Rotary tillers and soil conditioners for skid steers. What they actually do, what your machine needs to run them, and why you can't use one on frozen Alberta clay.
A skid steer tiller attachment does what a rototiller does, but at machine scale — and on soil that would stop a garden tiller cold. You mount it to the quick-attach plate, connect the hydraulic lines, and the rotor spins to break up, aerate, and level ground for seeding, landscaping, or prepping a base. The end result is a loose, workable seedbed with the larger clods broken down and debris either mixed in or thrown to the sides.
Two categories dominate: the rotary tiller and the soil conditioner. They look similar from a distance. They're not the same machine. The differences matter depending on what you're doing.
A rotary tiller uses L-shaped or C-shaped hardened steel tines mounted on a horizontal rotor. The rotor spins and the tines chop into the soil, turning it over and breaking up clods to a consistent depth. Tilling depth typically runs 4 to 8 inches depending on soil density and machine power. At 6 inches, you're getting into the compaction zone where most subsoil hardpan starts — adequate for new lawn prep, food plots, and nursery beds.
The rotor turns in one direction on basic models. Bi-directional tillers — where the rotor can run either forward or reverse — give you more control over how aggressively the attachment bites. Running the tines in reverse (counter-rotation) produces a finer, more pulverized finish. Forward rotation digs more aggressively and handles harder ground better.
A soil conditioner is faster than a tiller and handles more surface area per pass. It uses a large-diameter drum with bolt-on carbide-tipped teeth instead of L-tines. The drum spins at high RPM, pulverizing soil and throwing rocks and debris to either side into a windrow. That windrow is then easy to pick up with a bucket or rake. Soil conditioners are common for finish grading before sod or seeding — they leave a level, fine surface without the deep cultivation a tiller provides.
Bobcat's own soil conditioner attachment — their branded version runs 60" to 84" widths — is a good example of what a premium soil conditioner does. It grades, pulverizes, and windrows in one pass. Speed is the advantage over a rotary tiller. Tilling depth and rooting capability are where the tiller wins.
This is where a lot of people get stuck. Tiller attachments are hydraulically demanding. They don't run off a cylinder like a bucket does — they use a continuous-rotation hydraulic motor, and that motor needs sustained flow to spin the rotor efficiently.
Standard flow skid steers deliver roughly 12–20 GPM at 2,500–3,500 PSI. The TMG-SRT72, a popular 72" bi-directional rotary tiller sold through TMG Industrial (with distribution in Langley, BC), specifies 18–23 GPM at 2,900 PSI. That's right at the upper end of what standard-flow machines deliver. On a Bobcat S550 or similar mid-frame machine producing 16.9 GPM standard, the tiller will run — but not at full rotor speed. The tines will drag in harder soil instead of spinning cleanly through it.
High-flow machines change the picture entirely. A Bobcat S770 in high-flow mode delivers 37 GPM. Run a 72" tiller off that and the rotor spins fast enough to handle compacted clay soils that would stall a standard-flow setup. If you regularly need to till heavy ground, high-flow capability is worth factoring into your machine selection or rental choice.
| Machine Type | Standard Flow | High Flow | Tiller Compatibility |
|---|---|---|---|
| Bobcat S550 / mid-frame | 16.9 GPM / 3,300 PSI | 26.4 GPM | Standard-flow tiller OK; high-flow preferred for 72" |
| Bobcat S770 / large-frame | 20.7 GPM / 3,300 PSI | 37 GPM | Excellent for any tiller width up to 84" |
| Cat 262D / 272D | 19.5 GPM / 3,335 PSI | 34 GPM | Standard flow covers most 60–72" tillers |
| Kubota SVL75-2 track loader | 19.6 GPM / 3,553 PSI | N/A (no high-flow) | Works well on 60" standard-flow tiller |
Wider is faster — but only on machines that can power the additional rotor length. A 72" tiller on a 16 GPM machine will bog in tough ground. A 60" tiller on the same machine often does fine.
For most Canadian landscape and farm work, 72" is the sweet spot. It covers roughly two tire-width passes in a single pass, moves along quickly in loam or sandy soil, and fits through standard gate openings. An 84" tiller starts to feel oversized on anything under 80 horsepower. It's more at home on a large-frame CTL (compact track loader) than a wheeled skid steer.
On the small end, 48" and 60" tillers are popular for tight urban lots, community gardens, and hobby farm beds. Weight drops considerably — a TMG 60" unit comes in around 520 lbs versus 650 lbs for the 72" — which matters for smaller machines with lower rated operating capacity.
L-tines are the most common. They're reversible — bolt-on, use both cutting edges, then replace. A set of 72" tiller tines typically runs 16–24 tines depending on rotor diameter and spacing. TMG tines are bolt-on replaceable. Budget $150–300 CAD for a full tine set on a mid-size unit.
C-tines (curved) dig more aggressively and handle sod and root mats better. They're common on heavier European brands like FAE and Seppi, which are priced higher but are workhorses in vineyard and orchard applications where you need to till between established plants at depth.
