Ferris IS 2600 61

The IS 2600 combines a diesel engine with chassis suspension in a smaller package than Ferris's IS 6200. It is a useful candidate for buyers whose route favors a roughly 60-inch cut and who want to compare diesel ownership without moving straight to a much larger machine.

Read the exact model column

This review covers 5901929, with a 61-inch deck, 904cc three-cylinder Yanmar and ZT-4400 transaxles. Ferris's specific SKU table lists 23 hp, while the general page header says 24 hp. Our specification field follows the SKU table; confirm the engine rating on the supplied unit before ordering. The difference is disclosed rather than silently combined into a new number.

Maximum forward speed is 10 mph. Neither the rating nor maximum speed tells you the finish at your preferred mowing pace. Request a demonstration with grass conditions that resemble the actual job.

Suspension does not make every seat the same

The documented system has independent front control arms and a rear swing-arm, using adjustable coil-over shocks. The seat is listed as premium mid-back with adjustable armrests. Do not assume it includes the IS 6200's seat package because both machines carry the Ferris name.

Use the suspension guide to plan a comparison. Check adjustment range, access to the controls and how the mower feels at a sensible cutting pace. The quality of that fit matters more than the number of comfort features in a brochure.

Price a working configuration

Ferris lists US MSRP $24,419 and Canadian MSRP C$32,966, checked October 7, 2026. These are suggested prices with additional charges excluded, not dealer offers. The machine warranty is described as two years with unlimited hours or four years/500 hours; obtain complete terms and separate engine coverage.

Ask for service pricing as well as the selling price. The removable floor pan and engine-compartment latches are relevant to a maintenance demonstration: have the dealer show the routine access points and explain which tasks you will do.

Who should consider it

Compare this model with the Kubota ZD1021-60 if you want two different approaches to a smaller commercial diesel. Keep a suitable gas mower on the shortlist too. The diesel ownership checklist helps establish whether annual use and support justify the premium, without assuming a universal fuel-saving percentage.

Our ZT Score

7.9/10 — our research-based editorial assessment using the ZeroTurn scoring method.

• Cut quality (30%): 8.0/10. The iCD deck and greaseable spindles support a substantial cutting package; no measured finish advantage has been established.
• Build & durability (25%): 8.2/10. ZT-4400 drive and commercial spindle construction support repeated-use suitability, not an assumed diesel lifespan.
• Comfort (20%): 8.0/10. Front and rear suspension offers adjustment beyond a seat alone; the listed mid-back seat limits comparison with the more elaborate IS6200 package.
• Value (15%): 6.9/10. Published MSRP requires meaningful use and a favorable comparison with gas alternatives, rather than automatic credit for diesel fuel.
• Ease of use (10%): 7.7/10. Service access and foot lift are useful; configuration verification and complete machine access measurements remain necessary.

Provisional research-based editorial judgement for commercial mowing, not a hands-on test. No reliable model-specific owner consensus or measured fuel-use comparison was established. Cut and comfort scores assess documented equipment and require a local demonstration. Value uses the manufacturer MSRP, not a delivered dealer quote.
