Fuel System Fuel Type: Diesel Injection System: Injection pump and injectors (details not primary focus of this manual). 🔧 Transmission Standard Transmission Type: Sliding Gear, constant mesh transmission Gear Speeds: 8 Forward speeds, 2 Reverse speeds Optional Overdrive Transmission: Not typically offered on standard B-275 models, focus is on PTO integration with standard gearbox. Features Pto Drive Source: Driven by a dedicated gear train within the transmission or rear axle housing, engaging via a clutch mechanism. Pto Gear Ratio: Standard 540 RPM PTO output at rated engine speed (approx. 1500-1800 RPM engine speed). 1000 RPM PTO option may exist on some variants but is not the primary focus here. Fluid Requirements Transmission Oil Type: IH Hytran or equivalent universal tractor transmission fluid (UTTO) meeting API GL-4 specifications for moderate-duty applications. Transmission Oil Capacity: Approximately 6-7 US gallons (23-26 Liters) for the combined transmission and hydraulic reservoir. Specific PTO oil requirements are detailed within the manual. 📐 Dimensions Exterior Wheelbase: Approximately 81.3 inches (2065 mm) Length: Approximately 128 inches (3251 mm) with drawbar Width: Varies by tread setting, typically around 65-75 inches (1651-1905 mm) Weights Operating Weight: Approximately 4,500 - 5,000 lbs (2041 - 2268 kg) Pto Weight Consideration: Manual focuses on the internal components and their impact on PTO operation, not overall tractor weight. 🛡️ Safety Features Ratings Safety Standards: Operated according to general agricultural machinery safety guidelines; PTO guarding is critical. Active Features Pto Safety Features: Emphasis on proper PTO shaft guarding and engagement procedures for safe operation. Passive Features Pto Shaft Guarding: Manual implicitly requires proper installation and maintenance of PTO shaft guards. 💡 Technology Features Infotainment Infotainment Features: Not applicable to this vintage tractor model. Driver Assistance Driver Assistance Systems: Not applicable to this vintage tractor model. Connectivity Connectivity Options: Not applicable to this vintage tractor model. Pto Technology Pto Control Type: Mechanical lever engagement, likely with a multi-stage clutch system. 🔧 Maintenance Service Intervals Pto Lubrication Interval: Typically every 250-500 operating hours, but refer to specific recommendations in the manual for optimal intervals. Pto Clutch Adjustment: As needed, typically when engagement becomes difficult or slipping occurs. Manual will specify adjustment points. Fluid Specifications Pto Fluid Type: Refer to the tractor's main hydraulic/transmission fluid specification (UTTO, API GL-4) as the PTO often shares the same oil bath, unless a separate lubrication system is specified for the PTO unit itself....
