25-horsepower dry land crawler tractor

The 25-horsepower dry land crawler tractor, powered by a Quanchai engine with 2200rpm and an 8-speed gearbox (3 forward, 1 reverse with high/low range), delivers efficient operation at 1–2 mu/hour with fuel consumption of 1–2 liters/mu. Weighing 650kg and featuring dimensions of 2700×1060×1200mm (ground clearance approx. 190mm), it includes standard implements for rotary tilling (100cm), ditching (20×20cm), weeding (100cm), backfilling (100cm), and bulldozing (90cm). Optional attachments enable strawberry ridging, potato harvesting, straw returning, corn/wheat seeding, double plows, and hydraulic reversible double plows. The tractor uses belt drive, a water-cooled evaporative radiator (must not run dry), and a custom all-gear transmission with 180mm-wide crawler tracks (72×36).
