ENGINE DETAIL
The ATC GT-30 features a Continental gasoline engine with a liquid-cooled 4-cylinder configuration that provides a displacement of 2.3L, optimizing it for efficiency in agricultural tasks. With a low compression ratio of 6.5:1, it ensures lower stress on the engine at a rated RPM of 1850, making it suitable for prolonged operations while maintaining reliability. However, the 6-volt starter system may present challenges in cold starting conditions compared to 12-volt systems, necessitating consideration for operational environments.

ATC GT-30 ENGINE
The ATC GT-30 tractor is powered by a Continental 2.3L 4-cylinder gasoline engine providing adequate power for medium-duty tasks. With a 10-gallon (37.9L) fuel tank, it offers reasonable operational range, though frequent refueling may be necessary for sustained use. Pros include lower emissions compared to diesel and easier starting, while potential challenges might involve lower torque output and fuel efficiency under heavy loads.

TRANSMISSION
The ATC GT-30 tractor features an unsynchronized gearbox with 3 forward and 1 reverse gear, allowing for straightforward operation but with less flexibility in handling varying loads compared to synchronized systems. The dry disc clutch provides reliable engagement and durability in demanding conditions, though it may require more maintenance due to wear and tear. Ideal for basic agricultural tasks, this configuration may face challenges in precision applications where gear shifts need to be executed smoothly without stalling.

MECHANICAL
The ATC GT-30 tractor features a crawler chassis, offering enhanced stability and traction in rough terrain, making it ideal for agricultural applications or construction sites. Its manual steering may pose a challenge for extended operation, leading to operator fatigue, while the mechanical contracting band brakes provide reliable stopping power but may require more frequent maintenance than hydraulic systems. The 3-speed unsynchronized gear transmission allows for simpler construction but requires skillful operation during gear changes, which may limit efficiency for less experienced operators.
