The Komatsu SK1020-5 skid steer loader has one of the longest wheel bases in its class, 45.7 in. (116 cm), giving the operator a more stable ride and a better platform for operating high flow attachments. The machine’s hydraulic self leveling (up only) bucket with 5,038 lbs. (2,290 kg) of breakout force enhances operator productivity on the job site. The 45-degree dump and 30-degree rollback angles of the bucket allow for a faster dump cycle and load retention over rough terrain.
Komatsu’s SK1020-5 has two-speed travel that allows for low impact shift-on-the-go speed changes between 6.5 mph (10.5 kmh) work range and 10 mph (16 kmh) travel range. This feature improves load and carry cycle times and travel times between job sites.
The machine also is equipped with Komatsu’s anti-stall hydraulic system, designed to allow full utilization of engine power. This allows the operator to work with full engine power during the toughest job site applications without worrying about engine stall. The standard top and rear shatter resistant windows, large side screen area as well as an enhanced view of the bucket, cutting edge and corners give the operator 360 degrees job site visibility.
Komatsu’s SK1020-5 has low effort proportional pressure control (PPC) joysticks that operate travel and loader operations. The PPC controls help operators of all skill levels work precisely and efficiently all day long — with minimum effort and reduced operator fatigue, according to the manufacturer.
The closed load sensing system (CLSS) hydraulics are designed for both single and simultaneous movements. This achieves control in positioning the bucket.
A universal quick coupler enables common attachments on the SK1020-5 to be changed quickly and with little effort. Auxiliary hydraulics with flat faced connectors are standard, and most competitors’ attachments can be utilized on Komatsu’s skid steer loaders.
The optional “super flow” auxiliary hydraulic circuit enables the SK1020-5 to utilize many high flow attachments. Cold planers, stump grinders, flail mowers and other attachments can be easily operated with the PPE joysticks.
Komatsu has enhanced operator productivity and efficiency with its operator restraint bar. The operator restraint bar incorporates an 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.
