Rake Cleaner, Save More Leaves Like a mechanical pitchfork; with long flexible tines each ProRotor™ rake tine arm lifts and carries the crop delivering it into the windrow. The tines never need to touch the soil, so there is little risk of contaminants being swept into the windrow. The rotary action builds a well-shaped windrow without roping that promotes continued drying so you can rake earlier which helps retain delicate leaves producing higher quality forage.
