We will continually add to this list of Popular Reel Mower Questions:
What is the difference between old and new cutting technologies?
All reel mowers have curved type cylinder blades that create a cutting action against a fixed plate. The blades make a spiral around the reel axis, and as they spin, the spiral of blades forces grass past the stationary plate.
Contact (friction) Mowers
This is the “older” more conventional form of cutting method. The cylinder blades are in direct contact with the bed knife and scrape across each other very similar to scissors shearing together. There is generally more friction (hence the name) which causes these mowers to be slightly more difficult to push. The friction also causes noise which can vary depending on each model – some are more quiet than others. Friction mowers generally need to be sharpened every 2 to 3 seasons. If you have a yard full of weeds then a friction mower is the best choice.
Contact-Free (frictionless) Mowers
The newer more modern reel mowers use a contact-free or frictionless cutting system. The term contact-free is used to describe a small gap (usually around 0.05mm) between the reel mower blades and the bed knife. The gap is roughly the width of a human hair and small enough to cut grass, yet big enough to eliminate all friction and noise caused by friction. Contact-free reel mowers are easier to push then the older style making them more fun to use and less tiring. Contact-free mowers cut best when used on healthy turf with minimal weeds. These mowers also cut best when used at lower cutting heights. There are some models available today that claim to be used on 2-3″ cutting range, however, much of the grass is left behind. The best cutting height range is 1-1.75″. Contact-free reel mowers usually do not need to be sharpened for at least 5-10 years depending on use.
When Do The Reel Blades Need Sharpening?
Most mowers stay sharp between 2-4 years depending on use. This can vary from lawn to lawn and manufacturer to manufacturer. You can tell when your reel mower needs to be sharpened when much of the grass passes by the reel and is left uncut.
Contact-free mowers do not require sharpening. Instead, it is a best management practice to adjust the gap distance between the reel and the bed knife. This is very easy can be accomplished in less then 3mins and performed as frequently as needed.
Contact mowers require sharpening on the average of every 2 years. You can purchase do-it-yourself sharpening kit and sharpen your own reel mower.
What Is The Best Cutting Height?
This is a very popular question and a topic with a lot of misinformation – especially if you surf around the internet… Reel mowers cut best when the cutting height is set lower then 2″. When set higher then 2inches, some of the grass tends to get “missed” and multiple passes can be required. For more information please visit our section dedicated to Height Of Cut (HOC).
Should I Buy/Use A Grass Collector Bag?
Our general recommendation is no, however, below are list of the pros and cons. For more information please read about Grasscycling here.
PROs To A Grass Bag
-Grass clippings are good for the compost pile
-Can prevent weeds from spreading if cutting the seed stalks
-Slightly “cleaner” look is achieved when removing more then 1/3 the grass height.
-Wet grass clippings can smother together and will not filter down as easily.
CONs To A Grass Bag
-Grass clippings hold valuable nutrients which can be returned to the soil.
-Grass clippings less then 1inch will filter down to the soil.
-Grass clippings DO NOT cause thatch!
-Unlike rotary mowers, grass clippings are not blown into a pile, they are gently scattered (mulched) behind the mower

I have Emerald Zoysia at my new house and I own have a 4 year John Deere 21″ push mower that does okay but I want to buy a new mower. What type of mower should I buy?
If quality of cut is your top priority, then a good reel mower is the only way to go – a rotary, homeowner grade push mower should be your last choice. Zoysiagrass mowed by a rotary lawn mower looks terrible and you tend to get round scalp marks every time you turn the mower…
We recommend a power reel mower or the Scotts Classic Mower.




























Nice tips. Thanks for the info. Great post!

Great tips. I think the reel mowers are the neatest thing since sliced bread.
