The G20/40 is designed for smaller tractors from 20 to 40 HP. This is a great model for smaller tractors that provides the customer with the same Danuser quality and reputation. The G20/40 utilizes a straight bevel ring gear and pinion design. The G20/40 is the most copied digger on the market. Most diggers have a very similar gearbox design but don’t be fooled by the smaller and/or thinner gear set under the lid. 100% American made.
