third party image

I read with interest the story of the Case cab development in the recent issue of Old Abe News.
I recently saved a picture from the internet of a 930 cab being tested so I thought it would be
a good addition to this story, only it does not fit the time period since its labeled 1970.
I have to presume the date is wrong since the 70 series factory cabs were already introduced in '69.

So I'm wondering if this was a cab tested in the mid-60s for the 30 series before it was decided the Allen cab would be the cab sold through Case dealers for it's 930s and 1030s? But did anyone care about roll over protection at that time since OSHA didn't require roll over
protection yet at that time?

Or was this the after-market cab mentioned in the article being tested for the up and coming 70 series that failed so miserably that Case then decided to design their own cab? I think it's possible a cab would be tested on a 930. A 70 series tractor may not have been built yet in time for the testing and development of a 70 series cab.
I should think this would have been taking place in 1968 to allow time for design, testing and production of cabs for release in '69 but I'm just speculating.

On another note, the pictures in Old Abe don't match with the story timeline either since the tractors on their backsides are both Power White tractors, the first being a 1370 and the second an 1175 which didn't come along until years later. But the film stripe pictures look like Desert Sunset paint and painted fuel tanks.

My guess would be that the "demonstration" was conducted by the Agricultural Engineering Department at a Land Grant college like Iowa State University at a field day. I know for a fact that they did a lot of testing and development. I have some similar photos of John Deere's (4020's, 4320's) being tipped over with "human like dummies" attached.

Didn't they also do pto demonstrations? Where the dummy gets wrapped around a pto shaft?

My take on this is kinda on what you said Brad around 1968, as its a 30series, and they are starting to test cabs they might buy, as they knew at that time ROPS was part of the makeup for the 1970's.

It's really something when you think about it. The after-market cab was a booming business, and it all come to a halt in a few short years for most of them.

That picture brought back some scary memories. I tipped a 88 Oliver backwards when I was a teenager. I had no idea it would tip rather than spin out. When that front came up it dumped me out of the dishpan seat and I hit the ground running like a jackrabbit. I was probably 100 feet away before I heard the crash. Scared the bageebies out of me. Dad was both mad and happy at the same time that afternoon. That along with a near rollover of my loader tractor in the 70's convinced me - I've never had a working tractor without a ROPS since. ADB

Glad you survived. My Gramps had an Oliver 88 Diesel Standard. I had a cable hitch on a spring tooth digger crawl up the tire one time when I turned too sharp.
That scared me a bit when that digger started crawling up after me. That Oliver was a great tractor except for the lack of power steering. If you turned too sharp the wheel would spin out of your hands on a turn and about bust your fingers.

Could the picture have been taken at one of many farm show safety demonstrations rather than at a Case testing site? All the glass has been removed from the cab, the engine looks to have a gasoline carburetor, no drawbar or 3 point hitch and the treads on the rear tires are far from new. There are side plates reinforcing the rear of the fuel tank and a frame protecting the front of the tractor. The rear window frame and the top edge of the cab appear to be already damaged.

I wouldn't think so but I have no idea. Maybe they did a demonstration for dealers, but I can't imagine the liability of rolling a remote controlled tractor near a crowd of people. And a gasser to boot! I'd think a diesel would be far safer from a fire hazard point of view but again I'm just surmising. I suppose a gasser would be easier to kill with a remote switch.

The Old Abe article did mention they had to pull the drawbar and 3 point arms off to get it to upset otherwise the tractor just sat on its hitch. I can imagine they didn't want deep tread on the tires in case it dug in and spun around as it tipped.

Forgot to add they used a non- ROPS cab in those demo's to show what can happen to those cabs,,, it was a Very effective way to show you how much ROPS was needed in a upset

Those steps would not be much fun to climb, would they?

Not really but they don't look much worse than some of those John Deere cabs I've climbed into. Ha
Those green cabs with the round doors are the worst. If you start off with the wrong foot, you meet yourself coming back out while trying to go in.

that is a Egging cab from what I can see,, the Allen units had been chosen long before this was taken,,, they promoted the need for ROPS in the late 60's as well as in the 70's, it was a big subject at the dealership even before the 70 series were talked about, I have several pics and slide films with early 70 series tractors, 69 models are what is in most of them, then later in 74 they did snap some new shots of the later color units

It makes sense to me they would want to re-test the cab on the bigger tractors anyway since the cabs were made different and the tractors were a bit heavier. I missed out on all the pics and films of the time. Our Case dealer had some VHS tapes of stuff but I don't remember them ever showing them to anyone. Many of them were service training tapes I think.
