TOPS™ brings enhanced drivetrain protection and performance to Walker Mowers equipped with Eaton Model 7 hydrostatic transmissions by actively circulating and filtering the transmission system fluid every 38 seconds.

|Active filtration reduces contamination and wear to transmission components|
|Doubles hydrostatic drive system oil capacity for increased oil life|
|Superior protection in high duty cycle applications and high ambient temperatures|
|Improved system cooling|
|500 hour oil change interval|
|Extends your Eaton hydrostatic transmission warranty with Walker|
Eaton hydrostatic transmissions are by default covered by a 3 year/3000 hour warranty to the original owner.
Walker will extend the transmission warranty to 3 years, unlimited hours if the transmissions are serviced by an authorized Walker Dealer at the recommended intervals using only Walker recommended oil and filters. Conditions apply, see your Walker Dealer for details.
The TOPS™ filter and the oil must be changed after the first 100 hours, at 500 hours, and every 500 hours thereafter. Eaton hydrostatic transmissions ship from the factory with TOPS™ Mobil SHC™ 630 oil. TOPS™ Mobil SHC™ 630 is the only factory approved transmission fluid for servicing the transmissions in this tractor due to its improved performance.

The hydrostatic fluid level should be checked after every 25 hours of machine operation. Always perform this check when the machine is cold.
NOTE: If you regularly are running a bit low, it is likely there is a leak. Contact your authorized Walker Dealer for inspection and repair.
