The ASV RT-50 is a compact track loader built around ASV's Posi-Track rubber undercarriage system — delivering low ground pressure and turf-safe operation that wheeled skid steers can't match. Here's what it can run, what the hydraulics support, and how to choose attachments that make the most of this machine's soft-ground advantage.
The ASV RT-50 is a compact track loader from ASV Holdings — a Minnesota-based manufacturer known for their Posi-Track rubber undercarriage design. The RT-50 is the mid-range compact model in the ASV lineup: larger and more capable than the RT-30/RT-40, but still focused on the compact footprint and low ground pressure that defines ASV's market position. It's powered by a Perkins 3-cylinder diesel — a reliable, well-supported engine in Canada.
The defining feature of the ASV RT-50 — and the reason buyers choose it over a wheeled skid steer in the same capacity class — is the Posi-Track rubber track undercarriage. This is ASV's proprietary design, and it provides genuine advantages that directly affect which attachments make sense and how the machine performs.
The Posi-Track system distributes the machine's weight across a much larger footprint than rubber-tired skid steers. The result is dramatically lower ground pressure — the RT-50 can operate in conditions that would leave a wheeled machine deeply rutted or stuck. This is not a marginal difference; it's the primary reason operators in certain conditions choose an ASV over a Bobcat or Case wheeled machine.
For landscape contractors, golf course maintenance, sports turf work, and residential lawn applications, the RT-50's rubber tracks are genuinely turf-safe in a way wheeled machines aren't. The low ground pressure means work can continue through the growing season on established turf without the deep tracking and compaction damage that wheeled machines cause. This directly shapes which attachments make sense: landscape rakes, power brooms, turf-safe aerators, and finish grading tools all pair well with a machine that won't destroy what it's working on.
In Canadian spring and fall conditions — softened soil, post-rain sites, riverbank and lakeside access areas — the RT-50's Posi-Track undercarriage provides traction and flotation that wheeled competitors lack. The machine can continue working in conditions where a wheeled skid steer would either tear up the site or get stuck. For operators in coastal BC, Ontario lowlands, or Prairie spring conditions, this is a real productivity advantage.
It's worth distinguishing ASV's Posi-Track system from standard rubber-over-steel-track CTLs from other manufacturers. ASV's design uses an elevated-drive, oscillating undercarriage with high-tension rubber tracks — providing more ground contact conformity and lower ground pressure than conventional CTL undercarriages. This makes the RT-50 more turf-friendly than many competitors even within the CTL category.
The ASV RT-50 uses the industry-standard SSQA (Standard Skid Steer Quick Attach) coupler. Any attachment labelled "universal SSQA" or "standard skid steer fit" mounts to the RT-50 directly, without an adapter plate.
This matrix covers common attachments against the RT-50's ~14 GPM (~53 L/min) standard hydraulic flow and ~1,000 lb (~454 kg) ROC. There is no high-flow option on the RT-50.

| Attachment | Compatibility | Why Not |
|---|---|---|
| Brush Mulchers / Forestry Heads | ❌ NO | Mulchers require 28–40+ GPM high-flow; RT-50 tops out at ~14 GPM with no high-flow option |
| Commercial Snow Blowers (hydraulic) | ❌ NO | Commercial snow blowers require 25–40 GPM; no high-flow available on RT-50 |
| Rotary Cutters / Commercial Brush Cutters | ❌ NO | Commercial rotary cutters require 28–35+ GPM; exceeds RT-50 flow ceiling |
| Flail Mowers (commercial) | ❌ NO | Commercial flail mowers require 25–35 GPM; not compatible with ~14 GPM standard flow |
| Soil Conditioners (full-size) | ❌ NO | Full-size conditioners require 25–38 GPM for acceptable performance; not compatible |
| Cold Planers | ❌ NO | Even compact cold planers require 28–35+ GPM; exceeds RT-50 capability |
| Stump Grinders (mid to large) | ❌ NO | Mid-to-large stump grinders require 25–35 GPM; RT-50 cannot meet this demand |
| Attachment | Compatibility | Weight Guidance |
|---|---|---|
| Bale Spears / Hay Handling | ⚠️ CHECK WEIGHT | Most round bales easily exceed 1,000 lb even when dry. The RT-50's ~1,000 lb ROC makes bale handling marginal — small, dry bales only. Larger bale handling is better suited to machines with higher ROC. |
| Heavy Rock Buckets | ⚠️ CHECK WEIGHT | Heavy AR plate buckets can weigh 500–800 lbs empty. Dense rock payload reaches the ~1,000 lb ROC very quickly. The RT-50 is better suited to light material handling — topsoil, mulch, light gravel, snow. |
| Full-Size Pallet Loads | ⚠️ CHECK WEIGHT | Many standard construction pallets (lumber, masonry, landscaping) weigh 1,000–2,000+ lbs. Verify individual pallet weights before using the RT-50 for fork work. Lighter pallets — bag goods, seedling flats, light materials — are appropriate. |
The RT-50 is a compact machine with a ~1,000 lb ROC. Matching attachment width to frame size is important for both stability and practical usefulness. These recommendations account for the machine's compact footprint and the Posi-Track undercarriage's width.
