The hydraulic system used on the HD99 is extremely reliable and requires very little maintenance compared to mechanical systems, and the HD99 uses high quality Parker components. All the maintenance that is usually required is to check or change the hydraulic fluid and engine oil and replace the hydraulic filter. The uniquely shaped fluid reservoir holds 3 gallons of fluid while having a large amount of surface area to dissipate heat for higher efficiency.
