View Full Version : Cutting full throttle

It may sound like a stupid question, but do you cut grass at wide open throttle?

I read a thread by Terry (exmark) regarding the fuel consumption. ....in it he said that it depends if the person cuts at WOT.

I always cut at WOT because i thought that the grass is cut the sharpest and cleanest at the highest RPM. otherwise, it would just tear it off.

how about the trimmer? do you press to the max if you dont have to?

any opinions?

I cut at wide open and only fill up every 20 lawns same with the trimmer

Not cutting at full throttle puts unnecessary strain on the engine. As far as trimmers, I only cut at full if I have to. Not sure if it makes a difference.

Wide open baby!!! RPM should be 3600 at full throttle and should dip less than 100 under load of baldes. Terry would probably agree with this.

The mowers are made to cut at full throttle. Yes I cut at full throttle. I vary trimmer speed by how much I am cutting off.

I always run at full throttle. And on the 2 cycle trimmers, etc, they are designed to run at full throttle. If you don't , the oil in the oil/gas mixture does not get fully consumed and the excess oild will eventually gum up the carberator.

The govoner maintains a desired rpm. The factory recomended rpm speed for a working motor running at extended periods of time is 3,600 rpm for best performance and efficient operation. Most govoners are set to this speed and different motors use different set speeds, but yes, u should run any mower at its set rpm speed which is full throttle.

yeah me too....i cut at WOT with the mower. i'd hate to double cut or cut until i find the right RPM for that particular lawn. it probably is unnesesary (sp) and it strains the engine

as far as the trimmer....if i am in heavy grass (tall and thick) i cut at WOT. otherwise, i just pull the trigger enough to get it cut.

wonder if it makes any difference.

oh, forgot to add...on my exmark, i dont have an RPM gauge. wish i did!

I run mowers at full throttle, but not trimmers. They just hit me with too much crapola for that. If I can get the job done at half or 3/4 throttle, I do it. The manufacturer probably recommends full throttle at all times, but those engineers aint getting hit by gravel, wires, marbles, small pieces of hard plastic and other assorted garbage during the operation of these things, so I overruled them.

Always WOT on the mower, but only as much as I need on the trimmer..

You're not exactly certain how it'll go for the Gators, either, are you? Make it $20 and you're on.

I run all of my equipment (mowers, blowers, trimmers, etc.) at full throttle. I've heard that it is better for the engines (2 cycle and 4 cycle) to run at full throttle.

I don't think Spurrier will have the Gamecocks (whan an unfortunate nickname for a team, no?) ready for a solid division I team in his first year, so not to worry.

You want $20 on FSU/UF? You got it. I prefer American currency, okay? :p

Everything is run wide open if at all possible. Most of the time the trimmer is really only run at 3/4 throttle.

The clutch on a trimmer doesn't lock up until about 2/3 of max engine speed. Runing extra long line and part throttle will help make you a preferred customer at your equipment store.

Mower is always run WOT be it a walk behind or a 21". Trimmers WOT if it is advantages but there are times in thinner grass WOT would just wack it all to hell. Blowers, of course WOT specially with the Redmax 8000 oh the power.

Check the owners manual. Every mower manual that I've read says to operate the engine at full throttle when cutting.

WOT, that is what the manuals say and thats what i do, just off idle for clutch engagement, trimmers, blowers & all others,WOT that is what they are designed for. look at the old lawn boy or jac 2 cycle mowers, flip the switch to choke/on, pull rope to start and gov. control from there on, thats why they had such a long life span.

Not only that, not running at full throttle with 2 cycle equipment will prematurely wear out the clutches.

Mower, WOT
Trimmer, I do as little as it takes. I was told by a guy 30 yrs in business that only newbies/homeowners run the trimmers at WOT. Guess that's not the case.
I've learned I prefer less, as then you don't look like swiss chees after some gravel. ;)

I seldom run the ZD-21 Kubota at full throttle. Mostly about 3/4-7/8 open. Why? That much RPM gives me the cut I want at less fuel consumption and noise. Once in a while, I work in really thick grass, then I open the throttle all the way. Wide open accounts for less than one percent of my mowing.

Kubota advises, page 29, to "Keep the engine runnigng at full throttle for best results." I think that's good advice from a grass cutting viewpoint and if I mowed the White House lawn, that is what I would do. But I don't.

Lower engine speed is justified in my case by the rough terrain that I mow. The speed limit is my ability to hang onto the seat.

The oxygen is low where you live? I don't mind waiting for checks, but not for too bloody long!

Actually, FSU graduated a majority of their starters from both defense and offense, so experience is going to be an issue this season. Add to that the fact that the game is in Gainesville, and it does look like a tough game for the 'Noles.

Chris Leak is also a fine quarterback. I hope Bobby Bowden has someone with a hot hand for the QB and I hope that the FSU offensive coordinator, Jeff Bowden, finally has a few things figured out.

They usually are good games and boy is there ever a lot of bad blood between these two teams. This is one of those games that you almost expect to result in a fight each year.

Mower- WFO Run it like you stole it.
Trimmer- as much as it takes, throttle down for light cutting.

I run my throttle just high enough to get the job done! (And according to Ground Speed).

It is possible that your engine isn't getting cooled the way it was designed to be cooled, by the air flow around it at full throttle.
With most machines, ground speed is controlled by selecting a gear, or by the hydrostatic controls, not the throttle.

The engine speed controls the Blade tip speed. Higher blade tip speed, better cut. If you reduce the engine speed you slow the blades down.

that's what i thought.....never really experimented with the slower blade speed to see the quality of the cut though........

I just adjusted my throttle, and now it seems like its over revving. I didn't mess with the carb adjustments. Just the adjustment on the governor spring. It could be that I'm just not used to the higher and correct engine speed. But it dose seem like its too high of an RPM.

You SHOULD cut on WOT but I turn the throttle down to right where it is about to lose rpm's, so about 90-95% - Still has the rpm's, just not the backup torque when it gets in tall grass it chokes a little easier but it also saves fuel and prolongs the life of the machine.

That, and I turn it down in the rocks and the dirt and on very steep hills.

a few weeks ago i read a thread on removing the trimmer guard...i removed mine and since i have not had any problem with trimming heavy grass. it's great. now i dont even have to cut at WOT with the guard off.

but i need new shins. lol
