IGT Technology
The Tuff Torq IHT (integrated hydrostatic transaxle) system is truly unique in its design and performance. Our IHT units use the patented Tuff Torq L.O.G.I.C. case system. L.O.G.I.C. stands for Lateral Opening Gear Isolation Case, and it sets our transaxles apart as some of the most dependable and smoothest hydrostatic drive systems available on the market.
First, the “Lateral Opening” case is separated horizontally into two main case sections. This makes servicing our units much easier for dealers and service departments, since the transaxle can be laid in a stand and serviced more easily and with less clean-up afterwards.
Our “Gear Isolation” design means the hydrostatic drive pump and motor chamber is completely separated from the gear drive chamber. The oil, which is used to drive the hydrostatic operation, must pass through a filtration system as it passes from the gear chamber to the hydrostatic chamber. This helps remove any material or debris that has been picked up on the gears before they can damage the precision components of the pump and motor. This gives our units longer life and better overall performance.
