How to Use a Trencher: Beginner's Guide

Dig precise trenches for irrigation, electrical lines, and drainage without breaking the bank — rent a trencher locally through RNTR and get the job done right the first time.

This guide walks homeowners, DIYers, and small contractors through everything they need to know about renting and operating a trencher safely and efficiently — from choosing the right machine to finishing the job and returning the equipment.

Trencher Rental: Frequently Asked Questions

How much does it cost to rent a trencher?
Trencher rental rates through RNTR typically range from $150 to $400 per day depending on the machine type and your location. Walk-behind chain trenchers run on the lower end, while ride-on or wheel trenchers cost more. Weekly rates are usually available and can save you 30 to 50 percent compared to renting by the day if your project spans multiple days.
What size trencher do I need for my project?
For most residential projects — laying irrigation lines, low-voltage cable, or shallow drainage — a walk-behind chain trencher cutting 4 to 6 inches wide and up to 24 inches deep is plenty. For deeper utility trenches or harder soil, a ride-on trencher offers more power and speed. When you search on RNTR, local providers list the cutting depth and chain width for each machine so you can match the specs to your job.
Do I need any experience to rent a trencher?
No prior experience is required, but you should read the operator manual and watch a brief walkthrough before you start. Most local RNTR providers will walk you through the controls at pickup. This guide covers the core steps so you arrive prepared and confident.
Is a deposit required when renting a trencher?
Most RNTR providers require a security deposit at the time of rental, typically ranging from $100 to $500 depending on the machine. Deposits are held and released once the equipment is returned in good condition. RNTR also offers up to $2,000 in damage protection on eligible rentals, giving you added peace of mind.
Can I get a trencher delivered, or do I have to pick it up?
It depends on the local provider. Many RNTR equipment suppliers offer delivery and pickup for larger machines like ride-on trenchers, often for an additional flat fee. Smaller walk-behind trenchers can usually be transported in a pickup truck or trailer. Check the listing details on RNTR to see which options your local provider offers.
How long does a typical trenching project take?
A straightforward residential trench — say, 100 linear feet for an irrigation line — typically takes 2 to 4 hours of machine time in average soil. Factor in setup, marking, and cleanup and you can usually complete a standard project in a single day rental. If your soil is dense clay or rocky, budget extra time and consider a more powerful machine.
What should I do before I start digging?
Call 811 (the national call-before-you-dig number) at least two business days before your project so underground utility lines can be located and marked. Failure to do this can result in serious injury and expensive repairs. Once utilities are marked, walk your trench line, remove surface obstacles, and review the operator controls before you power up the machine.

What You Need to Rent and Use a Trencher

Walk-Behind Chain Trencher

A walk-behind chain trencher uses a rotating chain with carbide teeth to slice cleanly through soil, cutting trenches typically 4 to 6 inches wide and up to 36 inches deep. It's the go-to rental for homeowners installing irrigation systems, landscape lighting wire, or French drains. When renting, look for adjustable depth settings and a model suited to your soil type — sandy loam is forgiving, but clay or rocky ground calls for a heavy-duty chain.

Ride-On Trencher

Ride-on trenchers are self-propelled machines capable of cutting deeper and longer trenches faster than a walk-behind unit, making them the right call for contractors or ambitious DIYers tackling water main lines, electrical conduit runs, or drainage projects over 150 linear feet. They're heavier and wider, so confirm you have adequate access to your work area and that you can transport the machine — many RNTR providers offer delivery for these larger units. Check the chain pitch and horsepower rating on the listing before booking.

Wheel Trencher (Rock Wheel)

A wheel trencher replaces the chain with a circular cutting wheel studded with carbide teeth, designed specifically for hard ground, compacted gravel, or pavement. If your project involves cutting through asphalt, concrete, or extremely rocky soil, a wheel trencher will outperform a chain unit dramatically. These are specialty rentals — search RNTR by equipment type or ask your local provider whether a wheel attachment is available for the machine you're booking.

Safety and Protective Gear

Personal protective equipment is non-negotiable when operating a trencher. You'll need steel-toed boots, safety glasses or goggles, work gloves, and hearing protection — trenchers are loud. High-visibility clothing is a good idea if you're working near a road or other workers. Most of this gear you likely already own; if not, pick it up before your rental window starts so you're not losing paid time.

How to Use a Trencher: Step-by-Step

Follow these steps to complete your trenching project safely and efficiently with a rented machine from RNTR. Whether you're installing irrigation lines, running conduit, or adding drainage, the process is straightforward when you prepare properly.
  1. Step 1: Plan Your Trench and Call 811

    Mark your trench route with spray paint or marking flags before your rental window even begins. Measure the total linear footage so you can estimate your time accurately. Most importantly, call 811 at least two business days before digging so utility companies can locate and mark underground lines. This is legally required in most states and protects you from hitting gas, electric, or water lines. Once utilities are marked, plan your route around them.
  2. Step 2: Book the Right Trencher on RNTR

    Search RNTR for trencher rentals near you and filter by cutting depth. For irrigation or landscape wire, a walk-behind chain trencher (24-inch depth capacity) is usually sufficient. For deeper utility work, step up to a ride-on model. Confirm whether the provider offers delivery or if you'll need a trailer — check RNTR's trailer size guide if you're unsure what size hauler you need. Book your rental, pay securely through RNTR's Stripe-powered checkout, and note the pickup time.
  3. Step 3: Set Up and Inspect the Machine

    When you pick up or receive delivery of the trencher, do a walk-around inspection with the provider. Check the chain tension and condition, confirm the engine oil and fuel levels, test the depth adjustment mechanism, and make sure the chain guard is secure. Ask the provider to walk you through the throttle, depth control lever, and forward/reverse controls if you haven't operated this model before. Take photos of the machine's condition before you leave — this protects your deposit.
  4. Step 4: Dig the Trench

    Position the machine at your starting point with the chain raised. Engage the chain, then slowly lower it to your target depth while moving forward at a steady walking pace — rushing causes the chain to bind and the machine to bounce. Keep the trench line straight by picking a fixed reference point ahead of you. Pile the excavated soil consistently on one side of the trench so it's easy to backfill later. For turns, raise the chain, reposition, and resume cutting. If you're also doing concrete or masonry work nearby, RNTR has guides on complementary equipment like how to use a cement mixer for sealing trench entry points.
  5. Step 5: Install Your Lines and Backfill

    Once the trench is complete, lay your pipe, conduit, or cable as required by your project specs. Use sand bedding under and around PVC pipe for irrigation lines to prevent cracking. For electrical conduit, follow local code for burial depth — typically 6 inches for low-voltage and 24 inches for standard electrical. Backfill in layers, tamping each layer down with a hand tamper or plate compactor rental to prevent settling. Mark where buried lines run so future digging doesn't accidentally cut them.
  6. Step 6: Clean Up and Return the Equipment

    Remove loose soil from the chain, housing, and drive components using a stiff brush or low-pressure water rinse. Check that the chain tension is where you found it and that no guards or covers are missing. Return the machine during your agreed window — late returns can result in an additional day charge. RNTR's rental terms are clear on this so review them before your project starts. Once the provider inspects the machine, your deposit is released promptly.
