Hi all,


I have a LH throw Greenfield deck here and i am just wondering what models they used them on. I was wanting to look up a parts list or manual to work out how they drive the deck anti clock wise with a clockwise spining motor.
If someone could explain it to me even better.
If they could snap me some photos of the offending setup they might even get on my Christmas card list.


Cheers, Bob.

I may actually convert my old tractor to a setup like this as it could well be easier than replicating the clutch on the front of the motor.

Love the pic Bob, I'm guessing it does not really have a blue belt that eats red pulleys!

Not that I can talk, I had to upload a hand drawn sketch to my cut out pin thread, every diagram i tried to do on the computer looked like an evil hamburger!!!

Yeah i know, ive got awesome paint skilz

Better than mine, I see no angry food!

Bob, that setup requires a double-sided V-belt, which is not a commonplace item. (Unless, of course, you twist the belt on the two long runs. That is likely to have an ugly effect on the belt life.) Also, remember that the spring-loaded belt tensioner pulley has to be on the return side of the drive pulley, not the drive side.

A technical point about reversing drives:
Getting a drive reversal with a single-sided V-belt, without using a friction or gear drive to do it, requires twisting or crossing the belt. I can only think of one reasonably elegant way to cross the belt: the Greenfield system for wheel drive. Unfortunately even Greenfield messed it up. They put their automatic belt tensioner in the one place that has to carry full drive tension when you reverse the mower. To make that kind-of-work, they put a ratchet on the tensioner, so it can't dump the tension and slip whenever you reverse the mower. However the ratchet has to have some distance between notches, so it sometimes doesn't quite make it to the next step, especially when the pulley mechanism is new and fairly tight in its slide. As a result you sometimes get belt slip and have to lever the tensioner pulley along its slide to get the ratchet into the next click point. Good revenue for their service centers no doubt, but annoying to owners.

Not sure exactly how it works with the belts.


Im hoping someone will front up with some pictures.

I think i see now how it works.

Hi Bob,

I think the above photo is of the drive belt set up. If a LH throw is on the left when you sit on the mower then its the same as in the Greenfield Idler Pulley and Belts thread. So for the benefit of others who've looked at this thread I've attached a couple of photos of the mower and the cutter belt run.

Thanks heaps for the pics.


Looks like a fair bit of gear to buy or make up. Might just be easier to sell the deck than use it. Or buy a mower it will fit thats missing its deck.


Heres the offending item.





Looks like it might be a bit different to the above. The pulleys on the under carrige rather than the deck.
But ive got the idea now.
