Expensive BUT effective.
This product is almost double the price of your run of the mill transmission fluid but for our zero turn mower and compact tractor it's the best we've tried. Very efficient.

Major improvement in operation.
Well worth the cost. I have a Cub Cadet commercial zero turn and the Hydrogear drive units have been noisy since new. I have changed the fluid and filters several times and used different brands of fluid. This TRIAX fluid is amazing, I changed to it yesterday morning and then mowed my 1 acre yard and the difference in noise level and smoothness was just astounding. I am sold on it forever now. My son is going to order some for both of his ZT's because he is having the same issues with noise and sluggish operation after getting hot. I will be looking into other products made by TRIAX as well.

sehr gutes Hydrauliköl, Automatikgetriebe Husqvarna Aufsitzmäher läuft hervorragend
Automatikgetriebeöle sollten hochwertig sein und hier sollte man nicht mit jedem Cent sparen, ein neues Getriebe durch Anwendung von Billigöl ist dann viel teurer und vor allem gibt es solche neuen Getriebe 10 Jahre nach Kauf des Gerätes praktisch nicht mehr. Dann kann man z.B. einen Husqvarna-Aufsitzmäher für einstmaligen Neupreis von 11.000 EUR (!) in den Schrott werfen! Dieses Öl kann ich vorbehaltlos empfehlen.
