Why buy the Allett UC 10 Blade Cutting Cartridge?

  • Engineered for a super-fine, professional cut on ornamental lawns.
  • Features a 10-bladed SURE-BLADE cylinder made from hardened, ground steel.
  • Achieves an impressive clip rate of 131 cuts per metre for a denser finish.
  • Capable of cutting as low as 3mm, perfect for heights below 20mm.
  • Designed for use with the Allett Stirling cylinder mowers.
  • Thickened bottom blade ensures easier setting for a clean, quiet cut.

Achieve a Flawless, Professional Finish

The Allett UC 10 Blade Cutting Cartridge is the ultimate accessory for lawn enthusiasts seeking a truly immaculate, bowling green-style finish. As part of Allett’s innovative Ultra-Change system, this cartridge is designed to deliver a superior cut on fine turf. It is specifically compatible with the Allett Stirling 43 and 51 mower.

Advanced Cutting Technology

Crafted from hardened and ground steel, the 10-bladed SURE-BLADE cylinder offers a significantly higher clip rate of 131 cuts per metre (cpm) compared to the standard 6-blade cartridge’s 79 cpm. This increased cutting frequency results in a much finer, denser, and more uniform finish, capable of achieving a cutting height as low as 3mm. This cartridge features a new, thickened bottom blade, which not only makes setting the blade easier but also contributes to a cleaner and quieter cutting action.

Ideal for Specialist Applications

This 10-blade cartridge is the preferred choice for maintaining prestigious lawns such as cricket wickets, bowling greens, golf tees, and ornamental home lawns where a pristine appearance is paramount. To see the benefits of the ten-blade system, it should be used for cutting grass below 20mm. For taller grass, there is no advantage over the standard six-blade cylinder. Achieving the best results requires a dedicated maintenance schedule, with mowing recommended 2-3 times per week.
