Engine Manufacturer And Series:
David Brown (likely fitted with a Perkins or similar engine common to the era, but specific to David Brown 1690 series implementation).
Engine Type:
Typically a naturally aspirated diesel engine.
Horsepower Rating:
Approximately 95-100 PTO horsepower (exact rating varies by specific configuration and engine tune).
Torque Output:
Details would be found within the manual, specific to the fitted engine variant.
Fuel Injection Type:
Mechanical direct injection (e.g., Bosch or CAV).
Cooling Type:
Water-cooled
Oil Type:
Refer to manual for specific API or ACEA specifications and SAE viscosity grades (e.g., SAE 15W-30, SAE 30).
Transmission Type:
David Brown Synchromesh Transmission (typically 12-speed forward and 4-speed reverse or similar options).
Optional Features:
Power take-off (PTO) options, potentially creeper gears or enhanced PTO speeds depending on configuration.
Gear Selection:
Manual gear shifting via main gear lever and range selector.
Clutch Type:
Dual-stage clutch (for independent PTO engagement if applicable) or single-stage clutch.
Transmission Oil Type:
Refer to manual for specific GL-4 or GL-5 gear oil specifications and viscosity grades.
Overall Length:
Varies by configuration; detailed specifications would be in the manual.
Overall Width:
Varies by configuration; detailed specifications would be in the manual.
Wheelbase:
Varies by configuration; detailed specifications would be in the manual.
Operating Weight:
Typically in the range of 4500-5500 kg (unballasted), depending on configuration. Precise weights are in the manual.
Rollover Protection Standard:
While not a statutory rating like modern vehicles, the manual would cover ROPS (Rollover Protective Structure) installation and maintenance if factory-fitted or aftermarket.
Braking System Effectiveness:
Manual provides procedures for brake adjustment and maintenance for optimal safety.
Seatbelts:
Manual would specify seatbelt installation and maintenance if equipped.
Infotainment System:
Basic for its era; typically limited to an AM/FM radio (if factory-fitted), with speaker provisions.
Driver Assistance Features:
None typical for modern standards. Focus is on mechanical and hydraulic control systems.
Connectivity Features:
N/A
Dashboard Instruments:
Includes tachometer, engine temperature gauge, oil pressure gauge, fuel gauge, and warning lights for critical systems.
Engine Oil And Filter Change:
Typically 250 hours or annually, but the manual will specify exact intervals and conditions.
Transmission Oil Change:
Recommended at specific hour intervals (e.g., 1000 or 1500 hours), consult the manual for precise data.
Hydraulic Oil Change:
Refer to manual for specific intervals and filter replacement schedules.
Greasing Points:
Daily or weekly greasing of various pivot points and bearings as detailed in the manual.
Engine Oil Recommendation:
Refer to manual for specific API Service categories (e.g., CD, CE) and SAE viscosity grades.
Hydraulic Fluid Type:
Refer to manual for specifications (e.g., UTF - Universal Tractor Transmission Fluid, or specific hydraulic oil). Capacity would also be listed.
