Just looking at an engine’s horsepower isn’t enough.
You have to see how much power is delivered to the ground.
Competitor Undercarriage
1. Engine
2. Hydraulic pump (about 2% hp loss occurs here)
3.-8. Hydraulic block, plus each hydraulic union and fitting is a point where hydraulic pressure can be lost. Loss of pressure means loss of power (about 8% hp loss occurs here)
9. Hydraulic wheel motors (about 5% hp loss at each wheel motor)
More horsepower is required to:
- Lug around 3,000 to 9,500 pounds of extra weight, including four hydrostatic wheel motors and pumps.
- Compensate for wasted power; 25-40% of the horsepower is lost before it even hits the ground.
With some hydrostat drive, power to the ground is complex and inefficient:
Apache Undercarriage
Apache POWER-TO-the-GROUND™
A full 90 percent of Apache Sprayers horsepower is transferred to the ground, compared to 70 percent from other sprayers. In fact, the Apache’s lighter construction provides more Power-to-the-Ground™ than competing sprayers. That way you get a lot more from your horsepower.
