The Hart-Parr 20-40 is a classic tractor made by the Hart-Parr company. This tractor uses a gear transmission, which was common for tractors of its time. The gear system helps the tractor change speeds and pull heavy loads.
The 20-40 has an engine made by Hart-Parr itself. This means the company built both the tractor body and its engine. Having the same company make both parts can help everything work well together. The tractor doesn't have many extra features, which makes it a simple and straightforward machine for farmers to use.
