Can someone help me identify this mower? Hustler Excel 2500 w/ 25 hp Kohler (I believe - no visible markings) 60" deck Model: 924449 s/n: 002870 Deck Info is Model 924456 s/n: 004080 I just purchased this mower to cut down on my residential mowing time (have 4.5 acres to cut). Was advised by dealer that the unit was a trade in and used residentially only, System came w/ Bac-Vac and edger. I'm trying to find as much information as possible so that this unit will last. Any assistance would be appreciated.
