141/181 Series Rear Blade Introduction Section 2-2

INTRODUCTION

The 141/181 Series Blades are designed with care and built with quality materials by skilled

workers. Proper assembly, maintenance, and operating practices, as described in this man-

ual, will help the owner/operator get years of satisfactory service from the machine.

The purpose of this manual is to familiarize and instruct. The Assembly Section instructs

the owner/operator in the correct assembly of the Blade using standard and optional equip-

ment.

Careful use and timely service saves extensive repairs and costly downtime losses. The

Operation and Maintenance Sections of the manual train the owner/operator how to work

the Blade correctly and attend to appropriate maintenance. The Troubleshooting Guide

helps diagnose difficulties and offers solution to the problems.

Safety is of primary importance to the owner/operator and to the manufacturer. The first

section of this manual includes a list of Safety Messages, that, if followed, will help protect

the operator and bystanders from injury or death. Many of the Safety Messages will be re-

peated throughout the manual. The owner/operator/dealer should know these Safety Mes-

sages before assembly and be aware of the hazards of operating this blade during

assembly, use, and maintenance. The Safety Alert Symbol combined with a Signal Word,

as seen below, is intended to warn the owner/operator of impending hazards and the degree

of possible injury faced when operating this machine.

141/181 Series Rear Blade Introduction Section 2-3

INTRODUCTION

The 141 and 181 Series Blades are available in widths of 8' and 9' for the 141 Series and

9’ and 10’ for the 181 Series. These blades feature a heavy-duty CAT II-III three-point hitch

and quick-hitch. The 8’ and 9’ models of the 141 Series are rated for up to 140HP (2 WD)

& 110 HP (4WD) tractors. The 181 Series with 9’ or 10’ Blade are rated at 180HP (2WD)

and 140HP (4WD) tractors. The Blade is available with either hydraulic or manual mainframe

swing, moldboard angle, and moldboard tilt. The Blade can be offset a maximum of 35"

(141 Series) and 37” (181 Series) for working outside the dual wheels on larger horsepower

tractors. The 4" diameter solid steel kingpin (141 Series) and 5” solid steel kingpin (181 Se-

ries) with boxed section reinforced 1/2” x 18" moldboards, and the superior strength of the

mainframes ensure dependability. The bolt-on gauge wheels are an excellent feature in

helping to control the cutting depth. This is especially critical when trying to leave a smooth

finish. Skid shoes, quick-tach end plates.

At least 20% of the tractor’s weight must be on the front tires with the im-

plement lifted to provide adequate traction for safe steering under good

conditions. Slow down on hills, rough terrain, and curves.

Front and rear, and left and right are determined by the normal direction of travel (the same

as on your automobile).
