Testing of fluid ~ has anyone ever tried this, and has it helped

[neetan]

Hello Forum,
Yes happy with my Hustler, but was getting ready in the next few weeks to pack my Hustler Fastrack SD 48" away for the winter. Came across this on the YouTube, & was wondering if anyone ever tried this, and has it helped?
