Three models of scrape sleds are available for under the grid. A painted model equipped with a forced-control wing mechanism is suitable for use in narrow and short channels.
A robust galvanized model is suitable for use in long and wide channels.
For freestall barns in which the cross channel is not at the end, a model is available with wing plates that turn around. This model picks up manure from the end of the channel and drops it in the cross channel, while at the same time turning the wing plate in the other direction.
