what is the warranty that wright offers on their mower decks. My main question is how the handle cracks that appear in the deck on the 61 stander. I own two of these units and both have developed cracks on the top portion of the deck at the corner of the deck cover(spindal cover). Both have about 500 to 600 hours on them. I have had the cracks welded by my dealer but I am not sure how long this will last til the crack reappears. Is this a normal problem and is ther anything that could be done to avoid this situation. thanks for your help.
