DESCRIPTION

1-1 Introduction

Your grass 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 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 draws grass clippings from the discharge 
area of the cutting deck back to the (2) - 4 cubic foot 
collection bags P#(G0013-L) at the rear portion of the 
mower frame. The operator can engage the blower with 
a toggle switch mounted on the control panel to the right 
of the operator. Once the bags are full with clippings, 
they can be easily released for dumping.
