Zam Special 1500

Anyone got an idea of the disc I have and the spreading charts for nitram.

 

[robbie]

Os 10-18
They do cross reference with the later OM discs in the amazone app, I think they're now called OM 12-20

When setting the disc veins am I looking at the inside of the veins for the number or the outside ? If u get what I’m saying

the sharp single edge.

 

[Seth470]

also what pto speed do i have to run ?

 

[robbie]

Always at 540 rpm unless the book says otherwise but that's just for dust to ridiculous widths.

What is the difference between OS and OM discs?

In the app it says disc speed should be 720

I'm not sure the app will take account of the amount of rust on that disc!

I have an old ZAM setting chart book for OS discs. Your discs look like OS 10-18. What width do you want to spread at? At 12m the vanes should be set at 65/90 and at 18m 67/92. the end tips should be in the lower position.
For Nitram, disc height should be 80 cm plus half the height of the crop. The spreader should be level front to back and obviously side to side.

Just noticed the settings in my book are slightly different to Robbie above. Mine came with a 2001 model year spreader. The OS discs on mine were stainless.

My Amazone hydro has a disc speed of 720 rpm but I would guess that a Pto drive will be 540 shaft speed to give 720 disc speed..
