"Tracks will provide greater flotation (lower psi), stability and tractive effort than most conventional wheeled units," says Kuyers. "Tracks are most advantageous when the ground is muddy or when traction is poor for wheels. They will extend the amount of days that can be worked and without question increase productivity in most applications, which we have validated with our RTX quad track tractors. While tracks may cost more, they offset the increased price with this increased productivity. However, if the unit is going to be working in areas where traction is not an issue, then the wheeled units would be the most economical choice."
Tires are sufficient for most applications. "Today, by far, the most popular units are on rubber tires," says Bolay. "As a general rule, the rubber-tired units are cheaper to operate. They really do provide fairly good traction across a varying set of ground conditions."
Repair and replacement costs can also be a consideration. "A lot of times when you have a tire problem, it is one tire. Where on a track, it is a bigger dollar expenditure at the time to make a change," says Bolay.
