Scag Driveshaft Driven Cutter Decks
High
performance, high horsepower machines require high strength drive
components and drive systems to ensure reliability and productivity.
Scag understands this requirement and it is apparent in the design
of every mower we build. Here's an overview of how we transmit
solid, no-slip, reliable power to our cutter decks.
- The engine powers a heavy duty Ogura electric clutch.
- The Ogura clutch turns a Scag tough drive spindle via a self-adjusting,
Kevlar corded belt.
- The drive spindle is directly attached to a double-clamped driveshaft
that runs to the cutter deck.
- The driveshaft is attached to a simple, 90 degree gearbox that
transmits power to the Kevlar corded, self adjusting spindle drive
belt.
- The self-adjusting spindle drive belt turns the blade spindles
that are attached to the cutter blades.

 Ogura PTO Clutch Brake
The
engine delivers power to a dependable Ogura
electric PTO clutch brake. The Ogura clutch
is attached to a drive spindle via a Kevlar
corded drive belt . The belt tension automatically
adjusts as needed and the belt runs on
a flat plain. No twists or turns that can
shorten belt life.
The Ogura clutch is a true, heavy duty component that allows for airgap adjustment
as the clutch starts to wear. What does this mean to you? It means that instead
of replacing a clutch because it has some normal wear, your Scag
Dealer can make a simple adjustment and make it like new again. |
 Driveshaft to the Cutter
Deck
The
driveshaft runs from the rear drive spindle
to the cutter deck. Using a driveshaft
ensures there is no belt "slip" from
the engine to the cutter deck. It enables
you to retain proper blade tip speeds in
heavy, high-speed cutting conditions. It
also provides increased reliability and
longevity compared to a twisted "mule" belt
drive system.
A simple 90 degree, aluminum gearbox converts the drive from the shaft to a cast
iron or split-steel pulley and self-adjusting belt system on the cutter deck.
The gearbox features a seal protector to shield the input seal from debris damage.
A Kevlar corded, self-adjusting drive belt runs from the gearbox to the cutter
blade drive spindles. |
 Self-Adjusting Belt
Systems
Every belt
on every Tiger mower is self-adjusting
for minimal maintenance and maximum life.
Idler arms utilize sealed bearings eliminating
the need for routine service, and that
saves you time. All belts are constructed
with super strong Kevlar cords rather than
the standard polyester type belt cords
that can stretch and fail prematurely.
Every pulley used on Scag equipment is
either cast iron or split-steel for extra
reliability. No plastic, light-duty pulleys. |
