1. A ride-on floor machine, comprising:
a frame including a lower frame portion having a lower panel extending between a front end and a rear end;
a drive system carried by the frame; and
a blade control system carried by the lower frame portion, the blade control system including:
a blade holder pivotably attached proximate the front end of the lower frame portion;
a linear actuator coupled to the blade holder at a first end and coupled to the lower frame portion at a second end, wherein the actuator extends along a center line parallel to the lower frame portion and is operative to move between an extended position where the blade holder is in an up position and a retracted position where the blade holder is in a down position, wherein the actuator is a hydraulic cylinder having a cylinder rod; and
a shaft support bracket positioned to hold the cylinder rod parallel with respect to the lower panel.
 
6. A blade control system for use on a ride-on floor machine, comprising:
a frame portion attachable to the ride-on floor machine, wherein the frame portion includes a lower panel extending between a front end and a rear end;
a blade holder pivotably attached proximate the front end of the frame portion;
a linear actuator coupled to the blade holder at a first end and coupled to the frame portion at a second end, wherein the actuator extends along a center line parallel to the frame portion and is operative to move between an extended position where the blade holder is in an up position and a retracted position where the blade holder is in a down position, wherein the actuator is a hydraulic cylinder having a cylinder rod; and
a shaft support bracket positioned to hold the cylinder rod parallel with respect to the lower panel.
 
11. A ride-on floor machine, comprising:
a frame including a lower frame portion, wherein the lower frame portion includes a front end and a rear end with a lower panel extending therebetween;
a drive system carried by the frame; and
a blade control system carried by the lower frame portion, the blade control system including:
a blade holder pivotably attached proximate the front end of the lower frame portion;
a hydraulic cylinder coupled to the blade holder at a first end and coupled to the lower panel at a second end, wherein the cylinder includes a cylinder rod extending along a center line and is operative to move between an extended position where the blade holder is in an up position and a retracted position where the blade holder is in a down position; and
a shaft support bracket mounted to the lower panel and positioned to hold the cylinder rod parallel with respect to the lower panel.
