service design change. Elements such as upgrades in compo- nents and sealing procedures can provide for longer intervals between routine maintenance procedures such as greasing the PTO shafts.
A third example in redesign is easier access when routine maintenance is required. Relocation of grease fittings, so they are easier to get to, and thus more likely to be greased, is a good example. Pay attention to the grease specification that the manufacturer requires. An exotic, hard-to-find grease is going to cost more over the life of the mower than if the manufac- turer only requires a basic NLGI grade 2 grease.
Forward-thinking manufacturers seek ways to make the new standard features on their new mowing equipment available as a retrofit for their company’s older mowers. This ‘back-

Lastly, when you do need help, make sure the manufacturer has the infrastructure in place to support their product, including a network of experienced turf equipment dealers and the parts availability to keep downtime to a minimum.

Assumptions: • 8 hour working shift (excluding breaks) • *Reduction of maintenance by just 45 minutes (.75 hours) per day • Productivity based upon 6 MPH cutting speed —no overlap or turning Labor cost - $15.00/hour (not including cost of benefits / insurance etc.)
• Tractor operating costs have not been factored in
A small increase in operator efficiency or productivity may not sound like much at first, but how many extra pallets do you have to cut to make over $500 more net profit (not sales) per month? Choosing your mower wisely does pay.
