First time writing about mower, it is little hard to decribe the situation, but i will try.
I have dynamark 11/36(if it's correct name). First, battery ran out, so I hooked up w/ my alternative battery. Now, ignition sounds pretty good and all the drive chain starts rotate and even grass cutting knife works too(turns). Problem is it doesn't stay running. if I turn the key to the original position engine stops. any idea which parts i should be looking at to fix and what is the problem at least?
