I am mowing bermuda grass. It is a viney type grass and my mower keeps pulling up the vines occasionally. Not sure what is causing it. My mower is self propelled older type commercial model 8430. I am used to red fescue and Kentucky blue grass as I am originally from the north and I now live in the South. Deck is clean and blade is sharp. Any ideas. Thanks in an advance
SK, how low are you cutting it? There are several ways to approach Bermuda - many people cut it very low. I'm in central VA and I cut mine at 3". This way it looks great all summer no matter how hot. Possibly at the higher cut, you won't tend to pull up the runners. Another Bermuda tip: for a bare spot or low area, just put down some sand/soil mixture - the Bermuda will fill it fast and the roots will hold it together.
Jack your mower all the way up. Water the snot out of it. Dump some 46-0-0 fertilizer at 3lbs per 1k sf. Then take a lawn chair and WATCH the grass grow. No more bare spots and an ultra thick turf. You will be the envy of the block.
