these loppers did not preform well at all, when tried to cut a 3″ tree
could not cut at all. Handles seemed to want to break instead of cut limb.
It also requires a tremendous amount of stregnth to operate loppers.
preformance ratings of 1 to 10, I give them a three. Needless to say, I returned item.
Yup, it takes strength and effort to cut the maximum diameter stems, but I’ve had three of these, and they outcut anything less. Ones with more complex leverage engineering are too stiff to open and cut with quickly, and they invariably end up coming apart as an impatient user tries to torque and twist them.
No other lopper cuts nearly the diameter of these. They have earned their purchase prices many times over eleven years.
I’ve been a landscape contractor for 25 years and have used all sorts of pruning tools. This is a great heavy duty lopper, however this tool is not a finesse tool. I use it for lopping off small tree branches–suckers—de-caining large shrubs and shrub removal. The Corona 37″ lopper cuts very well(it cuts much better than a smaller lopper) and is only limited to the strenth of the person using it. I’m sure it would cut a three inch branch but most people are not that strong. I use a pruning saw for anything over 2 inches.
I love good hand tools and have bought and inherited many of the best. After much shopping research, it appeared that this Corona Clipper 37″ Professional Super Duty Bypass Lopper would be a great addition to my tool collection. Unfortunately, I can give it only two stars for being ruggedly built and having a good sharp blade, because the performance has been a disappointment.
Recently, I’ve been trimming a lot of trees, (honey locust, cottonwood, silver maple, and oak) and I found that the lopper took a good deal of force to trim off small diameter limbs (<3"). For several weekends, I worked on these trees (14 trailer loads of brush and limbs) and I kept trying out the lopper. Though I am above average in strength, I found that I was doing much more work than the lopper was doing.
I just now came out the yard after attacking some 25 year old Manhattan Euonymus bushes. They were very over-grown and 10 feet tall. Some of the base vines were over 3″ diameter. I wiggled my way into the tangled mess with my Corona lopper and found out quickly that this was the wrong tool to cut the base vines. To open the blade jaw, even for a small diameter cut, required that the handles spread open very wide, too wide for the tight quarters I was in. So I pulled out some old loppers I had, Fiskars 24″ geared action. It did the job well. After pulling out the vine/limbs, I decided to test the cutting force of the Corona versus the Fiskars. The Fiskars required less effort to cut through the same limb. That’s when I decided to write this review.
The Corona product has good quality materials, but the design is a dinosaur for effective cutting.
I purchased a pair of these loppers several years ago for $150 and have used them for over 100 hours of work. Compared to a $40 pair of loppers which I purchased with a “lifetime warranty” and then bent the same afternoon, these loppers are wonderful. The hardened steel is extremely hard and around 1/4″ thick — I cannot imagine what it would take to make the steel fail on these loppers. As far as the handles go, I did eventually manage to break one of the handles after a couple years which I replaced with a custom-made handle fabricated from oak and some angle iron. These loppers slice through green wood like butter. The problems I’ve had with the handle originated from cutting through a dry branch which had been down on the ground. While these loppers are not unbreakable, they are by far the toughest loppers I have come across.