The RT-50 is an outstanding landscape rake platform. The Posi-Track undercarriage means the machine won't destroy what it's working on — established lawn, finished subgrade, or seeded areas. Power rakes at 54"–66" width for final-grade prep, seed bed preparation, and topsoil spreading are a natural fit. This is one of the best attachments for this machine class.
Road, lot, and surface sweeping is an excellent application for the RT-50. The rubber tracks protect the sweeping surface while the compact footprint allows access to areas a larger machine can't reach. 54"–66" brooms match the machine well. For landscape contractors doing post-construction cleanup, this is a highly practical combination.
A 54"–60" GP bucket for topsoil, mulch, compost, light gravel, and snow is the standard working tool on the RT-50. Keep loads light relative to the ~1,000 lb ROC — this machine is for light material handling, not heavy construction aggregate. The Posi-Track undercarriage excels when working across turf or wet ground with lighter loads.
The RT-50 is a capable snow machine. The Posi-Track undercarriage provides excellent traction in snow and ice conditions, and the low ground pressure means it won't damage asphalt, pavers, or sensitive surface finishes the way heavier machines can. A 7'–9' snow pusher for residential driveways, small commercial lots, and walkway paths is a natural application in Prairie and Ontario winter markets.
Compact root grapples and landscape grapples at 42"–54" are useful on the RT-50 for light brush, shrub removal, and debris handling on turf-sensitive sites. The machine's ground-pressure advantage means grapple work in established landscape areas or post-storm cleanup on lawns won't leave the deep ruts a wheeled machine would.
The RT-50 has no high-flow option and cannot be retrofitted for one. Brush mulchers, commercial snow blowers, rotary cutters, and flail mowers require flow that this machine cannot provide. If your work requires those tools, the RT-50 is the wrong machine — not the wrong configuration. Step up to a higher-capacity ASV model (RT-75 and above with high-flow) for those applications.
The RT-50's ~1,000 lb ROC is notably lower than mid-size wheeled machines. It is a light-duty machine for light materials. Loading a 60" bucket with dense gravel, running large round bale spears, or handling heavy construction pallets will push the machine to or past its limits. Overloading compromises stability, stresses the lift arms, and shortens machine life. Match loads to the machine's actual capacity.
While standard auger drives fit the RT-50, running 14"+ bits in dense clay, compacted gravel, or rock substantially exceeds what 49.5 hp and ~14 GPM can manage. The machine will labor, stall, or damage the auger drive under sustained high-torque demand. Use 6"–10" bits in average-condition soil. For large-diameter hard-ground auger work, use a higher-capacity machine.
The Posi-Track rubber tracks are durable, but they're not indestructible. Prolonged high-speed operation on abrasive concrete or asphalt accelerates track wear. The RT-50 is optimized for soft ground, turf, and mixed-condition sites — not sustained high-mileage on hard paved surfaces. For primarily paved-surface operations, a wheeled machine may be more economical long-term due to lower consumable cost.
ASV Holdings is a Minnesota-based manufacturer with a distribution network covering Canada through dealer agreements with Titan Machinery, Rocky Mountain Equipment, and independent regional dealers. Canadian ASV coverage is reasonable in Prairie provinces and parts of Ontario; more limited in Atlantic Canada and the north.
The RT-50's Perkins 3-cylinder diesel is well-supported in Canada. Perkins has a broad authorized dealer and parts network throughout the country, which means engine parts, filters, and service work are accessible even in areas where ASV-specific dealer coverage is thin. This is a meaningful practical advantage for rural and remote Canadian operators.
Canada's seasonal ground conditions — spring thaw, late-fall wet season, wet-belt regions in BC and Ontario — are exactly the conditions where the RT-50's Posi-Track undercarriage delivers its maximum value. Operators who have tried wheeled machines in spring mud conditions and dealt with the rutting, traction loss, and site damage understand why a low-ground-pressure track machine changes what's possible. The RT-50 isn't a machine for every job — but for the jobs where ground conditions matter, it's in a different category from wheeled alternatives.
The RT-50 is a turf-safe, low-ground-pressure compact CTL with ~14 GPM standard flow. It excels at landscape, finish-grade, and soft-ground work. Choose attachments that play to the machine's strengths — rakes, brooms, light buckets, and snow tools.
