http://www.tractorsupply.com/webapp/wcs/stores/servlet/DisplayCategory_10551_10001_160821_14489__14455|14468|14489 I am employee of Tractor Supply Co. and get an employee discount, so my selection will be limited to the riding mowers sold at my store. I will be mowing about .75 acres of grass. I will also be using a tow-behind plug aerator and a tow-behind de-thatcher, so I want one with a strong engine and strong transmission. Which engine is better, a B&G Intek V Twin or a Kohler Courage V Twin? The Husqvarna YTH2454 is the only mower with the B&G Intek, most of the others have the Kohler Courage. What about transmissions?
