Some of the time when I try to move it, or make a turn at the end of a row, the right wheel &#8220;locks&#8221;. This isn&#8217;t an issue when making right pivoting turns, but when you are trying to pivot around the left wheel and the right wheel locks up, it stops the turn.<\/p>\n<p>It appears to happen both with or without the mower motor engaged. It sort of acts like the &#8220;anti-roll-back&#8221; feature, except that I&#8217;m not trying to make the mower go backwards, and it&#8217;s always the right wheel that locks up, never the left.<\/p>\n<p>I had never noticed this behavior before a month ago, so it appears to be a newly developed issue. So far the self propel unit is working fine when engaged, but given my <a href=\"https:\/\/www.summet.com\/blog\/2020\/01\/20\/ego-21%e2%80%b3-mower-lm2100sp-3rd-self-propel-motor-failure-repair-report\/\">history of self propel unit failures<\/a>, I&#8217;m concerned that this quirk may indicate something in the motor control unit is having issues&#8230;<\/p>\n<p><strong>June 2021 Update:<\/strong><\/p>\n<p>The issue shown in the above video kept getting worse until I called Ego support and described it to them. They immediately sent me to the local Ego certified repair place who fixed the issue in about a week. The issue was that the nylon gears at both ends of the drive shaft (as well as the plastic gears inside the wheels) were worn down and slipping\/jamming. The shop tech said that he replaced both the motor\/drive unit and both wheels. Here is a photo comparing what the nylon gears are supposed to look like with what the actually looked like.<br \/>\n<a href=\"https:\/\/www.summet.com\/blog\/wp-content\/uploads\/2021\/05\/ego_nylon_gears_worn_down-scaled.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-large wp-image-5432\" src=\"https:\/\/www.summet.com\/blog\/wp-content\/uploads\/2021\/05\/ego_nylon_gears_worn_down-1024x768.jpg\" alt=\"\" width=\"584\" height=\"438\" srcset=\"https:\/\/www.summet.com\/blog\/wp-content\/uploads\/2021\/05\/ego_nylon_gears_worn_down-1024x768.jpg 1024w, https:\/\/www.summet.com\/blog\/wp-content\/uploads\/2021\/05\/ego_nylon_gears_worn_down-300x225.jpg 300w, https:\/\/www.summet.com\/blog\/wp-content\/uploads\/2021\/05\/ego_nylon_gears_worn_down-768x576.jpg 768w, https:\/\/www.summet.com\/blog\/wp-content\/uploads\/2021\/05\/ego_nylon_gears_worn_down-1536x1152.jpg 1536w, https:\/\/www.summet.com\/blog\/wp-content\/uploads\/2021\/05\/ego_nylon_gears_worn_down-2048x1536.jpg 2048w, https:\/\/www.summet.com\/blog\/wp-content\/uploads\/2021\/05\/ego_nylon_gears_worn_down-400x300.jpg 400w\" sizes=\"auto, (max-width: 584px) 100vw, 584px\" \/><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>My 21 inch Ego mower with the updated self propel unit has developed an annoying quirk.
