Sorry I should of said. It’s one metering unit on a 4m combi and it’s land wheel drive. Speed won’t be any more than 4-5km/hr as it’s rough hence the combi being used.depends on ground speed, too fast churning max rate on could break the plastic sprockets, also how many meters of drill per feed unit?
Clock doesn’t work I’m afraid so we are just doing the set number of turns and then multiplying. But go drilling and on the RTK steering system it’s working out at 225kg as well off the area measured. It’s as if physically it won’t discharge any more than 225kg/ha but as said it’s rarely used and generally would of been used at 150kg/ha so it may of always been like this and we’ve never known.So how much are you collecting and what does the clock say at calibration?
