Winter Mower Servicing

Another popular subject this month has been Winter Mower Servicing and in particular what you should expect of your local service workshop.

There have been many tales of work not being done properly and overcharging for service. Here is the minimum that you should expect to be included in a quote for winter service:

Full engine service including checking electrics, starting mechanism, new spark plug, all filters and oil change.
Replace bottom blade (new blade ground-in first)
Re-grind (not back lap) cylinder
Check roller bearings and advise if worn (adjust if possible)
Re-set cylinder to bottom blade clearance and check for even cut
Re-set mowing height to that specified by club.
Treat and touch up paint on any areas of rust
Check and adjust clutch settings
Check belts and replace if worn
Check Groomer and re-set to height specified by club
Check and adjust chain tensions
Lubricate all points
Free off and lubricate all adjustment mechanisms and check for proper operation
Check all cables for wear and replace/re-adjust as required

This is a minimum list and your particular brand of mower might have further items that will need to be checked. Check the manufacturer’s handbook for details, or better still request a winter service checklist from your local dealer.

Now is the time to check that this has all been done properly, not when you are half way across the green with a broken down mower on opening day morning!

Turfgrass Physiology, an introduction

Each of the grass plants in our green is akin to a little factory where Carbon Dioxide and Water are broken down and converted to a sugar based plant food that can be used immediately to fuel the plant's growth processes or converted to starch and stored throughout the plant for future use.

Cool Season and Warm Season Grasses

The main difference between the two groups is the way in which they photosynthesise or produce food for themselves. The first product of photosynthesis in cool season grasses is a 3 Carbon sugar molecule so these grasses are commonly referred to as C3 grasses. In warm season grasses the first

Downcast is back and improved

If a product’s real purpose is to kill earthworms then this is now illegal for turf application in the UK. It's always best to stay compliant with UK pesticide legislation, honest with your players and committee, and aligned with a longer-term view of soil health. That’s been the Bowls Central way since day one.
Downcast is a non-pesticidal liquid that deters surface worm activity and encourages it deeper in the profile. It doesn’t kill worms; it helps keep their good work (aeration, aggregation, nutrient cycling) where it benefits the soil without spoiling the playing surface.

Grass, greenkeepers and the soil food web

The soil food web has become an increasingly popular term in greenkeeping and bowling green management. The problem-solution-problem, or symptoms approach to greenkeeping has been exposed as fundamentally flawed by the diminishing list of available pesticides now available to turf managers. Is there a better way to manage greens...yes. And the extraordinary discovery is that a greenkeeping program that focusses on the green as an eco-system is fully compatible with producing tight, natural turf dominated by the fine perennial Fescue and Bent grasses.
