Cat large wheel loaders are lemons, especially the 994. The only place they’re interesting are on stockpiles and stockpiles are a waste that should be removed through other means (and are in this low cost environment) combined with the existing fleet which doesn’t need replacement for a few years.
Cat in general has a reliability problem. You can get higher reliability through their competitors at a lower cost. Cat also is lacking on the service side: they don’t do it well and it should be part of a total package.
My niece and her husband both work for Cat. I was kind of surprised to learn that customers had to buy support after purchasing the machines. They just spent two years in Chile, three years in Timmons, ON prior to that.
