Depth Of Coverage:
Comprehensive. Covers everything from basic maintenance to complete engine and transmission rebuilds, including detailed troubleshooting and diagnostic data.
Engine Manufacturer Type:
Likely diesel engine (common for Iseki tractors of this era and size), specific model will vary by exact tractor variant and market.
Displacement Range:
Typically 1.0L - 1.5L for this class of tractor, providing adequate power for mowing and light work.
Horsepower Range:
Estimated 17 HP for SGR17 and 19 HP for SGR19, indicating engine displacement and intended application.
Injection Type:
Likely direct injection or indirect injection, depending on engine model.
Cooling Method:
Liquid-cooled, utilizing a radiator, water pump, and thermostat.
Oil Type Specification:
Refer to manual for specific diesel engine oil API classification (e.g., API CJ-4, CK-4) and viscosity grade (e.g., SAE 15W-40, 10W-30).
Ignition Type:
Glow plugs for cold starting (diesel), no spark plugs.
Transmission Type:
Hydrostatic Transmission (HST) is highly probable for this model, offering infinite speed variation and ease of operation.
Optional Transmissions:
While less common for this size, a gear transmission might be an option on some variants, but HST is the defining feature for ease of use.
Transmission Control:
Foot pedal control for forward and reverse motion, often with a high/low range selector.
Transmission Fluid Type:
Likely Iseki specific hydraulic fluid or a suitable universal tractor transmission fluid (UTTF) / gear oil. Manual will specify exact type and viscosity.
Overall Length:
Varies by configuration, but typically in the range of 2.5-3.0 meters (approx. 98-118 inches).
Overall Width:
Varies by mower deck size, but base tractor width typically around 1.2-1.5 meters (approx. 47-59 inches).
Operating Weight:
Estimated 600-800 kg (approx. 1300-1750 lbs), depending on configuration and attachments.
Safety Features Design:
ROPS (Roll Over Protection Structure) likely standard or optional, seatbelt, safety interlocks (e.g., PTO disengages if operator leaves seat, mower deck disengages when reversing).
Operator Presence System:
System that requires operator to be seated for mower or PTO to engage and remain engaged.
Illumination:
Headlights and taillights for visibility.
Engine Oil Change Interval:
Typically every 50-100 operating hours, or annually, whichever comes first. Refer to manual for exact interval and conditions.
Air Filter Replacement:
Inspect at frequent intervals, replace as needed based on operating conditions (dusty environments require more frequent checks/changes).
Fuel Filter Replacement:
Typically annually or every 200-300 operating hours, depending on fuel quality. Crucial for diesel engine longevity.
Hydraulic Fluid Change:
Refer to manual; often around 200-400 operating hours, or when fluid appears degraded.
Engine Coolant:
Ethylene glycol based antifreeze, mixed with distilled water. Refer to manual for correct type and ratio (e.g., 50/50 mix).
Grease Type:
General purpose lithium-based grease for lubrication points.
Common Wear Items:
Mower deck belts, spindle bearings, PTO clutch wear, hydraulic pump seals, starter brushes, battery terminals due to constant use.
Fuel System Maintenance:
Regular fuel filter changes and keeping fuel tanks clean are critical to prevent injector clogging or fuel pump issues in diesel engines.
Hydrostatic Transmission Care:
Regular fluid and filter changes are vital to the longevity of the HST unit. Avoid over-exerting the tractor beyond its intended capacity.
Iseki Legacy:
Iseki is a Japanese manufacturer with a long history in agricultural and compact tractor production, known for reliable and durable machinery.
Sgr Series Purpose:
The SGR series represents Iseki's offering in the homeowner and light commercial property maintenance segment, focusing on versatility and ease of use for tasks like mowing, tilling, and light towing.
Production Period Estimation:
