"Vari-Shift" transmission on B-112 offers seven power ranges within each gear selection . . . constant speed control through 21 forward speeds. Without clutching, shifting or throttle adjustment, you can vary power and speed through all working conditions with instant response.

**B-112 Only Completely new variable speed "Vari-Shift" selector gives the operator seven power ranges for each transmission gear.

SPEEDS: Choice of seven different variable speed ratios with high and low ratios as shown, with five other speeds in between in each gear.

VARIABLE RATIO HIGH POSITION 
1.7 mph in 1st gear 
4.0 mph in 2nd gear 
6.6 mph in 3rd gear 
3.40 mph in reverse

VARIABLE RATIO LOW POSITION 
0.8 mph in 1st gear 
2.0 mph in 2nd gear 
3.3 mph in 3rd gear 
1.7 mph in reverse

This is standard equipment on all B-112 tractors.  Unlike competitive units that have only one variable pulley, the new "VARI-SHIFT" utilizes two synchronized pulleys that provide constant speed control to the transmission. When one pulley opens, the other closes in the same ratio. This guarantees constant speed control through 21 forward speeds.

Without clutching, shifting or throttle adjustment, the operator varies his power requirements through all terrain and working situations, with instant response.  This does not effect power takeoff speed.

Eight gear selections to choose from on the optional "Hi-Lo" range transmission on the B-110~ You can vary speeds from 0.53 to 6.1 mph and still get full power at any throttle setting. The 3 standard forward and 1 reverse speed can all be reduced by approximately 50 percent with "Hi-Lo" for such work as rotary tilling, snow blowing, etc.

**Hi-Lo Transmission For B-110 Only
Optional transmission that provides 6 speeds forward, two reverse which reduces all standard speeds approximately one half and is recommended for operations such as roto-tilling, snow blowing, etc.

SPEEDS: 
(While operating engine at 3600 RPM) 
With 6-1/2" pulley 
1.6 mph in 1st 
3.7 mph in 2nd 
6.1 mph in 3rd
3.1 mph in reverse

With Hi-Low Speed Kit
.53 mph in 1st
1.23 mph in 2nd
2.03 mph in 3rd
1.03 mph in reverse

"Easy-Spin" starting uses a unique cam design to reduce required starting effort by 50 percent. The cam bleeds off compression at starting speeds but has no effect on the full rated power of the engine at running speeds. No moving parts, no adjustments -- ever.

Attach implements at any point from three power takeoff outlets -- front, center and rear. You need no extra engines no matter what the job -- snow removal, mowing or gardening.

**Power Takeoff - B-110 and B-112 
Both tractors have three power takeoff points, front center and rear. All may be operated independently or simultaneously with no loss of operating efficiency.

The front PTO is driven directly from the engine crankshaft Center and rear PTO are driven from the gear box forward of the final drive assembly. PTO speeds are not effected by varying ground speeds of the tractor.  The center PTO clutch is optional but shipped factory installed unless otherwise specified on dealer order.  The front and rear PTO clutches are standard equipment with front and rear PTO implements.
