Hate to burst everybodys bubble, but to say that hydrostatic transmissions are not produced and used in tractors over 80hp is completely false. Many manufacturers like Fendt and others produce tractors with hydrostatic variable speed transmissions in sizes pushing 400hp with impressive fuel economy ratings. These tractors are designed for tillage work not putzing around 10 acres. Combines, Self Propelled Forage Harvesters, Bulldozers, Payloaders, Excavators and many more pieces of equipment all use hydrostatic transmissions or drives with very minimal problems that everyone likes to claim will happen. Do not be afraid of a tractor with a Hydrostatic transmission
