Hayden, I know it seems like if you followed all of the manufacturer's safety rules/comments/suggestions that you couldn't get any useful work done B U T I have trained myself to always set the brakes before exiting the tractor. I do leave it running. If I need to jog the tractor forward or back while hitching an implement, I leave it in low range and can reach in and press the HST pedal foreward or back with my hand. Exercise care so you don't run over yourself! Even at idle, in low range, the engine/HST overpowers thte brakes and moves the tractor. If on level ground, you can leave the brakes off and jog the tractor a bit by grabbing the rear tire (tread gives hand grips) and rocking it a mite.
Since I always set the brake, the tractor isn't going to roll due to unballanced wheel weighting. Silly me, I asked the dealer if it would hop up and down at max speeds with non-symetrical weight installation (1 or 2 weights out of 3) but was reassured that it won't.
Until or unless there is a problem with rutting (let me clalrify that.. problem with making ruts), I will likely leave all the weights on as has been suggested. Looking forward to tractoring with 4 wheels on the ground.
Just the day before yesterday the nearest pond to the house was frozen over till late PM. I cruised over on the tractor and tested the ice with the FEL bucket to break it and note the thickness (early AM). It was about 3/16. As I tried to back away from the water's edge I just spun the rear wheels (nothing on 3PH). Switched to 4x4 mode, same result but spun a rear whees and ONE front wheel. Engaged diff lock and spun 3 wheels with no help.
After three tries I was able to use the FEL to raise the nose of the tractor and shift enough weight to the rear to back away from the water with a little assist from the curl control. For a while I thought I would have to go get my truck with winch to pull tractor away from pond. Even my "industrial" tires with less traction than Ags do pretty good with some weight on them.
