V-TEC feed roller for Logmax 4000/Komatsu S82 harvester heads

Komatsu C93 V-TEC

"I should've ordered these two years ago. Huge difference on grip and performance.

One hell of a change

- Power increased
- Winding trees goes through smoothly
- Harvester head is more silent
- Able to decrease gripping pressure
- Excellent grip
- Big or small trunks without a problem
- Cheap price
- Seals do not freeze (open structure prevents water from accumulating)"

"Incredible grip. The most noticeable difference compared to previous wheels is that the tops go through intact. Feeds well forwards and backwards. Makes calibration (pruning) easier because the surface of the wood remains smooth compared to spiked wheels."

"We bought our first V-tec feed wheels in September 2019. We have also used original feed wheels occasionally. Our logging sites in Ilomantsi are mainly in Finnish swamps. The average diameter of the trees is only 120cm. They are long and "thin" trees. The feed wheels have accumulated more kilometers in terms of distance than on the thickest sites. When you do windthrow logging under the snow, the feed wheels are exposed to, for example, contact with rocks due to the motion range of the grapple. The V-TEC feed wheel is easy to maintain. The worn blade could be sharpened to its former state even in the forest. The open structure of the feed wheels prevents them from clogging, which is a plus. Reversing is also successful. So, I will order new V-TEC feed wheels for the Scorpion on March 31, 2021"

"Intelligent ones! Compression pressure can be dropped intelligently, 90 reduced to 70. The feed speed increased. It immediately picks up the wood. Only small marks remain on the tree = does not break the bark. I liked it!! Not noisy. Goes smoother than the previous spike rollers. It's silly to be stingy with the rollers. The money was not wasted."

Ponsse H6/H7/H8 V-TEC

"We have had two years - about 5000h V-tec feed wheels on Ponsse.

They have held up well. I initially lowered the compression pressure by 10 bars. Good traction. Sharp and easy to sharpen with a grinder.

There is no going back to spike rollers. I also want V-tec feed wheels for another machine.

We also do some multi-tree handling. Occasionally, branches get caught on the sharp edge spikes of the V-tec feed wheel. Perhaps I will purchase V-Tec multi-tree wheels for these work sites."

"Since 2017, we have been using V-Tec feed wheels in Ponsse's 5, 6, and 7 harvester heads. The contractor complained about the damage caused by so-called sea pine spikes. At that point, we decided to test MenSe's V-tec wheels, which were still in the development phase. In collaboration with the manufacturer, we made fine adjustments to them. The contractor measured the deflections and approved the work result.

Compared to the spike and so-called standard straight rib feed wheel, we have noticed that the traction of the V-tec wheel is excellent. There is no slippage with V-tec wheels. The standard wheels slip at the base of the pine tree and cannot be driven twice because the surface is damaged. In short, the advantages of V-tec from our perspective: Traction, reverse capability, can be driven from both sides = wheels are reversible and do not cause harvesting damage."

Log Max 4000 V-TEC

"I am very satisfied. I have had the Log Max 4000 with Mense-V-tec feed wheels for about two months. The feed wheels run smoothly, have a good grip, and stay clean if it is below -20C. In freezing temperatures, the snow freezes from the side of the flange towards the grip due to the heat. However, it does not affect the grip and it is not a problem."

Ponsse H6/H7/H8 Multi-Tree V-TEC

"I often have projects where I process both energy wood and timber at the same time.

The V-tec multi-tree wheel works well for both. It would be difficult if I had to change wheels when working with different qualities.

When comparing the V-tec to other feed wheels I have used before, the GRIP is very good when operating at normal pressures. They don't slip. In our area in Northern Savonia, the spruce trees are lush and especially the tops are difficult to handle. I got frustrated with regular wheels getting clogged. V-tecs never lose grip and they also don't get clogged. At first, I was afraid that the sharp spike of the V-tecs could cause damage to the logs. The deflection has been measured and it was not a problem. The spikes touch the trunk over a large area, so it doesn't sink into the wood. The wood is not blocked if the V-tec causes damage to it."

"These feed wheels provide new features for the grapple. Excellent grip. Pine bark passes through the fingers and the grip is maintained. Working with birch became easier and making tree tops is done better. The biggest difference was noticed when working with big trees and birch. These will also be used in the future."

John Deere H413 V-TEC

"Very good grip. Does not damage the log. Good durability -> driven almost 8000 h. Holds well in both directions. The ribs interlace and in the beginning they round off. No disadvantages have been noticed. Does not clog. Compression pressures lower than when using normal spike rollers. DOESN'T SHAKE"

"You have really succeeded with the V-TEC feed wheels. They work perfectly in multi-tree processing and roll smoother than rubber-coated steel wheels. So we are really satisfied!"

Ponsse H6/H7/H8 V-TEC

"MenSe's service is fast.

We already have V-tec feed wheels in several machines. We have liked these wheels. We got a new machine now and immediately switched to V-tec.

V-tec cleans well. Bark does not accumulate. Interlaced ribs center the trunk upwards, it does not fall down. The wheels center the trunk to the bottom of the grapple. Good traction. No slipping. Does not damage the surface, so no harvesting damage.

All wheels wear out over time. They are not eternal. However, V-tec wheels can be sharpened/restored, so the lifespan increases. In addition, Ponsse 6-8 Vtec can be reversed. The outer spikes are new twice."
