An attachment is only as strong as the host machine that provides its hydraulic power," notes Kelly Guthrie, marketing, Coneqtec/Universal. Consequently, cold planer attachments and skid-steer loaders must be properly matched to ensure optimum performance.

It's important not to underestimate the hydraulic demands that will be placed on the carrier. "Case does not recommend using a planer that is oversized for the base unit," says Bill Harris, attachments engineer, CNH. "Some skid-steer manufacturers tend to be optimistic regarding the maximum hydraulic output, and some planer manufacturers tend to be optimistic regarding minimum requirements. If the loader just makes the planer's recommended requirements, the user will likely be disappointed with performance."

Also consider engine speed. "Available horsepower is critical to production," Harris states. "There needs to be enough engine horsepower left for traction."

According to Justin Odegaard, attachment product specialist, Bobcat, "The machine needs to be run at high idle, or throttle open completely, in order to achieve maximum horsepower. Some contractors will run at three-quarters of maximum to save fuel." Yet, this can prove counterproductive. "The engine actually has to work harder to achieve the performance required for the planer attachment."

He adds, "Planers are one attachment where it's hard to have too much power. More power will typically make production increase."
