Thanks to the unique formula of our CoolTemp Hydro-Max™ Transmission Fluid, Grasshopper drive systems last longer and perform better than competitive systems. In fact, testing shows a visible difference in component life between systems lubricated with our Grasshopper fluid versus off-the-shelf hydraulic fluids. Specially formulated with patented anti-wear additives that maximize the service life of critical transmission components and minimize fluid and filter changes, CoolTemp Hydro-Max™ Transmission Fluid forms an advanced protective shield to eliminate break-in fluid changes and produce the lowest operating cost of all commercially available drive systems. Grasshopper recommends 1,000-hour change intervals with genuine Grasshopper fluid. That's up to four times longer operating hours with no maintenance. Grasshopper fluid costs less than 5 cents per hour to use, so even with large cooling reservoirs, it more than pays for itself in reduced oil volume and labor compared to other off-the-shelf fluids.
