Protecting yourself and those around you

This is a high-powered machine, with moving parts operating with high energy at high speeds. You must operate the machine safely. Unsafe operation can create a number of hazards for you, as well as anyone else in the nearby area. Always take the following precautions when using this machine:

 Keep in mind that the operator or user is responsible for accidents or hazards occurring to other people, their property, and

themselves.

 Always wear protective goggles or safety glasses with side shields while trimming to protect your eyes from possible thrown

debris.

 Avoid wearing loose clothing or jewelry, which can catch on the machine’s moving parts.  We recommend wearing gloves while using this machine. Be sure your gloves fit properly and do not have loose cuffs or

drawstrings.

 Wear shoes with non-slip treads when using your DR 3-POINT HITCH TRIMMER/MOWER. If you have safety shoes, we

recommend wearing them. Do not use the machine while barefoot or wearing sandals with exposed toes or heels.

 Wear long pants while operating the DR 3-POINT HITCH TRIMMER/MOWER.  Use ear protectors or ear plugs rated for at least 20 dba to protect your hearing.  Keep bystanders at least 100 feet away from your work area at all times. The tips of the cutting cords on the DR 3-POINT

HITCH TRIMMER/MOWER can throw sticks, small stones, gravel, and bits of debris over long distances at great velocity. Do not travel over loose materials such as gravel or mulch with the trimmer head spinning. Doing so could cause personal injury or property damage from thrown objects. Disengage the PTO Shaft to stop the spinning cords and shut off the Tractor engine when another person or pet approaches.

 Never tamper with safety devices. Check their proper operation regularly.  Never operate the machine when under the influence of alcohol, drugs, or medication.

Operating the Trimmer/Mower Safely

 Do not have the Trimmer engaged or resting on the ground when backing up. The machine is designed to trim and roll on

the Wheel in the forward direction only. Trimming or rolling on the Wheel in the reverse direction could damage the machine and is not covered by the Warranty.

 Know how to stop the Trimmer quickly by disengaging the PTO Shaft and shutting down the tractor.  Never allow people who are unfamiliar with these instructions to use the DR 3-POINT HITCH TRIMMER/MOWER. Allow

only responsible individuals who are familiar with these rules of safe operation to use your machine.

 Do not exceed 2 mph when trimming to allow proper cutting and discharge of material.  Do not exceed 7 mph when transporting to prevent damage to the machine.  Operating your 3point trimmer with the head misaligned with the ground can result in poor cut quality, pivoting problems,

scalping during cutting, wear on your equipment, and damage to the cutting cord

 Never place your hands, feet, or any part of your body on or under the mower deck in the path of the spinning cords, belt,

pulleys, or near the discharge opening while the tractor is running. Keep area of discharge clear of people, animals, buildings, glass, or anything else that will obstruct clear discharge, cause injury, or damage.

 Your DR 3-POINT HITCH TRIMMER/MOWER is a powerful tool, not a plaything. Exercise extreme caution at all times. The

design of your machine is for trimming and mowing grass, weeds, and other growth as specified in this manual. Do not use it for any other purpose.

 Whenever you leave the operating position to make adjustments, change cords or if you have to remove grass or debris from

the underside of the deck, always disengage PTO, shut down the Tractor Engine, remove the Key, wait for all moving parts to come to a complete stop, disconnect the PTO shaft from the Tractor, then wait five minutes before performing any maintenance procedure or inspection on the Trimmer.

3-POINT HITCH TRIMMER/MOWER

Operating the Mower Safely (continued)

 Be mindful of roll over hazards, changes in terrain, slopes, or wet conditions. Use care when backing up.  Stop the cutting cords when crossing gravel drives, walks, or roads.  Never, under any conditions, remove, bend, cut, fit, weld, or otherwise alter standard parts on the DR 3-POINT HITCH

TRIMMER/MOWER. This includes all shields and guards. Modifications to your machine could cause personal injuries and property damage and will void your warranty.

 If the cutting cords strike a foreign object or if your machine should start making an unusual noise or vibration, disengage

PTO, shut down the Tractor Engine, remove the Key, wait for all moving parts to come to a complete stop, disconnect the PTO shaft from the Tractor, then wait five minutes before inspection. Vibration is generally a warning of trouble. Clean and repair and/or replace damaged parts.

 While using the DR 3-POINT HITCH TRIMMER/MOWER, do not hurry or take things for granted. When in doubt about the

equipment or your surroundings, stop the machine and take the time to look things over. Make sure that you have 100% control of the Trimmer at all times.

 Watch for traffic when mowing near roadways.  Use the machine only in daylight.  Be cautious when using your DR 3-POINT HITCH TRIMMER/MOWER around fencing, wires, ropes, and hoses. It is possible

that these and other debris can become wound around the Cord Head of the machine, potentially damaging the bearings or injuring you.

 Do not operate the DR 3-POINT HITCH TRIMMER/MOWER on slopes greater than is recommended in your Tractor manual.  Keep all nuts and bolts tight and keep the equipment in good operating condition.

Calculating length of PTO Shaft needed

The PTO Shaft provided with your Trimmer is 32" overall compressed length and will work “as is” for most applications. Before you install the PTO Shaft it is good practice to run through the following dimension checks to calculate optimum PTO Shaft length to determine if modifications are needed.

Without the PTO Shaft installed, use the table below to record the dimensions as outlined in the following steps.

Wheel

Figure 6

Gearbox Guar

Remove Hardware

Figure 7

Note: Install the Locking Bolt as described in the paragraph “INSTALLING THE LOCKING BOLT FOR PARALLEL TRIMMING/MOWING” in the “Preparing the Trimmer/Mower for Trimming” section in Chapter 3.

1. Remove the front Bolt, Washers and Locknut from the Gearbox Guard with

two 11/16" Wrenches (Figure 7).

2. Slightly loosen the rear Bolt, Washers and Locknut of the Gearbox Guard

with two 11/16" Wrenches.

3. Rotate the Gearbox Guard up away from the Gearbox Shaft.

4. Lower the Trimmer all the way to the ground in the operating position

Measure Distance

Figure 8

8 DR

3-POINT HITCH TRIMMER/MOWER

(Figure 8). Measure from the end of the Tractor Spline Shaft to the end of the Trimmer Gearbox Shaft and record this dimension in the “ON GROUND” row of the table above.

5. Raise the Trimmer up until the Tractor PTO Spline and Trimmer Gearbox Shaft are parallel with each other. Measure from the

end of the Tractor Spline Shaft to the end of the Trimmer Gearbox Shaft and record this dimension in the “SHAFTS LEVEL” row of the table above.

6. Raise the Trimmer up as far as it will go. Measure from the end of the Tractor Spline Shaft to the end of the Trimmer Gearbox

Shaft and record this dimension in the “FULLY RAISED” row of the table above.

Note: If your longest measurement exceeds 37" you will require a longer PTO Shaft. Do not proceed with installation until you have a

longer PTO Shaft. If you have any questions, please visit us at www.DRpower.com or call 1-800-DR-OWNER (376-9637).

7. Take the shortest recorded measurement you wrote in the table and add 2".

8. Take that number and subtract it from 32" (overall compressed length of the supplied PTO Shaft).

9. This final number is the length that you will need to cut off of the PTO Shaft for it to fit properly to your Tractor.

EXAMPLE:

Let’s assume the shortest center-to-center measurement in the table is 27".

 27 + 2 = 29 (step 4 above)  32 – 29 = 3 (step 5 above)  You would be required to cut 3" off both halves of the PTO Shaft and 3" off the Guard.

Note: If you end up with 0" or a negative number, then no changes are needed until you reach a maximum long measurement of 37" as

indicated on previous page.

Modifying the PTO Shaft-if required

If you have determined in the previous steps that the PTO Shaft is too long for your set up, shorten the Shaft as follows:

Tools and Supplies Needed:

 Hacksaw  Bench Vise  Tape Measure  File  General purpose Lithium Grease

Note: Your actual PTO Shaft may look different than the one shown in these steps

but the procedures are the same.

