yes teh new powerstar series will replace all teh T4000, TD5000, and one of the T5000 series tractors. they will be a T4.75, (75hp), T4.90 (90hp) and T4.100 (100hp). they will have a power shuttle shift, an all new interior and cab, they are the only tractor on the market to offer a full size buddy seat in the cab. the tractor look liek a smaller version of the T6000 series. There really arent any good brochures out yet. THe T4.75 is due to start shipping out in April and the other two model not until the fall of this year. price wise the T4.75, 4x4 with cab and loader will be right around $40,000 give or take a little. if you want to know more just ask. thanks
