I have a 1989 Toro Mower powered by an 18 hp kohler twin cylinder Engine. I did a valve job on it 4 years ago, and put in a new Ignition module and fuel pump at that time. The mower has developed the annoying habit of shutting down after about 15 minutes of operation. Let it cool off and it starts again, 15 minutes and it shuts down, starting the process all over. Im thinking that I got a defective module or fuel pump, but thought I would check in with the group to see what the next move is to determine the problem,

We mow about 2.5 acres and currently have a cub cadet z-force 60 inch zero turn mower. It takes about 1.5 hours to mow. There are only about 8 trees and 2 sheds to mow around. The zero turn is so rio ugh if a ride that it hurts my back and neck after mowing about 30 minutes. I am thinking that a regular garden tractor would be more comfortable but this is the only mower I've owned so I don't know. Am thinking of selling mine and buying a regular lawn tractor if it would increase the comfort and not add too much time to mowing. -how long would it take to mow with a good lawn tractor and 48-52inch deck? Some are listed at 7 mph which is the same as my zero turn -is a lawn tractor gong to be more comfortable on uneven/rough terrain? -my cub has a 23hp Kawasaki engine and only 196 hours. It is a few years old but it good shape. How much do you think I could sale it for? Thanks
