To complete the series, after the first and second iterations, also built the third and final version of a Meccano model of a hay tedder.
Here shown again as "Hooi Keer Machine" in a 1937 Dutch book of instructions.
Numbered model E8, this is a model needing at least an Outfit E.
Meccano had changed their system of tiered Outfits in 1934 from numbered sets to lettered sets with new parts (plates) and bright new colours. The new range started with a small Outfit A, all the way up to the massive Outfit L. There was an even smaller Outfit 0, that was outside of the lettered system without upgrade set to make it an A. This lettered system was replaced in 1937 with a new range of numbered sets. This lettered-system booklet from 1937 is from the last year of these sets, and also the last year a model of a hay tedder was in the manuals.
The model is quite brilliant in the blue and gold. (A bit bright for a working farm implement perhaps :)
The model is essentially the 1928 version, but with plates added to close the sides of gthe 'box' around the single rotating rake. Pulling in the sides to the 3-hole width of the sector plate does put a lot of stress on the parts - strips get bent quite a bit.
Both the driving axle and the tedder-rod now use a 1" pulley, so this version also does not really 'ted'. The rake ends actually move slightly slower than the hay-tedder itself moves over the ground.
When the entire system was again reorganized into numbered sets, the hay tedder did not return. By 1937 a hay tedder was perhaps no longer a marvel of mechanical achievement to be modelled.
