Hydraulics

Equipped with an all-new hydraulic system, MT900C Series tractors offer more flow, more versatility and more efficiency than ever before. Four electric over hydraulic circuits are standard on all models with a fifth or sixth valve available as an option for more demanding applications. 

The closed center, load-sensing, pressure-flow compensating system has an industry leading 43.5 gal./min. (164.7 lpm) pump as a standard feature. For the truly demanding applications, like large planters or scrapers, Challenger offers a 59 gal./min. (223.3 lpm) pump option that doesn’t make you choose between pulling power and hydraulic flow. 

ISOBUS control of all remote implement valves also allows the operator to electronically adjust flow rates, adjust timed detents and precisely adjust individual valve operation from the cab’s Tractor Management Center. The redesigned system, which utilizes a separate controller built into each valve, even allows the operator to direct continuous flow up to 36 gallons/min. (136.3 lpm) through any one coupler. This is particularly important in applications like seeding, where uninterrupted oil flow to a hydraulically driven vacuum system is critical. 

Exclusive to Challenger, Load Independent Flow Division (LIFD) is another indispensable feature when using hydraulic-powered equipment. Instead of diverting hydraulic flow from one job to another, LIFD ensures proportional oil flow to all desired circuits when the system is operating at full capacity. The exception is when one valve has been given priority to receive full flow up to 36 gpm (136.3 lpm). In that case, all other valves divide the flow evenly, which means you get the best of both worlds.
