The Cat 259D3 is a small CTL that punches well above its weight class. The XPS high-flow system at 36.5 GPM means this machine can run large-class mulchers, snowblowers, and cold planers that bigger-ROC machines with lower flow cannot. Here's exactly what it can run and how to make the most of the XPS system.
The 259D3 is Cat's entry-level compact track loader in the D3 platform. Powered by the Cat C3.3B diesel, it has a relatively modest 1,500 lb ROC — but the optional XPS (eXtended Power System) high-flow at 36.5 GPM is disproportionately powerful for this machine's frame size, enabling attachment classes that many larger-ROC machines can't access.
The 259D3 ships with Cat's proprietary Work Tool Coupler system. This is not universal SSQA geometry — Cat's plate dimensions differ from the industry-standard SSQA mount. Key points:
Cat's XPS (eXtended Power System) is what makes the 259D3 exceptional for its frame size. Here's how the two flow modes compare:
| Mode | Flow (GPM) | Runs |
|---|---|---|
| Standard Flow | 24.5 GPM | Buckets, forks, augers, grapples, breakers, brooms, landplanes, trenchers, concrete mixers, post drivers, snow pushers, power rakes |
| XPS High Flow | 36.5 GPM | Mid-class mulchers, commercial snowblowers, cold planers, soil conditioners, flail mowers, rotary cutters — attachments that other small CTLs cannot run |
Standard flow = 24.5 GPM. XPS high flow = 36.5 GPM (if equipped). ROC = 1,500 lbs — weight management is important on this smaller-framed machine.
| Attachment | Compatibility | Notes |
|---|---|---|
| GP Buckets (dirt, gravel, rock) | ✅ Standard Flow | 60–66" optimal. 1,500 lb ROC is the key limit — watch payload density with heavy material |
| Pallet Forks | ✅ Standard Flow | 1,500 lb ROC; useful for lighter pallets and material staging. Not suited for heavy-duty pallet work |
| Bale Spears | ✅ Standard Flow | Smaller round bales and square bales work. Large 1,500 lb rounds will push or exceed ROC |
| Auger Drives (std flow) | ✅ Standard Flow | Standard-flow auger drives work well at 24.5 GPM; up to 18" bits in most soils |
| Dozer / Angle Blades | ✅ Standard Flow | 72–84" width optimal for this frame; passive attachment suits smaller ROC |
| Grapples (root, rock, brush) | ✅ Standard Flow | 54–66" widths; 1,500 lb ROC means weight of loaded grapple matters — lighter material preferred |
| Snow Pushers (box blades) | ✅ Standard Flow | 8'–10' optimal; passive attachment, no hydraulics required |
| Power Rakes / Landscape Rakes | ✅ Standard Flow | Good match — residential and light commercial landscaping suits the 259D3's size |
| Landplanes / Box Blades | ✅ Standard Flow | 72–84" typical; passive attachment |
| Sweepers (angle brooms) | ✅ Standard Flow | 60–72" optimal; hydraulic brooms at 12–22 GPM well within 24.5 GPM std flow |
| Post Drivers | ✅ Standard Flow | Std-flow post drivers work well |
| Cement / Concrete Mixers | ✅ Standard Flow | Most drum mixers run 10–18 GPM; 24.5 GPM handles comfortably |
| Hydraulic Breakers (mid-size) | ✅ Standard Flow | Mid-size breakers 12–22 GPM run well; large breakers may need XPS flow |
| Attachment | Compatibility | Notes |
|---|---|---|
| Mid-Class Mulchers / Forestry Heads | ✅ High Flow (XPS) | Mulchers rated 28–36 GPM run well on XPS. The 259D3 XPS is strong enough for mid-class forestry work that most small CTLs can't touch |
| Snow Blowers (commercial) | ✅ High Flow (XPS) | Commercial snowblowers 26–36 GPM work with XPS. Confirms why this machine is used in Ontario landscape contracting for winter operations |
| Cold Planers (light to mid) | ✅ High Flow (XPS) | Light cold planers (28–36 GPM) work on XPS — unusual capability for a machine this size. Popular in BC/AB road maintenance crews |
| Rotary Cutters / Brush Cutters | ✅ High Flow (XPS) | High-speed brush cutter motors at 28–36 GPM run well on XPS |
| Flail Mowers | ✅ High Flow (XPS) | Commercial flail mowers 25–35 GPM run well on 36.5 GPM XPS |
| Soil Conditioners | ✅ High Flow (XPS) | Tiller/conditioner heads 25–36 GPM work; 36.5 GPM XPS delivers full rated performance |
| Hydraulic Breakers (large) | ✅ High Flow (XPS) | Large breakers 25+ GPM benefit from XPS; pair with machine ROC awareness |
| Stump Grinders | ⚠️ Marginal | XPS flow is adequate; however, commercial stump grinders can weigh 1,600–2,500 lbs — which may exceed the 259D3's 1,500 lb ROC. Verify attachment weight carefully |
| Attachment | Compatibility | Reason |
|---|---|---|
| Large-Class Forestry Mulchers (40+ GPM) | ❌ Not Recommended | Large forestry mulchers requiring 40+ GPM exceed the 36.5 GPM XPS output. Also: ROC of 1,500 lbs is too low for heavy commercial forestry heads |
| Heavy Rock Buckets (dense fill, full load) | ❌ Not Recommended | Heavy plate rock bucket + dense material easily exceeds 1,500 lb ROC. Use appropriately-sized lighter buckets for rock and aggregate |
| Large Trenchers (heavy-duty) | ❌ Not Recommended | Heavy commercial trenchers can weigh 2,000–2,800 lbs — well past 1,500 lb ROC. Light trenchers only |
| Industrial Cold Planers (large class) | ❌ Not Recommended | Industrial cold planers at 40+ GPM and high operating weight exceed both flow and ROC limits |
The 259D3 is a compact machine. Its 1,500 lb ROC means attachment weight is a bigger consideration than width for most categories. Keep widths proportionate to the machine's frame.
The 259D3 is a capable machine, but the 1,500 lb ROC is a real constraint that operators sometimes underestimate. The XPS high-flow creates a flow capability that can tempt operators into attachment pairings that exceed the ROC:
The Cat 259D3 with XPS is increasingly used in BC and Alberta forestry-adjacent work — land clearing for new construction, right-of-way preparation, and light mulching along utility corridors. The XPS flow lets crews run mid-class forestry heads without stepping up to a much larger, heavier machine that doesn't fit in tight site access. Cat dealer support in BC and AB comes from Finning Canada, with locations across Vancouver Island, the Lower Mainland, BC Interior, and throughout Alberta.
In Ontario, the 259D3 is commonly found in landscape contracting companies that need a compact CTL with real high-flow capability. The machine's smaller footprint fits on residential and commercial job sites where a larger CTL would cause damage or access issues. The XPS system lets Ontario landscape contractors run snowblowers, soil conditioners, and brush cutters without needing a larger machine. Toromont Industries covers Cat dealer service across Ontario, Quebec, and the Atlantic provinces.
Toromont's Cat network extends through Quebec and Atlantic Canada, giving the 259D3 solid dealer and parts support in markets where Cat has strong infrastructure contractor relationships. The XPS-equipped 259D3 finds use in utility and municipal maintenance in these markets where compact machine access is valued.
With XPS, the 259D3 can run mid-class high-flow attachments other small CTLs can't. Just keep the 1,500 lb ROC in mind for every attachment pairing.