1. Separate the PTO Shaft Halves by pulling them apart.

2. Separate the Guards from the PTO Shaft Halves by inserting a flat tip

screwdriver into the Bearing Tab Slots as you pull down on the Safety Guard to release the Safety Guard from the Shaft (Figure 9).

3. Measure and cut the ends of both Guards the required amount (Figure 10).

Note: If you put the Guards in a vise to hold them, be careful not to clamp it too

tight because it could crack the plastic.

4. Measure and cut each Shaft Tubes to the required length using the hacksaw

(Figure 11).

5. File or sand any burrs from the Shaft ends (Figure 12).

6. Grease both Shaft Tubes and under the Bearing Rings of each Shaft (Figure

13).

7. Insert the Shaft Halves into the Guards making sure that the Bearing Ring

Slot lines up with the Tab on the inside of the Guards for proper installation (Figure 14).

8. Slide the two PTO Shaft Halves together.

Note: When inserting one half of the PTO Shaft to the other you must line up the splines correctly (two pointed splines and one flat spline).

Continue to the following section to attach the PTO Shaft to the Tractor and Trimmer.

Attaching the PTO Shaft to the Tractor and Trimmer

Note: The PTO Driveshaft provided with your new machine is sized to fit a standard

category 1 PTO (1-3/8" DIA. x 6" Spline).

The PTO Spline Shaft on the tractor that is to use this machine must rotate clockwise when viewing the PTO from the rear of the tractor. If the PTO rotates counterclockwise, you must have your tractor modified by installing a gearbox to reverse the direction of rotation.

The length of the PTO Driveshaft that is included with your new machine will work in most instances but may need to be modified. See “Calculating Length of PTO Shaft needed” for checking the PTO Shaft length desired and then “Modifying the PTO Shaft if required” instructions if the PTO Shaft is too long.

You must install the Key supplied in the Product Package where the PTO shaft attaches to the Trimmer Gearbox. Failure to install the Key will result in damage to the machine and is not covered under warranty.

Tools Needed:

 4mm Allen Wrench

1. Open the Gearbox Guard as described on page 8.

2. Insert the Key into the Trimmer Gearbox Shaft (Figure 15).

3. Align the Key Slot of the PTO Shaft with the Key in the Shaft and slide it

onto the Shaft (Figure 16).

Note: Do not allow the PTO Shaft to contact the Gearbox. The Gearbox Shaft end

should be flush with the inside of the U-Joint.

4. Secure the PTO Shaft by tightening the Set Screw with a 4mm Allen Wrench.

Note: If you plan to leave the Trimmer attached to the Tractor for extended periods,

apply thread lock to the Set Screw to help secure it in place.

5. Push in the Spring Pin at the end of the PTO Shaft and slide it onto the

Tractor Spline (Figure 17). When the PTO Shaft is started on the Tractor Spline Shaft, release the Pin and continue to push the PTO Shaft until the Spring Pin locks into the Groove of the Tractor Spline.

6. Attach the Safety Chain of the PTO Shaft around a solid area of the 3-Point

Bracket with the Chain ends attached to both ends of the PTO Shaft Guard (Figure 18). Make sure the Chain has enough slack in the full range of the Tractor 3-Point Arm travel.

7. Lower the Gearbox Guard and install the front Bolt, Washers and Locknut

with two 11/16" Wrenches (Figure 19).

8. Tighten the rear Gearbox Guard hardware with two 11/16" Wrenches.

Installing Trimmer Cords

Note: Cutting height adjustments can be made as you learn the trimming

characteristics of the machine in the “Operating the DR 3-Point Hitch Trimmer/Mower” in the next Chapter.

Always make sure to install all four Trimmer Cords and ensure they are the same length. Not having all four Cords installed and/or at the same length will cause excessive vibration and could damage the machine.

