Safety Instructions
The ProCore 864 and 1298 are designed and tested to
offer safe service when operated and maintained properly. Although hazard control and accident prevention
partially are dependent upon the design and configuration of the machine, these factors are also dependent
upon the awareness, concern and proper training of the
personnel involved in the operation, transport, maintenance and storage of the machine. Improper use or
maintenance of the machine can result in injury or
death. To reduce the potential for injury or death, comply
with the following safety instructions.
Before Operating
WARNING
To reduce the potential for injury or death, comply with the following safety instructions.
1. Read and un d e r s t a n d t h e c o ntents of the Operator’s
Manual before starting and operating the aerator. Become familiar with the controls and know how to stop the
machine quickly. A replacement Operator’s Manual is
available on the Internet at www.Toro.com or by sending
the complete model and serial number to:
The Toro Company
Attn. Technical Publications
8111 Lyndale Avenue South
Bloomington, Minnesota 55420−1196
2. Keep all shields, safety devices and decals in place.
If a shield, safety device or decal is defective, illegible
or damaged, repair or replace it before operating the
machine.
3. Make sure that the tractor is carefully selected to assure the best performance and safe operation of the
ProCore aerator.
4. Make sure that operator is familiar with safe tractor
operation.
5. Tighten any loose nuts, bolts or screws to ensure
machine is in safe operating condition.

the aerator coring head when it is engaged.
2. Before starting the engine on the tractor:
A. Apply the parking brake.
B. Make sure traction lever or transmission is in neu-
tral and PTO is disengaged.
C. Refer t o Tractor Operator’s Manual for safe start-
ing procedures.
3. Do not run tractor engine in a confined area without
adequate ventilation. Exhaust fumes are hazardous
and could possibly be deadly.
4. If abnormal vibration is detected, disengage PTO
and stop tractor immediately. Determine source of
vibration and correct problem(s) before resuming the
use of aerator.
5. While operating, the combination of the tractor and
the ProCore aerator may exceed noise levels of
85dB(A) at the operator position. Hearing protection is
recommended for prolonged exposure to reduce the potential of permanent hearing damage.
IMPORTANT: Never operate aerator without tine
heads installed.
IMPORTANT: Never operate the tractor PTO in excess of 540 RPM or damage to the aerator could occur.
6. Before leaving the operator’s position of the tractor:
A. Disengage PTO power to aerator and lower aera-
tor to the ground.
B. Apply parking brake on tractor. Stop engine and
remove key from ignition switch.
C. Wait for all moving parts to stop before leaving

disengage tractor PTO, position aerator on a level surface and lower aerator to the ground. Apply tractor parking brake, stop engine and remove key from the ignition
switch.
2. Make sure machine is in safe operating condition by
keeping all nuts, bolts and screws tight.
3. Use care when checking or servicing the coring
head: wear gloves and use caution.
4. Never step over the PTO shaft to reach other side o f
aerator. Walk around the machine instead.
5. Before disconnecting aerator from tractor, install
storage stand to aerator hitch frame and park aerator on
a hard, level surface.
6. After servicing the aerator, be sure that all guards
and covers are properly installed and that the rear hood
is secured shut.
7. At the time of manufacture, the machine conformed
to all applicable safety standards. To assure optimum
performance and continued safety certification of the
machine, use genuine Toro replacement parts and accessories. Replacement parts and accessories made
by other manufacturers may result in non-conformance
with the safety standards, and the warranty may be
voided.
8. If major repairs are ever needed or assistance is de-
sired, contact an Authorized Toro Distributor.

Torque Specifications
Recommended fastener torque values are listed in the
following tables. For critical applications, as determined
by Toro, either the recommended torque or a torque that
is unique to the application is clearly identified and specified in this Service Manual.
These Torque Specifications for the installation and
tightening of fasteners shall apply to all fasteners which
do not have a specific requirement identified in this Service Manual. The following factors shall be considered
when applying torque: cleanliness of the fastener, use
of a thread sealant (e.g. Loctite), degree of lubrication
on the fastener, presence of a prevailing torque feature,
hardness of the surface underneath the fastener’s head
or similar condition which affects the installation.
Fastener Identification
As noted in the following tables, torque values should be
reduced by 25% for lubricated fasteners to achieve
the similar stress as a dry fastener. Torque values may
also have to be reduced when the fastener is threaded
into aluminum or brass. The specific torque value
should be determined based on the aluminum or brass
material strength, fastener size, length of thread engagement, etc.
The standard method of verifying torque shall be performed by marking a line on the fastener (head or nut)
and mating part, then back off fastener 1/4 of a turn.
Measure the torque required to tighten the fastener until
the lines match up.
