souping up a lawnmower

Is it easy to do this?
My plan is to remove the catcher and rake up the grass afterward manually.
(As there is little more mind numbing than walking behind a slow mower)
I reason that without the catcher the motor shoud be able to run faster without overexertion.
So could I get it to go as fast as I could follow? If I had to run it wouldln't worry me too much as the job normally takes me up to 5 hours and if the grass is wet it might be longer or even impossible.
I also don't worry too much about flying stones as I don't have any litigious neighbours

Removing the grass catcher and installing the required deflector or chute would definitely increase the mower's ability to discharge the clippings, making it possible to go faster.

I just gotta ask....... How many acres are you mowing with this thing ?

Is it a push or self propelled mower ?

I hate to admit that I have even removed the deflector chute from my mower. Letting the mower deck easily shoot the clippings out really helps it's performance in wet grass.

I don't know how many acres , especially as the job is made up of 6 or 7 segments.But the largest of them would be about 50 to 70 yards in length by 150 to 20 yards wide and this would be about the size of all the other smaller areas together.
It is self propelled , although that wasn't always the case.
Is souping it up a difficult job.
I don't plan to do it myself but , if it was a good idea and not too costly , then maybe I could get it done by someone with the expertise.

There really isn't any souping up that can be done on these small mowers and have them last. Removing the grass catcher will help as mentioned, Most of these small WB mowers come set at 3200 RPM's. You could have the RPM's set up to 3450 which would help a little more but I wouldn't suggest any higher.

Have you considered getting a larger mower? This souping up you want to do will cost money better spent on something bigger in my opinion.

Get a different mower, if you mess with this one too much you're going to blow it up anyway and may hurt yourself or someone, then you have dr bills and no mower, ain't worth it. Have a good one. Geo

i have seen only one small engine head, so i don't know if they all are like this, i expect so. the ports were VERY poor. by HOT RODDING standards, hideous ! so, if possible, doing some porting would help.

but, as was said. get a larger mower. if it were me. i would get a nice rider, with a cooler full of beer on it. and make an event of it. turn a lemon into lemonade !

Size of mower and getting to it before it gets to tall are the only changes that are worth considering in this scenario.
Bagging doesn't slow mowing rate down. It's the same as discharging.
If that's what you mean by "catcher."

I used to not be litigious with my neighbor until they took advantage of it and finally broke my basement window by constantly mowing their lawn with the safety chute removed despite me asking them not to in the front were there is no fence.

I meant I don't have near neighbours in the first place.
My idea about taking off the bag wasn't to speed up the motor but to allow the motor to operate at higher revs without overexerting.
It is difficult for me to get a larger mower than what I have as I am in Ireland and I don't want to get a ride on mower as I have some low and fragile stone walls that I lift the mower over
And the lawn is uneven too.....

Many years ago I had a Zosia grass lawn and my mower was without throttle adjustment(5hp briggs) would bog and die so I tied a string to the governor and whenever I was ready to put the mower in the grass, I would pull on the string, when I got to the end of the lawn I would let go of the string. The mower lasted 5 years and smoked and hammered, I don't know how much longer it lasted because the wife(at the time) kicked me out. However, it is an option. Have a good one. Geo

that doesn't increase the speed of the machine (I mean the wheels , not the motor speed or the cutting speed ) .In my ideal world I am prepared to run behind the machine to get the actual grass cut and then spend an hour or so raking up the grass and carting it away.
I do have it set high anyway as I have about an inch or so of moss or other debris sitting on the top of the soil and if I cut too close this gives the lawn a nice browny green splotchy effect.
The amount of rainfall we get makes it fairly impractical to get gid of the moss (well I am sure someone with a lot of time and determination could do it , but not me)

Keeping the blade sharp will help performance.

You're still mowing about 5 to 51/2 acres of grass using a push mower.

It takes me 45 minutes to mow 1/2 an acre with a push mower.
Let's say you jog and take only 30 minutes, and use only 3 hours.
So after jogging behind a pushmower for thee hours, you'll need to rake up 5 1/2 acres of lawn clippings using less than two hours for this to work out as a better approach.

Depending on the type of drive system on the mower but if is belt and pulley, to get more speed you need to increase the size of the pulley on the motor and decrease the size of the pulley on the transmission. Have a good one. Geo
