Common controls across the RTX lineup help the operator become more efficient and productive.
An integrated system display allows the operator to easily monitor important machine functions, while the capability to monitor percentage of hydrostatic capacity use is especially useful when training new operators.
The TrenchSense™ electronic control system can react faster than the operator to prevent engine stall/stop when difficult digging conditions are encountered. By eliminating the need to return controls to neutral and restart, productivity can be increased, and the whole sequence occurs within seconds.
The RTX550 is available in three ground drive configurations: a standard 31 in (78.7 cm) tire option, a 35 in (88.9 cm) tire option for enhanced flotation and quad tracks for reduced surface damage and increased tractive effort.
