Mitsubishi GSK20 – Full Specifications & Model Overview
The Mitsubishi GSK20 is a half-track crawler tractor designed for farms that need excellent traction on wet, soft, or sloped fields.
Produced from 2003 to 2005 as part of the GS Series, it uses an Isuzu 1.4L 3-cylinder diesel engine and a 12-speed transmission, providing a balance of compact size, power, and stability.
Its half-track system greatly improves grip and reduces soil compaction, making it ideal for rice paddies, vegetable farms, and mountainous areas where normal wheeled tractors can easily sink or slip.
