Single and dual axle chaser bins
Curved upper sides of a Davimac chaser bin

Curved Sides

The distinctive curved bin sides allow the bin to withstand the stress of a full load without buckling under the strain.

The rubber cushion hitch in between the chassis and A-frame

Unique cushion hitch

The cushion hitch between the chassis and A-frame is unique to Davimac. It protects the tractor and bin from shunting during transport, delivering a smoother ride whatever the conditions.

Steep sides

Keep even the trickiest grains flowing with high-angle 55° bin sides. You'll get more grain in the silo and less stuck inside the chaser bin.

Low loading height

A low loading height of 3.3m on both sides means you can easily upload from a header on either side of the bin with a lower risk of collision.

Detail of an auger

Tough auger

Unload bushel after bushel with zero stress. The huge 20" diameter vertical auger is constructed from 10mm flights fully welded to the internal spine to reduce bowing under strain.

Unload faster

Our augers are designed to maximise harvest efficiency. The huge 20" augers unload up to 12 tonnes per minute, so you can have a full 35-tonne load in the truck in under 3 minutes.

Auger guard

The auger protection guard shields the vertical auger from damage from bumps and collisions. Get peace of mind knowing even the greenest chaser bin driver can only bust the guard and not the auger itself. 

An auger spout with LED lights on either side

Spout lights

Keep working through twilight and into the night with super bright 3,000 lumens LEDs mounted to the auger spout.

Tough construction

Davimac chaser bins are made to last. 10 and 16mm plate in the chassis make sure it can take the weight of the biggest harvest, with 6.4 and 3mm sheet steel in the sides to keep the aggregate weight down.

CTF Centres

CTF Centres

Standard axles are adjustable from 2.6 to 3m CTF-standard widths to reduce soil compaction from repeated machinery passes.

The tyres on a dual axle chaser bin

High floatation tyres

Keep moving with tyres designed to minimise compaction and maximise floatation. Choose the tyre to suit your needs, all with dual bead construction and heavy ply ratings to keep working longer and more reliably.
