Quick answer: Rent a mini excavator when the job is mainly digging down: trenches, footings, stump holes, drainage tile, or utility lines. Rent a skid steer (or a compact track loader, its tracked cousin) when the job is mainly moving material across the surface: grading, spreading gravel or topsoil, clearing brush, and loading trucks. Many site jobs need both. Before you rent either, confirm your truck and trailer can legally and safely haul the machine, and contact MISS DIG 811 at least 3 business days before you dig. Michigan law requires a dig notice at least 72 hours before excavating with power equipment.
What each machine does well
Mini excavator
A mini (or compact) excavator has a boom, stick, and bucket on a house that rotates on tracks. It digs below the surface where it sits and places spoil to the side, which makes it the right tool for:
- Trenches for water, drainage tile, electrical conduit, or footings
- Digging around existing utilities once they are located and exposed
- Removing stumps and large rocks
- Digging holes for posts, ponds, or septic components
- Working in tight spaces, especially with a reduced or zero tail swing model whose rear stays close to the tracks as it turns
It is slow at moving material any distance. Each scoop has to be swung, dumped, and the machine walked forward.
Skid steer and compact track loader
A skid steer is a loader with lift arms and a quick-attach plate on the front. It drives to the material, scoops, and carries it. It is the better choice for:
- Grading and leveling a pad or driveway
- Spreading gravel, topsoil, or mulch
- Back-filling trenches
- Moving pallets with forks
- Clearing brush and small trees with a grapple or mulching head
- Loading a dump trailer or truck
It can dig shallow cuts with a bucket, and it can run an auger, but it is not built to dig deep or narrow trenches.
Wheels or tracks
Loaders come with tires (a skid-steer loader) or rubber tracks (a compact track loader). Bobcat's buyer's guide sums up the tradeoffs:
| Condition | Wheeled skid steer | Compact track loader |
|---|---|---|
| Soft, muddy, or uneven ground | Wheels can slip or dig in | Lower ground pressure, continuous traction |
| Pavement, concrete, gravel | Tires grip well and wear slowly | Tracks wear quickly on pavement |
| Lawns and turf | More rutting | Less damage, minimal rutting |
| Speed and turning | Typically faster, turns more sharply | Usually lower top speed |
| Running cost | Generally cheaper to own | Tracks, rollers, and idlers need inspection and replacement |
For a soft, wet site or a finished lawn you have to cross, tracks are the better fit. For a gravel yard or paved site, wheels make more sense.
Sizes and what the numbers mean
Mini excavator classes
Rental yards group mini excavators by operating weight. United Rentals, for example, lists classes from 2,300 to 2,500 pounds (5 to 6 feet of dig depth) up to 14,800 to 18,600 pounds (13 to 15 feet of dig depth). A few of its published classes:
| Operating weight class | Max dig depth |
|---|---|
| 2,300 to 2,500 lb | 5 to 6 ft |
| 4,200 to 4,900 lb | 8 ft |
| 7,400 to 8,500 lb | 10 to 11 ft |
| 10,500 to 12,000 lb | 11 to 12 ft |
| 14,800 to 18,600 lb | 13 to 15 ft |
United Rentals notes that the smallest models start at about 3 feet wide, which matters for gates and backyards, while larger models are about 7 feet wide. Pick the smallest class that reaches the depth you need and fits through your access.
Loader rated operating capacity
For skid steers, the key number is rated operating capacity (ROC), the load the machine is rated to lift and carry. Manufacturers tie it to tipping load. Kubota, for example, lists its SSV65 skid steer's rated operating capacity as 50 percent of tipping load, at 1,951 to 2,690 pounds depending on configuration. If you plan to move pallets of block or full buckets of wet soil, ask the rental yard for the ROC of the exact machine and compare it to your heaviest load.
Attachments
Attachments often decide the rental. Common ones include:
- Skid steer: dirt and general-purpose buckets, pallet forks, augers, grapples, box blades and grading attachments, trenchers, brush cutters and mulchers.
