Originally designed by a road contractor for the
construction industry, the Cat® TS220 Towed Scraper
delivers outstanding performance and legendary
durability. High-strength, abrasion-resistant steel in the
scraper bowl minimizes wear. The rugged hitch, tongue,
and structural design ensure long life in the toughest job
site conditions. Designed to be pulled by Caterpillar®
Track-Type Tractors or Challenger™ Special Application
Tractors, the Cat TS220 Towed Scraper raises the standard.

Scraper Bowl
Unmatched Durability.
High-Strength Bowl Design
The scraper bowl is constructed using L-shaped box
sections of high strength steel for superior strength and
dent resistance. The oor is a box-section structure made
from high-strength, abrasion-resistant steel for maximum
strength during top loading and rigidity during intermittent
push loading. High-strength, abrasion-resistant steel is
used throughout the inside of the bowl for maximum
wear resistance.
Center Lift Design
The center bowl lift design improves the strength and
durability by placing the hydraulic cylinders between the
tongue and spreader tube. This eliminates the need for
draft arms, reduced weight and complexity.
Cutting Edges
Common Cat Wheel Tractor Scraper cutting edges and
router bits are used to ensure exceptional performance and
great availability. The center cutting edge is in the stinger
(drop down) position for good penetration and efcient
material ow into the bowl. When worn, the cutting edges
can be rotated by 180 degrees, doubling the life.
Ejector
The ejector is constructed from a single plate of highstrength, abrasion-resistant steel. The ejector extends beyond
the front edge of the scraper oor to minimize carryback.
To minimize wear, the ejector weight is carried on steel rollers
supported by a wear strip welded to the bowl oor. At the
sides, alignment is maintained by Ultra High Molecular
Weight (UHMW) plastic guides.
Depth Indicator
A depth indicator is mounted on trailing scrapers to provide
the operator a visual reference to scraper cut depth.

Tongue and Hitch
Rugged and Dependable.
Hitches for Cat® Tractors
Robust hitches are available for Cat® Track-Type Tractors
and Challenger MTS800 / MTS900 Series Tractors. See your
Caterpillar dealer for hitches for other pulling machines.
Rugged Hitch
To prevent pin wear, the hitch uses a massive 89 mm (3.5 in)
hitch pin securely held in place by eight bolts.
The hitch platform, positioned between the pulling machine
and the tongue, contains two pins that allow ± 45 degrees
of side-to-side oscillation (roll), ± 90 degree turns (yaw),
and ± 27 degrees of uphill/downhill movement (pitch).
An integrated stop block allows a 90 degree turning radius
while preventing contact between the tongue and the pulling
machine tires/tracks.
An adapter is available to quickly convert the scraper hitch
for pulling drawn implements such as disk harrows and
sheepsfoot compactor rollers.
Robust, Straight-Line Design
Built from 13 mm (0.5 in) structural plate steel, the tongue
is built to withstand the high drawbar forces imposed by
track-type tractors pulling towed scrapers.
The straight-line design eliminates draft arms, hydraulic
cylinders, and lines located outside the width of the bowl,
improving the overall strength to most effectively transfer
the drawbar power to the cutting edges.
Countersunk Tandem Hitch
A countersunk hitch is provided in the push block of lead
scrapers, allowing the scraper to be push loaded when
a second scraper is not used.

Attachments
Lower the costs of Challenger™ Tractors in scraper applications.
Rubber Track Guides
Rubber Track Guides for Challenger MTS800 Series Tractors
allow the rubber tracks to move and ride along roller wheels,
but do not allow the track to move into the machine and
causes expensive downtime. The track guides extend the
service life of the belt as the side-loading on the belt guide
blocks is reduced.
Detracking is generally caused by sharp turns, usually under
load. The rubber track guides can minimize tractor damage
caused by detracking, but are not a replacement for sound
operating techniques. Your Cat Dealer can provide training
in proper towed scraper operation.
Hydraulic Hose Hanging Tower Kit
The hydraulic hose hanging tower kit for Challenger
MTS800 and MTS900 Series Tractors allows the hoses to
move freely and eliminate entanglement while maintaining
vertical alignment for reduced hose tting and valve wear
to increase service life.
Wheels, Brakes
Raising the Standards.
Standard Brakes
Standard heavy-duty, construction-grade brakes bring
a new level of safety to the job site. Each machine is
equipped with four calipers. Brake components are the
same as were used on Cat Articulated Trucks.
Standard Radial Tires
Standard radial tires reduce rolling resistance and provide
excellent otation and durability. Heavy-duty, ve-piece
rim ensure a long service life. Wheel hubs are oil lled
and sealed with Cat Duo-Cone™ seals.

Hydraulics
Tough components for tough applications.
Hose and Couplings
Cat XT™-3 ES (Enhanced Spiral) hose is used. Cat XT-3 ES
hose has an exclusive cover which is formulated and manufactured
by Caterpillar to provide up to 20 times more abrasion resistance
than industry-standard hose. Cat XT ES hose works at half of
the SAE’s bend radius without sacricing cold ex capability.
As further protection, all exposed hydraulic lines are solidly
secured with rubber-lined clamps, protecting the hoses from
failures caused by rubbing. All hydraulic hoses and lines use
O-Ring Face Seal (ORFS) ttings for maximum leak prevention.
Steel Lines in Bowl Walls
Brake lines and hydraulic lines for the rear scraper in tandem
arrangements use steel lines inside the scraper bowl walls
– eliminating hose damage caused by material in the bowl
or during top loading.
Cushion Hitch
The optional cushion hitch adds two hydraulic accumulators
to the scraper bowl lift circuit. When the operator activates
the cushion hitch feature during transport, the accumulators
allow the scraper bowl lift hydraulic cylinders to act as shock
absorbers. The cushion hitch can be used in single scraper
operations or by a lead scraper in tandem operations when
pulled by a wheeled agricultural tractor.
Hose Fittings
Three hose tting options are available:
19 mm (3/4 in) poppet-style•
13 mm (1/2 in) poppet-style•
Threaded at-face connectors•
Easy-To-Use Connectors
Threaded at-face connectors, available exclusively on
Cat Towed Scrapers, allow connection and disconnection
under pressure and are less susceptible to wear caused
by hose movement.
