The purchase price is just the start. Fuel, maintenance, wear parts, operator time, and insurance all add up. Here's an honest breakdown of actual operating costs — in Canadian dollars, for real conditions.
People focus on attachment purchase price and forget everything else. A $6,000 brush cutter sounds like a clear winner over paying a contractor $200/hour — until you account for the fuel to run it, the cutting teeth you'll replace, the machine maintenance that scales with hours of use, and your own time. Sometimes the contractor is still cheaper. Sometimes you come out way ahead. The math depends on how many hours you actually run the attachment.
This guide walks through every cost component so you can build an honest picture before buying.
Attachment costs only make sense in the context of the machine they're running on. If you don't own a skid steer yet, your operating cost structure looks very different from someone who's had a machine for five years with the capital cost amortized.
A new mid-size skid steer or CTL — something like a Bobcat S590 or Kubota SVL65-2 — runs $80,000–$105,000 CAD in 2025. Financed over 5 years at 6% on $80,000, that's roughly $1,530/month. If you run the machine 250 hours a year, that's $73/hour in capital cost before you turn the key.
A used machine at $45,000 with 1,800 hours changes the calculation significantly. Capital cost over 5 years drops to around $9,000/year, or about $36/hour at 250 hours/year.
The point: don't evaluate attachment economics in isolation from your machine cost. Both need to be in the picture.
Skid steers run on diesel. Fuel consumption depends heavily on what attachment you're running and how hard it's working.
| Work Type / Attachment | Estimated Consumption | At $1.80/L Diesel (CAD) |
|---|---|---|
| Light work (bucket loading, moving material) | 5–8 L/hr | $9–$14/hr |
| Medium work (trenching, auger, grading) | 8–12 L/hr | $14–$22/hr |
| Heavy hydraulic work (mulcher, cold planer, high-flow broom) | 12–18 L/hr | $22–$32/hr |
| Maximum hydraulic load (large disc mulcher at full throttle) | 16–22 L/hr | $29–$40/hr |
Diesel prices in Canada vary significantly by province and whether you're in an urban or rural area. Northern and remote communities can see diesel at $2.20–$2.80/L. Urban southern Ontario and Alberta hover around $1.60–$1.90/L depending on the market. Adjust the fuel cost column accordingly for your region.
Farm operators in Alberta, Saskatchewan, and Manitoba can access coloured diesel (purple fuel / marked fuel) at a reduced tax rate — typically $0.40–$0.60/L cheaper than highway diesel. If you're running a skid steer for agricultural work, this is worth checking with your provincial regulator. It's legal for farm use; illegal for highway vehicles.
Manufacturers publish maintenance intervals but not always the cost. Here's a realistic breakdown for a mid-size skid steer (Bobcat S595-equivalent) operated in Canada.
Oil and filter changes: Every 500 hours, or annually, whichever comes first. Fluid and filters for a skid steer oil change run $120–$200 at dealer cost. DIY with bulk oil and aftermarket filters: $60–$100. At 250 hours/year, this is a $60–$200 annual cost.
Hydraulic fluid: Check regularly; change every 1,000 hours or 2 years. Hydraulic fluid change on a skid steer runs $200–$350 in fluid cost plus shop time. Contaminated hydraulic fluid is one of the most common causes of attachment failure — this maintenance item matters.
Air filter: Replace every 500 hours in dusty conditions (mulching, tillage, construction sites). $40–$80/filter. Budget $50–$160/year depending on operating environment.
Fuel filter: Annually. $30–$60.
Drive chain / sprocket (wheeled machines — tires): Tires on a wheeled skid steer typically last 2,000–4,000 hours. Replacement: $800–$1,400/tire (set of 4 runs $3,200–$5,600 CAD at dealer pricing). That's $0.80–$2.80/hour depending on tire life. Foam-fill tires cost more upfront but eliminate flats on rocky sites.
Tracks (CTL): 1,500–2,500 hours on mixed surfaces. Replacement: $7,000–$12,000/pair (both tracks). That's $2.80–$8.00/hour in track cost alone. Abrasive surfaces destroy tracks fast.
Unplanned repairs: Budget $1,500–$3,000/year for a machine running 250–400 hours annually. Hydraulic cylinder seals, coupler wear plates, electrical gremlins, hose replacements — it adds up. Older machines with high hours should budget $3,000–$5,000/year.
Total annual machine maintenance budget: $3,500–$8,000/year for a well-maintained mid-size skid steer running 250–400 hours.
This is the cost most buyers underestimate. Attachments wear — and some wear fast.
Every attachment with a cutting edge — buckets, box blades, dozer blades, land planes — has a replaceable cutting edge. Standard bucket cutting edges in 84-inch configuration (hardox or similar) run $180–$350 for the edge plus bolts. Replacement frequency depends heavily on what you're digging: prairie topsoil might give you 300–500 hours per edge; rocky Canadian Shield material might give you 80–120 hours.
Annual cutting edge cost budget: $300–$1,200/year depending on material.
Mulcher teeth are the most expensive wear item in the attachment ecosystem. A full set of replacement teeth for a mid-size drum mulcher (30–40 teeth) runs $800–$2,000 depending on tooth style and brand. Lifespan: 80–200 hours per set in mixed brush; less in rocky areas. Budget $8–$20/hour in tooth cost for a mulcher operating in normal Canadian conditions.
Mulcher owners typically buy teeth in bulk and keep a full replacement set on hand. Running a mulcher to bare spindles costs more than the teeth themselves.
