1-1 Introduction
NOTE: all references made to right, left, front, rear, top
or bottom are as viewed from the normal operator’s
position on the mower.
We are pleased to have you as a PECO customer. Your
collection system has been designed to give you a low
maintenance, simple, and effective way to collect the
grass clippings from your mower. This manual is
provided to give you the necessary instructions to
properly mount and operate the collection system on
your mower. Please read this manual thoroughly.
Understand what each control is for and how to use it.
Observe all safety decal precautions on the machine and
noted throughout the manual.
1-2 Description
The grass collection system is designed for turf
maintenance where there is a need to collect the grass
clippings as the mower cuts the turf. It is also used for
picking up leaves and in pre-season and post-season
clean-up. The blower, mounted on the right side of the
unit, uses a belt and gearbox system from the engine
PTO shaft. Drive train protection comes through belt
slippage. The blower is also available with an external
engine option of 5.5HP or 6.5HP. The blower draws
grass clippings from the discharge area of the cutter
deck back to the 12 cubic foot aluminum box at the rear
portion of the mower frame. The operator can engage
the blower with a push of the over-center linkage on the
right side of the unit, or starting the external engine.
Once the bags are full with clippings, they can be
released to make for easy dumping.

To Replace: First, place the impeller blade (#1) over the
drive shaft (#13). Next, slide the taper-lock bushing (#9)
on to the drive shaft and into the impeller blade, aligning
the non-threaded holes (#14) of the taper-lock bushing
to the threaded holes of the impeller blade. Then, fasten
by using two 1/4”-20 x 1” HHCS (#10), one spacer
bushing (#8) one taper lock bushing washer (#7), and
one 3/8”-16 x 1-1/2” HHCS (#6). Torque all bolts to the
specifications located in the chart towards the back of
this manual. Last, rotate the impeller blade to ensure
that the blade is clear of contact on all sides of the
blower housing.
1 - Try carefully hitting the base of the impeller blade
(#1), between each vein (#12), with a rubber mallet to
loosen the taper-lock bushing hold.
2 - Spray break-free lubricant into the surrounding areas
of the taper-lock bushing (#9) and repeat Tip 1.
Tips on removing impeller blade;
To Remove: First, remove one 3/8”-16 x 1-1/2” HHCS
P#(K1211) (#6), one taper-lock bushing washer
P#(K0278) (#7) and one spacer bushing P#(S3242) (#8)
from the taper-lock bushing (#9). See Figure 2-24. Next,
remove two 1/4”-20 x 1” HHCS (#10) and place them
into the threaded holes (#11) of the taper-lock bushing
P#(S4302). Last, gradually thread each bolt evenly into
the taper-lock bushing, forcing the blade to break-away
from the taper-lock bushing.

Removal/Replacement
To gain impeller blade (#1) access, first remove the
blower cone (#2) from the blower housing, located on
the PTO assembly P#(A1821), by removing two blower
cone bolts and nuts (#3). Next, remove the blower
housing front (#4) by removing seven bolts and nuts (#5)
around the outer housing edge. Refer to Figure 2-24.

2-25 Weight Kit Installation
The collection system requires that a weight kit is
installed to the front of the mower to counter-balance the
weight of the collection system, when filled with debris.
NOTE: The (2) weight brackets are secured to the
caster supports first. Then the weight is added to the
weight brackets. It is recommended that two people
perform this procedure. If another person is not
available, use a rolling hydraulic floor jack to keep the
weight into position while you secure the weight to the
weight brackets
Locate the(2) weight brackets P#(B0026). Secure (1)
bracket to each front caster support, using (1) 3/8”-16 x
2-1/8” u-bolt P#(K1119) and (2) 3/8”-16 nylon flange lock
nuts P#(K2038) PER BRACKET. Position the weight
bracket as shown in Figure 2-25a. Insert the u-bolt from
the bottom of the caster support tube as shown in Figure
2-25b. Leave the hardware slightly loose until the weight
has been installed.
After the weight brackets have been secured to the
caster supports, place (1) weight bar P#(B0035) onto the
(2) weight brackets. It is strongly recommended that
someone assist you in lifting the weight bar into position.
Center the weight bar between the front casters. Secure
the weight bar to the weight bracket using (2) 1/2”-13 x
4-5/16” u-bolts P#(K0331) and (4) 1/2”-13 nylon flange
lock nuts P#(K2012). Tighten the weight bracket
hardware at this time. Refer to Figure 2-25c and 2-25d
for reference.

26c.
To install the throttle cable kit to the ROPS (roll over
protection system), place the 3/8” U-Bolt P#(K0136)
onto the ROPS with the threads facing the front of the
mower. Next slide on the throttle mount plate assembly
P#(A0666) with the rivets also facing toward the front of
the mower. Tighten the throttle mount plate assembly
securely to the ROPS using (2) 3/8”16 nylon flange lock
nuts P#(K2038) (Figure 2-26a). With the throttle cable
facing toward the engine/blower/blade assembly, place
the throttle base plate over the rivets, Slide the throttle
cable kit to the right, moving the smaller end of the slot
over the rivets. When positioned correctly, the throttle
spring plate will snap into place (Figure 2-26b).
2-26 Throttle Cable Installation
NOTE: Engine Driven Models Only
Secure the throttle cable to the blower housing assembly
using (1) J-Clip P#(K1455). Use the existing hardware
from the blower housing to secure the J-Clip, as shown
in Figure 2-26c.
To fasten the throttle cable end to the engine, place the
throttle control lever into the “stop” position. Rotate the
engine throttle lever to the “stop” position. Thread the
wire end of the throttle cable into the engine throttle lever
eyelet and tighten the screw. Fasten the throttle cable
sleeve to the clamp on the engine throttle (Figure 2-26d).
Rotate the throttle control lever into the “fast” position to
check for proper installation.
NOTE: Cable sleeve may need to be cut, depending on
the engine type. Once throttle cable is attached, lift the
plastic top assembly and make sure that the throttle
cable does not interfere with the movement of the plastic
top.
