The Case TR320 punches above its weight class on hydraulics. With approximately 38.3 GPM high-flow output — one of the highest figures in the mid-large CTL segment — it runs the most demanding skid steer attachments at full rated capacity. Add in universal SSQA compatibility and 90 hp, and you have a versatile machine with a genuine hydraulic advantage. Here's what that means in practice.
Based on published Case manufacturer specifications, universal SSQA coupler standards, and Canadian dealer context (Case Construction Equipment dealers and RME across Canada). Written for Canadian operators evaluating attachments for the Case TR320. Not a dealer — no inventory verification. Last reviewed: 2026-03-17 by Skid Steer Attachments Canada.
The TR320 is a large-frame compact track loader from Case's TR series. Its standout specification is high-flow hydraulics: approximately 38.3 GPM, which is among the highest in the compact track loader class. This makes the TR320 a serious contender for high-demand hydraulic attachments that other machines in the same size class can't run at full capacity.
Case uses standard SSQA (Standard Skid Steer Quick Attach) across the entire current TR lineup, including the TR320. This is one of Case's strongest selling points from an attachment compatibility perspective:
Standard flow = approx. 22.2 GPM. High flow = approx. 38.3 GPM (optional — verify the specific machine has HF installed before purchasing high-flow attachments).

| Dozer / Angle Blades | ✅ YES | 96"–10' blades well matched to TR320 frame width |
| Grapples (root, rock, brush) | ✅ YES | 60–84" heavy grapples; TR320 ROC supports serious grapple loads |
| Snow Pushers (box blades) | ✅ YES | 12'–16' pushers; high ROC and HP make TR320 a strong snow machine |
| Power Rakes / Landscape Rakes | ✅ YES | 84–96" rakes suited to this frame |
| Landplanes / Box Blades | ✅ YES | 96"–10'; passive attachment, no flow required |
| Post Drivers (std flow) | ✅ YES | Standard post drivers well within TR320 flow range |
| Cement / Concrete Mixers | ✅ YES | Drum mixers run 10–18 GPM; TR320 std flow handles comfortably |
| Sweepers (angle brooms) | ✅ YES | Standard hydraulic brooms run 12–18 GPM |
| Hydraulic Breakers (std flow) | ✅ YES | Mid-size breakers 12–22 GPM; comfortable within std flow |
| Backhoe Attachments | ✅ YES | Mid-to-large backhoe attachments; verify weight vs ROC |
| Attachment | Compatibility | Notes |
|---|---|---|
| Large Forestry Mulchers | ✅ YES (HF) | TR320's 38.3 GPM HF runs even the most demanding skid steer–class mulchers — including heads rated up to 38 GPM that other CTLs in this class can't fully feed. True competitive advantage here. |
| Commercial Snow Blowers | ✅ YES (HF) | Snow blowers rated 25–38 GPM run at full capacity on TR320 HF; very wide selection of compatible models |
| Cold Planers | ✅ YES (HF) | Even high-demand cold planers requiring 35–38 GPM run at rated performance — TR320 HF handles the full range of skid steer–class cold planers |
| Rotary Cutters / Brush Cutters | ✅ YES (HF) | High-speed motors run 28–38 GPM; TR320 HF handles all standard skid steer rotary cutters |
| Flail Mowers (commercial) | ✅ YES (HF) | Commercial flail mowers to 35+ GPM run at full rated output |
| Soil Conditioners / Tillers | ✅ YES (HF) | Tiller/conditioner heads run 25–38 GPM; TR320 HF covers the full range |
| Industrial Sweepers (high-flow) | ✅ YES (HF) | High-speed industrial sweepers run optimally at full HF output |
| Hydraulic Breakers (large) | ✅ YES (HF) | Large demolition breakers requiring 25+ GPM; TR320 power and HF suit heavy breaker work |
| Stump Grinders | ✅ YES (HF) | Commercial stump grinders run 28–35+ GPM; TR320 HF runs them fully. Verify weight vs ~3,200 lb ROC. |
The TR320 is a large-frame CTL. These width recommendations are based on the TR320's footprint, ~3,200 lb ROC, and typical Canadian jobsite usage.
Case sells through the CNH Industrial dealer network in Canada. In the Prairies, the primary Case dealerships include Brandt and Norsemen Equipment — both with broad coverage across Saskatchewan, Alberta, and Manitoba. Ontario and BC are served through CNH-authorized dealers.
Canadian operators increasingly run forestry mulchers, cold planers, and commercial-grade snow equipment that demand 35+ GPM to operate properly. The TR320 at approximately 38.3 GPM HF has more hydraulic overhead than competing CTLs at this size class, many of which cap at 34–36 GPM. In practice, this means:
In Canada's fragmented attachment market — where HLA Attachments (Ontario), McMillan Machinery (BC), and numerous US brands all sell through different distribution channels — the SSQA standard means you're never locked into one manufacturer's ecosystem. Every case-compatible SSQA attachment from every Canadian and US brand mounts directly.
With the optional high-flow system installed, the TR320 delivers approximately 38.3 GPM — one of the highest outputs in the compact track loader segment. This runs commercial forestry mulchers rated up to 38 GPM, cold planers, commercial snow blowers, rotary cutters, flail mowers, soil conditioners, stump grinders, and large hydraulic breakers at full rated capacity. The TR320's high-flow output covers the entire skid steer–class attachment range.
A 72–84 inch bucket is optimal for the TR320's approximately 3,200 lb ROC and large-frame CTL proportions. For high-volume earthmoving in loose soil, an 84 inch bucket maximizes efficiency. In dense rock or demolition material, a 72 inch bucket keeps the loaded weight safely within ROC. The TR320's rubber tracks provide traction advantage over wheeled machines in soft Canadian construction site conditions.
The TR320 uses the industry-standard SSQA (Standard Skid Steer Quick Attach) coupler. Any attachment labelled "universal SSQA" mounts directly without an adapter — including all Canadian brands like HLA Attachments (Listowel, ON), McMillan Machinery, Paladin, and the full used attachment market. This universal compatibility is one of Case's strongest selling points versus proprietary coupler systems.
Yes — the TR320's combination of high ROC, approximately 38.3 GPM high-flow, and rubber track design makes it well-suited for Prairie construction and Ontario contractor use. Brandt Equipment and Norsemen Equipment provide Case dealer coverage across Saskatchewan, Alberta, and Manitoba. In Ontario, the TR320's SSQA compatibility with HLA Attachments' Ontario-made snow pushers, blades, and grapples is a practical advantage for contractors building a multi-attachment fleet.
The TR320's approx. 38.3 GPM high-flow opens every skid steer attachment category. Start with the high-demand tools that justify this machine's hydraulic output — mulchers, cold planers, commercial snow blowers, industrial sweepers.
