I have had since 2001 a eXmark Lazer Z HP and will be replacing my first pump drive belt. Before I get into this project can anyone tell me if there are any potential problems I should look out for? Any special tools required? I usually don't ask these questions in advance when a repair looks simple enough and my failure to do so sometimes bites my in the butt. Any input you pros have would be greatly appreciated. By the way ............ anybody know what happened between Terry and eXmark? Any problems at eXmark we should know about? I do know they are not responding to email inquires at exmark.com.
