Hi Frog, welcome here, the blades are 140mm end to center, they are the same blades they used on the Super 24's they just used a smaller blade carrier on the 550's The ODK store may have them, otherwise ebay under Victa 24 or 600
Hi Frog, I assume this is the 550 you are talking about. I have to put a set of blades on this one today. Many years ago I had a mate called Tadpole and when I asked him why he was called Tadpole he said it was because he wasn't big enough to be a Frog
Hi Frog, a few questions about your blade carrier, does it have 4 blades as in this pic and what is the bore size of the carrier? What is the purpose of this mower, do you want to restore it to original or do you want to use it as a mower? I do have a lot of various blade carriers here if you need one seeing you are in South East Vic somewhere.
Blade carrier is like the first pic, actually have a few of these style mowers now, 2 are running. Got hooked on them after getting the first one. One of the other mowers has four holes in the blade carrier, with only 2 blades on and the other has just 2 holes. 13mm holes. Both have different style blades on them, hence me trying to find the correct ones.
It is my everyday mower.
I got the first one years ago from my old man, never really used it much, bought a newer mower and when that packed it in, used the utility and loved it. So bought a few off ebay, played around and got them running ok. Though must say I don't really know what I'm doing, just disassemble, clean, put back together. This forum helped along the way.
My son just bought a block of land and I want to give him one of these utilities to keep the grass down.
Would love to restore one, have seen what you guys do on here and they look great, but as I said, don't have the nous.
I'm on the south gippy highway, just past Cranbourne.
Frog you are just up the road from me, I'm in Hampton Park. Any of these 2 stroke Victas are the dux nuts, people have forgotten just what turned grass into lawn in Aus all those years ago. Since then they have been conned into believing four stroke is better. For mowing a block of land think about a 24 with a 2 stroke on it, you will be amazed at how well they handle that sort of work. The utilities are good but for jungle work the 24 is brilliant. I have truckloads of 2 stroke stuff here so we can keep your mowers going till your son is an old man
The correct blades for the 1968-69 Model 550 New Utility [assuming it still has its original blade carrier disc] are Victa P/No CA09262S; THESE - these blades fit on top of the carrier, which looks like THIS.
As you say, the New Ute in that pic has a non-original air filter; this model used a 'short' type.
NormK's second pic shows the Type 9C blade carrier used on earlier model Utes, where the cutter blades were flat, and mounted below the carrier. This carrier could be fitted with a second set of 'thrower' blades, which were mounted on top, but the Utes didn't have these.
It might be worth grabbing a few spare sets of blades, as it looks like this particular type is no longer supplied by GA Spares, who are one of the two major aftermarket parts wholesalers.
Cheers, Gadge

No worries Frog, I'm here most of the time. Maxwestern picked up most of the earlier 2 stroke complete mowers I had here but I still have a lot of motors and bits so we can keep these 2 strokes going for years to come and I am always chasing around after bits. I will PM you my address
