My husband & I bought a Cub Cadet "The Tank" zero turn radius mower (commercial grade) 48" cut in April, 2007. Brand new. We do lawns commercially. Any time my husband mows with it he can't get more than 10 hours to a set of blades which cost between $50.00 & $60.00 for a set. Usually he gets less than 10 hours. The mower doesn't seem to discharge the grass out from under the deck so it gets guilt up & wears the blades out. We wash under the deck but when you are mowing a yard that takes 4 to 6 hours to mow you can't stop & wash the deck every hour. This cuts into your time and money. I am wondering if anyone else has this problem with the same machine? We have asked the dealer & he says he hasn't had any other complaints.
I bought a new 48" Tank in July 2006 and have the same trouble with grass build up and failure to discharge properly. I assume it's the nature of the deck design, which is clearly flawed.
