A grain cleaner is taught including features for facilitating maintenance and repair of the cleaner over previous grain cleaners. In particular, the grain cleaner has an indent cylinder assembly which includes a removable cylinder. The cylinder is removed by unwrapping it from around a frame. The grain cleaner also includes at least some augers with drop away troughs. The grain cleaner also includes grain cleaning assemblies such as, for example, indent cylinders and rotary screen drums and/or grain cleaning assemblies drive systems which are mounted on framework members capable of pivoting outwardly from the machine allowing access to machinery and components positioned centrally within the grain cleaner.
