Standard ethylene glycol based antifreeze (e.g., 50/50 mix with distilled water), specific ratio and type will be detailed in the manual.

🔧 Transmission

Transmission Type:

Likely a manual transmission with multiple gear ranges (e.g., 8-speed or 12-speed) and possibly a Hi-Lo splitter or synchronizer for smoother shifting.

Gear Configuration:

Constant mesh gears with sliding jaw clutches for speed changes and a reverse gear.

Optional Transmission:

Some variations might have offered a shuttle shift or different PTO configurations.

Pto:

Standard rear PTO, likely 540 RPM, potentially with an optional 1000 RPM or ground-speed PTO.

Clutch Type:

Single-stage dry clutch for main drive, and a separate clutch for PTO engagement.

Transmission Oil Type:

Likely a universal tractor transmission oil (UTTO) or SAE 80W-90 gear oil, depending on the specific drivetrain and hydraulic integration. Manual will specify exact API classification and viscosity grade.
