Cornish-model-farm Posted October 15, 2023 Share Posted October 15, 2023 I always wanted to make a replica of the Crawford ploughing tractor (see first picture) which was an ex-WW2 Sherman M4-A2 tank converted for agricultural use by Robert Crawford, a Lincolnshire contractor in 1947. I have just assembled the running gear from a 1/35 scale Tamiya Sherman tank kit and the tracks move smoothly. Like Crawford, I have discarded the turret and side armour, which reduced the weight of the real tank from 35 tons to 20 tons. Crawford kept the twin General Motors six cylinder diesel engines, which produced a useful 375hp between them. There are no engines with this kit, so I will need to improvise. I also need to 3D print some new tinwork and add the two 9 inch diameter exhaust pipes! Having painted and weathered the model it is starting to look a bit like Crawford's creation. 4 Quote Link to comment Share on other sites More sharing options...

super6 Posted October 15, 2023 Share Posted October 15, 2023 A different farm model to the norm, look forward to seeing this completed. Would be relatively easy engine build if it had either a radial, Ford V8 or Chrysler multibank power plant. This would do you if you can track one down Tank Workshop 1/35 M4a2 Sherman GM 6046 Tank Engine & Engine Compartment 350059 sherman engine compartment - Search (bing.com) SHERMAN eng (strijdbewijs.nl) SHERMAN eng (strijdbewijs.nl) for your perusal.

The six air filters on the engine bonnet look impressive. Quote Link to comment Share on other sites More sharing options...

Hajo Posted October 19, 2023 Share Posted October 19, 2023 Really nice project on to go here! Never thought this could even exist, how does the size compare to 1/32 models? 1 Quote Link to comment Share on other sites More sharing options...

Never thought this could even exist, how does the size compare to 1/32 models? Thank you. It is 1/35 scale, basically because I wanted to use a ready-made track kit from Tamiya. As the model is a big tank I would say the difference in scale compared to 1/32 is not really noticeable. Another picture of the front view of the real one is attached.

Cornish-model-farm Posted October 22, 2023 Author Share Posted October 22, 2023 More progress with the Sherman conversion. I have added the transmission and drive shaft, the batteries and the seats. These bits were from an obsolete Verlinden internal detail kit. 5 Quote Link to comment Share on other sites More sharing options...
