I posted the above a little over a year ago . The tow behind blower is in for maintenance . The battery area is as clean as it was when installed ( minus dirt and leaves ) . No battery acid spills , no leaky battery , battery connections are still the same as the day I put them on . There is no sign of corrosion anywhere . I'm going to repack the trailer wheels tomorrow . They have some play . The hubs look to be the same as the tru-turf roller . I may put some grease nipples in these as well . I'll post some pic's soon . It is well worth the expense . With all the electronics and wiring harness around the battery area it's a great idea .
