Every job has specific “tools of the trade” that workers rely on to get the job done right. What do you think would happen if a mechanic was given a new tool that was opposite from what they were used to using? I think we’d all agree that their production would take a hit as there would be a new learning curve to hurdle. Or how about if you were vacationing in a country where they drove on the opposite side of the street, and you needed to rent a car. You’d notice that the steering wheel was on the opposite side that you’re accustomed to. Yes, you would still be able to navigate the streets, but how efficiently and safely? Your brain would need extra time to process the simplest of tasks, like making a left or right turn, when it used to be a second nature move and required little or no thought.


Many heavy machine operators, or general contractors, who regularly rent machines like excavators and backhoes, run into similar problems. They’re working with a backhoe where they’re accustomed to the controls, and now tomorrow’s job requires the use of an excavator where the controls are totally different. As with the car example, they’d still be able to operate the machine, but at what speed, level of expertise, and safety standard?

IHI excavators offer a simple solution to this issue. Their quick-changing operating pattern selector (A to F Quick change valve) allows you to change an IHI excavator control scheme valve and instantly change from backhoe-style to excavator-style controls and vice versa with the flip of a switch. Yes, it’s that simple and fast. It’s essential for optimum performance to provide operators with the control pattern, digging position, and control feel they prefer. They become more efficient and productive when presented with the option of selecting a familiar operating pattern, eliminating potential problems and delays. Equipment rental companies benefit by keeping their customers happy and potentially eliminating added stress to their machine fleet.

Remember, a comfortable operator is a more productive operator, especially when working in harsh conditions and on jobs like trench digging. Just flip the switch, and you’ll immediately save time and money while decreasing potential job-site hazards and accidents.
