HSCS
HSCS is the short cut of Hofherr-Schrantz-Clayton-Shuttleworth, a fusion of a austrian agricultural machinery producer Hofherr-Schrantz and a british motor maker Clayton-Shuttleworth. The Company HSCS is mainly known for Hot-bulb Tractors, which are like the german Lanz-Hotbulb tractors.
I also want to show, that until 1938 it wasn't a Lanz license construction and no Lanz replica. It was a direct competitor for 'Heinrich Lanz Mannheim'. The alikeness to the functionality is because of the 'state of the art' that time, the lying single cylinder 2-stroke fuel-oil hot-bulb engine. Like all locomobiles from different producer were alike.
1938 undertook Heinrich Lanz Mannheim the majority of the HSCS-Shares and displaced a part of his production to the austrian factory, whereby nothing changed for the hungarian factory and the tractor production.
1948 was the HSCS factory in Budapest nationalized by the Rákosi government. The production was going on under the name of "Vörös Csillag Traktorgyár" (Tractor factory Red Star).
1969 was a fusion with the Trauzel-Werk, whereon one year later the acquisition through the Böhler-Werke was following.
You can find a detailed Company history under: www.gluehkopfbulldog.de
The purchase
After the 2. Worldwar all tractors were fused in through the communists for the feedstock extraction. This means that a 'real HSCS' is a very scarce and expensive collector item. Rumor has it, there are only a few single models in Hungary, which were greased and buried by there owners. (apart from the export models)
The alternative
Alternative there are some 'Red Star' tractors standing around and waiting for their restoration. They are relative affordable and through the unchanged construction, they didn't lost there 40th year flair. A major difference between the pre-war HSCS/G-35 and the postwar Red Star/GS-35 is the affusion cock from HSCS and the alloy cock from the Red Star tractors. So the Red Star has a higher stand gas engine speed.
Wattles of the restoration
The restoration of a hungarian tractor is difficult because of following reasons.
1. There are as good as no reproduced Parts, as for example Lanz or Deutz
2. Owners of tractors or spare parts, know the value and how rare they are
3. To get a export permit for historical vehicle from hungary is very difficult
and normaly you need help from hungarian friendships
4. Because of the 'German Industry Norm' (which is not true for eastern europe),
there are a lot of different thread and bearing sizes.
5. Rumor has it, was the original literature of the HSCS factory in Budapest
destroyed. So the purchase of manuals, repair- and operating guedelines and
the translation are very time consuming, difficult and exhausting. I have to
allude that export literature in english are existing.
6. Through the nationalisation the care of the most tractors was very less,
Some interesting
"The betrayer"
The tractors, which were used for war intentions, were named as "betrayer".
Understandable, because it's very difficult to bring materials with this large-volume
hot-bulb unseen to the front.
"The biggest!!"
Nobody knew, with the model K-50 build HSCS the biggest one-cylinder hotbulb
tractor of the world to mass (14,8 liter cylinder capacity!!!!!!)
"HSCS smoothed away"
After the nationalisation and renaming from HSCS to Vörös Csillag
Traktorgyár, the existing HSCS- .... were used from 1948 until 1950.
Only the HSCS letters were smoothed away. 1950 new ... were cast, but this time
without letters, for it with a area for the new Company shield.
"The last hot-bulb"
1985 build a hungaryan company the TS-35. The TS-35 is the last hot-bulb-tractor
of the world ! (except the Lanz replica from poland)
A revitalization test (I'm still researching), there were only build 5 tractors
and rumour has it, now only 3 of it exist. (I made a photo of one of it in hungary!!)
The TS-35 is based on the GS-35. They were only different in their casing.
"The vienna HSCS factory"
Facts about the forgotten vienna factory:
Near by the procution of agricultural machinery and tractors, there were made
machinery for the paper industry.
The vienna HSCS factory (the "Proud of Vienna") extended to 202500m²
, had a own generating station with 1700 HP, produced with over 1600 tools-
and work machines, had the biggest casting house of vienna and engaged from
time to time 320 employees and 2500 workers.
Unfortunatly, I have only one bad picture of the factory, so if you have any
information or pictures please let me know.

"Porsche-HSCS"
After the second world war, the Böhler-Werke bought the austrian Hofherr-Schrantz-Werke.
They produced the little Allgeier/Porsche-Junior as Hofherr-Schrantz (licensed).
The most parts came from Germany, only the axle and the frame components were
build in vienna, but I don't know it excatly.
Spare part acquisition
In the course of time, I met HSCS Owner from all over the world. There are some several spare parts at single collectors. There are some collectors, which let parts re casting and extend this for sale. Most of this spare parts dealings are on change basics.
