Originally designed by a road contractor for the
construction industry, the Cat® TS225 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. The exclusive walking-beam axle
provides a smoother ride for the operator and a variable
cutting edge angle for unmatch productivity. Designed
to be pulled by Caterpillar® Track-Type Tractors or
Challenger® Tractors, the Cat TS225 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 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,
reducing 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 high-strength,
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
Built rugged for extreme durability.
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)
pin securely held in place with 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 (or 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 convert the scraper hitch for pulling
drawn implements, such as disk harrows and sheepfoot
compactor rollers.
Robust, Straight-Line Design
Built from 13 mm (0.5 inch) 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.

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 formulated and
manufactured by Caterpillar to provide up to 20 times more abrasion resistance than industry-standard
hose. Cat XT-3 ES hose works at half of the SAE’s bend radius without sacricing cold ex capability.
As additional protection all exposed hydraulic lines are solidly secured with rubber-lined clamps,
protecting the hoses from failure caused by rubbing.
All hydraulic hose and lines use O-Ring Face Seal (ORFS) ttings for maximum leak prevention.
Steel Hydraulic Lines in Scraper 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.
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•
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.

Attachments
Lower the costs of Challenger® Tractors in scraper applications.
Rubber Track Guides
Rubber Track Guides for Challenger MTS800 Series Tractors
center the rubber tracks on roller wheels, and help prevent
the track from moving into the machine or detracking,
avoiding 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 Caterpillar 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. This reduces hose tting and valve wear for
increased service life.

Innovation
Exclusive Cat Features.
Walking Beam Suspension
The TS225 uses a four-tire arrangement with independent
walking-beam load transferring axles. The exclusive design
gives the scraper a smoother ride, reduced side-to-side sway
and easier nish grading.
Adjustable Cutting Angle
The TS225 is equipped with an additional pair of lift
cylinders at the rear of the scraper.
An experienced operator can use this exclusive feature to
“ne-tune” the cutting depth for improved productivity.
Steepen the cutting angle while drop cutting or during push
loading. Use a shallower cut when loading lighter materials
such as sand or dry topsoil.
Wheels, Brakes
Raising the Standards.
Standard Brakes – Construction-Grade
Standard heavy-duty brakes bring a new level of safety to
the job site. Each machine is equipped with four calipers.
The hydraulically-actuated, dry-disc brakes are identical
to the brakes used on Cat D400E Articulated Trucks.
Standard Radial Tires
Standard radial tires reduce rolling resistance and provide
excellent otation and durability. Heavy-duty, ve-piece
rims ensure a long service life. Wheel hubs are oil-lled
and sealed with Cat Duo-Cone™ seals.