1. Insert the end of a Trimmer Cord into the inlet hole (larger slotted cutout)

push it in until the end protrudes out the other side approximately 1/2" (Figure 20).

2. Turn the Cord Head 90 degrees and repeat the installation until all Cords

are installed.

Note: The Cord can only move through the Cord Head in one direction. To remove

it you must pull it from the other side of the Holder (where the 1/2" end is).

Running the trimmer without all four cords installed or cords of unequal length can cause excessive vibration and may damage the machine.

Preparing the Trimmer/Mower for Trimming

The characteristics of cutting height and quality is controlled by the position of the Trimmer Cords, location of Locking Bolt, Wheel Spacer arrangement and height of Tractor PTO lift Arms. It takes time and practice to learn what the best combinations of settings for different conditions are.

INSTALLING THE LOCKING BOLT FOR PARALLEL TRIMMING/MOWING (terrain that is level with Tractor Wheels)

1. Install the Bolt into the right side “holes” location through the 3-Point

Bracket and Trimmer Bracket (Figure 25).

2. Secure the Bolt with the Wing Nut.

INSTALLING THE PIVOT BOLT FOR PIVOT TRIMMING/MOWING (terrain that is higher or lower than Tractor Wheels such as ditches)

1. Install the Bolt into the left side “slots” location through the 3-Point Bracket

and Trimmer Bracket (Figure 26).

2. Secure the Bolt with the Wing Nut.

Checking 3-Point Bracket to PTO Shaft clearance

Observe the Trimmer as it is lifted to ensure that the 3-Point Bracket does not contact the PTO Shaft. If they do touch, the Tractor may have a setting to limit the distance it is lifted off the ground to prevent contact. See your Tractor user manual for details of Tractor settings.

2. Adjust the Spacers as desired with some under and some above the Support

on the Shaft.

3. Reinstall Wheel Assembly, Spacers and Hitch Clip.

Note: More Spacers under the Support will lower the Wheel and set the Trimmer

Head Higher. More Spacers on top of the Support will raise the Wheel and set the Trimmer Head Lower.

Engaging the Trimmer Head

1. Ensure that the Trimmer is lowered to the ground and all Guards are in

place and properly secured before using.

2. Set Tractor throttle at IDLE and engage the PTO.

3. Increase Tractor throttle to the RPM’s required to obtain 540 PTO speed.

Cord Tips

We ship two (2) thicknesses of Cutting Cord with your DR 3-POINT HITCH TRIMMER/MOWER.

The Cords are Blue (175-mil) and Green (155-mil). Because conditions and vegetation vary so much, you should experiment with Cord weights (diameters) to discover what works best for your particular mowing and trimming situations. Here are a few things to keep in mind:

 If you buy Cutting Cord in rolls, cut it in 13" lengths. Cut them at an angle so they will be easier to install.  Soak your Cutting Cord in a bucket of room temperature water for a few days before use to make it more pliable. Storing the

Cord in a plastic bag with a damp sponge or cloth will help keep it pliable

 Cord life depends on trimming conditions. Replace Cords when they become broken or frayed.  The smallest diameter Cord capable of cutting the material at hand usually provides the best grass trimming performance.

When you need more strength for thicker growth such as berry canes, brambles, thistles, or ragweed, you may want to use the 175-mil Cord.

 Ease the ends of the Cord into heavy growth and move slowly through thick growth. If there are woody weeds in the material

you are cutting, the cutting Cords may wrap around the stalks they cannot cut, and pull away from the Trimmer Head.

 If the Cord breaks off flush at the Cord Head, use needle nose pliers to pull out the old Cord.  UV light can degrade cord, store out of direct sunlight.

Preparing the Trimmer/Mower for Transport

Always disengage the PTO Shaft before lifting the Trimmer off the ground or transporting the Trimmer to prevent injury or damage to the machine.

1. On the right hand side of the machine (trimmer head side), align the holes

of the Trimmer with the holes in the 3-Point Hitch Bracket. Insert the Locking Bolt through the holes (Figure 28).

