โ๏ธ Engine Specifications
Engine Families:
Likely Same 1000 Series (e.g., Same Deutz-Fahr 1000 Series engines, with specific configurations for each HP variant).
Horsepower Range:
Approx. 55 HP (Dorado 55) to 85 HP (Dorado 85), with intermediate models likely featuring tuned power outputs.
Torque Specifications:
Specific torque figures for each model variant would be detailed in the manual, crucial for engine assembly and component tightening.
Injection Type:
Likely direct injection, possibly with mechanical or electronic control depending on the specific year of manufacture within the Dorado range.
Type:
Liquid-cooled (water-cooled).
Oil Type:
Specific SAE viscosity grades (e.g., SAE 15W-40, SAE 10W-30) for different ambient temperatures would be detailed.
Features:
Could include electronic control units (ECUs) for later models, affecting fuel injection timing, emissions control.
Type:
Likely a fully synchronized mechanical gearbox with multiple speed ranges (e.g., 12 forward, 12 reverse or similar configurations).
Features:
Possibility of creeper gears, shuttle shift, or other transmission options depending on the specific Dorado variant.
Power Take Off Pto:
Standard PTO speeds (e.g., 540, 540E, 1000 RPM) would be covered, along with engagement and maintenance.
Transmission Oil Type:
Specific GL-4 or GL-5 rated gear oil grades, or UTTO (Universal Tractor Transmission Oil) specifications.
Wheelbase:
Variable by model variant, but typical for compact utility tractors in this class.
Overall Length:
Specific dimensions would be provided in the manual.
Overall Width:
Specific dimensions would be provided in the manual.
Operating Weight:
Varies by model and configuration, typically ranging from 2000-3000 kg for this class of tractor.
Max Gross Weight:
Specific figures for maximum permissible weight would be included.
Rollover Protection:
Likely includes options for ROPS (Roll-Over Protective Structure) or enclosed cabs meeting safety standards.
Braking System:
Hydraulic wet disc brakes, offering reliable stopping power.
Seatbelts:
Likely equipped, especially on models with cabs.
Lighting:
Headlights, taillights, and work lights for safe operation.
Engine Oil And Filter:
Typically 250-500 operating hours, or annually, depending on operating conditions and specific engine model.
Transmission Hydraulic Oil And Filter:
Usually 1000-1200 operating hours, or bi-annually.
Air Filter Element:
Check regularly, replace as needed based on dust conditions (e.g., every 250 hours or annually).
Fuel Filter:
Replace at recommended intervals (e.g., every 500 hours) or if fuel system issues arise.
Engine Oil:
API CG-4 or higher, SAE 15W-40 recommended for most ambient temperatures. Refer to manual for specific temperature charts.
Coolant:
Ethylene glycol-based antifreeze mixture, typically a 50/50 blend with deionized water.
Hydraulic Transmission Fluid:
UTTO (Universal Tractor Transmission Oil) meeting specifications like AGMA 9005-E2 or equivalent.
Brake Fluid:
DOT 3 or DOT 4 brake fluid, depending on system requirements.
Hydraulic System:
Potential for leaks at seals and hoses, especially with age. Filter contamination can also affect performance.
Electrical Connections:
Corrosion or loose connections in wiring harness can lead to intermittent issues, particularly in damp environments.
Transmission Shifting:
Synchronization issues or stiffness in shifting may occur if lubrication is inadequate or components wear.
Engine Starting:
Glow plug functionality and battery condition are critical for reliable cold starts.
