Vermeer's autonomous Bale Hawk collected 257 round bales in a single 24-hour field test, the manufacturer has reported. The figure, released alongside a video of the trial, marks the clearest signal yet that the tracked machine is moving beyond short demonstrations towards extended autonomous operation in commercial forage production.

Five years have passed since Future Farming first reported on the concept in 2021. At that stage, Bale Hawk was a proof-of-concept machine. The latest result shows what sustained autonomous running can deliver in practice.

What does the 24-hour figure actually mean?

The 257 bales work out at an average of roughly 10.7 bales per hour across the full test period. Vermeer had set a target of 300 bales in 24 hours, but the machine ran out of work: there were simply no more bales left on the field.

That headline number matters less for its raw speed than for what it says about how autonomy changes the economics of bale collection. A modest hourly capacity becomes far more productive when the machine can keep working around the clock.

Instead of tying up a tractor and driver for hours on bale haulage, the operator can hand the job to Bale Hawk and get on with other work. Bales keep moving long after a manned operation would have stopped for the day.

Vermeer cautions that real-world capacity will vary. Bale density, field size, travel distance to the unloading point, field layout and obstacles will all influence how many bales the machine shifts per hour on any given farm.

How does the machine handle bales?

Bale Hawk locates individual round bales using onboard sensors and navigates through the field without an operator onboard. Rather than piercing each bale with a conventional spear — the standard method on tractor-mounted handlers — loading tracks pick the bale up and move it onto the machine.

Once it has collected three bales, Bale Hawk travels autonomously to a predefined unloading area. The operator sets the location, direction and length of the row where the bales are placed.

The spear-free handling method has a second benefit. Because the machine never inserts a spike into the bale, Vermeer says it helps maintain bale shape and density. For growers selling hay or silage by quality and weight, that could matter as much as the labour saving.

How far along is the development?

Vermeer has now tested Bale Hawk for several years in Iowa and surrounding US states, across different crops and bale sizes. The 24-hour trial is the latest step in that programme and the strongest evidence so far of the machine's endurance.

Remote supervision is also part of the development work. Vermeer's stated end goal is for an operator to monitor the machine while carrying out other jobs elsewhere on the farm — supervising rather than driving.

That frames the value proposition clearly. The benefit is not necessarily faster bale collection. It is the removal of an operator from a repetitive, low-skill operation, and the ability to keep collecting bales for far longer periods than a manned crew would tolerate.

When can farmers buy one?

Not yet. Despite the progress, Vermeer has announced no commercial launch date. The manufacturer still describes Bale Hawk as a concept and confirms it is not currently available for sale.

The 24-hour test nonetheless gives contractors and livestock producers a much clearer picture of how the machine would slot into a real forage operation: slow, steady, unsupervised bale shuttling while labour goes elsewhere.

For now, farmers should watch for the next round of field results and any signal from Vermeer on commercial timing — in particular whether the company moves from concept language to a launch timeline, and what a production-spec Bale Hawk would cost against a tractor-and-spear setup.
