1-1 Introduction
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.
NOTE: all references made to right, left, front, rear, top
or bottom are as viewed from the normal operator’s
position on the mower.
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.

INSTALLATION FOR USE
2-1 Preparation Of Mower
Carefully dismantle wooden shipping crate from around
the components. Cut retaining straps and separate the
parts. The collection system will have various parts
located inside. Remove and sort all parts for easy
identification.
NOTE: Before each step of assembly it will help to study
the exploded drawings on pages 16-18.
NOTE: Engine pulley installation instructions are for
PTO models only.
From the underside of the engine remove the bolt and
bushing from the electric clutch assembly. Replace these
parts with the engine pulley assembly #20 P#(A1798),
7/16” lock washer P#(K0140), and 7/16”-20 x 3-3/4”
HHCS P#(K0359).
The added pulley will power the collection system. Note

toward the engine (Figure 2-1a). Torque the bolt to 55
ft./lbs.
NOTE: It may be necessary to remove the drive belt
from the deck pulley before removing the bushing. Refer
to your Bob-Cat owner’s manual.

Connect the kevlar cord belt A57K P#(M0256) from the
engine pulley to the lower gear box pulley as shown in
Figure 2-11d.
To tension the drive belt, turn the adjustment bolt
clockwise (Figure 211e) until there is 1” of deflection,
with 10-11 lbs. of pressure, at the center of the belt
between the engine pulley and the gear box pulley.
Once the correct tension of the belt is achieved, tighten
the (4) bolts that secure the gear box assembly. Refer to

2-12 Cam Assembly Adjustment
PTO MODELS ONLY
The cam assembly P#(A0422), which controls the
blower belt tension, comes from the factory pre-adjusted.
If the belt is too tight or becomes too loose, remove the
hair pin clip P#(K0099) from the belt tension rod
P#(K0326) and pull the “L” end of the rod out of it’s hole
in the cam assembly. The tension rod may then be
screwed out to tighten the belt or screwed in to loosen
the belt. Replace the “L” end into the top hole in the cam
and replace the hair pin clip. Adjust the cam stop bolt
P#(K1159) to allow the cam to rotate slightly over center
when the blower is disengaged (Figure 2-12).
2-13 Outer Engine Mount Tube
Installation
Secure the outer engine mount tube P#(B1117) to the
rear frame bracket using (2) 3/8”-16 u-bolts P#(K1119)
and (4) 3/8”-16 nylon flange locknuts P#(K2038). Leave
the locknuts finger tight until the blower assembly has
been installed. Refer to Figure 2-13.
2-14 Engine Mount Arm Assembly
Installation
Insert the engine mount arm assembly P#(A1824) into
the end of the outer engine mount tube and secure using
(1) detent pin P#(J0248). Refer to Figure 2-13.
2-15 Engine/Blower/Blade Assembly
Installation
Place the engine blower blade assembly on top of the
engine mount arm. Secure the assembly using (4) 5/16”-
18 x 1-1/2” HHCS P#(K1157) and (4) 5/16”-18 nylon
flange lock nuts P#(K2516). Refer to Figure 2-15. Adjust
the position of the blower assembly by sliding the engine
mount tubes left or right. There should be a minimum of
1” clearance between the blower housing and the rear
tire. Tighten all hardware in Section 2-13.
2-16 Blower Cone Installation
Thread (1) 5/16”-18 jam nut P#(K0120) onto each end of
(2) 5/16”-18 x 2-1/2” HHCS P#(K0125). Now partially
thread the bolts into each of the two tabs located on the
blower housing. Place blower cone so the two tabs line
up with the bolts then tighten completely. See Figure 2-
16.

9Taper-Lock Bushing
Enlarged View
Tips on removing impeller blade;
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.
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.
2-17 Impeller Blade
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 2-17.
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 2-17. 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.
