Why not cut with chains? Agricultural tires work well on grass, but they don't work well without chains on snow. It looks like you want to save a dollar. The disadvantage of running on a chain all year round is that driving quality will suffer. In addition to checking inflation pressure, get in the habit of performing a regular visual inspection of your tires.
The arrival of winter weather presents a series of new challenges for small-scale owners and amateur farmers who are serious about getting the most out of their compact tractors. R-4 tires are found on many compact tractors because they offer a good balance between hard and soft service performance, however, they are not the best choice for snow removal. Evaluating your tractor tires before the season is a critical step in achieving a successful winter, but so is maintaining them throughout the season. Another option for compact tractor owners, whether they need new tires or not, is to switch to a more suitable tire for snow removal.
I will say that current winter tires, such as the Bridgestone Blizzak or the Firestone WinterForce, really improve traction, especially the Blizzaks, even on ice with their very soft rubber on the tread. You don't want to wait for that big snowstorm to arrive to discover that your tractor doesn't have enough traction to dig, push, or pull you out of the snow. If you're coming to the end of the tread on your tires or have tires with a skewed construction or with an incorrect design, now is the time to invest in new ones. Tires are what connect a tractor to the ground and play a fundamental role in the way the tractor is hooked up.
Most compact tractors are equipped with R-4 (industrial) tires, which feature traditional tread patterns with bar-like lugs. Because inflation plays such an important role in the performance, lifespan and total cost of ownership of a tire, it's critical to operate it with the correct pressure for the weight applied to the tractor and the speed at which it will travel. Before the scales start flying, make sure the machine's tires have sufficient tread to provide adequate traction in winter conditions, such as snow, sleet, and ice. My friend, who has experience with everything related to tractors, told me that he expected agricultural tires to be useless in any layer of hard snow or ice.
