The 141/181 Series Blades are designed with care and built with quality materials by skilledworkers. 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 instructsthe 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. TheOperation and Maintenance Sections of the manual train the owner/operator how to workthe Blade correctly and attend to appropriate maintenance. The Troubleshooting Guidehelps diagnose difficulties and offers solution to the problems.

Safety is of primary importance to the owner/operator and to the manufacturer. The firstsection of this manual includes a list of Safety Messages, that, if followed, will help protectthe 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 duringassembly, 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 degreeof possible injury faced when operating this machine.

The 141 and 181 Series Blades are available in widths of 8' and 9' for the 141 Series and9’ and 10’ for the 181 Series. These blades feature a heavy-duty CAT II-III three-point hitchand 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 mainframeswing, 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 horsepowertractors. 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 themainframes ensure dependability. The bolt-on gauge wheels are an excellent feature inhelping to control the cutting depth. This is especially critical when trying to leave a smoothfinish. 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 goodconditions. Slow down on hills, rough terrain, and curves.

Front and rear, and left and right are determined by the normal direction of travel (the sameas on your automobile).

The 141 and 181 Series Blades are shipped partially assembled from the factory. Each blade will be shippedon two pallets. The first pallet will contain the A-frame, Back Bone and Swivel Tube assemblies. The secondpallet contains the Moldboard assembly. The pins and fasteners used to assemble the blade will be installedat the factory. The removal and reinstallation of these pins and fasteners is required to complete assembly.

MOLDBOARD ASSEMBLY

1. Remove the Tilt Pin (3) and install the Swivel tube (1) into the Moldboard assembly (2).

2. Replace the Tilt Pin (3) and secure with the supplied fasteners.

3. Attach your 8” Pin jack (4) or cylinder with the supplied 1” cylinder pins (7, 8) and secure with cotter pins.

4. Make sure your Pin Jack or Cylinder is fixed to the center positon so the Swivel Tube is 90° from theMoldboard. If cylinder is used, attach rod end to Moldboard (2).

• Front End Weight As needed to maintain 20% weight on front axle

Tractor HorsepowerThe power required to operate a blade is determined by the tractor PTO horsepower. For most operating condi-tions, the 141 Series rear blade requires a tractor with a maximum of 140 HP for 8’ & 9’ on 2 wheel drive tractorsand a maximum of 110 HP for 8’ & 9’ on 4 wheel drive Tractors. The 181 Series rear blade requires a tractor witha maximum of 181 HP for 9’ & 10’ on 2 wheel drive tractors and a maximum of 140 HP for 9’ & 10’ on 4 wheeldrive tractors. Operating the blade with a tractor that does not have adequate power may damage the tractor en-gine.Exceeding the recommended horsepower may cause blade damage by over powering the unit in heavy op-erating conditions.

Tractor 3-Point HitchThe tractor 3-point hitch must be rated to lift at least 1145lbs. for the 8’ and 1170 lbs. for the 9’ on the 141 SeriesBlade and 1586 lbs. for the 9’ and 1613 lbs. on the181 Se-ries Blade.

The 141 and 181 Series can attach to tractor’s with eithera CAT II or III hitch. Refer to the tractor operator’s manualfor the category of the tractor used. If the hitch does notconform to the ASABE CAT II or III dimensions, the blademay not fit or raise properly. Consult an authorized dealerfor possible modification procedures to mount nonconform-ing hitches.

Use the correct hitch pins for the hitch category being used.For a Cat II hitch, 1-1/8” lower and a 1” upper diameter hitchpins are used and Cat III hitches require 1-7/16” lower anda 1-1/4” upper diameter hitch pins.

Front End WeightA minimum of 20% total tractor weight must be maintained on the tractor front end at all times. Frontend weight is critical to maintain steering control and to prevent the tractor from rearing up while driv-ing. If the front end is too light, add weight until a minimum of 20% total weight is reached on thefront tires. Front weights and weight carriers can be purchased through an authorized tractor dealer-ship. OPS-U- 0005

General Maintenance

1. Grease all grease fittings and lubrication points before each use.2. Inspect the implement for any worn or damaged parts and replace with a genuine Bush

Hog part.3. Make sure all safety decals are intact and legible.4. Inspect unit for cracks and chips and repair if necessary. Consult your Bush Hog dealer

before any repair is made. Any unauthorized repairs will void the warranty.5. Replace eccessively worn Grader Blades. A badly worn edge increases the strain on

the blade and the tractor and reduces efficiency.6. Check all bolt and nuts to insure they are properly torque. Consult the torque chart

found in this manual for torque values.

Proper Torque Chart for Fasteners

The chart lists the correct tightening torque for fasteners. When bolts are to be tightenedor replaced, refer to this chart to determine the grade of bolts and the proper torque exceptwhen specific torque values are assigned in manual text.

RECOMMENDED TORQUE IN FOOT POUNDS UNLESS OTHERWISE STATED IN THEMANUAL

NOTE: These values apply to fasteners as received from supplier, dry or when lubricatedwith normal engine oil.They do not apply if special graphite or molydisulphide greases or other extreme pressurelubricants are used.This applies to both UNF fine and UNC coarse threads.
