Thats what I thought too, with all that weight it should be more stable. That however is not the case. That bucket is huge and holds a ton of dirt, rocks etc. I can literally bring the rear wheels off the ground picking up a full load or wet clay type dirt or shale rock even with a box blade on the back. I need the weight of my 1500 bushhog but then it is too long and gangly to maneuver. One day, wife wanted some dirt put into her flower bed which is on a slight slope, not much just maybe 5 degrees. I loaded up a load and keeping it low to the ground I moved it from the pile to the bed. Moving slow, I was approaching the dump point and the uphill tire hit a small clump of dirt about the size of a coffee can and it was enough to tip the tractor up on the front tire. Luckily I was really close to the ground with the load and I always keep one hand on the joystick. I dumped it to the ground and let the tractor settle back, then raised it and went ahead and dumped it. I am really mindful now of side loading and even slight inclines. This spring, I am for sure going to load my tires. $40-50 bucks per tire for antifreeze is not going to break the bank. I northern Louisiana where my Dad farmed, he used just straight water. The sometimes froze solid, but he didnt use them in the winter anyway. He said as long as the tire wasnt sweating on the outside when it warmed up after a freeze, it was oK to run. Those black tires setting in the sun thawed pretty quickly. I have pure water in my Yanmar tires and I dont think they have ever frozen but then I dont use it when it is below about 40F because it wont crank anyway without blowing hot air into the air breather. It doesnt have glow plugs.
