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 4-1/4"pulley 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. As an additional benefit the blade tip speed is increased by using the smaller pulley providing improved cutting, so if you have an early model with 4-3/4" pulleys this is the correct replacement for your mower!
