Flat and True and the mower is set for the lowest cut.

Ok, are you using a setting bar to measure your HOC?
If so what hight have you got set at on its lowest point?
Sumo asks a fair question as he may know what bedknife you may or not have to get the finish your trying to achieve?
ADDED
Photo`s also help?

Go to a good mower dealer and get yourself a setting bar - a couple of £., like the one mario shows on your other page!
"Please" keep to the same page also., You have two on the go.? photo`s make a big difference.
You can`t trust the settings on your mower, not even the newer ones. eg your setting, say a final cut to a track? With a ruler! measure from the bar to the bolt head that sits on the bedknife? (mario`s photo) say 4mm? Then sit the bolt head on top of the bedknife in the middle of the cylinder to start with. Then gently lower the roller on to the bar and hand tighten roller retainer bolts from both ends. Then set the bar the same way both ends of the bedknife & tighten with spanners when you have the same hight on both ends? job done.... Practice makes perfect....
One more thing, Check roller for any play in bearings and dents on roller? as this will need to be put right before you do anything?

A setting bar is a must on the certes, I defy anyone to guess how much to change both ends by eye accurately, especially when changing the hoc by a couple of mms or so.
What do I do? I just cut the grass.

no no, would never say that, ;)
I was going to suggest if you where anywhere near preston, lancs i would of come around and shown you how to set the HOC with the bar. But cornwall is a bit of a trek.

Barry, some certes have a single point adjuster on them - I know mine did. My adjuster only allowed down to 12mm though so not a lot of use for cricket. It'd been on there for 5 years so I guess no one ever used that machine. 10 minutes, a couple of bolts and nuts and the adjuster was gone - destined to be buried somewhere at the back of the workbench.
Any one care to explain why you'd fit a shaver blade to a machine that can't cut lower than 12mm ?
Without the adjuster it is impossible to set level without a setting bar.
Of course there's no bounce, bend your back and put some bloody effort in.

Thats why they got taken off because of that reason.
I`ve done it myself. My old mentor would get out this straight bar disappear into the clubhouse & comeback out with a beer matt! Cut it to the width & tape it to the bar. Give it a quick squint Then pass it on to me and say, there you go son, that`s the height i want you to cut the track today!! 
Dont make beer matts like they used too, if they did they would be the best cut wickets in the world....

Not looked at this post before. Is something missing?
BTW, forget beer mats, imo - look at the track after you've cut it. If it looks too long, it is - wind the mower down a notch. If it looks right, it is - stop. If it looks too short, stop - and go slower next time.

Yes jt there were two threads going at same time.
Beer mats was just my sense of humour kicking in. Although true! wouldn`t reconmend it, looooooong time ago when i was a snotty 16yr old apprentice. Stick to the setting bar and ruler and get it right first time.....

Yip, a setting bar is a must for accuracy.
I know no boundaries.

Excellent illustration mario.
But got to ask! - Where are you positioning the camera to take photo!!

Ha, ha!!
But to answer your question, it was mounted on a tripod with the self-timer switched on and not strapped to my forehead!

Easiest way to accurately set the screw is to get to Lidl/Aldi and pick up a cheap set of digital calipers - you can pick em up for about 8 quid.
Of course there's no bounce, bend your back and put some bloody effort in.
23 Aug 2010 by mario
Agree with the caliper suggestion which is what I progressed to from the ruler and bar. I now use a setting bar with an analogue dial guage.

The guessing game doesnt work for me. Ive staryed leaving a bit more grass on as the season gets on and the pitches get a bit barer and I know that by using the setting bar I am just leaving an exact amount more. Even if you have a single point adjuster, why guess?
What do I do? I just cut the grass.
24 Aug 2010 by A J
Agree, Guage & callipers are more accurate.
However, We have a habit of leaving bar`s & rulers in grass boxs when transporting mowers from square to square. And have been known to end up on the compost heap from time to time.
Fortunately, being a school we have endless supply of rulers!!

LOL, glad it's not only me who's had to dig the bar out of the grass heap a few times. Not managed to bury the calipers though.
Got plenty of metal bar lying around, all it takes is a drill, screw and a tap to make a measuring bar - it's always handy to have a few spares.
Of course there's no bounce, bend your back and put some bloody effort in.

I use flat timbers and self tapping screws, simples.
