applicable. 🔧 Maintenance Service Intervals Hydrostatic Fluid Change: Typically every 250-500 hours or annually, refer to the main service manual for precise intervals. Hydrostatic Filter Replacement: Coinciding with fluid changes. Fluid Specifications Hydrostatic Fluid Specification: Refer to the specific tractor's main operator or service manual for the exact OEM recommended fluid grade and type. Common recommendations include Iseki genuine HST fluid, or high-quality agricultural hydraulic fluids meeting specific viscosity and additive packages (e.g., API GL-4, Caterpillar TO-4, or specified SAE viscosity grades). Hydraulic System Fluid: If the hydraulic system and hydrostatic transmission share fluid, the specification will be critical. Likely a universal tractor transmission fluid (UTTF) or dedicated hydraulic fluid. Known Issues Hydrostatic Wear: Common wear items include hydrostatic pump and motor components, seals, and internal valving. Proper fluid maintenance is key to longevity. Cooling System Efficiency: Ensuring the hydrostatic transmission cooling system (radiator, filters) is clean and functional is vital to prevent overheating and premature wear. Leakage: Seal failures can lead to hydraulic fluid leaks, which can degrade performance and cause damage if not addressed promptly. 📚 Vehicle History Brand Heritage Iseki Legacy: Iseki is a well-established Japanese manufacturer of agricultural machinery, known for quality and reliability in compact and sub-compact tractor segments. Model Evolution Bolens Partnership: Bolens was a popular American brand of outdoor power equipment, often rebadging or collaborating with manufacturers like Iseki for their tractor lines during certain periods. Production Production Period: Likely produced in the late 1990s to early 2000s, specific years vary by model variant. 🏆 Awards & Recognition Recognitions Brand Reputation: Iseki and Bolens...
