I have a Knight 8018 bought new in 1996 and used on a 70 cow dairy until I quit milking. The sheet metal is still good.

Cousin bought a new 8124 in 2008. He used it on a 90 cow dairy until the metal got rusted out. It lasted about 13 years. I do not know what Knight did but it seems like the metal was changed between the 2 series of spreaders.

The good thiing about the Knight NO web to cause problems.
