Slasher type mower

[John 13]

I have acquired a 26" slasher type mower, with 7 hp Kubota engine. Appears to be a locally (Perth WA) built machine about 20 years old. Currently set up with a single bar type blade to rotate anti-clockwise, (looking from above). Would like to modify the very basic chassis to add a discharge chute exiting to the right. This would necessitate running blade(s) clockwise, could then also use a conventional blade bar with two off the shelf swing-back blades.
Looking for info. 1. Could the single (appears to be 20 mm) nut on the vertical shaft holding the blade be left hand thread ? (nut is 30 mm across the flats)
2. Has the rotation be made anticlockwise so that the said nut does not loosen?
I have not as yet been able to loosen this nut. The bar type blade appears to be clamped to the shaft between two very heavy washers by this nut.

Help based on experience would really be appreciated.

Likley. Do you have a brand name for this slasher mower?

[John 13]

Has been painted darkish green, no visible brand or manufacturer. Evidently was at one stage used by a Bayswater equipment hire company.

Almost certainly a left hand thread. That would obstruct your idea to reverse the direction of rotation.

Like CB said left hand thread otherwise the blade will work loose... Put a socket on it and give it a turn, only way you'll find out for sure.

Anti clock from above is clock wise from below which would be normal direction if nut is accessed from below
Rattle gun and wd40 may be required after 20 years of operation
Assume this is belt drive and your going to try figure 8 on the belt which can cause belt to come off

As I asked in the deleted companion thread could it be an Alroh or Mey (likely if it is WA Made). If so, or in any event, posting a picture here https://www.facebook.com/MEY-Equipment-138415729608647/ might get some more information.

For some strange reason I believe it is made overseas, surely Aussie made would run a Briggs & Stratton power unit?
Kubota sounds everything Asian to me?
Especially the colour!

Cheers Mr W

OP said:

and Briggs & Stratton are US and more recently Chinese made. Alroh used all sorts of engines including Briggs & Stratton, Kubota and Honda. See https://jarrods-power-equipment.weeb...der-mower.html for example

A Big thankyou to all replies. Yes nut/thread is LH, 3/4". 10 TPI. In the end I chose to drill a series of small holes on one flat and open the nut up. Nut was quite soft, likely mild steel. (Not savvy enough to include photographs) The quote above and some research confirms the possible issue with belt flipping off etc. However immediately unable to source a replacement LHT nut so plan to make a new shaft with a RH thread. Could turn the motor around (putting belt slack side on top !) to run blades clockwise (looking from above). Lower shaft bearing needs replacement anyway. Next job is to remove flange from shaft, may be shrunk on or just more rust. Incidentally the machine sat idle in a shed for 20 plus years, don't actually know how much work it ever did.

I contacted MEY, while helpful, no direct help with replacement LHT nut, subsequently tried other mower and industrial parts businesses in Perth without success.

A nut that size and spec, may be cheapest to reproduce on a lathe, using a cheapish (relatively speaking) tap. A quick browse saw one for $66 posted.

Everytime I come to this thread I think of the Bible!

John 13,

most center throw rideons will have one left hand throw and one right hand throw blade, greenfields also run left and right hand throw setups, try gaspares.com.au

i cant believe you destroyed the nut. have tried the mower manufacturer? or engineer supply.
its a Deutscher isn,t it, there good commercial mowers.

As he said it was made in WA and he contacted MEY I strongly suspect it is an Alroh.

yes, i check those two brands out, but they are roller/cylinder mowers. it sounds like a Deutscher . if the op said what it is would help. its becoming like , guess the mower, for me.

[Pis-ton broke]

a Deutscher is a slasher mower, and an old one might of used a kubota on it.

[aussiblue]

Alroh made all sorts of mowers, turf equipment and similar items. Yes they are best know by the home gardener for reel mowers but they produced a diversity of products trying to survive against the imports.

For example, this is an Alroh :

Interested to know more about the self propulsion. How from the engine out shaft particularly and engage/disengage mechanism ?

the attached pic is my Deutscher.
Usually painted in green, I re did mine in black, so it goes faster.
Actually used POR paint as it looks good and is better wearing.

It is many years old, but just keeps on going, and cutting like a beast. I have a slasher behind my tractor, but the Deutscher is great for the difficult areas, including under trees, and on rocky ground where it can get in close.

It is very tiring to use, although it is self driven, it is extremely difficult to turn and operate.

I ignore common sense and operate it with the guard open, as it throws out lots of cuttings. With the guard down it tends to jam.

Parked alongside equally old, but reliable John Deere.

Told ya!...a week back!

But it almost certainly an Alroh given the OP said WA made and they made a variety of slasher mowers albeit their reel mowers a more well known.

the op says " it Appears to be a locally (Perth WA) built machine" i don,t think he knows. was there a sticker on it? made in wa. made in stickers normally show country of origin.
but it sure might be a Aloh. we should take bets.

A photo would be nice, I'm intrigued as much as John:13 is!
