OutdoorKing Repair Forum Forums Finding and Swapping Rare Finds & Donations Victa Blade washers

Yes, but those aren't Victa thrower blades - they are stepped & fluted, and the Victa ones were only fluted, IIRC. The thrower bolts are correct I'd say - Victa used the same bolt/washer set for both cutter and thrower blades on these carriers, with the bolt head on the blade side of the carrier.

The Belleville washer is installed incorrectly on that cutter blade set, though!

Probably a bit of forward planning on Victa's part, to reduce the number of different carrier types, and hence reduce warehouse and dealer inventories.

No practical advantage to fitting them, on a non-catcher deck. This is due to the thrower blades being set higher, so they don't do any cutting.

Four blades are better than two, if they are all at the same level, though. My SupaSwift Big Bob handles heavy growth better, and leaves a better finish, with 4.

Yes Gadge, Id have to agree with the forward planning, as Victa was often ahead in designing its future models at or before the release of prior models. The 9C carrier was NOT ever meant to carry 4 blades at once. The 2 level holes for Rotomo,Special etc...and the raised blade points for the catcher models. So one plate fits all. Thankyou for your thoughts.

And yes of course 4 blades are better than 2 at a level height. I also use four blades on my own mower and it makes a huge difference.

I'm aware of the 9C carriers function, Im far more interested in the questions from the prevoius post and also the following. Im looking for accuracy of fitment.

The Model 1 Rotomo used a different blade plate than that of the patent variant. At this point its my opinion that they possibly sourced this plate externally and modelled the Patent Carrier from this.

They are similar in design, with a few additions made to the Patent version.

This is why Im' asking when the patent was approved for production, to ascertain when the Patent version was fitted, and to which model.

From the the release of the Model 1 to the Sheerline I have found 4 plate variations

Model 1 (sample image coming)
Patent carrier with Humps...9A?
Patent carrier with no humps 9B
The Multi point 9C

The 3 Patent style humped carriers I have are on early to mid model 2 Rotomos.
All the rest are 2B carriers.

I remember you (Gadge) saying you used to change all the 9B carriers for the 9C for ease of fitment. What confuses me is...Ive never had a Special with a 9B plate. Does this mean they changed every one? I cant see it.
My point is, in your opinion what year was The 9C carrier released and is there any documentation?

Cheers.

Every dealer-serviced one would have been changed over I'd say, purely for cost [and convenience] reasons. Victa's dealer price for the 9C carrier assembly [with fitted blades] made sure of that. Even at the hourly labour rates we charged back then.

Doesn't mean that no originals exist; just that they will be about as common as rocking horse dung. And most likely to be found in areas remote from servicing dealers.
Can't help you with any evidence for that, I'm afraid; our family OPE business started in 1973. The carrier/blade set swap was the go then, though we still had legacy 9B carrier parts in stock, as we took over an existing business, founded in the 1950's.

Hello Gadge, HT6 and viewers

As I understand it, the Model 1 was the first machine to use a disc holder.
Prior to this, there was the bar and swing-back blades.

I do not know when the 9C was released. Best guess c1959 - just before
the release of Victa's catcher models.

A Note on patents:
As I understand it, the Model One was introduced in about April of 1955.
From my experience, patents generally come after production begins.

The second point is that illustrations accompanying patents are just that.
The illustration does not form part of the patent as such , it just illustrates the
words that do. In production, they will vary, but follow the principles detailed in
the patent.

Victa could clearly have used slight variations before settling on the
replacement blade holders - the 9B and then the replacement 9C.

The 9C was designed to take 4 blades for catcher models.
These were the 9-172 and 9-173 assemblies.



The interesting thing for me would be the recording of the ramped holders.
I am unsure whether the 9B had ramps at all...?

Cheers.

This is What Im trying to work out Jack...

What was the Pt no for the Ramped Carrier in the patent? I know it was made per the diagram as they are on some of my mowers.
For now,I can only assume 9A?

And yes From What I know the 9B is just plain.

So Im assuming the ramps were dropped fairly early then.

Ok so Im not going to alter my early Model 1s, use the ramps on the late 1s, transitionals and early model 2s, and keep the 9B For the rest.

Sounds close enough for now.

Thanks for your Input Guys.

Hello Mal,

I have nothing but the Green Books for part numbers.
Part number for the ramped holder? Probably lost to history.
The main thing is that we record Victa's first disc.

Shall we call the first disc the 9A?
So, at what point did this 'ramped disc' give way to the 9B? And why?
Here is an extract from a late 1950s maintenance guide. 9B.
[Nice way of removing the disc nut]



Cheers.

Or Victa may just have regarded the change as a supersession, and used the same part number for both versions.

There was no provision in Victa's part numbering system at that time, for designating such changes during production. That came much later [1970's], with the XXnnnnnX format part numbers, e.g cutting blade 9-150 became CA09150S - the letter suffix can be used to express supersessions, and I believe that's its function. Edit: or one of its functions - the 'S' suffix denotes a skin packed pair of blades.

For comparison, Honda motorcycle part numbers always included both the model the part was first used on, and the supersession.
E.g. in P/No. 22870-MG7-000 the first 5 number group describes the part type [in this case, clutch cable]; the second 3 character group is the bike model designation [XLV750R]; the third 3 character group is used for supersessions, paint colours etc. For items specific to exports to a particular country, Honda uses a further letter suffix [U for Australia], but only on those specific part numbers.

That would work OK with the 9B carrier [remember, the brazed in bushes protrude a long way above the disc], but even then, I'd prefer to use a square shank screwdriver!

The other traditional method, that of hitting the spanner with a hammer, would be less likely to cause the cracks often seen around the bushes, I'd reckon. This cracking would be another reason for most 9B's having been changed out for 9C's, when these were everyday working mowers.

Good pic of the 9C Green Book page Jack; it shows the difference between the thrower blade types very well.
