Hey guys,
Running into several math problems, with the biggest being financially oriented.
I have a 20 year old Toro Zero Turn mower whose HydroStatic unit finally went out ($700 to replace) and the 24hp ICE has been giving me minor issues as well, so what better time to look into my first Electric Conversion. Also note the hydrostatic drives on this mower have been the biggest service problem since day 1, so I'm not excited about replacing the unit if possible. If I replace the hydrostatic unit, then I'll just probably sell the mower and go to another ICE.
I've been reading the threads contemplating my engineering and was originally going to convert the ICE with a dual shaft PMDC to drive the blade deck and the hydrostats. Now that the hydrostat went out, I'm back to trying to figure out a more cost effective means to motorize. Current design right now I'm looking at Montenergy ME0909 4hp PMDC for the 2 drives ($365 x 2 = $730) (feels like overkill), dual motor controller ($200-$400 depending on brand), and I'm looking for some single axis joysticks to replace the handles ($??). Then use a Montenergy ME1004 10.5hp PMDC with no controller ($525) just a switch relay ($10-$15)for the blade deck. Problem is that I'm over $1600 and I haven't bought batteries. Haven't found any used motor providers around here that fit my voltage or size needs.
Some of the threads have suggested using 12-24v winch motors for some applications. Can I use a 24v motor for the hydrostatic drive replacement? 1-2hp should be fine, but not sure about 1hr continuous duty on this type of motor. Also not sure about the wiring of all the solenoids and using a single axis joystick as the forward/reverse switch for each motor. Lot of solenoids.
I'm reading and reading, but sure would appreciate some experienced direction from real experts...
