Little inexpensive fresh look update on the mower with aluminum intake and exhaust dust covers:

2850595001 - Left side
2850594001 - Right side

Your thoughts?

First of all, let me state that I do like the reviewer of this channel and he has made many good review videos.

On this released "information video" (https://youtu.be/oFf2sWA7nPE?si=82eEIqrt4UpBzLB- I), believe there are some incorrect information that might be collected from incorrect sources and could mislead some buyers considering the cost of this 30" mowers.

1. Torque number on the 30" models are presented wrong:

Unless both blades operated by the independent 6.6ft-lb torque or 8.1ft-lb torque dual motors from either the commercial or the residential 30" mowers are able to strip at all the same grass blades at the same time, combining both torque numbers together is not physically or scientifically correctly presented.

On the EGO 30" mowers, it is IMPOSSIBLE because they do not have "Timed/Clocked" overlapping blades design but having a small gap between the two blades (why the previous testing of this channel show the middle of the 30" mower path did not get cut cleanly)

2. RPM speed in different modes are not correct:

30" 1300Series/LM3004SP-2-PC/PBT
- Small Motor Housings/Higher Intake Volume
- Brushless /per - 6.6 ft-lb @2,500rpm/motor
- Side-by-side twin blades w/ high Airflow
- 15.177" Single Wide-Mulging Blade-Longer Clippings
Mode 1: 2,800rpm/11,126SFM/126MPH
Mode 2: 3,200rpm/12,715SFM/145MPH
Turbo: 3,600rpm/14,304SFM/163MPH
S-Turbo: 3,700rpm/14,701SFM/167MPH
Max: 3,800rpm/15,099SFM/172MPH
exceeds 200cc gas-powered mowers

30" Commercial LMX7600SP-PC/PBT:
- Small Motor Housings/Higher Intake Volume
- 1000W Brushless/per - 8.1ft-lb @ 2,500rpm
Side-by-side twin blades w/ high Airflow
- 15.177" Single Wide-Mulging Blade-Longer Clippings
Mode 1: 3,000rpm/11,920SFM/136MPH
Mode 2: 3,400rpm/13,509SFM/154MPH
Turbo: 3,800rpm/15,099SFM/172MPH
S-Turbo: 3,900rpm/15,496SFM/176MPH
Max: 4,000rpm/15,893SFM/181MPH
equivalent of a 230cc gas engine

3. LMX5300SP 14.8ft-lb torque is measured not based on the industry standard of 2,500rpm like all other EGO mower but at 1,750rpm. @ 2,500rpm the tested technical specification is 12.8ft-lb torque.

22" Commercial LMX5300SP-Aluminum:
- Small Motor Housing-High Intake & Airflow
- 800X heat dissipation vs Polymer/PC-PBT
- Brushless 1600W - 12.8ft-lb @ 2,500 rpm
- Advertised 14.8 ft-lb @ 1,750 rpm ~230cc
- 21" High-Lift Single Blade/larger clippings
- 4 Blade rpm Modes & Blade-Tip-Speed:
Mode 1: 2,700rpm/14,689SFM/167MPH
Mode 2: 2,850rpm/15,505SFM/176MPH
Turbo: 3,000rpm/16,321SFM/186MPH
S-Turbo: 3,100rpm/16,865SFM/192MPH
Max: 3,350rpm/18,225SFM/207MPH

EGO's Super-Turbo rpm is NEVER the Maximum rpm speed.

Unlike the misleading 13.2 ft-lb torque listed on the residential EGO Peak-Power LM3004SP-2 by combining two 6.6 ft-lb torque per motor numbers together to sell more at weaker performance, the commercial LM7600SP is clearly stated on the commercial website of 8.1 ft-lb torque per motor.

Since each blade is not cut by both blades at the same time, combining the torque numbers for two independent motors is simply misleading to the consumers to make them "feels good" of having a more powerful machine and "believing" it will do a better job than any of the EGO 21" or 22" mowers with dual stacked blades. It is not so at all as both 30" models has less Blade-Tip Speed than the 22" models. They finish the job faster, NOT better!

With the introduction of 22" LMX5300SP, 1100 & 1000 Series mowers also comes with some less know features that can maximizing the performance of these mowers.

These 22" models currently are the only models that have intake and exhaust ventilation panels built into both side of the upper battery chamber. The airflow is driven by the rotation direction and movement of the main brushless upper motor housing when energized by the magnets under the battery chamber housing.

