Like anything the life expectancy of a piece of equipment is determined by how well it is taken care of and how it was used. Below is a list of the main wear components of Exmark mowers
and how long you can expect to see them go. Most of these hours are only reached by commercial cutters. As a general rule the average homeowner will only put 50 hours a year on a mower.
Exmark has used a number of engines in the past which include Briggs and Stratton, Kohler and Kawasaki. The most common engines are Kawasaki and Kohler. The average life expectancy of one of these commercial grade engines is usually 3,500 hours with oil change intervals of 50 hours. Typically at 2,800 you can start to notice a lack in power, usually do to low compression. We have seen engines last as long as 5,500 hours and even have had customers put 7,000 hrs on units, this is by no means ordinary and oil changes we done on a weekly basis.
Exmark uses a hydraulic pump
to wheel motor
drive design. Prior to 2009 these systems would last on average 1,000 hours. This design has changed drastically in 2009 when they combined these two units into one, eliminating hydraulic lines. These components have meeting their life expectancy of 1,500 - 2,000 hours.
Exmark mower decks are among the most rugged in the industry and their patented design makes them the most sought after for commercial cutters. The mower deck shells themselves really never wear out, but the mower spindles
do need replaced near 500 hours of use.
Common Replacement Parts:
Every mower has common replacement parts, on Exmark's there are maybe a few less than other manufacturers which make them great options for commercial use. Typically when steering seems less responsive simply replacing steering dampers
can make it feel like to new again. In commercial application replacing caster wheel parts
maybe necessary due to regular loading, unloading, and constant abuse. Of course you will need maintenance parts like belts
and filters as well.
