B-ACT (BARONESS Aggression Cutting Technology)

B-ACT gives the world’s greenkeepers unique optional settings to adjust the aggressiveness of their mowers to achieve their ideal conditions.

The cutting performance of the cylinder mower changes greatly depending on the positional relationship between the reel and the bottom blade. The bottom blade attitude and the distance of the bottom blade from the cylinder’s centerline defines the stance; Aggressive or Less Aggressive.

Baroness cylinder mowers are equipped with an adjustment mechanism to achieve variable mowing performances at the same height of cut (HOC) setting. We call this B-ACT.

All around the world golf courses deal with many different conditions and turf. On every golf course, greenskeepers and golfers have individual ideas of the ideal playing surfaces and turf conditions. From this, BARONESS provides options to customize an optimal cutting performance for every customers’ needs and wants with B-ACT.

“I gave it a try and liked it so much that I got the guys who do the cutting to use it, and we were all impressed. In terms of eco-friendliness, the cleaner cut produces virtually no tearing of the leaf, so the sward is less prone to disease and the grass is generally healthier and naturally more vigorous.” (LM56)

Baroness proud to Support the future of Greenkeeping!

“With the need for outstanding performance, ease of maintenance and versatility, for me there was only one greens mower that would be up to the job – the Baroness. I had been through the selection process myself at my previous club, so I knew what I wanted for Ham Manor, but I felt it was important to involve my whole crew in the decision. After a thorough look at the options, everyone agreed that the Baroness was way out in front of the competition.” (LM315)

Paul Brown, Course Manager at Ham Manor Golf Club

“I hadn’t come across Baroness previously and I was a bit wary at first. But having tried others, I decided it gave a better cut, especially on the fairways. And where our previous machine would go off-cut all the time, the Baroness stayed very much on-cut. I even ran the fairway mower across a fairly rough bit of lawn where we have had problems with moles, and its cut wasn’t affected.” (LM2700)

David Knight, Head Greenkeeper at Donnington Grove Golf Course

“The Baroness mowers are easy to operate, easy to maintain and so versatile. We can do everything from a 2” rugby cut to cricket cut using the same machine and it is so easy to adjust. It is all just common sense.” (LM2700)
