The ASV RT-75 is a mid-frame compact track loader known for one thing above all else: its posi-track rubber undercarriage. Lower ground pressure than steel-tracked CTLs makes the RT-75 the right machine for turf-sensitive work and soft Canadian ground conditions. Here's what it runs, what needs high flow, and which attachments Canadian operators pair with it.
The ASV RT-75 is a mid-frame CTL built on ASV's proprietary Posi-Track platform. Manufactured in Grand Rapids, Minnesota, it is widely sold in Canada through Brandt Industries (Prairie provinces) and Rocky Mountain Equipment (BC and Alberta). These are factory specifications for the RT-75.
ASV built its reputation on one differentiator: the Posi-Track undercarriage system. While Bobcat, Cat, and Deere use conventional rubber track systems, ASV's design is fundamentally different.
The RT-75 uses a multi-roller undercarriage with an independent torsion suspension system — each roller floats independently to follow terrain contours. The track sits on a series of small rollers (rather than a flat idler contact surface), which spreads machine weight across more track contact area. The result is significantly lower ground pressure compared to steel-tracked or conventional rubber-tracked CTLs at similar operating weights.
The RT-75's 20.5 GPM standard hydraulic flow sits in the mid-range for CTLs. It handles the full spectrum of standard-flow attachments competently. The optional 34.6 GPM high-flow system opens access to high-demand attachments. Weight at 9,800 lbs operating weight is manageable for most attachments within the 2,691 lb ROC.
At 20.5 GPM standard, the RT-75 runs all typical skid steer attachments: buckets, forks, grapples, augers, blades, sweepers, post drivers, trenchers, and hydraulic breakers. The 20.5 GPM figure is adequate — not the highest in class, but sufficient for all standard applications without needing the HF kit.
The 34.6 GPM HF output is comparable to Bobcat S650 HF (34.8 GPM) and covers most high-flow attachments: mulchers rated up to ~34 GPM, commercial snow blowers, rotary cutters, flail mowers, and soil conditioners. Very high-demand mulchers requiring 38+ GPM (like those optimal for a Cat 289D3) will be near the edge of what the RT-75 HF can fully support.
The 2,691 lb ROC is similar to the Bobcat S650 (2,690 lbs) and Case SR270 (2,700 lbs). Heavy commercial attachments like large stump grinders and heavy trenchers that approach or exceed this ROC require individual verification.
| Attachment | Compatibility | Size Recommendation | Notes |
|---|---|---|---|
| GP Buckets (dirt, gravel, landscaping) | ✅ YES | 66–72" optimal | Ideal for finish grading on turf-sensitive sites; rubber tracks don't rut soft ground |
| Pallet Forks | ✅ YES | 48" standard | 2,691 lb ROC handles standard construction and farm supply skids |
| Bale Spears | ✅ YES | Single or double spear | Handles large round bales comfortably within ROC |
| Auger Drives | ✅ YES | Up to 18" bits in most soil | Standard-flow auger drives work well at 20.5 GPM; Posi-Track traction helps on slopes |
| Dozer / Angle Blades | ✅ YES | 84–96" | Excellent for finish grading on turf; low ground pressure reduces surface damage |
| Grapples (root, rock, brush) | ✅ YES | 60–72" | Good for woodlot clearing and land development work on soft ground |
| Snow Pushers (box blades) | ✅ YES | 10'–12' optimal | No hydraulics required; works well on turf-over-soft-base surfaces without ripping |
| Power Rakes / Landscape Rakes | ✅ YES | 72–84" | Strong combination — RT-75 is popular with landscaping contractors specifically for power raking finish work |
| Landplanes / Box Blades | ✅ YES | 84–96" | Passive attachment; RT-75 delivers smooth, level passes on soft ground |
| Sweepers (angle brooms) | ✅ YES | 72–84" | Good for parking lot and turf debris cleanup; hydraulic brooms run within 20.5 GPM |
| Hydraulic Breakers (std flow) | ✅ YES | Mid-size class | Mid-size breakers up to 700 ft-lb run within standard flow range |
| Post Drivers | ✅ YES | Standard | Std-flow hydraulic post drivers within 20.5 GPM |
| Trenchers (std flow) | ✅ YES | Mid-range | Verify weight; soft-ground traction advantage of Posi-Track helps in wet trench conditions |
| Cement Mixers | ✅ YES | Standard drum sizes | Most drum mixers run 10–18 GPM; RT-75 std flow handles comfortably |
| Attachment | Compatibility | Notes |
|---|---|---|
| Mulchers / Forestry Heads | HF REQUIRED | RT-75 HF at 34.6 GPM handles mulchers rated up to ~34 GPM; verify individual attachment spec |
| Snow Blowers (hydraulic) | HF REQUIRED | Most commercial snow blowers require 25–40 GPM; HF covers this range |
| Rotary Cutters / Brush Cutters | HF REQUIRED | High-speed heads require 28–35 GPM; HF system needed |
| Flail Mowers | HF REQUIRED | Commercial flail mowers 25–35 GPM; RT-75 HF handles most models |
| Soil Conditioners | HF REQUIRED | Good match with RT-75 — soft-ground traction helps on loose-soil conditioning work |
| Cold Planers | HF REQUIRED | Light cold planers typically need 28–35+ GPM; verify attachment's minimum GPM requirement |
| Attachment | Compatibility | Weight Guidance |
|---|---|---|
| Stump Grinders | CHECK WEIGHT | Commercial stump grinders range 1,800–3,500 lbs. RT-75 ROC is 2,691 lbs — verify individual attachment weight before purchase. Most also require HF. |
| Heavy Trenchers | CHECK WEIGHT | Heavy-duty rock trenchers can reach 2,000–2,800 lbs. Check attachment weight against ROC at operating depth. |
| Large Rock Buckets | CHECK WEIGHT | Thick-plate rock buckets can weigh 1,500–2,200 lbs empty. Add payload and confirm within ROC. |
The RT-75's undercarriage makes it particularly well-suited to specific Canadian applications where ground sensitivity or wet conditions are a factor.
Landscaping and turf contractors working around Metro Vancouver, Victoria, and the Fraser Valley often can't afford ground damage on residential and commercial properties. The RT-75's Posi-Track undercarriage delivers genuine turf protection unavailable on steel-tracked CTLs — a significant competitive advantage on higher-end contracts.
Ontario's golf courses, municipal parks, and commercial landscaping firms use machines that can work on maintained turf without leaving ruts. The RT-75 handles power raking, seeding prep, and material handling on soft-ground Ontario sites where spring thaw creates challenging conditions for conventional tracked machines.
Any Canadian site with soft, wet, or clay-heavy soils benefits from the RT-75's ground pressure advantage. Maritime provinces, the BC Interior, and Ontario's clay belt present conditions where conventional CTLs sink or bog. The Posi-Track system maintains mobility and reduces site damage.
ASV uses an ISO/ANSI standard quick attach plate on the RT-75. This geometry is physically identical to Bobcat's Bob-Tach system, which is the dominant North American standard.
