Hello Eleanor Rigby,

We appreciate your feedback on these matters and thank you for taking the time to leave this review. It is unfortunate to hear that the cut is less than satisfactory for you. Please try out the following suggestions to see if these help. 1) When cutting thick grass, reduce walking speed in order to allow for a more effective cut and a proper discharge of the clippings. 2) Only mow 1/3 of the total grass length at a time. For a healthy lawn, always cut off one-third or less of the total length of the grass. The average lawn should be approximately 1 1/2 to 2” (3.8 to 5 cm) long during cool months, and between 2" to 3 1/4" (5 cm to 8.3 cm) long during hot months. 3) Mow when the grass is dry. As this is an electric unit, mowing wet/damp grass is a safety issue. However, ensuring the grass is dry will also help the grass cut cleanly and discharge appropriately. Wet/damp grass carries more weight and will mostly stick to the blade/motor shaft and will not appropriately discharge or cut easily. 4) Alternate mowing patterns each time you mow. As grass develops a grain based on your cutting direction it will lean towards the direction of your mowing path. Changing the pattern allows better vertical growth and helps to keep the cut neater. For best results keep the grass under 4" in length and walk at a slow but steady pace to allow the blades to cut efficiently. A sharp blade will greatly enhance the performance of the mower, especially when cutting high grass. Be sure to check the blades and to sharpen them or replace them at least once per year. We hope these tips will help you with the issues you have encountered, however, if they do not please kindly contact us at 1-855-345-3934 or by email on info@greenworkstools.com.
