Blade, Buckets and Cutting Edges Flashcards
This piece of equipment often endures the harshest conditions therefore they are constructed strong and rigid.
Crawler Tractor
__________ is not recommended because it will also accelerate the wear of the fasteners that
secure the cutting edge to the blade.
Back blading
The blade is often mounted on the C-Frame. The C-Frame is normally mounted on a _____________
trunnion.
____________________ mounted to the C-Frame and the blade
will assist with tilting the blade.
Hydraulic cylinders
Some units without hydraulic cylinders will use __________________ on the sides of the C-Frame to tilt the blade.
mounting sockets
Some lift cylinders are designed to assist with _____________
engagement using a downward hydraulic force.
deep ground
Some lift cylinders hydraulic systems are fitted with a
______________ feature which allows the blade to travel with the lay of the land.
float
Float: used for rough finishing. Less suitable for ______________
soft ground.
_________________ is high strength, heat-treated and hardened edge to penetrate the ground while protecting the blades.
cutting edges
_______ are used to cut in to ground material and transport that material to
another part of the job site.
Motor scrapers
for motor scrapers, cutting edges are mounted ________ to
assist in engaging the ground.
on the bottom section of the bowl
What allows the operator to make a narrow single pass with a motor scraper?
When the centre cutting edges are slightly deeper than the rest
In a motor grader, the __________ cylinder allows the operator to move the material
into or out of his wheel tracks.
side shift
The curved portion of a grader blade is often referred to as the
______________
moldboard.
What is the function of the moldboard?
The moldboard helps curl the dirt so that it goes to whichever
side the blade is angled.
What can be done to increase the life of a cutting edge in a motor grader?
Some cutting edges can be turned before replacement is required.
What are scarifiers?
The teeth like design on cutting edges used to loosen material or for icy roads
Never use __________________ to align the mounting holes when installing attachments.
Never use your fingers or hands
Loader buckets often have a _________ on the lower side to
protect the bucket when the loader bucket is gathering material.
cutting edge
Why do loaders have cutting edges on the top side of the blades edge?
to prevent wear on the top side of the bucket
The holes on the side of the bucket are for installing ____________________
cutting edges to the side to aid in penetration and wear protection.
Rippers are used for:
hard ground material that need to be loosened.
Some rippers have hydraulic pin pullers. What are these for?
To aid in changing the depth of the ripper.
What is the difference between a ripper and scarifier?
A scarifier is like a ripper, but much smaller, they are only used to break up the top layer of ground.
What is the benefit of implement quick attach?
Versatility: increase productivity, reduce equipment costs.
With a _________ inspection, you should always clean your attachments and inspect with them out and
off of the ground.
visual
True or False: The type of soil does NOT have an impact on the bucket’s payload.
False
When hard surfacing a bucket, a crosshatch; waffle type pattern is commonly used in order to?
Trap dirt and small particles in order to aid in less bucket ware.
When torquing a plow bolt with no OEM spec provided, what would be the recommended torque value for a 1” plow bolt?
850 +/- 110 ft/lbs.
If a tooth is found to have a crack in the pocket area, what should be done?
Replace it
The actual weight of material in the bucket on each digging cycle is referred to as:
Pay load.
The payload that causes both rear wheels to leave the ground with the lift arms horizontal is labelled by the SAE (society of automotive engineers) as:
Tipping capacity.
The most used rating for bucket capacity gives an approximate amount of cohesive soil that a bucket can hold is:
Heaped capacity.
When installing new teeth that are mounted on pins it is recommended that a technician:
Install new pins and retainers.
SAE J818 states that the rated operating payload is what percentage of the tipping capacity?
50%
Following a proper Preventive Maintenance program, working attachments, such as cutting edges, should be inspected:
Inspected Daily
