INTRODUCTION
Buhler Farm King has years of snowblower manufacturing expertise and thousands of
acreages, farms and cities depend on Buhler snowblowers.
PTO-driven Buhler Farm King Snowblowers attach to 3-point hitch.
This snowblower is supplied with category 2 pins with conversion bushings to category
3 available. 740 and 840 Snowblowers have open gearboxes. The Y840G has an oil
bath gearbox. Adjustable cup type skid shoes are standard on all models.
Three blade fans are on all models. A 4 blade fan is also available as an option.
Shear bolt protection is provided at the sprocket to the main auger, and is easily
accessed by removing wing nuts and cover at the back of the housing.
A hitch system, which is quick-hitch compatible is standard on all models. A longer 36"
PTO shaft is optional on the Y740 and Y840 models.
Also available is an optional Hydraulic Spout Control. There is a shear bolt on the
auger and on the PTO shaft to protect the machine from damage if a large object is
picked up. Any smaller objects in the snow will be thrown with it and could cause
serious injury. Do not allow anyone stand behind the tractor or in the area of the
discharged snow.
Keep this manual handy for frequent reference. All new operators or owners must
review the manual before using the equipment and at least annually thereafter. Contact
your Buhler Dealer if you need assistance, information, or additional copies of the