- Mini excavator: narrow and wide digging buckets, grading or ditch buckets, hydraulic thumbs for grabbing stumps and rock, augers, and hydraulic breakers.
Hydraulic attachments have to match the machine's hydraulic system, and some heavy-duty attachments need a high-flow machine. Ask the yard to confirm the pairing. Some yards rent machines with the attachment already fitted.
Getting it to the site
Hauling is where many first-time renters get into trouble. Before you agree to tow:
- Get the machine's operating weight, plus attachments and fuel, from the rental yard.
- Get the trailer's empty weight and its gross vehicle weight rating (GVWR). The machine plus the trailer must stay under the trailer's GVWR.
- Check your truck's towing capacity, hitch rating, and gross combined weight rating in the owner's manual or on the door placard. Do not rely on the hitch ball rating alone.
- Confirm the trailer has working brakes and your truck has a brake controller. Michigan's Vehicle Code (MCL 257.705) only exempts trailers with a gross weight under 3,000 pounds from the all-wheel brake requirement for new trailers, and only when other conditions are met. Even the smallest mini excavator class United Rentals lists weighs 2,300 to 2,500 pounds before you add the trailer, so a loaded equipment trailer will almost always be over that line.
- Ask whether the combination of your truck and their trailer requires a commercial driver's license, and whether delivery is available instead.
Delivery costs money but removes the towing risk. Ask whether the driver unloads and places the machine.
Operator safety
NIOSH's publication Preventing Injuries and Deaths from Skid-Steer Loaders (No. 2011-128) gives operators clear rules, including:
- Operate with the seat belt fastened and the restraint bar in position.
- Never bypass interlocked controls.
- Enter and exit only with the bucket flat on the ground or the lift-arm support in place.
- Carry loads low and travel and turn with the bucket as low as possible.
- Do not travel across slopes. Go straight up or down with the heavy end uphill.
- Never carry riders.
For trenches, federal OSHA requires a protective system (sloping, shoring, or a trench box) for excavations 5 feet deep or more, unless the excavation is entirely in stable rock (29 CFR 1926.652). Shallower trenches still need protection if a competent person sees signs of a potential cave-in. Michigan employers are covered by MIOSHA, so check MIOSHA's excavation rules for your work. Never let anyone stand in a trench next to an operating machine.
Call MISS DIG 811 before you dig
Michigan's MISS DIG Underground Facility Damage Prevention and Safety Act (Public Act 174 of 2013) applies to excavation, which the law defines as moving earth, rock, or other material below the surface "with power tools or power equipment," including grading, trenching, digging, and augering. Under MCL 460.725:
- You must provide a dig notice at least 72 hours, but not more than 14 calendar days, before you start. MISS DIG 811 tells homeowners to contact it at least 3 business days ahead. Call 811 or submit a request online. The service is free.
- A ticket is valid for 21 days from the start date, or 180 days if the work will not be finished within 21 days.
- Each excavator on a shared site files its own notice.
- Within the caution zone, which the law defines as 48 inches on either side of the facility marks, you must expose marked facilities before using power equipment there. The law defines soft excavation, the method meant to avoid damaging lines, to include hand-digging, cautious digging with nonmechanical tools, vacuum excavation, and pneumatic hand tools.
- Do not start before the start time on your ticket, even if all the marks are down.
MISS DIG does not mark private lines that a utility did not install, such as lines to a shed, detached garage, pool, sprinklers, or invisible dog fence. Hire a private locator for those.
Questions to ask a provider
- What is the operating weight and width of the exact machine I will get?
- For a mini excavator, what is its maximum dig depth, and is it a reduced or zero tail swing model?
- For a skid steer, what is its rated operating capacity, and is it wheeled or tracked?
- Which attachments are included, and do they match the machine's hydraulic flow?
- Do you deliver, and what does delivery cost to my address?
- If I tow, what does your trailer weigh, what is its GVWR, and does it have brakes?
- Do you include a walk-through on controls and safety features?
- What does the damage waiver cover, and what am I liable for?
- How are hours metered, and what counts as a day or a week?
