Replaces OEM Part Numbers. Fits Models: Fits King Kutter: RFM-48, RFM-60, RFM-72 mowers that use a single drive belt. Specifications: Single Groove Pulley: 4-1/4″ NOTE: This spindle comes with a 4-1/4″ single belt pulley which is the standard replacement for all single belt King Kutter Finish mowers. Early models had a 4-3/4 blade pulley and complete spindles with that pulley are no longer available. King Kutter has said the 4-1/4′ pulley will work just fine as a replacement and that all new mowers have the 4-1/4pulley on them. No need to change the belt or idler pulleys, they feel there is enough adjustment in the tensioning system of the mower to accommodate the use of the smaller pulley. All three can be replaced with the 4-1/4 pulley with no problems. If you have a early model with 4-3/4 pulleys this spindle is the correct replacement.
