The present invention relates to a cleat assembly for a compactor wheel. The cleat assembly includes an adaptor for fastening to the compactor wheel. A cleat defines a recess in which the adaptor is receivable. A spring plate fastener has a strip of spring plate material, with opposed feet and at least one apex interposed between the feet. The adaptor and the cleat are shaped so that the spring can be received through both the cleat and the adaptor such the spring fastener is held in compression between the cleat and the adaptor, with the feet bearing against the cleat and the, or each, apex bearing against the adaptor to fasten the cleat to the adaptor. The cleat defines a pair of opposed apertures and the adaptor defines a guide formation, the apertures and the guide formation being configured to permit the spring plate to be inserted into engagement with the cleat and the adaptor from one of the apertures.
