Owners Manual - Operation


Read and Understand the Entire Operator's Manual Before Operating This Machine.

Always operate the TRENCH'N edge safety. Follow all safety warnings and wear the appropriate personal safety gear.

Operate only in the daylight. Do not operate when the grass is wet or when it is raining. Before Starting the engine, ensure that all guards and the reversible discharge chute are in place and securely mounted.

Be aware of the weight of the TRENCH'N edge. Know how to safely transport, lift and maneuver the machine. Before operating the trencher, check that no damage has occurred to the machine or the controls during transit to the worksite.


  • Safety First - Wear the appropriate safety gear. Gloves and safety shoes are recommended when operating the Trencher.
  • Check - The oil level in the engine crankcase. If necessary, fill the engine crankcase in accordance with the engine manufacturer's instructions. Engine is shipped from the factory without oil.
  • Grease - The fittings on the arbor main shaft bearings.
  • Use fresh fuel of a type and grade recommended by the engine manufacturer.
  • Inspect - The arbor teeth and the V-belt for damage.
  • Check - All guards are in place.
  • Check - The Trencher operates with vibration. Check and retighten nuts and screws frequently to ensure safe operation.

Always consult State and Local building codes to determine the proper size and depth of the trench required for the job. Building codes differ from state to state and locality to locality.


The trencher is operated by pulling it along a planned route. Plan your path before starting the trenching operation. Locate any above ground obstacles in your path and plan a safe route to avoid them. Mark a well defined, easy to follow path. For safety reasons, plan your route to avoid having to pull the trencher up any slopes. Do not trench on any steep slopes, maximum angle of operation is 15 degrees

Be familiar with the area you are going to trench. Watch out for large holes, drops, rises, slopes, and obstacles. Before trenching, make sure the area is clear of solid objects and debris that could be thrown by the machine or damage the machine. Plan to protect cars, windows, siding, etc. from any thrown object.

The trencher can trench up to 6" inches deep (12" deep for irrigation unit). Damage will occur to any buried object that the trenching arbor comes in contact with. Locate and mark the location of any buried objects that could be damaged by the trenching operation. When in doubt to the exact location of any buried utility or service line, always contact your local utility company before starting any trenching operation.

Before trenching, locate and mark any type of buried wires or cables:

  • Buried electrical service wires.
  • Buried cable TV service wires.
  • Buried telephone service wires.
  • Buried outdoor lighting wires.
  • Buried security system wires.
  • Buried electrical dog fence wires.
  • Buried intercom or music system wires.
  • Any other buried type of wires or cables.

Before trenching, locate and mark any type of buried gas or fuel lines:

  • Buried natural gas.
  • Buried Propane gas.
  • Buried Fuel oil lines.
  • Buried Home heating/cooking gas lines.
  • Any other type of buried gas or fuel lines.

Before trenching, locate and mark any type of buried irrigation:

  • Buried Irrigation sprinkler heads.
  • Buried Irrigation control boxes.
  • Buried Irrigation water supply and feeder lines.
  • Buried Irrigation drip feeder lines.
  • Buried Irrigation shut-off valves.
  • Any other type of irrigation lines or equipment.

Before trenching, locate and mark any type of buried irrigation:

  • Buried roof drain pipes
  • Buried drainage tiling pipes
  • Buried drainage collector boxes and catch basins.
  • Buried drainage access covers
  • Any other type of buried drainage lines or equipment.

Before trenching, locate and mark any type of sewer lines:

  • Buried sewer drain pipes
  • Buried sewer drain field tiling pipes
  • Buried sewer collector boxes and catch basins.
  • Buried drainage access covers and vent pipes.
  • Any other type of buried sewer lines or equipment.

The trencher can also cut or damage the roots of any shrub or planting around the work site. Always hand dig a small test area around any planting to determine if roots have spread into the planned work site.


Before starting the engine, place the discharge chute to the side of the machine you want the debris to be discharge from. Loosen the retaining hardware that holds the discharge chute to the arbor housing, remove the chute and turn to the discharge chute outlet to the side desired. Replace the chute to the arbor housing and securely reattach.


TO AVOID SERIOUS INJURY, Do Not Remove the Reversible Discharge Chute When the Engine is Running.

When the discharge cute is removed, the trenching arbor is exposed. Never operate the TRENCH'N edge without the discharge chute properly secured to the trenching arbor housing.

The debris discharge will be directed down out of the chute. For easy clean up of the worksite, place traps along the route to catch the discharge debris. During operation, always keep the tarps a safe distance from the machine so that they do not become caught in the trenching arbor.


Do Not Operate Without Guards In Place.


Never start the engine unless you are in the area being trenched. Move the TRENCH'N edge to the area being trenched and position machine at the start of the planned trenching route.

  1. Check that the clutch is in the "Disengaged" position (if unit is so equiped).
  2. Check that the trenching arbor does not touch the ground and that it has been raised to its highest position.
  3. Check that the fuel shut-off valve is in the "ON" position.
  4. Check that the engine "ON/OFF" switch is in the "ON" position.
  5. Set choke and throttle as needed. Pull starter rope to start engine.
  6. Reset throttle and choke as needed.


Keep Hands And Feet Away From Trenching Arbor. Never reach under the machine or into the discharge chute.

Always stay clear of the discharge chute when the engine is running or during operation. If the discharge chute becomes plugged during operation, disengage the clutch and STOP THE ENGINE before attempting to clean it out.

WET conditions can cause the chute to plug. Trench with caution.


Keep others, especially small children and pets, safely away from the area. Recommended safety radius from the machine is a minimum of 500 feet.

Never trench by pushing the machine, always pull the TRENCH'N edge. Avoid sudden stops and starts, operate in a slow controlled manner. If the wheels of the machine become stuck during operation, disengage the clutch and STOP THE ENGINE before attempting to free the machine.

The trenching arbor is located between the two rear wheels. Align the center of the machine along the route.

  1. Increase engine speed to full throttle.
  2. Slowly engage the clutch control handle.
  3. Turn the trenching arbor depth control handle to lower the trenching arbor into the ground.
  4. Slowly pull the TRENCH'N edge a short distance.
  5. Disengage clutch and stop the engine.
  6. Check the depth of the trench.
  7. Restart the engine and reset depth control crank as required.
  8. Engage clutch and continue to trench.


Do Not Operate On Steep Slopes. Maximum Angle of Slope is 15 Degrees.

Always trench across the face of slopes, never up and down. Always be careful of footing, especially on slopes. Do not trench on excessive slopes, maximum slope is 15 degrees.

Stop the engine whenever you leave the trencher, even for just a moment.

It is possible to trench a double wide trench by making two passes. Align the rear wheel with the edge of the trench form the first pass. Only two passes can be made, do not attempt to make three or more passes without moving one of the rear wheels outside the frame or using the optional Extender Brackett. Do not attempt to trench at an angle to the ground by raising one side of the machine during operation.


To Avoid Serious Injury,
Do not operate the TRENCH'N edge with damaged or loosed components

During operation, if excess vibration occurs, STOP THE ENGINE and inspect the machine. Look for loose hardware or loose or damaged components. Excess vibration occurs after encountering a buried object while trenching, STOP THE ENGINE and inspect the trenching arbor and the arbor teeth.
