Toro Procore 660

"That's what I like to see," says one of our testers, inspecting the holes left by the Procore. "That's going to let the air, water and fertiliser in. And once you have run over it with a mower, it's playable." He is clearly impressed and it's easy to see why.

The 660 is effective, productive and versatile. We reckon it is ideal for relieving compaction, controlling thatch and enabling gaseous exchange in the soil. What’s more, this aerator works off a compact tractor — 24hp will do.
With a working width of just over 1.5m, the 660 covers the ground well. Forward speed controls the spacing, so at one kilometre per hour, spacing is 38mm and at four kilometres per hour the spacing is 127mm. Being offset to one side of the tractor, there is no need to worry about tyre marks.
It is belt-driven, and not all grounds staff are fans of belt drive, but there are three drive belts to each flywheel. This ensures maximum power delivery and means that if one belt breaks, there are still two left to complete the job.
The workings of the 660 are simple. RotaLink geometry is the clever centering mechanism that controls the tine arm action. It ensures the tines remain perfectly vertical as they enter and leave the ground, producing consistently circular holes as the tractor moves forward. Individually floating turf holders keep the turf secure as the tine is withdrawn, preventing turf lift and helping to maintain a true and level surface. A large roller minimises compaction and gives consistent hole-depth.
“It’s smooth and so quiet, even going at a good pace,” says a tester. The 660 can cover 2,137sq m/h at the closest spacing and 7,132sq m/h at 127mm. Another tester is also impressed with the selection of tines available for this aerator.
Adjusting working depth is simply a matter of removing a pin and turning a crank handle. A gauge marks the depth in five-millimetre increments.
Maintenance is a dream, with access via a hinged cover. The RotoLink system has no bearings and those on the main shaft are sealed for life. Only six grease nipples need regular attention.
Procore 660 is suitable for most turf areas — tees, greens, fairways, pitches and parks. Its big brother, the two-metre-wide 880, offers higher performance of 0.8ha an hour for sports fields.
