How to make a mower deck run in reverse

the twist is for a catcher I got some flat blades for my old Deutschher .........havent worried about the new mower yet .........my old 7' slasher was run the opposite way by Telecom .....Ive never worried ,the blades are 3/4'' thick and pivot at the spindle .......they are now worn half away from 40 years use.........anyway ,it needs a bit of rust repair.

To solve the problem of the nuts coming off, can you replace the vertical spindles with left-hand threads?

Or drill and split pin.

For me I'd keep it simple ...
Why not just put the belt on as a figure of 8 instead of likely normal ... I reckon you'd need a small idler pulley to stop the belt rubbing on itself ...

But as one of my old bosses once said ... " What would you know ... You're only a truck driver"

So far I think reversing the deck may work.

Also making new blades.

The blades would need to drop at the ends or I'd have little trails left behind by the spindle and nut.

Lang's is a good suggestion, split pin the nut.

I'll try the turn the deck around on paper and see what happens. Won't be today but tomorrow works.

The belt runs between the gearbox and middle spindle is too short the to twist the belts.

I'll pull the side of the box and see if the spindle gear can be flipped to the other side.

I agree the cost of building a CW or CCW box would be a few cents more than just one direction.

I could also use a flat steel bar with normal (Victa style) blades bolted to the ends.

You guys are good.

Reversing the deck won't reverse direction of the blades.
x2 with Lang, split pins is the answer.
I too suggested putting a twist in the belt to get it to rotate the correct way.

Twisting the belt is a toughy.

The distance between the gearbox pulley and the middle spindle is about 150mm.  This is a serious belt and I don't think it will like having a figure 8 put in it.

Still yet to think about  turning the deck around.

If the belt is running on side of the pulley nearest the driver and it is travelling from left to right 

If the belt was to run on the othe side of the pulley wouldn't it then from right to left ?

I dunno, I would need a sheet of paper and start draw things down 

Anyway back to painting walls for me
apparently Christmas is coming and the house renovations aren't Christmas ready enough yet

Nothing makes sense.

I've searched high and low.

The blades look correct. eg:
www-ebay-com-au/itm/301927782171? and all the other sites have the edge on the side as the photos.

The PTO cannot be reversed. Simple electric switch clutch  and gear box driven.

There is no metion of reversing the PTO in the operators manual.

The photo's look like the mower is original, except there is nothing about the gear box.  But the welds, brackets and the like all look original.
So, where is the reason for the reversed rotation?

I still think it's inside the gearbox.  If it was me, I'd pop the front cover off and have a look for a reversed component. An hours work?  I've spent more searching.


Imagine this,  the gear box is apart. And the boss simply says, " ahh, just assemble it and sell it".  So the kid puts it back together send sends it to the auctions.
 

Silly question,
are you sure it's running in reverse?
