Case TR320 Attachment Guide — What Fits, What Flows, What Works
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.
Quick Fit Answer
Start with capacity, hydraulic flow, and coupler fit before comparing attachment brands.
Use this for attachment weight plus payload.
Primary number for augers, grapples, brooms, and most buckets.
Confirm the option is installed before buying high-flow attachments.
Mechanical fit still needs hydraulic and weight checks.
Case TR320 Machine Specs
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.

SSQA Coupler Notes
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:
- Any third-party attachment labelled "universal SSQA" mounts directly — no adapter, no modification
- Broadest third-party attachment compatibility of any major brand — effectively every skid steer attachment made in Canada and the US will physically mount to a TR320
- No proprietary plate required — unlike Cat's Work Tool system or older Bobcat configurations, you're not locked into branded attachments
- Older Case numeric-series machines (420, 430, etc.) used a different geometry — this guide applies to the current alpha TR series only

High-Flow Required — 38.3 GPM (One of the Highest in Class)
| 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. |

Canadian Buyer Context
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.
Why the TR320's High-Flow Matters in Canada
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:
- Mulcher heads designed for 36–38 GPM run at their rated RPM and cutting power — not throttled
- Cold planers run at full drum speed — cutting speed and finish quality improve directly with GPM
- Commercial snow blowers with high-demand fans get full discharge velocity
SSQA Advantage for Canadian Buyers
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.
What to Avoid on the TR320
- Assuming HF is always installed: The TR320's high-flow is a factory option on some configurations. On a used machine, verify by serial number before buying any high-flow attachment. Don't assume based on model name alone.
- Attachments requiring 40+ GPM: The TR320's ~38.3 GPM HF covers the vast majority of skid steer–class attachments. A small number of dedicated forestry heads and large-format planers specify 40+ GPM minimum. Check the specific attachment's flow requirement — not just "high flow required."
- Over-weighting the front: At ~3,200 lb ROC, the TR320 handles nearly any attachment comfortably. But very heavy bucket configurations loaded with dense material (wet concrete, scrap steel) combined with a heavy attachment frame can approach the ROC limit. Always calculate total load.
Case TR320 Buyer FAQ
What high-flow attachments can a Case TR320 run?
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.
What bucket size is best for a Case TR320?
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.
What quick-attach system does the Case TR320 use?
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.
Is the Case TR320 a good choice for contractors in the Prairie provinces and Ontario?
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.