2. Secure the Bolt with the Wing Nut.

Note: Observe the Trimmer as it is lifted to ensure that the 3-Point Bracket does not contact the PTO Shaft. If they do touch, the Tractor may have a setting to limit the distance it is lifted off the ground to prevent contact. See your Tractor user manual

for details of Tractor settings.

3. Lift the Trimmer off the ground with the Tractor 3-Point Hitch before

transporting to prevent hitting any obstacles.

Obstacles

Dealing with obstacles in the terrain is easy with your new DR 3-POINT HITCH TRIMMER/MOWER. The following section explains how to approach most common obstacles.

 Always check your work area before trimming and remove any debris that

Optimum Impact Zone Label

might tangle or damage the machine.

 Approach obstacles (fence posts etc) so the impact zone will be within the

area of the Optimum Impact Zone Label (Figure 29). This will ensure the best spring action and trimming coverage around the obstacle.

 If you do run into debris and the Trimmer becomes tangled, disengage PTO, shut down the Tractor Engine, remove the Key,

wait for all moving parts to come to a complete stop, then wait five minutes for parts to cool before attempting to untangle the machine.

 Never Trim or let the Wheel rest on the ground with the Tractor in reverse.

Heavy Growth

 Take your time in heavy growth.  If the machine cannot do it all in one pass, overlap half of the cutting swath.  Ease the DR 3-POINT HITCH TRIMMER/MOWER into denser growth. If the material is too tough or woody to cut, the Cutting

Cords will wrap around it, wear down, or even break off.

Tip: Use the “two pass”, one half overlap method, whenever possible.

Wet Conditions

Because there is no housing to restrict the flow of cut material, you can also use your DR 3-POINT HITCH TRIMMER/MOWER to mow wet or heavy growth. You can use the Trimmer in damp conditions, after a rain, or in the early morning dew without clogging or stalling. You can also mow wet areas such as ditches and around ponds.

Slopes

Refer to your Tractor Users Manual for slope safety information and operation guidelines.

Windrows

The DR 3-POINT HITCH TRIMMER/MOWER Cutting Cords cut even tall grass in just one pass, so you can collect clippings and leaves for mulch without raking. The machine ejects cut material to its right side, so you can use it like a lawn broom to make windrows for easy clean-up.

Firebreaks

Use your Trimmer as a labor saving tool to cut material when creating firebreaks.

Chapter 4: Maintaining The DR 3-POINT HITCH TRIMMER/MOWER

Regular maintenance is the way to ensure the best performance and long life of your machine. Please refer to this manual for maintenance procedures.

Disengage PTO, shut down the Tractor Engine, remove the Key, wait for all moving parts to come to a complete stop, disconnect the PTO shaft from the Tractor, then wait five minutes before performing any maintenance procedure or inspection on the Trimmer.

Regular Maintenance Checklist

Note: Consider that the service intervals shown are the maximum under normal operating conditions. Increase frequencies under

extremely dirty or dusty conditions. See the Owners Manual that came with the Tractor and with the PTO Shaft for Specific Tractor and PTO Shaft maintenance.

Maintenance position

Many maintenance procedures can be performed easier by positioning the Trimmer in an upright “maintenance” position. This position is for maintenance purposes only. Do not transport or operate the Trimmer in the upright position.

 Two people are required when setting the Trimmer Body to the

maintenance position. One person must steady the Trimmer as the other installs the Bolt. Do not allow the Trimmer Body to go beyond vertical and fall in the opposite direction without the Bolt in place as this could cause injury to you or damage the Trimmer.

 Never transport the Trimmer in the “Maintenance” position. This could

damage the machine and is not covered by the Warranty.

1. Remove the Bolt and Wing Nut that is holding the Trimmer in the trimming

operating positions.

2. Lift the Trimmer Body up to a vertical position. With the head of the Bolt

facing the Tractor, install the Bolt all the way into the transport hole of the 3Point Bracket (Figure 30).

3. Let the Trimmer Mounting Bracket rest against the Bolt to hold it in the

vertical (maintenance) position.
