Backhoe Performance
The new E-Series Backhoe improves performance and serviceability
Excavator-style Backhoe
The instantly recognizable Cat excavator boom
has more than just good looks – it outperforms
straight boom designs too. Whether close-up truck
loading on a single road carriageway, or digging
over obstacles such as walls, the excavator boom
outperforms the rest. Combine this versatility with
the powerful breakout forces, the controllability of
the load-sensing, flow-sharing hydraulic system,
and you have one of the best Backhoes' in the
industry. The boom is a narrow design, ensuring
maximum visibility to the work tool.
Extendable Stick
The 434E is available with improved extendable
stick. Redesigned with the sliding outer section,
this design keeps the wear pads out of the dirt,
extending adjustment intervals. When adjustment

Hydraulics
Load sensing, flow-sharing system matches power and flow supply to demand –
where you need it, when you need it.
Hydraulic Performance
It’s rare that you’ll be working at full production 100%
of the time, so why should the machine be working flat out,
using more fuel, making more noise, and increasing wear?
The 434E has a load-sensing, closed center hydraulic system,
which closely matches power and flow to the demand needed
by the implements. So whether you’re in full trenching mode,
or delicately digging around services, you are in control.
In applications such as loading and carrying, speed is
important, and system will match the flow needed to get
the job done quickly and efficiently.
As there is minimal demand on the system unless needed,
there are less parasitic hp losses and more power available
for rimpull – providing better loading and roading.
12
Flow Sharing Valves
The 434E also features flow-sharing hydraulic valves,
ensuring the correct flow of oil reaches the implement
cylinders, providing greater control and eliminating oil
starvation when operating multiple functions, such as when
grading with the backhoe.
Hardware
The 434E is equipped with a highly efficient variable
displacement piston pump, Cat's XT hoses and O-ring face
seal fittings, ensuring a robust system. XT hose is constructed
from four over-lapping wire spiral wraps, ensuring excellent
durability and resistance to damage from pressure spikes
and hydraulic pulsing.
Serviceability
Lower operating costs mean a better return on your bottom line.
Reduced Maintenance
The 434E is equipped with a flip open hood, allowing access
to all check/fill points, air cleaner, washer bottles, visual indicators
etc. The E-Series carries on the tradition with sealed for life axle
oscillation, driveshaft universal joints, trunnions etc.
Daily maintenance, which can be a chore for the busy operator,
is kept to a minimum on the 434E.
Boom and Stick Design
The Boom and Stick design allows all wear adjustment to be done
with Stick in-situ, using a simple wedge adjustment mechanism – no
dismantling to shim the wear pads. The Stabilizer legs are also
externally adjustable, reducing machine down time and inconvenience.
Cat Filters
All Cat filters are vertically mounted for spill free servicing and
reduced oil contamination. They are also low micron filters, filtering
even tiny particles from the oil and keeping the engine, transmission
and hydraulic system running smoothly for years.
Scheduled Oil Sampling
Your Cat dealer will be able to provide the Caterpillar Scheduled Oil
Sampling (S•O•STM) service. This enables your dealer to analyze wear
