Our dual-axle chaser bins deliver the capacity and all-day reliability that large broadacre operations demand. Available in 30T, 35T, and 45T sizes, they're built in Central West NSW with a tandem walking-beam undercarriage rated well above maximum load capacity and engineered to keep working as hard as you do.
Our dual-axle models are the harvest workhorse for large operations and designed to keep pace with the biggest headers through the longest days. The latest models raise the bar on every front with bigger capacities, more standard features, and performance that's engineered for the demands of a modern Australian harvest.
Besides the larger capacity, our 45T model has all the Davimac features you know and love from our chaser bin range plus:
✔ 24" vertical unload auger - 18T/min
✔ 20" horizontal auger
✔ Steering axle with hyd lock
✔ Hydraulic brakes (optional)

THAT MAKE DAVIMAC THE BEST.
The wheel centres on 30T and 35T models are user-adjustable from 2.56 m to 3.0 m for Controlled Traffic Farming (CTF) operations. 45T models are fixed at 3.0 m centres.
The floating walking beam suspension allows the bin to travel smoothly over uneven ground while keeping load distribution even along the chassis. On the 45T model, a rear-steering axle enhances manoeuvrability and minimises soil impact, and can be hydraulically locked for added stability when reversing.
Engineered for maximum strength and reliability, the axle is rated to carry up to 80 tonnes [1]. The 12-stud hub exceeds the industry-standard 10-stud, reducing the risk of wheel failure under heavy loads for superior performance in tough conditions. Our bins are fitted with durable, Australian-engineered Harvest tyres.
Davimac bins are built long and low for maximum stability and easy filling. Wheel arches give them one of the lowest bin heights on the market, improving loading efficiency and reducing the risk of header auger collisions during harvest. The low centre of gravity ensures a steadier ride in the field and makes road transport safer and more straightforward.
Our rubber-cushioned A-frame absorbs shock when travelling over uneven terrain, reducing stress on the chassis and extending the service life of both the grain cart and your tractor. Paired with the interchangeable ball hitch, Davimac bins deliver one of the smoothest and most stable towing experiences in the paddock.
Harvest in style! The distinctive curved sides of a Davimac chaser bin aren’t just for looks—they’re engineered to handle the stress of a full, heavy load without the buckling risk of straight walls. Steep 55° angled sides promote smooth, consistent grain flow down to the horizontal auger for faster, more efficient unloading.
QUICK UNLOAD:
Our single-fold discharge auger maximises harvest efficiency with an unload speed of up to 12 tonnes per minute for 20" models and 18-tonne per minute for 24" models [2].
Left-hand side or right-hand side discharge is available according to your preference.
CONTROL THE FLOW:
✔ The hydraulic spout with rubber chute allows you to focus the angle and adjust the flow of grain with complete accuracy and control.
✔ A hydraulic kicker allows easy adjustment of the discharge angle and height of the vertical auger for tricky mother bins, semis or silos.
✔ A shut-off door at the base of the vertical auger allows flow-rate control for fast metering crops and easier cleaning.
✔ Auger function can be easily confirmed and monitored via the perspex window at the base of the vertical auger.
ULTRA-BRIGHT AUGER LIGHTS:
Twin 48W 16 LED 3,000 lumens lamps mounted to the auger spout enable safe and efficient night operation.
STRONG CONSTRUCTION:
The rugged dual-auger design features a vertical auger with fully-balanced 10 mm-thick flights on a 150 mm centre pipe, and a chain-driven horizontal cross auger—16" on 30T/35T models or 20" on 45T models—with 6 mm flights. An auger guard protects against damage and collisions.
✔ FULLY-REPLACEABLE PARTS
Our tandem axle bins have been designed with easy to replace bolt-on parts for simple and straight-forward maintenance.
Spare parts are available to order online.
✔ INCLUDED WITH BIN
✔ NO ESCORT REQUIRED – 30T & 35T
A contractor's dream. The 30T and 35T models have a low transport profile. With wheel centres retracted and the auger folded into transport position, these models generally do not require a road escort [3], helping reduce relocation costs.
