KOHLER ENGINE USES EXTENDED LIFE OIL AND FILTER
Starting with S/N 21-168265, all Walker Mowers equipped with Kohler Engines are factory serviced with an extended-life PRO engine oil and PRO oil filter; the oil/oil filter change interval is increased to 300 hours. The new oil and oil filter are not required for future service but are recommended. Earlier tractors produced before this change can take advantage of the extended service interval by switching to Kohler PRO products at the next regular service. Order Kohler PRO Oil Change Kit, Kohler P/N 25 850 02-S. Note: If conventional oil and filters are used in the tractor, the oil must be changed after every 100 hours, and the filter must be changed after every 200 hours.
TRANSMISSION OIL PERFORMANCE SYSTEM (TOPS) ADDED
The new Transmission Oil Performance System (TOPS) has been added to all tractor models (MC, MT, MD) with Eaton Model 7 (M7) transmissions. TOPS consists of a reservoir, oil pump and oil filter which actively circulates and filters contami-nants out of the transmission oil. With TOPS, tests have shown the oil is kept significantly cleaner which improves per-formance, reduces wear, and extends transmission life. Additionally, an oil change has been added to the maintenance schedule, and if the TOPS system is serviced per the recommended schedule by an authorized Walker dealer, Walker will extend the transmission warranty to 3 years, full replacement coverage, unlimited hours.
LARGER DECK AVAILABLE FOR MR21
The DS54-R deck provides a step-up size for the MR21, facilitating wide-area mowing for the acreage owner. A belt-driven, three-blade design gives short deck-coupling, precision-quality cut, and good trimming capability. The Accelerator grass catcher mounts on this deck as an option. A mulch kit will be developed at a later date.
48-INCH SIDE DISCHARGE DECK INTRODUCED (DS48-3)
A new 48-inch, side discharge deck with belt-driven blades has been developed, fitting on Models B, C, D, S, T (tractors with PTO driveshaft). The design is based on the Model R deck geometry and is reinforced for commercial use. This deck features quiet operation, high quality cutting, and an optional Accelerator side-mounted grass catcher. The same mulch kit as used on the Model R 48” deck also fits this deck.
MODEL B FITTED WITH IMPLEMENT HITCH AND SOFT CAB
The new style Model B (B23/B27i) now has an implement hitch (H21) and mount kit for the (A17) soft cab. Also, a 50-lb tail weight kit and optional add-on weight plates are used to counterweight when lifting the front mounted implements.
EATON HYDROSTATIC TRANSMISSION OIL CHANGED
For models MS (before S/N 128441), MC, MT, MD equipped with Eaton Model 7 (M7) transmissions, the transmissions are now factory filled with Mobil SHC 630 high temperature formulated/rated oil, offering extended service life and improved transmission performance. Also, a 75-hour break-in and 500-hour oil change have been added to the maintenance schedule when using this oil. It is recommended to change to the new oil on all earlier units at the next scheduled service. See your Walker dealer for this service as instructed in Service Bulletin #21274.
