Factory installed hydraulic packages increase job site performance and versatility
Cat knuckleboom loader hydraulic systems are designed to satisfy the productivity demands of loggers. The 559B has an open-center, “Negicon” piston pump hydraulic system at its heart. This hydraulic system provides market leading performance and unmatched reliability which has allowed the 559B to be the market leading knuckleboom loader. Three operating modes are provided on the 559B allowing the operator to tailor his machine’s performance to match the job requirements. The “run” mode provides the best combination of fuel efficiency and performance; an “intermediate” position provides additional flow capabilities when higher production is required, and a “power” mode allows the full potential of the machine to come on-line to handle large timber and the heaviest delimbing requirements. All of the operating modes on the 559B provide the best multi-function ability, function response, control and fastest cycle times of any loader available in the market.
