Question

what age does draft horses get fully grown

Answer 1

Most dont fully mature untill about 8 yrs old... which is alot older then most breedes... but because the grow to be so heavy it takes alot of time for them not only to grow up but also bulk out... most start getting broken in around 6... but shouldnt be in full work untill at the earliest 7... in saying this the cross breeds and some drafts mature a bit earlier...

Answer 2

I'm not 100% sure but i've heard  it's around 5 yo or so.
