most likely your charge pump or main pumps are not working or being driving. From as simple as the belt not spinning them, to something after pulley, that is sheared or broken
The Bobcat 743 typically uses a hydraulic fluid that meets the specifications of Bobcat's recommended hydraulic oil, which is usually a high-quality hydraulic fluid such as ISO 46 or equivalent. It's important to check the operator's manual for specific recommendations regarding the type and viscosity of hydraulic fluid to ensure optimal performance and longevity of the hydraulic system. Regular maintenance and fluid checks are essential for the proper functioning of the machine.
Torque hydraulic motors is done by oil pressure and oil pressure is caused by the hydraulic pump. The hydraulic pumps produce higher pressure gets too much torque.
A hydraulic variable that describes the power provided by a hydraulic system. HHP is directly proportional to flow rate and pressure and inversely proportional to the efficiency of a system
Hydraulic machinery uses a liquid usually oil under pressure to transmit energy, hydraulic machine use the power of fluid to work, hydraulic machine are part of our everyday life.
It's a vice which is opened and closed by the application or release of fluid pressure. The hydraulic pump can be hand pumped or electrically operated.

Bobcat Fluid part number 6563328 or 10w-30, 10w-40 Class SE motor oil. Use 5w-30 where temps are below -10F.
The Bobcat 743 skid steer typically requires AW32 hydraulic oil. This oil is suitable for a wide range of temperatures and offers good performance in hydraulic systems. Always refer to the owner's manual for specific recommendations, as different operating conditions may require different oil specifications.

All Bobcats use Bobcat Premium Hydraulic/Hydrostatic Fluid.
If there is too much hydraulic fluid in a Bobcat skid steer, it can lead to increased pressure within the hydraulic system, potentially causing damage to seals, hoses, and other components. The excess fluid can also lead to overheating of the system, reducing its efficiency and potentially causing malfunctions. It is important to follow the manufacturer's guidelines for fluid levels and regularly check and maintain the hydraulic system to prevent overfilling.