A replacement chain for a 48-inch trencher runs $400–$900 depending on chain pitch and tooth style. Rock carbide chains cost more but last longer in Canadian glacial soils. Chain life: 100–400 hours depending on soil. Budget $2–$8/hour in chain cost for regular operation.
Replacement teeth for a standard 12-inch auger bit: $60–$150 for a full set. Pilot bits: $30–$80. Replacement frequency: rock auger bits in the Canadian Shield or hardpan may need teeth every 20–50 holes. In prairie loam, 200+ holes before replacement is reasonable.
Brush cutter blades (flail-style or fixed-blade) wear at moderate rates. A full blade replacement set for a 72-inch brush cutter runs $200–$500 and typically lasts 150–300 hours. Budget $0.75–$3.00/hour.
This is the cost that private landowners consistently leave out of the analysis. Your time has value — even if you're not paying yourself a wage, you're spending hours on a machine that you could spend doing something else.
If you're a contractor, operator time is your wage cost. A skilled equipment operator in Canada earns $28–$50/hour depending on province, certification, and project type. Alberta and BC construction wages are at the high end; Atlantic Canada is at the lower end. Add 20–30% for payroll taxes, WCB/WSIB, and benefits if you're paying an employee.
If you're a property owner operating your own machine, the implicit cost is your time at whatever hourly value you assign it. Even at $30/hour implied value, 40 hours of operating time represents $1,200 of your time.
Skilled vs unskilled operators matter for attachment efficiency. An experienced operator on a mulcher moves faster, stresses the attachment less, and makes fewer errors that require re-work. A new operator on a trencher in rocky soil destroys more chain. Operator competence is a real cost variable.
Equipment insurance is often forgotten in operating cost calculations but it's real money, especially for commercial operators.
Residential/farm use: A skid steer added to a farm or hobby farm insurance policy typically runs $600–$1,200/year depending on value and use. Some home insurers cover equipment under an umbrella policy; many require a separate inland marine or equipment floater.
Commercial use: A commercial equipment policy for a skid steer used for hire runs $1,500–$4,000/year depending on province, machine value, and what you're doing. BC and Ontario tend to be higher than the prairies. Mulching and tree work push rates up.
Liability: If you're working on other people's property for compensation, general commercial liability insurance is mandatory in most provinces. Minimum $2M coverage runs $1,800–$4,500/year for a small operator.
Getting the machine to the job costs money.
A tandem-axle equipment trailer rated for 14,000–16,000 lbs runs $8,000–$16,000 CAD new. Amortized over 15 years: $530–$1,070/year. Add trailer maintenance and tires at $300–$600/year.
Fuel for hauling: towing a 10,000 lb load with a 3/4-ton pickup increases fuel consumption from roughly 12–13 L/100km to 18–22 L/100km. A 100-km round trip to a job site adds $20–$35 in extra towing fuel at current diesel prices.
If you're paying a driver to haul the machine: add their time at the same operator rate plus the truck/trailer overhead. Commercial equipment transport services in Canada charge $200–$500 for local moves depending on distance and region.
Let's build a real per-hour cost for a typical Canadian owner-operator running a mid-size CTL with a brush cutter attachment, 300 hours/year:
Machine capital cost: Used CTL at $60,000, 5-year horizon = $12,000/yr ÷ 300 hrs = $40/hr
Fuel: 10 L/hr average × $1.80/L = $18/hr
Machine maintenance: $4,500/year ÷ 300 hrs = $15/hr
Track wear: $9,000 replacement ÷ 2,000 hr life = $4.50/hr
Brush cutter blades: $350/set ÷ 200 hr life = $1.75/hr
Insurance (equipment + liability): $3,500/yr ÷ 300 hrs = $11.67/hr
Operator value (your time): $35/hr implied = $35/hr
Trailer amortization: $800/yr ÷ 300 hrs = $2.67/hr
Total estimated cost per operating hour: ~$128/hr
That $128/hour isn't what you'd charge a customer — it's what it costs you to operate. A contractor charging $150–$200/hour for brush clearing is covering their costs and making a margin. At $128/hour true cost, a self-operator doing their own brush clearing saves money relative to hiring at $180–$200/hour — but it's not the dramatic saving that the simple "attachment costs $6,000, contractor charges $200/hour" math suggests.
For owners who already have a machine, the decision is simpler: how many hours until the attachment pays for itself?
| Attachment | New Cost (CAD) | Contractor Rate Alternative | Est. Break-Even Hours |
|---|---|---|---|
| GP Bucket (72") | $1,800–$3,500 | N/A — you need a bucket to run the machine | N/A — mandatory |
| Brush Cutter (72") | $4,500–$8,000 | $150–$220/hr (clearing contractor) | 30–55 hours |
| Trencher (48") | $5,000–$12,000 | $130–$200/hr (trenching contractor) | 40–90 hours |
| Auger (drive unit + 12" bit) | $2,500–$5,000 | $90–$160/hr (post hole contractor) | 25–55 hours |
| Drum Mulcher (60") | $18,000–$35,000 | $180–$320/hr (mulching contractor) | 90–195 hours |
| Snow Pusher (10 ft) | $3,000–$5,500 | $80–$150/push (snow contractor) | 25–70 pushes |
| Stump Grinder | $9,000–$18,000 | $100–$200/stump | 90–180 stumps |
These break-even estimates assume the attachment is working against the contractor alternative rate and don't include your operator time. If your time has high value (you're a professional who bills at $80–$150/hour doing something else), the break-even extends. If your time is genuinely spare or lower-value, the break-even shortens.
