BULLDOZER BLADE

Blade

BULLDOZER BLADE
The deep experience and the high manufacturing technology developed by Sigma 4 are combined in this line of front dozer blades for crawler tractors. Inspired by an industrial blade design, rugged construction and full reliability, the dozer blade can perform heavy duty jobs at the farm. Clearing land or snow, piling silage, levelling ground, grading…all operations quickly and easily performed.
The sturdy frame is built around the tractor to assure ideal repartition of loads for a high working capacity and a minimum stress on the tractor. The reversible double edged blade is made of highly resistant steel for long durability at work. The efficiency and the rapidity of the frame coupling/decoupling operations  are assured by the smart Velotak quick-fit system.
The Sigma 4 dozer blades are clearing the way to higher productivity.

VELOTAK

QUICK-FIT SYSTEM: SMART SOLUTIONS FOR ENHANCED FLEXIBILITY
Velotak is a quick-fit system developed by Sigma 4 to speed up all operations of coupling/decoupling of the frame onto the tractor. By moving the tractor, the pins (P), placed on the fixed frame, slide into the proper slots (S) placed on the movable frame. The system is then locked by sliding lever (L) acting on the position of pin (G). The pin (G) will have a locking function when in lowered (position 1) and unlocking when raised (position 2).
The frame will decouple simply by shifting the lever (L) in position 2 and moving the tractor in reverse speed; for the coupling operation, the lever (L) can stay in position 1 as the device will lock-in as the tractor moves forward, without any additional operation.
