Ask a golfer what makes a great green and they will talk about speed and smoothness. Ask a superintendent and, sooner or later, the conversation turns to the quality of the cut. Every blade of grass on a green is cut several times a week. Whether that cut is clean or ragged decides a great deal about how the turf copes with heat, wear and disease.
Clean cut versus torn leaf
A sharp reel and bedknife act like a pair of scissors: the leaf is sliced cleanly and seals quickly. A dull reel behaves more like a blunt knife: it crushes and tears the leaf, leaving a frayed, browning tip.
Torn leaves lose more water, take longer to recover and give fungal pathogens an easy way in. Trials run by the Sports Turf Research Institute (STRI) in the UK compared different sharpening regimes and concluded that cleanness of cut can have a significant impact on turf health, with blunt blades leaving turf less able to cope with drought, wear and disease.
Why this matters even more in India
Indian golf courses ask a lot of their turf. Pre-monsoon heat pushes warm-season grasses to their limit, while the monsoon brings humidity and wet-season disease pressure. A plant that is already stressed has little in reserve to repair a torn leaf. On Indian courses, a clean cut is not a cosmetic detail; it is part of the disease-prevention programme.
There is a practical side, too. Dull reels need more pressure to cut, which means more wear on bearings, bedknives and engines. A sharpening routine protects the machine as much as it protects the grass.
Backlapping versus grinding
Many maintenance teams still rely heavily on backlapping, running the reel backwards against the bedknife with a grinding compound. It has its place, but it is slow and only restores an edge to a point. Precision grinding restores the original geometry of the reel and bedknife.
Bernhard and Company, whose grinders are used at leading golf venues worldwide, champions a "non-contact" approach in which the reel and bedknife are set with a fine clearance rather than heavy contact. Its Express Dual reel grinder can sharpen a reel without taking the cutting unit apart, and the Anglemaster grinds bedknives accurately and quickly.
SGDC India became Bernhard official distributor for India in 2021, bringing these grinders and the training to use them well to Indian courses.
Building a sharpening routine
A good programme does not need to be complicated:
- Check the quality of cut daily on greens, using a simple paper test on each cutting unit.
- Grind reels and bedknives on a fixed schedule, and always before the start of the winter playing season.
- Keep records of every grind and setting so each machine is set up the same way every time.
- Train at least two people in the workshop, so sharpening does not stop when one technician is on leave.
A small investment with a big return
A reel grinder is one of the less glamorous purchases a golf course will make, but few machines have a more direct effect on turf health, playing quality and the life of the mowing fleet.
