@andrewefridgway@ryan_milgate@dyerjonathan@simon_finlayson I have a rolling roof with an open front concrete walls divided into three sections. A very well built shed from Price fabrications in Williams wa. I keep fertiliser covered with sheets of plastic and that stops the crusting and lumps even after 12 months with urea potash mixes.
@HoolyMcg Do you take meter shaft out often? Rust and dust swell between plastic and metal spacers next to metering wheels acting like a brake causing clutch to slip.
I did have a loose nut on a shaft once causing cog to jump off drive pin and back on. Thought it was a bridging issue.
