Buhler YT450 Lawn Mower User Manual


 
The best mower for the best cut
Buhler Farm King has been making nishing mowers for more than 15 years. ree
of these nishing mowers together create one magnicent volume grass trimmer: the
Triplex Finishing Mower. Nine blades generate a powerful vacuum for a crisp, clean cut.
Each deck oats independently over rolling terrain for a uniform, manicured trim. ere
is a 1 ⅝" blade overlap on the YT450, while all the other models have a 2 ⅝" blade over-
lap. is overlap helps to prevent stripping, especially when turning. e standard front
UHMW roller prevents scalping on uneven turf. A 5-position hitch adjusts to most
tractors allowing the mower to remain level, achieving an even cutting height.
Transporting with ease
Whether moving from the third fairway to the tenth, or from one side of the city
to the other, the Triplex Finishing Mower is designed to be transported with ease. A
cast clevis hitch is standard and a 2 ⁄" ball hitch is optional for road transport. e 5-
position hitch adjustment makes it easy to move, regardless of the hitch height of the
tow vehicle. e decks are lied into position by hydraulic cylinders and are auto-
matically locked in place for transport. Upon arrival at the destination, the decks are
unlocked right from the tractor seat using a cable, or can be released using the optional
hydraulic system. Either way, it makes moving to a new location easy.
