• The single-piece plastic tube eliminates air and water seepage for hay quality unsurpassed on the market.
• Stretch film plastic tube tightens around bales, eliminating movement of air inside the tube.
• The machine moves forward each time it indexes a bale.
• Field-tested performance up to 100 bales per hour.
• Tube easily adjustable to diameter and shape of bales.
• Self-sufficient operation - bale ram propelled by 9 HP gas engine.
• Sliding support plate facilitating tube installation.
• Automated tube filling thanks to its hydraulic bale ram.
• Hydraulic steering adjustment.
• Removable hitch.

The SilaTube use stretchable and recyclable plastic tube: 150' (45.7 m) long (35 x 4' bales (1.2 m)) or 220' (67.1 m) long (53 x 4' bales (1.2 m)).  

ROUND BALES

For round bales, we need to know the bales diameter.

SQUARE BALES

For square bales, we need to calculate the half-perimeter.
Stack height + Bale lengths - 8" (for round corners) = half-perimeter

CHOICE OF PLASTIC TUBES

The choice of plastic tubes for use with the Pronovost SilaTube is of great importance. The SilaTube was designed at the base to stretch the plastic with great power to allow it to shrink down tight against the bales. This eliminates oxygen and creates an air tight environment. The choice of plastics must therefore be appropriate in order to meet the criteria of elasticity, memory and resistance to tearing and piercing. Also, as plastics will be exposed to sunlight for a period of up to one year, they must be provided with UV protection.

Certain plastic manufacturers are specialized in products compatibe with the Pronovost SilaTube. The present list has exclusively an informative purpose. Pronovost makes no judgment, positive or negative, with regards to the listed companies. The fact that the name of a company is included shall not be interpreted as constituting a recommendation. It is possible that other manufacturers produce tubes compatible with Pronovost SilaTube Pronovost and the absence of a company should not be interpreted negatively.
