Features :- Komatsu Skid Steer Loaders
- SK820-5
Maximum Performance and Precise Control with HydrauMind™
Komatsu’s smooth and precise HydrauMind™ system lets the operator feel the performance of the machine. The Closed Load Sensing System (CLSS) hydraulics are designed for both single and simultaneous movements which achieves unsurpassed control in positioning the bucket.
Standard Universal Attachment Quick Coupler
A universal quick coupler enables common attachments to be changed quickly and with little effort. Auxiliary hydraulics with flat faced connectors are standard. Most competitors’ attachments can be utilized on Komatsu’s skid steer loaders.
Easy to use Travel and Loader PPC Joysticks
Low effort Proportional Pressure Control (PPC) joysticks operate travel and loader operations. Easy to use PPC controls help operators of all skill levels work precisely and efficiently all day long – with minimum effort and reduced operator fatigue.
Two-Speed Travel
This allows for low impact shift-on-the-go speed changes between 6.5 MPH / 10.5 kph work range and 10 MPH / 16 kph travel range. Improves load and carry cycle times and travel times between job sites.
Vertical Lift-arm Design
Komatsu’s vertical lift-arm design makes it desireable for loading and unloading operations (especially with pallet forks). The front reach is kept virtually constant throughout the entire lift cycle.
Low Effort and Fine Hydraulic Control
The 16.1 GPM / 62 ltr/min auxiliary hydraulics can be metered from 3.7 to 1 to 16 GPM / 60 ltr./min or locked into continuous flow and the PPC pedal control results in low effort and fine control.
Automatic Power Control "APC"
Patented Komatsu anti-stall hydraulic system designed to allow full utilization of engine power. The operator can work with full engine power during the toughest job site applications without worrying about engine stall.
Outstanding Visibility
Work with confidence and increased productivity. The standard top and rear shatter resistant windows, large side screen area as well as a superior view of the bucket, cutting edge and corners give the operator excellent 360° job site visibility.
Optional "Super Flow" Auxiliary Hydraulics
The optional “Super Flow” auxiliary hydraulic circuit enables the SK820 to utilize many high flow attachments. Cold planers, stump grinders, flail mowers and other attachments can be easily operated with the PPC joysticks.
Intelligent Operator Controls
Komatsu has enhanced operator productivity and efficiency with their technologically advanced operator restraint bar. The operator restraint bar incorporates a LCD gauge panel and warning light system which is easily engaged and acts as a forearm rest. In addition, a Loader Arm Float Function control can be engaged on the joystick for enhanced back dragging or attachment applications.
Enhanced Loader Arm and Bucket Control
The hydraulic self leveling (up only) bucket with 4,200 lb / 1905 kg breakout force enhances the productivity of the operator on the job site. The 45° dump and 30° rollback angles of the bucket allow for a faster dump cycle and load retention over rough terrain.

Controls
Proportional Pressure Control (PPC) joystick levers. The left hand joystick controls the travel, the right joystick controls the loader equipment. The PPC foot pedal controls the auxiliary hydraulic circuit for attachments. A safety system neutralizes all operations when the operator restraint bar is raised or the operator is not seated.
