Deutz Allis Ulitma 1920 Mower Deck Question

Hey all. I recently bought a really nice Deutz Allis 1920 with the 2 stage snowblower, plow, 60" deck, rear tiller, 2 vac/blowers with the matching trailer and a fertilizer spreader. The snowblower worked great this winter! Now it's time to swap over to the mower deck. Its a 60" deck with the curtis gear box. I always prefer to change all the fluids that I can on used equipment. I have not found any info yet on changing the oil in this gearbox? How is it done? What oil to use? Really looking forward to running this deck and leaf vac to clean up all the leaves/sticks on the property!

Thanks guys.

I think that your Deutz is the same as my Simplicity Sunstar. The gearbox on the deck should take 80w90 gear oil. There is a plug on the rear side that can be removed and filled until it runs out. I just refilled my Sunstar before putting on the deck. Just turned it on its end and let the oil drain out. ( I just bought the Sunstar several months ago. These are fantastic tractors. Really built well. Herb

So it's really that easy, huh? Thanks herb. I'll take a look for that plug. Little allen head I assume?

Gearbox oil fill is a square plug. 7/16" I think.

That's interesting. What did you use to remove it?

In your journey with the deck, if you find that the blade belt is too loose, check the outer idler pulley by the discharge for it has two positions! Mine was maxxed out to the tensioner's bump stop but after switching pulley position it tightened it up nicely.

I always keep my eyes open to see if I can find one of the 1920's, almost bought one when I purchased my 318, and still wish I'd bought both!

Current Machine JD 322

Former Machines: JD 318, JD 216, JD 212, 1965 JD 110
