Mowing Season 2019 build

I'v seen StandUp mowers used, but Have not had a chance to try them.
So this season I'll build one.

Hybrid Stand Up mower.

the 48" mower deck with 17hp briggs, the wheel drives are going to be DC servo motors.
the briggs engine will also power a generator to charge the DC batteries for the wheel drives.

total run time of the wheel drives without the generator running is going to be 30min.
(about 60Ah which 2 standard car batteries)

I'm still scratching my head as to the type of control setup.

Thinking one handed operations, or maybe no handed(food for thought).
Thinking wireless operations(able to go under brush, low branches, with me not on it.)

my current controller is not up to the job, needs 2 hands.

Thinking to start, Ill try some type of harness holding the controller.

the Servo motors found on ebay for 400.00 for a set(one right, one left)
the motor speed controller from Amazon was 200.00, the motion controller
from Dimension Engineering was 25.00, batteries(2) from walmart
140.00.



was hoping to keep build budget at $1500.00 with using stuff I have or can find.

This is the deck I'm going to make Stand Up.
the deck could use a cleaning and blades a little filing.

I noticed that the platform I stand on is going to need to be hinged
so I can still lift the front end of the deck to service the blades.

last season I had the servo motors mounted very low
on the mower deck, but if I then traveled through
an area that I already mowed the low sprockets started
to look like Chia Pets, so this season I'm installing the
servo motor up higher.

Need another little motor down there that spins a bush on the chain to keep it clean.

Mark, your idea is looking like a better option then mine.
the motor is not centered on the mowing deck, got .5" of
clearance between the mowers motor and the drive servo
motor on one side, but hit on the other side.

there are 4 - 9/16th bolts holding the mowers motor to the deck
if I used 5/16-18 bolts it should let me center the mowers motor
better.

Sweet!
just replacing the gas engine's 9/16 mounting bolts with 5/16
gave me the clearance needed to mount the servo motors to a
higher location.

plan B was very bad, mounting the servo motors in front of the gas engine
and over the mowing deck. this was bad because the servo motor would be
in the area of the gas engine's exhaust.

my hope is that having the servo motors up high would
also take them out of harms way.

the image below is of servo motors after just one season
under the mowing deck.

the motors in much better condition I found on ebay last winter.

plan A for on-board control is a steering wheel setup.
that would allow single handed steering, the speed
is controlled by a thumb slider mounted on each side
of the steering wheel.

the green things are rotary angle sensors that connect the
steering wheel and speed sliders to the mowers electronic
system.

the on-board control setup should cost about $300 to make with
the stuff I can find, like bearings,belts and pulleys, and steel/Aluminium stock.
