Briggs and Straton OHV engine, 40 inch dual blade deck. Runs well, has been very reliable with good power and easy on gas. It is a Murray Pro Series Lawn tractor. This comes out of the same factory as the low-end big box John Deere tractors. Gear drive, 5 speed plus reverse. Recent oil change and tune-up. This tractor was bought in 2010 and has been used for three seasons then stored. Ready to mow, needs nothing.
