“Compatible with dozens of attachments” — what the KS1000’s hydraulic flow actually limits

By Justin, Product Engineer · Based on official factory specifications and industry hydraulic flow documentation, September 2026

TL;DR: The KS1000's auxiliary hydraulic circuit delivers 89 L/min (about 23.5 GPM) at 200 bar (about 2,900 PSI). That places it in the standard-flow category, which comfortably runs buckets, forks, grapples, and most auger and trencher attachments, but is not rated for high-flow attachments like forestry mulchers or cold planers.

The real spec this article confirms

Our KS1000 compact crawler loader lists a BONDIOLI hydraulic pump and a double gear pump, and is listed as compatible with dozens of attachments. Its official hydraulic system specification confirms the auxiliary circuit delivers 89 L/min at 200 bar, roughly 23.5 GPM at 2,900 PSI in the units used across the North American attachment market. With this figure confirmed, we can give a direct answer to which attachments it actually powers at full rated performance, not just which ones mechanically bolt on.

Where 89 L/min (23.5 GPM) sits in the industry's flow categories

Industry documentation on compact loader and skid steer hydraulics consistently splits auxiliary flow into two broad bands: standard flow, typically 17 to 25 GPM (roughly 64 to 95 L/min) at around 3,000 to 3,500 PSI, and high flow, typically 30 to 45+ GPM (roughly 114 to 170+ L/min) at similar or higher pressure. At 23.5 GPM, the KS1000 sits toward the upper end of the standard-flow band, with pressure slightly below the upper end of that band's typical range.

What this confirms you can run at full rated performance

In practical terms: the KS1000's 89 L/min circuit comfortably covers the attachments most compact loader buyers actually run, buckets, pallet forks, grapples, standard augers, and standard trenchers, at their intended speed and torque. It is not the right machine to pair with a high-flow-rated forestry mulcher, cold planer, or similarly motor-heavy specialty attachment; those are built for machines rated well above 25 GPM.

Why the pressure number matters alongside flow

Flow (L/min or GPM) determines how fast a hydraulic motor can turn. Pressure (bar or PSI) determines how much force or torque is available. At 200 bar, the KS1000's pressure is within the standard-flow category, though toward its lower-middle range compared with machines running closer to 3,000 to 3,500 PSI. For most standard-flow attachments, this is not a practical limitation, but if you are comparing an attachment's full specification against the KS1000, check both numbers, not flow alone.

How to check any new attachment against this figure

1. Find the attachment's rated flow requirement in L/min or GPM, usually printed on the attachment or its documentation.

2. Compare it directly against the KS1000's confirmed 89 L/min (23.5 GPM).

3. If the attachment's rating is at or below roughly 90 L/min (24 GPM), expect full rated performance.

4. If the attachment is rated above that, particularly anything advertised as "high-flow only," expect reduced speed and power, or check with the attachment manufacturer whether it has a minimum flow requirement the KS1000 would not meet.

Frequently asked questions

What is the KS1000's hydraulic flow rate?
89 L/min at 200 bar, which converts to approximately 23.5 GPM at 2,900 PSI.

Is the KS1000 a standard-flow or high-flow machine?
Standard flow. Its 23.5 GPM output sits within the industry's standard-flow range of 17 to 25 GPM, below the 30+ GPM threshold typically used to define high flow.

Can the KS1000 run a forestry mulcher or cold planer?
Not at full rated performance. These attachments are typically rated for high-flow systems of 25 to 45+ GPM, above the KS1000's standard-flow output.

Can the KS1000 run a standard auger or trencher?
Yes. Standard auger drives and utility trenchers are typically rated within the 10 to 25 GPM range, which the KS1000's 23.5 GPM output comfortably covers.

What happens if I attach something rated above 25 GPM?
It will generally run slower and underpowered than its rated speed, since the KS1000 cannot supply the flow the attachment is designed around.

Does pressure (200 bar) limit anything specifically?
It sits within the standard-flow pressure range but toward the lower-middle of it. For most standard-flow attachments this is not a practical limitation; check an attachment's specific pressure requirement if comparing closely matched options.

Feature availability varies by configuration; confirm current specifications directly with Rhinoceros before ordering a specific attachment. Attachment flow requirement ranges cited are general industry categories and individual attachment specifications should be checked against the confirmed 89 L/min, 200 bar KS1000 figure.
