Geared Kit: This is the cheapest solution. A separate electric motor must be fixed to the steering column, which drives a gear ring mounted on the factory steering wheel. Its installation requires a bit more DIY work. Its setup is slightly more difficult. Direct Drive Kit: This is currently the most popular choice. The tractor’s factory steering wheel is removed and replaced with a complete steering wheel integrated with a powerful built-in electric motor. This solution is incredibly quiet, aesthetic (factory look), much simpler to install, and has more precise power transmission.