Carbide-tipped tines exist for rocky ground — BC Interior, Canadian Shield terrain, anywhere the soil has embedded stone. Carbide tips last 3–5x longer than standard hardened steel in abrasive conditions but cost more upfront. For BC operators tilling rocky hillside ground, carbide tips are worth the premium.
Let's be blunt: a skid steer tiller is a warm-season tool. Prairie winter. Frozen ground. The tiller bounces off.
In Saskatchewan and Manitoba, frost penetrates 4–6 feet by February. Even in a mild Alberta winter, the top 18–24 inches are locked solid by December. A rotary tiller will not break frozen ground. The tines hit ice-hard soil and the rotor stalls, loads up the hydraulic system, and you risk popping relief valves or bending tines. Don't try it.
The practical tilling window in most prairie provinces runs late April through October — once overnight lows are consistently above freezing and the top 6–8 inches have thawed and dried out enough to till without turning into sticky gumbo. Wait for the soil to reach that point where it breaks cleanly instead of smearing. Tilling wet clay just creates clods that bake into concrete when they dry.
BC coastal operators have a much longer window. The Lower Mainland and Vancouver Island can see tilling work from March through November. Interior BC is closer to prairie conditions — Kamloops and Kelowna see ground frost, though not as deep as the Prairies.
TMG Industrial is a Canadian company (headquartered in Langley, BC) that sells direct and through dealers. Their SRT72 bi-directional rotary tiller is one of the most commonly rented and purchased 72" tillers in western Canada. It specs at 18–23 GPM, handles 2,900 PSI, weighs approximately 660 lbs, and uses a universal skid steer quick-attach plate. The SRT72 typically sells in the $3,200–$4,000 CAD range new, though pricing shifts with the Canadian dollar and steel costs. TMG backs it with Canadian warranty support — worth something when the nearest dealer isn't a six-hour drive away.
Land Pride (a Kubota subsidiary) makes the SRT series of skid rotary tillers — the SRT2572 (72") and SRT2584 (84") are the relevant sizes. Land Pride specs these at 15–21 GPM, which makes them compatible with most standard-flow machines. Build quality is solid. Dealer network in Canada runs through Kubota dealers, so parts and service are accessible in most provinces. New price on the SRT2572 lands around $4,500–$5,500 CAD depending on dealer and configuration. Spec sheet: landpride.com SRT Skid Tiller.
Both US-based brands with Canadian dealer distribution. Virnig's V50 rotary tiller runs 15–22 GPM, weighs 680 lbs at 72", and uses replaceable bolt-on tines. Blue Diamond's heavy-duty tiller is similar spec territory. Both are available through Canadian equipment dealers, typically landing $4,000–$6,000 CAD for a new 72" unit. US exchange rate matters here — prices fluctuate.
Used skid steer tillers show up on Kijiji, Iron Planet, and Ritchie Bros. regularly. Budget $1,200–$2,500 CAD for a used 72" unit in working condition. Inspect tines closely — a full set of worn tines means $200–400 CAD at minimum to get back to usable cutting. Check the motor seal for hydraulic leaks, and look at the gearbox (if present) for any signs of oil loss. Most tillers don't have gearboxes — direct-drive is common on mid-range units — but higher-end models use planetary gearboxes that need oil checks.
New lawn prep is the biggest market. If you're seeding a new property or redoing an established lawn damaged by grubs or drought, a 72" tiller on a mid-frame skid steer will break up the top 6 inches, work in any soil amendments you've top-dressed, and leave a seedbed ready for hydroseeding or sod. One machine, one pass.
Food plots on rural properties — grain fields converted for wildlife management, hobby farms growing market gardens — are a natural fit. Breaking up hayfield sod is hard work. A tiller handles it faster than discing, especially on smaller acreages where a full-size disc is cumbersome.
Revegetation after pipeline and utility work. This is big in Alberta and northeastern BC. After a right-of-way gets cleared and the pipe is in, you need to re-establish vegetation over a long narrow strip. A skid steer tiller can work that ROW faster than any tractor setup on terrain that's too broken-up for a straight tractor run.
Commercial landscaping for new housing subdivisions. Developers bring in skid steers with tillers to prep lots before topsoil spreading and hydroseeding. The combination of tiller plus grade blade in one machine keeps the crew count down.
Know your machine's hydraulic output. Not the horsepower — the actual GPM and PSI at the auxiliary port. Your owner's manual has this. If you don't have the manual, look up your machine model on the manufacturer's site. Match that to the tiller's minimum flow requirement, not the preferred range.
Check that your quick-attach plate is universal skid steer (also called the standard ISO/SAE pattern). Most tillers ship with universal mounts. Some older machines use proprietary plates — you may need an adapter.
Flat-face hydraulic couplers are standard on newer equipment. Older machines use Pioneer-style couplers. TMG and most current tiller brands include flat-face couplers. If your skid steer has older Pioneer-style ports, buy the adapters before the attachment arrives on your job site.
Weight matters on soft or sloped ground. A 660-lb tiller on the front arms changes your machine's balance point. Track loaders handle this better than wheeled skid steers on soft ground. If you're tilling on slopes, a CTL is meaningfully safer.
