All I’m saying is be cautious. I saw a lot of great reviews so I went for this planer. Straight out of the box it was tripping the breaker. Went “under the hood” and noticed the start capacitor was bad. They sent me a new one and still the same issue. As it approached full power it would trip. I tried to check the centrifugal switch but the fan is mounted so tight to the motor I can’t access it. Now they want me to pull the motor off, pay or spend the time building a crate to crate it, and send it back. I’ve already spent countless hours trying to trouble shoot fixing their faulty machine, now I need to spend even more time getting the motor out so they can see what’s going on. My time is very valuable to me and this seems to be a case of “me paying them so that I can wash the car”. They sent me a faulty machine and want me to do the work fixing it. I was initially told that if there was something wrong with the machine, they would come pick it up and repair or replace. But this all just means more time that my shop doesn’t have a planer. I’m mostly happy with my other grizzly products but this one has been an absolute nightmare (especially due to the size of it). So it’s more a matter of luck when choosing this machine apparently so again I’d be cautious.

No, I do not recommend this product.

Amazing machine!

I have a smaller cabinet shop and only had a 15'' Grizzly Planer before moving up to the 20". You cannot go wrong buying either the 15" or the 20" with the spiral cutterheads! The 20" Grizzly planer w/ spiral cutterhead is a workhorse and will make Hickory seem like you are cutting butter! Great value for your money!

Yes, I recommend this product.

planer works well but the roller with the foot pedal slam's down out of no where a lot when you are pushing it, also one of the knobs were broke from the factories. machine functions very well. I am happy with it.

Yes, I recommend this product.

Happy customer

Totally satisfied with machine so far. Delivery was quick and well crated. No signs of damage in shipment. All loose items packed and secured. Easy assembly no problems with alignments. Good detailed assembly instructions. Proper warning tags to prevent start up before adding gear lube. Mobile lift wheel and base wheels solid steel and easy to operate. Moving the 800+ lbs of cast iron and 5hp motor around the concrete floor of my shop is a breeze. No need for realignment to any of the rollers. Operated initial start up was normal and very smooth and surprisingly quiet. Started test cuts with dry 8/4 white oak 18 in width No problem at both speed rates. Cuts were butter smooth and even across the planks. Measured equal thickness end to end NO SNIPE! This planner is the quiet machine in my shop now. My vent fans are louder than this beast. I will be running 1000 bd ft white oak soon and we’ll see how she holds up. Pleased as can be with this purchase.

Yes, I recommend this product.
