There are 2 types of wheel motors for Exmark mowers. Large frame and small frame. My suggestion is to make sure you get the wheel motor numbers off of the old motor and compare it to the motor from McHenry Power Equipment. Then call them to make sure they wrote down the correct number you gave them. Ask if they will reimburse you for shipping if they wrote down the wrong number. If you ever need another wheel motor, may I suggest my former company
Welcome to Marathon Hydraulic Motors. They are national repair house with an exchange program for wheel motors for all types of lawn care equipment. Very reasonable! A re-built wheel motor with a same as new warranty 1 year is $325. Better than $600+ from other companies. And Shipping is FREE. Good Luck, Mike Johnson
