GET a heavy duty boxblade, about 900lbs for the
L4610. Besides being extra durable, you can't beat it for manuverability, strength and superior ballsat. Mine weighs 1200lbs. With that much weight, 40" or so to the rear of the wheels, it offers some great ballast for a fully loaded bucket even on inclines.
RULE 1. CARRY YOUR LOAD LOW!!! IF YOUR HUSBAND HAD BEEN, IT WOULD TIP FORWARD (NOT ROLL) ONLY UNTIL THE BUCKET TOUCHED THE GROUND.
RULE 2. WHEN YOUR DRIVING YOUR TRACTOR WITH A LOAD IN THE FRONT BUCKET, INCLINE OR NOT, HAVE YOUR RIGHT HAND ON THE LOADER CONTROL AND BE READY TO PUSH THE STICK FORWARD AND DROP THE BUCKET, WITH A LOAD IT WILL DROP RIGHT NOW. DOING SO WILL PLACE THE CENTER OF GRAVITY BACK AND PUT THE REAR END ON THE GROUND. I have done it so many times its second nature to me, practice it, panic will may you do strange things.
I'm also suprised the dealer didn't get all this information to you when you bought the tractor. If you are ever working without an implement on the back, not only had you better have ballasted tires, but even then be very careful, hand ready at the loader control ready to drop the bucket. Don't fill the bucket up full either, especially if on a incline. RaT...
