Clearances And Tolerances:
Provides essential factory specifications for component clearances and operating tolerances.
Engine Type:
Typically a diesel engine, configuration depends on specific SGR model variant (e.g., 3-cylinder diesel).
Displacement:
Specific displacement to be detailed in the manual, likely in the 1.1L to 1.7L range for this class of tractor.
Horsepower:
Approximate horsepower typically ranges from 17 HP for the SGR17 to 19 HP for the SGR19.
Injection System:
Direct injection, common for Iseki diesel engines.
Cooling Type:
Liquid-cooled
Oil Type:
Specified in the manual, likely a multi-grade diesel engine oil (e.g., SAE 10W-30 or 15W-40).
Oil Capacity:
Specific capacity to be detailed in the manual, typically around 4-6 liters.
Instrument Panel:
Basic instrument cluster typically includes fuel gauge, temperature gauge, hour meter, and warning lights for oil pressure, battery, and engine.
Operator Presence System:
Features an operator presence control system that stops the engine and PTO when the operator leaves the seat.
Cruise Control:
Some higher-spec models may offer cruise control functionality for consistent mowing speeds.
Engine Oil Change:
Typically every 50-100 operating hours or annually, whichever comes first (specifics in manual).
Air Filter Replacement:
Recommended at specified intervals or when visibly dirty. Check manual for specific hours/conditions.
Fuel Filter Replacement:
Crucial for diesel engines; recommended at intervals specified by Iseki, typically annually or every 200 hours.
Hydraulic Fluid Filter:
Replace per manufacturer's recommendation, often tied to engine oil service intervals or specific operating hours.
Engine Oil Viscosity:
Refer to the manual for precise viscosity grade based on ambient temperature. Common grades: 10W-30, 15W-40.
Hydraulic Fluid Type:
Refer to manual for exact Iseki specification or industry equivalent (e.g., ISO VG 46, Universal Tractor Transmission Fluid (UTTF) might be specified).
Common Wear Items:
Mower deck belts, spindle bearings, hydrostatic transmission fluid contamination, and diesel injector clogging are common wear-related issues.
Starting Problems:
Common causes include battery issues, fuel system blockages (water in fuel, clogged filters), glow plug issues, or starter motor problems. Manual guides diagnosis.
Hydrostatic Performance Loss:
Can be caused by low hydraulic fluid, contaminated fluid, worn hydraulic pump/motor, or leaks. Manual provides testing procedures.
