Caterpillar WHEEL TRACTOR SCRAPERS 621K - catalog of spare parts
Fast loading, high speeds and the ability to load and unload on-the-go result in reduced cycle times, which allows Cat wheeled tractor-tractors to constantly deliver high performance with minimal cost per ton. Tractor performance improvement — the filter unit located at the rear of the engine compartment has undergone improvements for ease of maintenance by lifting the filter unit up for easier access.

Advanced hitch - thanks to technology similar to Cat® Advanced Ride Management seat suspension, this software allows the cushion suspension device to prevent the final stroke, being able to predict the final stroke events and control the speed of the damping. The desired result is improved hitch repair, reduced maintenance and an improved operator ride in rough conditions.
High Pressure Steering - The design of the 620K Series steering system requires significantly less effort when taxiing. Reduced steering effort will reduce operator fatigue and increase its efficiency, which will lead to possible higher production rates at the end of the operating cycle.
Overflow protection - Now open bowls are now standard with overflow protection on the side of the bowl to prevent material from entering through the edges of the bowl and falling onto the rods when the material falls between the edge of the bowl and the edge, resulting in reduced cycle times.
Auto Stall - in cold weather conditions, the car will use the Auto Stall function to help heat up the gear oil faster, which will cause the car to switch from the torque converter drive (2nd gear) faster than on previous models.
Differential lock protection (standard) —This standard feature allows the machine to prevent the differential lock from being activated when damage may occur.
Improved cab - The interior of the K-Series cabins has improved the convenience and visibility of the operator by changing the dashboard design and key layout.
Car speed limit - this feature is used to select the top gear. If it is necessary to limit the maximum speed of the machine, the operator can select the maximum speed using the display or the maximum speed can be set to ET. This will allow the car to find the right gear that is best for the engine and transmission. Allowing the engine and transmission to choose the right gear to pull the load in most cases, resulting in a lower engine load factor and a reduction in the number of burned fuel verses using top gear selection, which required the machine to operate at engine speeds at high revs or close to by him.
Stroke speed control - Stroke speed control sets the operator the desired maximum speed if conditions on the platform or segment speed limits require a speed that is less than full. The machine speed limit is intended for use when the maximum speed is to be limited for longer periods of time, and the travel speed control is for use when the maximum speed is to be reduced for shorter segments or intermediate periods of time. The operator can set the desired maximum speed, and the car will find the right gear, which is best suited for the engine and transmission. Allowing the engine and transmission to select the right gear to pull the load will in most cases reduce the engine load factor and reduce fuel consumption when choosing the top gear.
