A Fun Build to a Nice Working Model
on December 15, 2019
Posted by: Reka
This was a truly enjoyable build and my first large one since I was a kid. I especially appreciated the numbered bags as they made it possible to find pieces in a reasonable amount of time. The pneumatics worked great with no rebuilds and, as usual, the instructions were excellent. I was really impressed with how simple the system was, kind of like a reverse train engine where the rotating motor generates linear motion which fills the system with air. The only real issue I had was the flexible pneumatic tubes gather dust and cat hair like nothing I've ever seen!
I would recommend this to a friend!

Great set, overpriced though
on July 31, 2018
Posted by: Quoted14Hydra
This is a good set by itself, not looking at the price. The motorized and pneumatic functions work perfectly and are really cool and fun.
Although I'm not a huge fan of the looks of the machine itself, I'm happy to see that Lego technic is using some different colors in their sets.
The small details in this set are on point. Lego technic once again has mixed the standard technic parts with regular system bricks to make something beautifully detailed and fun to play with.
On the other hand the set is overpriced. I do realize that the power functions and pneumatic pieces raise the price, but I think 130$ or maybe 140$ would have been more appropriate.
If you really have your eyes set on this set, then by all means buy it. It is a great model.
I would recommend this to a friend!

Excellent Build - Love the Pneumatic System
on August 29, 2018
Posted by: Chookie
This lego is perfect for those who enjoy a nice build with a few bells and whistles. The pneumatic system works very well, and gives it an extra wow factor. Also given what you get, I believe it's in the right price point. Well done lego team!

Pnumatic System Needs Improvement
on August 26, 2018
Posted by: LegoFanMatt
I was very happy with the building process, I liked the new colors and the small details that were included in this build. However once finished I was very disappointed with the pnumatic system. The power functions only really half worked. The arm raises and lowers the way it should, however the "blades" that are supposed to open and close seem to require manual assistance. You can see them trying to work, but just can't do it under it's own power. It's not too bad if it is just a display piece, but it's not too good if you want to be able to play with it as it is advertised. I was very disappointed in the end, and found myself wishing that Lego had gone fully electric with this model rather than using pnumatics.
No, I would not recommend this to a friend.

Thanks for your review. I’m sorry to hear that your LEGO® Forest Machine isn’t working as expected. From what you’ve described, it sounds a little rebuilding might be in order. You’ll want to make sure that each part is in the exact position shown in the instructions and that everything’s pressed together tightly (except the gears, which need some extra room to turn). You should have much better results!

If you need a hand troubleshooting the build, you can get in touch with our friendly Customer Service team at LEGO.com/Service.

Thanks for your review! This set features LEGO® Power Functions with pneumatics. Turn on the battery box and you'll be able to twist gears that allow the boom to raise and lower and the grabber to open and close.

It lacks in playability, makes up for with parts
on June 2, 2025

Verified Purchase:No
It’s hard to remember when I first built it, but rebuilding some of my older sets to finally get them on display, this one came to the top of the list for re-assembly.
Good variety of parts, including some basic pneumatics, as well as a large PF motor and battery box. I kind of wish it had a traditional pneumatic pump over the electrified power pump that it does include.
It’s large, with the cab and boom point forward, at least 18” from the brush cutter to the tail end, wish it had a mock engine instead of the batter box.
I’ll echo what others have said, some of the boom functions seem tricky and/or stubborn to get to function properly on the first go around.
I’ve never built the B model, but it’s an old enough set to actually have one, so that’s always a plus.
Overall a good display unit, kind of fits in with some of the farm based and construction based technic sets.
I would recommend this to a friend!

Thank you for your review, it can definitely feel refreshing to revisit older sets and put them back together! We hope this set stands out amongst the the others that you own, we'll pass the comments to the design team to help with any future pneumatic/functional design aspects.
