Overview
The Cobra RM46SPCE is an electric start self propelled mower with a full width rear roller for that traditional striped finish. With an 18 inch cutting width the RM46SPCE can easily manage medium sized domestic lawns up to 600 square metres. Choose from 6 different cutting heights from 17 – 75mm for that ultra low fine cut. With a self propelled mower you just squeeze the handle and off you go. Fitted with a 135cc Cobra engine the Cobra RM46SPCE runs on unleaded petrol and 4 stroke engine oil. Cobra engines feature the latest engine technology for optimal torque and efficiency.
