Abstract
Abstract A foot pedal is connected to a first link which is also connected to the first arm of a bellcrank. The bellcrank is secured to an input shaft of a hydrostatic transmission. The first link is adapted to reciprocate in opposite directions upon pivoting of the foot pedal in opposite directions. A second link, interconnected between a second arm of the bellcrank and an engine throttle control lever, is adapted to pivot the throttle control lever in the same direction in response to reciprocation of the first link in either direction thereof. Thus, depression of the pedal in either direction will actuate the transmission to place it in its forward or reverse mode of operation whereas the throttle control lever will be actuated in the same direction in response thereto.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
147 words
A transmission and throttle control arrangement comprising transmission control means having a rotary input shaft, a bellcrank secured to said input shaft and having first and second arms throttle control means, actuating means movably mounted on a support for movement between first and second positions, a first link means interconnected between said actuating means and the first arm of said bellcrank and reciprocal in a first direction upon movement of said actuating means to its first position and reciprocal in a second direction opposite to said first direction upon movement of said actuating means to its second position, and a second link means interconnected between the second arm of said bellcrank and said throttle control means for movement in the same direction to actuate said throttle control means in only one direction in response to actuation of said actuating means to both its first and second positions.
Claim 2
Dependent Claim
147 words
A transmission and throttle control arrangement comprising transmission control means having a rotary input shaft, a bellcrank secured to said input shaft and having first and second arms throttle control means, actuating means movably mounted on a support for movement between first and second positions, a first link means interconnected between said actuating means and the first arm of said bellcrank and reciprocal in a first direction upon movement of said actuating means to its first position and reciprocal in a second direction opposite to said first direction upon movement of said actuating means to its second position, and a second link means interconnected between the second arm of said bellcrank and said throttle control means for movement in the same direction to actuate said throttle control means in only one direction in response to actuation of said actuating means to both its first and second positions.
