Is a Power-Rake and De-Thatcher the same machine?

    I've been told by a professor at Purdue to place Roundup on my lawn in the fall to kill it off, then proceed with the publication they have on seeding in the fall. He stated that I need a Power-Rake to remove the dead turf. All the local rental units don't seem to know what a power-rake is but they all have a de-thatcher.

    Are these machines the same?

    Also, the ph.d. says that Roundup will not hinder the new seeds from germinating. What are your expert opinions on this?

    I have a nice turf-type kentucky bluegrass that has to be water every day in the summer. Almost every turf specialist recommends using a turf-type tall fescue. I currently have to overseed with a KBG to try to provide coverage to the dead spots that were killed by grubworms last year.

    If you have some lawn , even a thin one, I wouldn't "kill it off"

    simply Power rake or dethatch or just hand rake the dead material and remove it .

    Then Aerate and broadcast seed or slit seed the whole lawn with a drought resistant grass, Some blue grasses are more so than others , Turf fescues would be good also and will blend in pretty well. If the old blue dies out the fescue will take over, until then you still have cover.

    Also look at your watering and fert practices. If you always water every day then the grass expects it. It gets spoiled. the roots stay shallow because there is water there and they have no reason to go any deeper. Then when you miss a day the turf cant handle it.

    Start with infrequent deep watering in the spring when the turf isn't under as much stress. and keep this schedule through the season.
    Slow release fertilizer will also help promote deeper roots and stronger turf.

    To answer you original ?? if the machine is about 20 inches wide and has a 4 or 5 hp engine sitting to one side and 4 wheels.

    It can be called a power rake, a dethatcher a comber , a verticutter, a slicer and a couple other names.

    I will try find picture.

    Look underneath. there will be a shaft with either knives hammers or spring tines on it.

    Hope some of this helps.

    Others will probably chime in with there ideas on reseeding or overseeding as well.

    good luck.
