I've had great luck with the "Classic" style deck. It doesn't care for crabgrass much but then I've never seen a mower deck that did. The classic style deck can also be modified to suit your needs. There are a couple of things you can do with factory approval. The discharge side of the deck can be opened up a bit. They have a nose cone baffle that can be installed at the front of the deck. You can also raise and lower the leading edge of the deck about an inch. They also have a ton of blade options.
