Bulldozer Blades

 
VELOTAK
Consolidated experience, specific know-how and the strictest quality standards: both practical and efficient (starting from the coupling and uncoupling operations, now made even faster and easier thanks to the new “Velotak” coupling/uncoupling system), Sigma4 tiltdozers are clearing the way to increased productivity..
   
 

Backhoes

The Sigma 4 backhoes are three-point-hitched through an adjustable coupling system. They are easily hitched and perfectly locked to the back of the tractor allowing for great stability as well as comfortable and safe operations. Hitching and unhitching procedures are easy and rapid even for non-professional users. While working, the stress is distributed on the two stabilizer legs, safeguarding the tractor. The hydraulic cylinders – fed by a pump which in turn is driven by the tractor P.T.O. – control the movement of arms and bucket. The rams are connected to the hydraulic distributor and operated by means of levers placed on the control console in front of the seat. The Sigma 4 backhoes are for customers looking for an excellent product at the best market price.

The two Sigma 4 backhoe series have the same components and hydraulic parts – the only difference is the shifting frame on the series “C” and the fixed frame in the series “U”.
 
BACKHOES WITH SHIFTING FRAME
series C
The backhoe series “C” is the best selling model. Its frame can be hydraulically shifted with no need of getting off the seat. Side-shift is a very crucial feature for operators working in row cultivations, such as orchards and vineyards, and more in general in narrow areas where stabilizer legs may not be easily fitted.
BACKHOES WITH FIXED FRAME
series U
The backhoe series “U”, without a shifting frame, is particularly suitable for customers who are regularly working on in open fields or gardens. It is extremely stable thanks to the wide open position reached by the stabilizer legs.
