Electromagnetic PTO Clutches
for Outdoor Power Equipment
Electric PTO clutches provide a cost effective, reliable
means of mower deck and implement control while
increasing operator safety. The latest innovative
clutches from Ogura are patented under #US
Patent No.: US8,973,727B1.
Ogura manufactures a wide range of electric PTO
clutches that are used in riding mowers, zero turn
mowers, and commercial walk-behind mowers. Heavy
duty models provide extended life in demanding turf
care machines such as estate mowers, commercial
zero turn mowers, municipal lawn mowers and other
grounds keeping machinery.
Ogura, heavy duty, electromagnetic PTO clutch
brakes provide up to double the life of competitive
clutches as they can be adjusted for wear. This
provides a considerable cost saving and reduced
down time, since the clutch can be adjusted in
minutes while on the machine with a standard
Electric PTO clutches and clutch brakes are also
used to remotely engage the cutting wheel in saw
mills, stump grinders and log cutters. They are an
important element of “operator presence” controls,
where the operator can control the implement at a
In addition, Ogura PTO clutches are used in trenchers,
seeders, top dressers, fertilizer and herbicide
spreaders and sprayers. Cost savings and increase
profits can be realized through precise application
of seed, chemicals and top soil.
Solid forged rotor
A one piece solid forged rotor means no chance of
internal parts separation. Our rotors also have an even
wall thickness around the coil which gives optimum flux
distribution, maximizing torque.
Lead wire or terminal
Depending upon model and OEM preference, units
can either come with a lead wire, wire protector and
terminal, or have a built-in terminal.
High temperature, longer life grease
All models include our special long life grease which
has shown a significant improvement in life over other
standard high temp greases.
Where possible, all parts in the clutch are e-coated to
give maximum corrosion protection.
High temperature epoxy coil
To help prevent failure from both vibration and outside
contaminants, all coils are sealed in the coil shell with a
high temperature epoxy coating.
Heavy duty pulleys
All models use a heavy duty roll formed or machined
steel pulley. A stronger pulley resists damage due to
Reduced burnishing time
Reduced lighter duty units use a coating on the clutch
face that significantly reduces burnishing time. Higher
torque units come pre burnished to increase out of box
Soft-start control option
An optional electric soft start control can be added to
produce a softer engagement.
