I know that there is a gearing difference between 200 and 400 series motors due to tire height. But they are inter-changable. (400 series motor will fit in 200 series transaxle and vice versa) But is there a difference in the 600 series motors? Are they inter-changable with 200 and 400 series? Also are 400 series and 4xxx series motors inter-changable as well??

Thanks,
Bob

Hi, Bob
The gearsets in 200 and 400 series transaxles are the same. The "gearing" difference lies in the drive motor itself. The 400 series uses a larger-displacement motor which turns more slowly but with more torque. This makes up for the increased tire height. 400 and 600 series drive motors are interchangable, and while I'm not sure if a 4000 series motor will interchange, I can't think of any reason it wouldn't.

I recall Tom Hanson mentioning that the 600 series drive motors differ from the 400 series motors though they should physically interchange. Among the 600/6000 and 7000 models there are at least 3 different tire/wheel sizes so I can imagine there might more than one motor.

I think............. that Tom Hanson was referring to the motors used in the 6000 being of a higher torque rating.

I did some research on this recently when the whole Torq issue came to the forefront and I can tell you that all three 600 models use the exact same motor and it is the same part number as the motor used in every 400 model, except for the early 442.. That model used a motor that was similar to the motors used on the old 100 series. Tom is a member here but I don't know if he's found a moment to look in on us.

I installed a 222 orbital motor in my T-444. It really made the tractor run!!! It lost a good bit of power in high range though. I can actually kill the engine at anything below 3/4 throttle by moving the drive lever to fast... The motor in my 4016 looks to be the same as the motor in my 444 so I would say those motors are identical..