*** NEVER DELIBERATELY INJECT WATER THROUGH THESE TWO VENTILATION PANELS ***

From the operator point of view, the motor rotation creates a suction effect by drawing air from the left ventilation panel into the rear of the battery chamber where most of the electronic circuitries located, down through the motor chamber and expelled out through the right ventilation panel. Similar principle as how the rear-side-discharging and bagging method works.

This effective air cooling method allows the battery chamber, internal circuitries and the motor to run cooler under hot temperature conditions over any other walk-behind EGO mowers. This is important because these models houses the highest wattage brushless motors with the highest Blade-Tip-Speed rpm EGO currently has to offer for the walk-behind mower lineup.

In order to take the full advantage of this air cooling feature, the operator needs to make sure the air ventilation panels as well as the internal air channels are free of debris.

For LM2200SP and LMX5300SP, both has screw removable panels, operator can remove both panels for cleaning.

For LM2230SP and LM2240SP that does not have screw removable panels but clippings, best to use a soft brush to clear the panels without breaking the clipping that allow the panels to attach to the upper battery chamber housing securely.

After the ventilation panels are cleaned, use a leaf blower and blow from the intake side to eject any internal grass clippings, sand and dirts out of the internal chamber of the mower after each mowing job is completed.

Now the 22" mower's motor will be able to perform at its maximum potential again.

Maximizing the Under-Deck Airflow:

Unlike the 21" poor rear-side-discharging chute design, the 22" rear-side-discharging chute allows the mower to gain longer battery runtime, higher suction/ vacuuming, grass blade lift and massive amount of airflow.

During maintenance cut with the stacked SelectCut dual blades setup, it produces small 0.70" (mulching-blade) or 0.75" (High-Lift-blade) clippings between the stacked blades. Rear-side-discharging allows the smaller clippings to return back into the lawn for added nutrients without thatch buildup over the soil layer.

Do You Know: 1100 Series - LM2206SP and the twin commercial LMX5300SP's cast aluminum deck offers 100,000x faster heat dissipation rate over the polymer or SuperComposite (PC/BPT) deck?

The cast aluminum modes has larger intake and exhaust panels on each side of their battery housing. The air flow driven by the main motor keeps the motor, battery and internal circuitries operating at a much lower temperature than the polymer or SuperComposite (PC/BPT) deck models under any hot weather conditions.

This material's temperature regulation ability also prolong the longevity of the electronics in the mower as well as the battery(s) used in these mowers.

Most people chooses a lawnmower based only on the motor power and deck width without inspecting the under-deck design. Next to the Blade-Tip-Cutting Speed, the under-deck design actually influences the power of the energy flow under the deck to produce the optimal cutting and clipping size performances.

With 1000 Series LM2236, LM2242SP and 1100 Series LM2206SP Ver. B (Near-Silent Self-Propelled System) all having 22" deck width and 21" length SelectCut blades setup with the same motor tuned differently; however, the under-deck design are vastly different.

1000 Series:

- Larger diameter of protruding center molding motor housing to accommodate the powerful motor securely. Requires more flexible SuperComposite material to minimize the motor vibration. Similar to the 21" polymer mower deck design.
- Build-in mulching plug with sliding mechanism that decreases under-deck volume for convenience.
- Lighter SuperComposite deck with center focused weight distribution from battery and motor that introduces front wheel lifting especially when bagging.
- Smaller front wheels and flexing retractable handles introduces more vibrations and fatigue mowing experience.
- Some may argue that it's similar material & design to the Honda's HRX Nexite deck but Honda has much more open space around the motor.

1100 Series:

- Small diameter of strong and thin cast aluminum under-deck motor housing similar to a commercial graded dedicated mulching lawnmower.
- Mulching plug insert that takes minimal space & time to install and easy to clean without clogging.
- Heavy none-flexible cast aluminum strong but thin deck. Evenly distributed weight throughout the entire deck down to the wheels without front wheels lifting when bagging.
- Large front wheels and one-pice stiff handlebars introduce less vibrations and fatigue mowing experience.

Based on the images provided, the under-deck of a 1100 Series shows a lot more space for grass intake volume and energy flow through the air for the grass clippings. It provides more lifts for grass blade when mulching, bagging or rear-side-discharging with less chance of clogging. One can't really argue with how physics works.

Even the upper-deck structure design shows much lower profile on the 1100 Series for allowing the lawnmower to get under brushes, downspouts and hanging over obstacles without the higher deck, mulching plug lever and height adjustment lever sticking out of the upper-deck.

We all choose a new lawnmower last for years to come. It would be a good longterm investment to choose the model that will provide the best cut and clipping performance while also providing the most enjoyable experience every time we mow the lawn.
