MAINTENANCE
Main Conveyor Mat.
The Rubber Conveyor Mat has proven to work well in a
variety of conditions. It is the preferred choice of most
sod growers.
See page 6-03 for the installation of a new mat.
The Mat Drive is by Hydraulic Motor ‘
A ’ via Chain and
Sprockets ‘ B ’ to Conveyor Drive Shaft ‘ C ’.
The Mat Drive Sprockets ‘
D ’ run in slots in the mat.
The slots have replaceable Metal Clips ‘M’.
See page6-03 for Clip Replacement procedure.
To prevent premature/excessive wear the mat sprockets
must be ‘centered’ in the mat slots.
The ‘tracking ‘ of the mat square to the conveyor frame
is determined by the Crown Roller, see below.
The Mat Drive Shaft Alignment Bolts ‘
E ’, on both
sides of the conveyor frame, are set at the factory, and
should not require adjustment. (See page 6-04).
Crown Roller.
The Crown Roller, at the bottom end of the conveyor,
keeps the mat ‘tracking’ square on the conveyor.
The Roller Shaft is aligned in the frame with Taper
Wedges ‘
F ’, located at each Roller Shaft Bearing ‘ G ’.
See the following pages for the correct alignment
procedure.
IMPORTANT
The Crown Roller must be set so that the sod guide
bracket does not hit against the conveyor mat.
Initially position the Roller shaft at the mid-point of
adjustment, determined by the backstroke of the cutter
blade and with allowance for the thickness of the mat.
Also allow for some forward movement of the assembly
during final alignment.
Mat Tension Idler.
Tension on the Conveyor mat is maintained by adjustable
Tension Idlers ‘H’.
Chains on the Idler Arms ‘
J ’ are attached to tension springs.
Move the chain links to adjust the tension.
IMPORTANT
Do not allow the idler arm to approach an angle of 90
degrees to the frame as it will be pulled over center and
mat tension will be lost.
Mat Support. 4 inch Roller Drive.
The Mid-Idler Shaft Sprockets Assembly supports
the mat.
The Sprockets ‘
K ’ drive the 4 inch Feed Roller ‘ L ’.
