  1. 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.
  2. 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 easy to keep clean. The headlights are bright enough to actually mow at night and it’s quiet enough that you could without bothering the neighbor’s.
  3. Does anyone have any experience with the P750 pump. I’m thinking of using it to create a lawn sprayer to use on my RM480 electric riding lawn mower. The issue is that it pumps way too much volume and I would suspect that just using a valve to throttle the flow will cause damage to the unit. I’m thinking that splitting the output between the spray bar and a return to the tank will allow me to balance the output without stressing the motor. Just looking for feedback from anyone who has used the P750.
  4. Hi boys and girls. Ryobi just added a third and fourth all electric riding lawn mowers. This one is a 42" zero turn model. 75 Ahr. SLA/AGM batteries, but there is also a 100 Ahr model. Same as the 75 Ahr unit, but with bigger batteries like the other two riders. Large dollars, but the direction is there. This one is based on the same electronics as the prior two electric mowers, so it should be good performer. https://www.homedepot.com/p/RYOBI-42-in-75-Ah-Battery-Electric-Zero-Turn-Riding-Mower-RY48ZTR75/308040422
  5. kayakerbob plowed my drive and all of the sidewalks on the street today with his RM480ex and the new front mounted plow from HD. Did a pretty good job and you didn’t hear him at all. Good way to condition those new batteries,
  6. Here's the most comprehensive article I've found on battery care for electric riding mowers. Wish the manufacturer had put something like this in the owner's manual. https://mycountryacre.com/5-ultimate-electric-riding-mower-battery-care-tips
  7. Just wash them with bleach to get all of the pond scum off. Sorry, couldn’t resist. To finish SLA/AGM batteries, don’t discharge them more than 30% for the first 10 - 20 uses. As they become conditioned, you will see fewer battery level bars turn off for a give time of usage until the usage stabilizes. When I first started using my RM 480, 2 bars would turn off after about an hour of mowing. Two bars is less than 30% of the total charge (each bar is 10%). After a few mowings, only one bar would turn off. Later, no bars would go out after mowing for nearly an hour. It stabilized at that point and I considered that the batteries had been properly conditioned. Take a look at the RM480 article at MyCountryAcre.com and visit BatteryUniversity.com for more information on SLA/AGM batteries. Unfortunately, Ryobi doesn’t say anything about this in the Operator’s Manual and I’ve seen a few users complain about premature battery failure or shortened capacity life. Don’f Forget to show us your snow blade when you get it.
  8. The neighbor two doors down took delivery of his RM480ex (100 Ahr model) today. He also bought the newly announced 42" front mounted snow blade for it, but that won't be delivered for a few days yet.
  9. Sorry, but I just discovered that I mis-spoke about the Husqi mower. It,s a 36 volt 125 Ah pack and has a run time of 90 minutes. Price is $4,000. Still a bunch more than the RM480s. It also has a smaller deck width than the RM480.
  10. Yeah, the Husqi does tow it's battery pack behind it in an articulated design. It's a 12 volt 100 Ah pack. Here's where the Ryobi design comes up as an advantage. The Husqi runs for an hour and costs about $5,000 US while the Ryobi design runs for 2 (or 2.5) hours on a charge and costs nearly half as much. Actually the RM480 is the only electric rider on the market that sells for under $5,000 and runs for two or more hours. The ones that do run longer are the Mean Green mowers and those have price tags way up there.
  11. I know this is an old topic, but I bought one of these mowers in August and it is well worth the price. I had to drive 45 miles to the nearest HD that had one on the floor to see what it was all about, but compared to the other small riders, it was worth the drive. The design and engineering is stout and it cuts as well as the 21" Honda walk behind it replaced. Compared to my neighbor's $3,400 42" Toro Timecutter, it was a steal. After I had properly conditioned the batteries, I can mow for almost an hour and use less than 10% of the charge. It costs me less than $0.06 worth of electricity to recharge the pack. The pack consists of four 12 volt 75 Ah Sealed Lead Acid/Absorbent Glass Mat batteries in series and they should last between 5 and 10 years depending on usage. The gas/oil/filters/belts/and engine maintenance savings will pay for a total battery replacement in about 4 years. Oh yeah, it's really quiet. They just brought out a front mounted snow plow attachment for this mower. I made the tail gate to haul a trash can for yard work.
  12. Good Catch! Thanks JC! The operative word here is RTFM (Read The Freaking Manual). I gagged this problem on two fronts. 1. I had forgotten about the "Oil Alert" feature of the engine as detailed in the Honda manual that came with the unit. 2. I also was checking the oil level incorrectly. I was reading the dipstick with the plug screwed all the way in. The manual clearly states to check the oil level by butting the plug up to the opening. I always check the oil level in all of my gas powered tools prior to using them, but I was always getting a reading that was falsely too high on this one. I filled the crankcase to the proper level and the unit runs as it should.
  13. I have a two year old DP3100 that suddenly quits running under load. It worked fine last week when I cleaned a 20' x 40' pool cover. I have it connected to a city water supply with a 5/8" hose at at least 40 psi. It will run fine for a few minutes or less and then the engine shuts down. It starts normally, but quits running after it warms up. Any ideas? Thanks.
