I have had a PP SR for 12 years. Was told I had to do nothing to the transmission. Now it is shot and the dealer tells me it is because I did not lubricate it. So much for maintenance free. $400+ to repair = new mower. My question is 2 neighbors love their Honda HRX - one with smart drive and one with hydro drive. What would you do in 24 hours - needing a mower - looking at mulching 100% of the time - and LOTS of hills. Thanks
