About The Caterpillar 977 Crawler Loader

The Caterpillar 977 series track-loader was produced up until 1983. The Cat 977 was considered such an industry standard that over 22,000 units were produced, many of which are still providing meaningful earthmoving services for residential and commercial applications alike. Models after 1975 included a sealed and lubricated track (SALT) for durability and performance, which we provide parts for. When maintained with our high-quality undercarriage parts, these Cat 977 crawler loaders can stay on the job for a long time. Order our quality parts to help extend the life of your Cat 977 crawler loader.
