I just started a lawn care business and things are going well. 1 problem I am having is with my single wheeled Velke. It is leaving unwanted striping down the middle of my mower stripes. It makes it look like a 22' mower has cut the yard. Can anyone help with this? Are there Velke's out there that won't leave the unwanted stripes? On a separate not, if anyone knows of a good mulching or striping kit to add to my mower I would appreciate any leads. My mower is a 52' Exmark Turf Tracer WB. Thanks for your help.
