I bought cheap snap ring pliers to work with the snap rings on my backhoe. However, they didn't really work and I spent about an hour trying to remove the 1-1/2 inch locking ring. When I bought these snap ring pliers they worked great. In less than 10 seconds I can remove or remove the retaining ring. Install one of those big snap rings. These tools are worth their weight in gold. You will not be disappointed.
