I am very sorry for your loss.
As a new tractor owner I often check the periodic postings here. I almost always proceede in lowrange with a load in the FEL or behind. When the ROPS is up I try to never forget the safteybelt and do not wear it when the ROPS is folded down. One issue I have with the brakes is they do not hold on hills when I dismount. The adjustment seems to be in the right amount of range and freeplay, but I still hate having to leave the hydro in gear with it running, even with the brake applied, I know it does not help much, but its deffinately better than leaving it in neutral. Most times I try to chalk the tractor with an outrigger or the bucket blade. Any other ideas would be a great benifit, the model is a BX23.
