Sitrex 3100S

If you've ever watched a heavy rain roll in the same week you finished baling, you know why getting bales wrapped fast matters. The Sitrex 3100S is a trailed bale wrapper built to seal up round bales right behind the baler, locking in forage quality before Pacific Northwest weather has a chance to work against you.

The 3100S takes round bales from three feet ten inches up to five feet three inches in diameter, with a maximum load capacity of 1,984 lbs (900 kg). The side loading fork picks the bale up off the ground without a separate loader, and half-automatic centering settles it onto the cradle with minimal fuss. Direct discharge close to the ground — no platform required — means bales land gently instead of dropping and shifting the wrap.

This wrapper operates through your tractor's hydraulic remotes, and Sitrex lists a power requirement of just 30 HP. That's good news if you're running a compact tractor rather than a full-size ag tractor — you don't need to step up in horsepower just to wrap bales. The adjustable loading fork and adjustable drawbar let you dial in the hookup for your specific tractor and bale size.

The frame's dual-position mobile wheel switches between an inner position for transport and an outer position for working — wider stance for stability while wrapping, narrower for moving between fields or down the road. At eight feet wide and just over fourteen feet long, it's sized to fit through most gates without a fight. Two reel supports and aluminum stretch film rollers (accepting 30 in or 20 in film) keep wrapping consistent bale after bale.

• Small to mid-size hay and forage operations producing round bales
