Adjusting The Side Shield; Replacing The Turf Guards; Coring Head Timing - Toro ProCore 864 Operator's Manual

Adjusting the Side Shield

The coring head side shields should be adjusted so
that the bottom rides between 25 to 38 mm (1 to 1-1/2
inches) from the turf while aerating.
1. Loosen the bolts and nuts securing the side
shield to frame (Figure
Figure 39
1. Side shield
2. Adjust the shield up or down and tighten the
nuts.

Replacing the Turf Guards

All turf guards (Figure 40) should be replaced if broken
or worn to less than 1/4 inch thickness. Broken turf
guards can catch and tear turf, creating undesirable
damage.

Coring Head Timing

The unitized coring head design of the machine
provides industry-leading smooth operation while
taking out the guesswork of timing.
ProCore 864 (Figure
Each pair of crank arms joined through a bearing
housing are timed 180 degrees apart (i.e. arm
positions 1-2, 3-4, 5-6, 7-8). The adjacent pairs are all
set with the same timing whereas the later pair lags
by 120 degrees. The same pair of coupling castings
are used between all adjacent pairs (i.e. coupling
positions 2-3, 4-5, 6-7). To further reduce operating
vibration, 2 counter weights are added at the #1
position on the pulley and the #8 position.
Note:
The numbers cast into the crank arms do not
align with the raised indicator mark on the bearing
housings for the ProCore 864.
ProCore 1298 (Figure
This unit is comprised of 2 independent coring heads
with 6 arms each. The timing of either coring head
is not dependent on the adjacent coring head. The
timing marks are easily identified by the numbers cast
into the crank arm castings and the raised locator on
the bearing housings. The #1 arm always starts with
the drive pulley.
