⚙️ Engine Specifications

Engine Families Covered:

Likely includes variants of Case IH's own diesel engines (e.g., 4-cylinder diesel) and potentially gasoline engine options depending on specific tractor configurations.

Engine Displacement Range:

Typically in the 200-270 cubic inch range for these models, depending on specific engine option (e.g., 201 cu. in. for 730, 221 cu. in. for 830 diesel).

Horsepower Range:

Approximately 50-65 PTO horsepower, varying by engine and specific model designation.

Fuel Type:

Diesel and Gasoline (depending on specific tractor configuration)

Injection System:

Likely Roosa Master or Bosch inline injection pumps for diesel variants.

🔧 Transmission

Transmission Type:

Constant mesh spur-gear transmission with multiple speed options.

Gear Configurations:

Commonly offered with 6-speed or 8-speed forward gears and 2 reverse gears. Specific configurations like 'Powershift' (though less common on these exact models) or 'Vari-Speed' are not typically associated with the base 730/830 but variants might exist.

Power Take Off Pto:

Standard PTO (540 RPM) and potentially live PTO options.

Transmission Fluid Type:

Hydraulic Transmission Fluid (HTF) or equivalent agricultural tractor oil, e.g., Case IH Hy-Tran Ultra. Specific part numbers for filters and seals will be detailed in the manual.

📐 Dimensions

Wheelbase:

Approx. 80-85 inches (varies slightly)

Operating Weight:

Approx. 4,000 - 5,500 lbs (without ballast)

Drawbar Pull Capacity:

Designed for moderate draft loads, specific rating depends on configuration and ballast.

🛡️ Safety Features

Rollover Protection Structure Rops:

Original models typically did not include factory-installed ROPS. Aftermarket ROPS installation is common for safety.

Braking System:

Mechanical drum brakes acting on rear axle.

Operator Station Design:

Open operator station. Seat belt provision may vary by original configuration and aftermarket additions.

💡 Technology Features

Infotainment System:

N/A (Agricultural tractor of its era, focused on functionality).

Driver Assistance Features:

The 'EH' designation implies advanced (for its time) hydraulic controls, potentially including power steering assistance, rather than modern driver-assistance systems.

Connectivity Options:

N/A

🔧 Maintenance

Engine Oil Change Interval:

Typically every 100-200 operating hours, or annually. Specific recommendation based on engine oil type and operating conditions.

Transmission Fluid Change Interval:

Recommended every 500-1000 operating hours. Filter replacement at similar intervals or as indicated by hydraulic system performance.

Engine Oil Viscosity:

SAE 30 or 10W-30 diesel engine oil, depending on ambient temperature. API CD or equivalent rating.

Hydraulic Fluid Specification:

Case IH Hy-Tran Ultra or equivalent UTF (Universal Tractor Fluid). Specific part numbers for filters and seals are critical and will be in the manual.

Coolant Specification:

Ethylene glycol based antifreeze mixed with distilled water for a 50/50 ratio.
