• Shutting off implements reduces horsepower drain and
wasted fuel.
• Reduces wear, extends equipment life
APPLICATIONS
WORK VEHICLE
• Confidential
Development
• Provides engine
power to operate
tools at work-site.
• On-off operation
conserves costly fuel
and wear and tear
on hydraulic
components.
WORK VEHICLE
GT2.5-BC01
GRAIN AUGER
• Brandt

Augers allow transfer
of grain between silos
and carts without the
need to use tractor
PTO power.
• Saves time
• Saves wear and tear on
tractor
• Saves fuel
GRAIN AUGER
• Hawes Agro
• Website notation:
• “The electric clutch
switch boxes are also
designed for safety,
durability and
convenience”
GRAIN AUGER
• Hawes Agro
• Clutch allows auger
disconnect when not
loading grain.
• Ease of use,
disconnects auger
for ground drive to
operate
independently.
• Fuel and equipment
conservation.

DO’S AND DON’TS
MOSTLY DO’S IN CLUTCH APPLICATIONS
MOUNTING
• DO make sure the
clamp load is
directed bearing
races when
mounting a clutch
or clutch/brake.
MOUNTING
• Bolt clamping force
is transmitted
through the washer,
output bearing
race, clutch rotor,
and field bearing
race. Clamps
against sleeve or
hub on engine
crankshaft.
