SF5 Tractor Range

The ISEKI SF5 Series is a premium out-front mower designed for professional grounds maintenance. Built to deliver exceptional cutting performance, outstanding visibility, and all-day operator comfort, the SF5 is the ideal choice for local authorities, contractors, sports facilities, estates, and commercial landscapes.

Combining powerful diesel engines with a front-mounted cutting deck, the SF5 provides an efficient solution for maintaining large green spaces with precision and ease.

Power and Performance

The ISEKI SF5 Series is powered by a choice of 42hp or 49hp Stage V-compliant ISEKI diesel engines, delivering exceptional torque and reliable performance for tackling long, wet, and dense grass with ease. Designed for maximum efficiency, these fuel-efficient engines help reduce running costs without compromising on power.

A hydrostatic two-pedal transmission provides smooth, intuitive speed control, making the SF5 easy to operate in all mowing conditions. The 48-litre fuel tank allows for extended mowing sessions with fewer refuelling stops, increasing productivity throughout the working day. Operators can also set a consistent forward mowing speed, helping to achieve an even, professional-quality finish while reducing fatigue during long hours of operation.

Operator Comfort

Designed with operator comfort and convenience in mind, the ISEKI SF5 features a clear, easy-to-read dashboard that displays essential machine information, including fuel level, engine temperature, DPF status, operating hours, and warning indicators.

The adjustable display remains clearly visible even in bright sunlight, allowing operators of different heights to work comfortably.

For maximum comfort in all weather conditions, the SF5 is available with an optional enclosed cab complete with heating and air conditioning, creating a comfortable working environment during long days of professional mowing.

Maintenance

The ISEKI SF5 is designed for quick, hassle-free maintenance to maximise uptime. Its cutting deck tilts to 62° without removing the PTO shaft or discharge hose, providing easy access for cleaning, servicing, and blade maintenance. Disc-mounted swing-tip blades help minimise damage if obstacles are struck, while a mulching insert is supplied as standard for added versatility.

Access to the engine bay is straightforward when the high-tip collector is raised and secured, and routine daily maintenance points are conveniently located on the sides of the machine, allowing essential checks to be carried out without lifting the collector.

Collection System & Decks

The ISEKI SF5 offers a choice of 60-inch or 71-inch heavy-duty rotary decks, with cutting height easily adjusted in 10 mm increments using a single-point adjuster. Both decks are shaft-driven for reliable, low-maintenance performance and can be specified with an optional electric stepless height adjustment.

For greater versatility, the SF5 is also available with the Müthing Vario out-front flail deck, allowing operators to switch quickly between cut-and-collect and cut-and-drop modes. The flail deck can also be fitted with scarifying blades, enabling debris to be collected in a single pass for a clean, professional finish.

Collection System

The ISEKI SF5 features a high-capacity 1,300-litre turbine-driven grass collector, designed to maximise productivity and minimise downtime. An oscillating discharge chute ensures clippings are distributed evenly throughout the collector for optimum filling efficiency.

The collector can be emptied at any height up to 2.2 metres, including low-level discharge, providing greater flexibility when unloading into trailers, skips, or disposal areas.

When the collector reaches capacity, a dashboard warning light and audible alert notify the operator, allowing the current mowing pass to be completed before emptying for a more efficient workflow.
