Customer photo review of Ranew Outdoors Firminator G3 Planter 4ft, 5ft, 6ft & 8ft | 3 in 1 Food Plot Implement | 3pt Planter | Discs, Seeder & Cultipacker | For Tractor

The week before leaving for my mule deer hunt in Wyoming, I seeded the area surrounding the new runway at Wertheimer Airport in Norman. This past Tuesday, I returned to finish the job and was pleased to see that the seed I planted just two weeks earlier was already germinating and coming up nicely. These pictures show the freshly seeded areas alongside those planted two weeks ago. It’s a great comparison and a good example of what proper seedbed preparation and planting can accomplish. I used my Ferminator G-3, which is one impressive piece of equipment. It prepares the seedbed, plants the seed, smooths the soil, and firms everything up for good seed-to-soil contact—all in one efficient operation. I’ve owned and operated several no-till drills over the years, but I can say without hesitation that the Ferminator is the most efficient and versatile seeding machine I’ve ever owned. There’s something pretty satisfying about returning to a job and seeing those first green shoots coming through the ground. That’s when you know your hard work is paying off!

Customer photo review of Forax Gas Powered Mulcher | Model GP40 | 40" Cutting Width | 14-15 HP | For Tractors

Seems to be in order delivery wasn't able to use lift gate but tractor was able to take pallet off the truck bed. No damage to machine after visual check. won't know how it runs until rain stops. Staff at RippingitOutdoors was very quick to call and double check the type of backet needed for the unit to ensure the online order matched( to fit my skid steer quick attachment on my l2501 Kubota). Explained the teeth & belt could be ordered through them directly over the phone when/if needed as well as selling other types of custom made brackets for Utv's ect. All around Great customer service and would purchase from again.

Customer photo review of Ferntree Mini Excavator Forestry Mulcher | Model FF-L Series | 22"-30" Cutting Width | Machine Size 2.5- 6 Ton | For Mini Excavator

easy buying process and great communication. Mulcher works great, easily clears overgrown brush and even mulched a 5" thick mulberry tree fairly easily. running it off of my old 331 bobcat with no problem powering the drum at all. Only small issue which isn't a big deal is that the supplied hoses are about 16" too short to operate a full range of motion.

Over all built well. I like it is all cast iron and metal and not plastic. Had to modify fertilizer disc mount to fit correctly, nothing major, a little grinding. I modified the center link hitch point to accommodate my John Deere quick hitch. Have yet to plant with it but I’m sure it will work perfect. Love the grease fittings everywhere. Reminds me of the old farm equipment I grew up on, and still use periodically.

My firminator RT was delivered in good condition in ND. I will be using it next week. I have a 45 HP John Deere tractor that is supposed to lift 2000 lb but really struggles to lift this 6 foot firminator RT. I will just have to use in as a two pass operation for now. I do wish there was a better operating manual for this unit. Maybe that is something you can work on. I will give you an update once I start using it in a few days.

It’s built solid. It handles Field grass hip high pretty well. With the maintaining the field grass after the first cut, the pasture field is starting to look like a lawn. The 84 inch with the best thing to get for 8 acres. It’s best to order belts for back up in the event if the belts were to break. But overall, I like the product quality is good.

When I think of ripping it outdoors something else comes to mind, but I digress. This spreader is awesome. Works like a champ. The hopper is big enough to do my 1 acre lot for my applications. Just load once and go. I would highly recommend this spreader. It saves a ton of time and is a quality product.

Put this on Kubota 900 with winch hookup. This thing is a beast (within reason). I named it ‘Homie”, cause Homie don’t play. It will take care of stuff up to about 2” in diameter. You still have to remember that this is NOT like the ones on a bobcat or larger machinery. It does have its limits. But all in all I am very satisfied with it. Now on to the good part! The staff at Ripping It are outstanding! Especially Kayla in the office. She has gone above and beyond on making sure everything went right, from ordering to questions about installation. This young lady would be of great value at ANY company ! Her knowledge and personality are like over the top. This is my first experience with Ripping It Outdoors and I can only say positive things about them. With all that being said, I do fill out reviews on things I buy, AND I give a honest review. If it’s bad then you will know it. But if it’s good, well I tell the truth ! Again Kayla, from the bottom of my heart, a great big THANK YOU for all your help and just talking to you. I feel like we’ve know each other for years!
