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.

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

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.

Put this on Kubota 900 with winch hookup. This thing is a beast (within reason). I named it β€˜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!

TENT is easy to put up , material is tuff as told....only complaint is that i wish the bottom had about 3 to 4 inches overlap towards the inside so i could install a 2 x4 or something to help hold the tent down in high winds we have here in virginia thanks

Hi, my name is Ken. I’ve had a great experience with Ripping It Outdoors. I purchased a Forax Hp40 Mulcher for my mini excavator. Kayla Patterson is who I dealt with from the beginning until I received it at my house. She has been wonderful to work with and looking forward to working with her with any other orders I purchase. Kayla answered any questions I had and kept me updated throughout the whole process, can’t say it enough just a wonderful person to work with!!

Forax Ultralight Mulcher | Model HP40 | Cutting Width 40" | Carrier 2-4-Ton | For Excavators

These are great feeders if you don’t have any feral hogs but if the hogs tear off the wiring harness from the timer to the feeder motor, you’re disabled. Then, if you ask for help from Outback, they refer you to the dealer but really you’re on your own for parts and repairs. I have three Outback feeders that work as designed. They’re 13 years old and have always served well but this feeder misses the mark by a very high margin. I’d NEVER buy this product again. Feeders need to be dependable and this unit is not.
