View Full Version : Do any 21" commercial mowers cut higher than 4"
10-12-2004, 08:55 PM
I am in need of getting a 21 inch for some of my smaller account and some trim work in ditches.
The problem is I cut St. Augustine at 4.5" and I can only find mowers that will adjust up to 4".
Any suggestions or ideas.

Have you tried looking for larger wheels that fit whatever mower you are using?

Isn't 4.5" a little high for St Augustine?? We cut all our St Augustine at 3.5" I've never seen a 21 cut that high.

TRY THE BILLY GOAT CONTOUR MOWER. IT HAS A 6.5 HORSE MOTOR AND A 24" CUTTING DECK.. www.billygoat.com :drinkup:

As far as cutting too high. Univ of Florida recommends 3.5-4.5 in cut on St. Augustine. The higher cut allows for better photosynthesis while shading out competitors and keeping the soil cooler and wetter.
Result, less weed invasion and less need for irrigation. My results at 4.5 have been great.I have one client that demands a 3.5in cut and their yard has not lushed up nearly as well as the others cut at 4.5 in.
Most of my clients have floratam, with dwarf palmetto it is less important because the crown is lower on the palmetto. Floratam has a very high crown and cutting at 3.5 will only leave 1/2-3/4 in above the crown.
Looking into larger wheels, but that is a nuisance. Why will my toro 36WB go to 4.5 and my gravely PM260 got to5 in but no pusher will go past 4 in? seems crazy.

I've been curious about this too. the popular toro 21" prolines have 6 positions starting at .75" and moving up to 3.25" in .5" increments. How do you match up your trim mower with the other equipment if you mow higher than 3.25"? I'd sure like to see the 4.5" St. Augustine, it sounds nice. :blob3:

So far my search shows nothing available over 4". My not so knowledgeable dealer thinks it is something to do with OSHA. He thinks they cap the height at 3.5" but obviously with mowers in his showroom at 4" that isn't right.

Just got off the phone with my other (slightly smarter) dealer and he say he has some toro Pro 21" that go to 4.5". Sounds like I will be making a trip up there tomorrow to see if it is true.

Never heard of a Proline that goes to 4.5"...even if you get it above 4" the cut will suck....No 21" i've used gives a decent cut above 3.5"....

Hopefully that has to do with type of grass as far as the cut goes. I can't imagine cutting st augustine at 3". Dead lawn in a few months.
I am going to the dealer to look today.
