The editor of Bibbesworth's Tretiz interprets the form in tres- as a variant spelling for trestel (AND ) in Bibb Roth (T) 271 and (G) 560, meaning a stack of grain 'constructed like a trestle' (see Bibb Roth p.34 n.7 and p.79 n.18). However, the semantic link to trestel meaning 'a support for boards or planks serving as a tabletop' is unclear, and there is no further evidence of this word ever being used with reference to a stook of grain.

The variant reading of trussel in manuscripts B, Y and C suggests that this word could be interpreted as a deviant (with vowel shift) of this entry. Other tres- forms for trussel can be found outside the Tretiz tradition (see the London Mun Coll example). The word trussel (as does trusse) is used in an agricultural context for a 'truss, a bale of hay' (see trusse1), which sense, in the Bibbesworth text tradition, seems to have become extended to 'sheafs of grain stacked together', as suggested by the Middle English glosses stack, shok, stok and knicche (see MED stak n., shok n., stok n.1, knicche n.).
