  1. USMC Mustang: Great reply and I have a couple of questions if I may. Item #2: The reduced run time seems to be the most common complaint for the ZT480s. Have you done the Ryobi recommended battery test of load testing each battery individually? I was experiencing increased Battery Level Meter bars out on my RM480 in the first year of use. Ryobi had me individually charge each battery and then load test them (took them to a local battery shop for the test). One didn't past muster and was replaced. Mower ran (and still runs) better than new. Item#3: I'm extremely interested in
  2. The instrumentation on the Ryobi’s is known to be variably inaccurate. The ZT480s have been described by many as not reporting the charge % accurately. Some users have even had the meters replaced under warranty with no improvement. Based on my experience and from working with Ryobi support, the first thing I would do is fully charge the battery pack to when the charging lights on the charger and the mower glow steady green. Then measure the pack voltage at the bottom two contacts of the charging port. Voltage should be 51 - 52 volts. Then turn the key on and turn on the headlights. Now m
  3. I’ve been investigating replacement batteries for the RM480 & ZT480 mowers and have found some group 24 (75 Ahr.) and group 31 (100 Ahr.) SLA/AGM, deep cycle, 12 volt batteries. While these other batteries fit and might work in the Ryobi mowers, one rather large difference stands out. The Leoch LPC12-xxx batteries have a much longer lifespan. That is, installed in the Ryobi system, they will handle many more charge cycles than the the other brands. The LPC12-xxx batteries should give 1,500 to 1,700 charges. The Duracell Premium AGM batteries are rated at 850 charge cycles at the maxim
  4. Another picture of the new folding tailgate.
  5. Well, my RM480e just passed two years of ownership and the machine still runs like new. The electric experience has been wonderful. The mower costs less than $0.21 per hour to run. A seven month winter storage costs $0.91 for the entire period. Electric cost for the first two years has been $15.44 total. 87E10 has averaged $2.20 per gallon here. I have mowed for 59 hours in the two years and my neighbors 42” Toro Timecutter burns a gallon of gas per hour. You can do the math to see the cost savings the electric mower gives, not to mention there are no fluids, filters, or belts to mainta
  6. The instrumentation on the ZT480s (and the RM480s) has been reported by many to be inaccurate and misleading. The Battery Level Meter on my mower is erratic in its reporting and the hour meter is off by 6%. The hour meter even reset itself to zero last summer. I do some extra steps to monitor the battery performance so I know how healthy the pack is. 1. I measure the pack voltage before and after mowing. I use a volt meter to read the voltage at the charging port. 2. I bought a $30 recording watt meter to measure how much it takes to recharge the pack each time the charger does a c
  7. Hopefully you took pictures of the original wiring before you dismantled things. Don’t know if this helps.
  8. Paul: Sorry I haven’t replied earlier. I’m a bit wrapped up in supporting the HD Q&A web pages for the Ryobi riding mowers. Both the ZT480s & RM480s have questionable instrumentation. There are a multitude of questions on the HD web pages for the different models of the ZT about the instrumentation. My RM and my neighbor’s RM both have issues with the Battery Level Meter and the hour meter. The BLM is rather erratic and the hour meter is off by 6% on my mower. The ZTs have numerous instances of mis-reporting the charge percentage. People have eve had the meter replaced under warra
  9. Last month, Ryobi brought another battery electric riding mower. This one is a 30” 50 Ahr. model. $2,399.00 and on sale today for $1,999.00. Pretty much the same features as the bigger ones, except no cruise control, USB charging port, and phone slot.
  10. HD has them back in stock now with free shipping to your home.
  11. MarkTer: To properly test the batteries: 1. Pull them out of the mower. 2. Disconnect all wiring between the batteries and the mower. 3. Individually charge each battery with a separate automotive style charger, preferably one with a deep cycle setting. 4. Load test each battery. I took mine to a local battery shop for this. 5. Once the failing battery is identified, replace it. HD has them back in stock now with free shipping to your home. Sorry for the slow response, I sometimes forget to visit here.
  12. Sorry for the late reply, but the snow plow is back in stock at HD for $329 and free shipping. The manufacturer made a change to the plow lift handle to make it easier to raise/lower the blade without having to get up off of the seat and stopping the unit. Don't know about moving dirt, but it should work with loose dirt. I wouldn't use it like a bull dozer to break compacted ground.
  13. Rob L.: KayakerBob still has his and has it mounted for the second winter of plowing. He's working on making it easier to swing the angle of the blade from the seat. HD had an issue with listing the plow, but that has been fixed and it is available now
  14. You have to depress the brake pedal ALL the way down and while holding it down, pull up on the red handle on the side of the steering column. You should hear a click of engagement. In this doesn’t work, the brakes can be adjusted per the instructions in the maintenance section of the operation manual. Hope this helps. I just passed 50 mows and also love it.
  15. Just an update after one year of use. I mow 8,000 sq. ft. of lawn and occasionally a 16,000 sq. ft. lawn with my RM480e mower. Electricity cost to recharge the batteries is less than $0.10. I have mowed 40 times so far and the blades are still sharp. I did have one battery fail due to a failed cell that caused that battery to be unable to handle any load. Ryobi replaced the battery under warranty in two days. The batteries slide out on a tray. Maintenance on this machine is minimal and consists of lubricating the steering mechanism occasionally. The powder coated frame and deck are eas
