The answer is Yes.. I have done some research on this because I ,myself a heavy user of Tractors here in Canada ( own two ). My latest data on this is as much as 80% of Ag machinery (including Tractors,Harvesters, combine etc) and good amount of construction equipment including Excavators are built/assembled in Iran..HEPCO is the biggest construction machinery manufactures and Tabriz has one of the biggest Tractor manufacturing plants in West Asia (including Engine). I have already covered the construction part in the "Made in Iran" thread here.
75 ton Excavator by Iran's HEPCO
Note 75 ton excavator is considered to be in the top heavy class excavators..
The original tweet says designed and built in Iran with 35% parts made in Iran which is good but we can do much more..
