I've tried sending my mower back to have the variable speed repaired. They don't seem to know what I'm taking about. I will either return the mower or fix it myself. Does anyone have any on what is involved? I'm guessing some type of rheostat on the drive trigger.
I agree, this seems odd, because this issue has come up a few times before. Ego would definitely know what you are describing. But first, maybe an easy fix, have you tried retracting and re-extending the handles firmly out all the way til you feel the click? From some experiences reported here, It seems the drivetrain interlock connection can jiggle loose if it wasn't engaged all the way and mess with SP performance.
I had problems controlling the speed when self propelled. Typically it raced around the yard faster than I could walk. I called customer services & was advised to take in to Home Depot. HD shipped the mower to a service center. I was contacted yesterday that parts are not available and, since the mower is within the warranty (5 yrs?), they are shipping me a brand new mower. I’m not happy I had the problem but I am impressed with the resolution.
I had the same experience last year as Paul Allen. Before going to Home Depot I tried calling the factory to see if the would send me the parts. I was advised to take it to Home Depot. I don't remember how long it was there but I did get the feeling that a repair was beyond Home Depots level of support for EGO units. EGO sent through Home Depot a new machine to me. I was also impressed by the outcome. I still think a part replacement would have been easier and less costly.
