Thanks for your feedback! Sorry you were given the wrong instructions. If you go to Toro.com, click 'Parts and Manuals', and type the model number for your attachment, there will be the operator's manual for your product available for free that has the correct instructions. For the best striping results, take a look at our Lawn Striping "How to" video that can be found at Toro.com/helpcenter under the lawn mowers category. For the 30" mower attachment, there is also another video found on the Toro website by simply typing your model number into the search bar and clicking on the product. There you will find a variety of pictures and videos near the product description, including one on the 30" striping system. If you require any assistance, please call us at 888-384-9939. We hope you like the striping kit more with every use!
