The John Deere 320G is a popular mid-frame G-Series skid steer with a vertical-lift boom and 2,190 lb ROC. At 21 GPM standard flow with optional 30 GPM high flow, here's exactly what attachments work — and what needs the high-flow option.
The 320G is John Deere's mid-frame G-Series skid steer, positioned between the smaller 312GR and the large-frame 332G. It features a vertical-lift loader design and a Tier 4 Final engine producing 69 gross HP. These are the factory specifications for the standard 320G configuration.
The 320G uses John Deere's QuikTatch system. QuikTatch geometry follows the SSQA (Standard Skid Steer Quick Attach) standard, meaning:
Standard flow = 21 GPM, high flow = 30 GPM (if equipped). ROC = 2,190 lbs.
| Attachment | Compatibility | Notes |
|---|---|---|
| GP Buckets (dirt, gravel, rock) | ✅ YES | 64–72" optimal; 78" max with light material |
| Pallet Forks | ✅ YES | 2,190 lb ROC; 48" standard forks cover most farm and light construction pallets |
| Bale Spears | ✅ YES | Single-tine and double-tine; handles mid-size round bales up to ROC limit |
| Auger Drives | ✅ YES | Up to 18" bits in most soil types; standard auger drives well within 21 GPM |
| Dozer / Angle Blades | ✅ YES | 80–96" width optimal for this frame |
| Grapples (root, rock, brush) | ✅ YES | Runs all grapple types; 60–72" widths suit this ROC |
| Snow Pushers (box blades) | ✅ YES | 10'–12' optimal; passive pushers need no hydraulics |
| Power Rakes / Landscape Rakes | ✅ YES | Hydraulic rakes run well at 21 GPM |
| Landplanes / Box Blades | ✅ YES | 84–96" typical; passive attachment |
| Post Drivers (hydraulic) | ✅ YES | Standard-flow post drivers operate within 21 GPM range |
| Cement / Concrete Mixers | ✅ YES | Drum mixers typically 10–18 GPM; standard flow sufficient |
| Sweepers (angle brooms) | ✅ YES | Hydraulic brooms typically 12–18 GPM |
| Trenchers (standard flow) | ✅ YES | Standard-flow trenchers run well; verify attachment weight vs 2,190 lb ROC |
| Hydraulic Breakers (mid-size) | ✅ YES | Mid-size breakers in 12–20 GPM range; check manufacturer spec sheet |
| Backhoe Attachments | ✅ YES | Mid-size backhoe attachments; verify weight closely vs ROC |
| Attachment | Compatibility | Notes |
|---|---|---|
| Mulchers / Forestry Heads | HF REQUIRED | Light-to-mid mulchers (25–30 GPM) run well with HF installed. The 320G is on the smaller side for sustained mulching — size accordingly |
| Snow Blowers (hydraulic) | HF REQUIRED | Most hydraulic snow blowers need 25–38 GPM; HF required |
| Rotary Cutters / Brush Cutters | HF REQUIRED | High-speed rotary motors need 28–35 GPM at full performance |
| Flail Mowers | HF REQUIRED | Commercial flail mowers typically require 25–35 GPM |
| Soil Conditioners / Tillers | HF REQUIRED | Full-size conditioners need 25–38 GPM; HF kit required |
| Cold Planers | HF REQUIRED | Light cold planers start at 28–35 GPM; HF required |
| Attachment | Compatibility | Weight Guidance |
|---|---|---|
| Stump Grinders | CHECK WEIGHT | Commercial stump grinders range 1,800–3,500 lbs. At 2,190 lb ROC, the 320G is limited to lighter stump grinder units. Verify attachment weight carefully — and confirm HF is installed as most stump grinders also need high flow. |
| Heavy Trenchers | CHECK WEIGHT | Heavy rock-chain trenchers can exceed the 320G's ROC. Stick to lighter-duty trenchers and verify weight rating. |
| Large Rock Buckets | CHECK WEIGHT | Heavy-plate rock buckets plus dense payload can approach or exceed 2,190 lbs. Choose a lighter bucket profile or reduce fill density. |
| Backhoe (heavy models) | CHECK WEIGHT | Some full-size backhoe attachments exceed the 320G's capacity. Verify attachment weight before purchase. |
The 320G runs at approximately 66" overall width. The 2,190 lb ROC and mid-frame build drive these width recommendations.
The 320G is widely used across Canada for farm operations, acreage work, and light construction. Here's what Canadian operators run most often:
The 320G's 2,190 lb ROC suits it well for standard pallet work — building materials, seed bags, and small equipment. Standard 48" forks are the most common choice. For farm use, bolt-on bale spears paired with a pallet fork frame add versatility without buying a second attachment.
Root grapples are a popular add-on for Ontario acreage owners who also do fence-line cleaning and woodlot work. The 320G handles a 60–66" root grapple comfortably within its ROC. Brush grapples suit the Prairie provinces for shelter belt clearing and debris management.
The 320G is a common machine for hobby farm and small commercial snow management. A 10'–12' pusher works well — large enough for farmyard lanes and small parking lots without overloading the machine's capacity.
Fence post augers are one of the most practical 320G attachments for rural Canadian use. Standard auger drives work within the 21 GPM standard flow. In Prairie clay-rich soils, a 9" or 12" bit with a hex drive unit is the typical Canadian setup.
The 332G is John Deere's large-frame skid steer with 3,200 lb ROC and 23.9/33.5 GPM hydraulics. If you're comparing the two for attachment capability:
