Introduction

Gravely 8128 Garden Tractor

The Gravely 8128 is a garden tractor model produced in 1980, designed for residential landscaping and property maintenance tasks. It is part of the broader Gravely 8000 series, known for its mechanical simplicity and shaft-driven drivetrain architecture.

Engine and Powertrain

The tractor is powered by a Kohler K301 gasoline engine, a single-cylinder, air-cooled unit with a horizontal shaft. It delivers 12 horsepower (8.9 kW) from a displacement of 476 cc. The engine utilizes an electric starter powered by a 12-volt electrical system with a 42 Ah battery, ensuring reliable ignition.

Transmission and PTO

The drivetrain features a shaft-driven gear transmission, providing 8 forward and 4 reverse speeds. The system uses a dual-range configuration with forward and reverse clutches, requiring the directional clutch to be in neutral for gear or range shifting. A mechanical clutch controls the independent mid-mounted PTO, which operates at 1000 RPM to drive various implements.

Chassis and Handling

Built on a two-wheel drive chassis, the 8128 features manual steering and mechanical band brakes for operator control. The machine has a wheelbase of 52 inches (132 cm) and a total shipping weight of 890 lbs (403 kg). It rides on turf-specific tires, measuring 16x6.50-8 at the front and 23x8.50-12 at the rear, providing a ground clearance of 7 inches (17 cm).

Conclusion

The Gravely 8128 is a compact, utility-focused garden tractor suitable for homeowners and small property owners requiring a durable machine for mowing and light attachment work. Its shaft-driven design and independent mid-PTO make it a robust choice for those prioritizing mechanical reliability over modern electronic features.
