Parts category
Batteries
Kubota batteries use the most current technology to make sure there are sufficient and powerful as possible. These normally include a negative plate paste expander, and a sodium sulphate additive.
Belts
Kubota zero turn mower belts are claimed to last up to 3 times longer than comparable aftermarket products.
In addition, they are made in what is called an alignment line, allowing the courts to equalise the energy distribution flow. This results in a more stable tension. In addition, they contain fiber enforced rubber that helps support the integrity of the belt
