When i got my new 1 i was told to hammer it by the dealer, besides its under warrenty anyway. 
dont thrash it to the red line all the time but work it, & if you got an I-shift , drop it into manual on the hills & keep her in every gear as long as you possibly can, almost to stalling before you have to change down , i had 3 identicle FM12’s as they went , mine was KX57OGF & another wasKX57OGG they were much alike but KX57EBU was bordering on a glazed block , it would struggle to pull it’s self along empty , it had been the previous driver’s first ‘new’ truck & he’d mollycoddled it gently bently style & it was an awfull drive .
when i worked on farms the buying policy was to buy tractors at spring cultivations , so it would get some hard PTO graft on a powerharrow for a good couple of weeks that used to sort them out
