Message Board - Machinery: Greensmower height adjustment clicks
15 Oct 2007 by JessicaWabbit
Does anyone know how much the cutting height is adjusted (in mm's) by each click on a Dennis FT and/or a Paladin?
Ta mucho!

0.5mm on the FT, same on the Paladin I think.
Of course there's no bounce, bend your back and put some bloody effort in.

The man from Lloyds spoke to our groundsman's assoc meeting this month and I'm sure he mentioned clicks on the Paladin. Perhaps only on new models???

Then again it is such a God awful machine, it's virtualy impossible to persuade any member of my staff to use them. Who an earth ever came up with that gear ratio!

Your not planning on making a little copy to the some new mowers are you Vic? lol

Please don't. Clicks are OK for quick adjustment, but they're a pita to get the damn machine perfectly level with - especially I'd imagine after a few years when there's wear in the thing.

The only way to set a mower accurately is with a height adjustment bar. Across both rollers and the top of the bottom blade and checked along its entire length. As wear takes place there will be descrepences between each side of the machine and these need to be adjusted independantly. Clicks are alright in a DIY machine for a domestic lawn but in the proffesional world greater accuracy is required. If anyone has seen a golf green cut with a mower half a mm out on one side will know what I mean! It looks awful!

My thoughts exactly Chris.
Whilst 0.5mm adjustment is fairly fine over time you may well need finer adjustment than that and on a machine costing over 3000 I expect a fine level of adjustment. 0.5mm isn't good enough imho.
Of course there's no bounce, bend your back and put some bloody effort in.

Exactly John. Still don't know why Toro use a click wheel for bottom blade to reel adjustment. As soon as things start to wear it involves resetting the whole thing with a cam at one end.

Interesting thoughts guys....thanks!
We are just looking at it ~ don't fret though, if it is introduced it'll be an option, not a standard feature.

My Paladin definitely has a single click adjustment on it.

Hi yah Chris Mitchell,
Just read your post advising that HOC should be checked throught the length of the bedbar. Just supposing it was a little out in the middle, how does one adjust that?
Regards
Cal

calcallaby , one regrinds cylinder and bottom blade because both should be accurately straight. If this is not the case, the chances of any accurate adjustment are next to nil!

Sorry I haven't come back on this one sooner, had some IT problems Sunday morning and have been computerless until this evening (Monday).
It's nice to hear that you still employ your grinders Chris, even if it is in a futile attempt to get your mower's HOC correct all the way across the bedbar.
I use an accu gauge to measure HOC and if I am in any doubt about a machines HOC all the way across the bedbar/bed knife I turn the front roller (this is the most vulnerable) to check for bends. A bend of just a quarter of one millimetre will give a height anomaly of one half of one millimetre and when you’re down (way down) in heights of cut you know as well as I do Chris, everything shows up. A twenty-one inch roller struck in the middle by poor loading or rough handling is fairly easily bent and we have had a few over the years.
You can spin grind a solid whiele roller made of steel on your Express Dual but unfortunately not one made of aluminium, although your local machine shop would have no problems. The obvious alternative to these two options is to fit new.
Next I would turn the rear roller(s) to see if there is any run out that is significant enough to condemn a centre support bush/bearing/shaft and address any problems found there, as found on various generations of Toro Greensmaster 1000s for instance. Or in the case of a single rear roller, check for a bend and address as necessary, the Toro Flex 21” has such a roller.
Next I would check for the parallel of the reel to the rear roller and make any adjustments required and after that I would make my final HOC adjustments.
If I still had a problem then I would be looking for a bend in the bedbar, if one is (was, not sure now) found I would assess whether I could grind it out on my Express Dual or whether a new one is required, as a temporary measure I may pack it with paper AND THEN GRIND IT.
I think it is important that posters in technical forums should post accurately and give good advice don’t you Chris.
Kindest Regards.
Cal
