700 Series Lawn Tractor Assembly

Torque specifications may be noted in the part of the text that covers assembly, they may also be summarized in tables along with special instructions regarding locking or lubrication. Whichever method is more appropriate will be used. In many cases, both will be used so that the manual is handy as a quick-reference guide as well as a step-bystep procedure guide that does not require the user to hunt for information.

The level of assembly instructions provided will be determined by the complexity and of reassembly, and by the potential for unsafe conditions to arise from mistakes made in assembly.

Some instructions may refer to other parts of the manual for subsidiary procedures. This avoids repeating the same procedure two or three times in the manual.

Description of the 700 series

1. Description: A new step-through rider platform was introduced for the ‘05 mowing season. It was designated as the 700 series rider. It is seen across many of the MTD brands and private labels. There are also several hood configurations.The serial number and date codes are the keys to obtaining proper parts and service information. Since that date, several drive systems have been used on this series.

2. Variations: Drive Systems The 700 series is currently available with three basic drive systems. The 700 refers to the 5th through 7th characters of the model number found under the seat.

• 13AN772G000 is a “770” series - 7 speed shift-on-the-go transmission

NOTE: There is also a 760 series with a 6 speed shift-on-the-go transmission

• 13WX78KS011 is a “780” series - autodrive variable speed CVT tractor

• 13AR791G790 is a “790” series - Hydrostatic drive tractor

The 760-770 series is a shift-on-the-go system that uses a simple forward/neutral/reverse transaxle driven by two belts in a variable speed pulley. A dash mounted speed range control (sets speed of rider). A foot operated brake on the left side of the rider engages the drive when it is released.

The 780 series uses a Autodrive system with the same transmission as the 770 series. The 780, like the 770, has the brake pedal on the left side of the tractor. A drive pedal on the right side of the tractor controls a variable-speed pulley (CVT) system that controls the ground speed of the tractor.

The 790 series uses a hydrostatic transaxle. A pedal on the left side of the tractor operates the brake/clutch pedal while the ground speed and direction of the tractor is controlled by a fender mounted hand control lever.
