I've only had the Wisent for a month, and I have a custom guy behind me running a Franklin 132, so I haven't ran the Wisent much at all.Looks like an understandable progression earache. How have you found the wisent so far? We run a single bunk 1010 tj and a ponsse buffalo with good results.
Do you cut all short wood or some longer logs?
Bitz, surprisingly you will find you can move wood faster with a good single bunk if the skids are short. We have found the tipping point to be around 200 yards.
I have kept myself in the loop as far as ponsse forwarders for a while now to see if they are worth it and where the weak spots are. yes, the center sections and bogies are definitely not designed for the great lakes region. The center sections hold up well once they have been disassembled and plated, then regularly greased. According to Ponsse, its worse to load the back bunk only. This one has had the updates to the center section. The rear bogie bearings are another spot to not let go once the bearings start getting loose. Bearings on this one are in good condition. As far as using just the front or rear bunk, its an option I put to use maybe 10% of the time. Good to have options. I put 1,000hrs per machine per year, so im not wearing them out. So, the upside to that is once I make a serious repair, it lasts.Be careful with the wisent loading the front half and not the rear. They are a pretty light machine as forwarders go and don't have the toughest center section. If you only hauling front tier it puts a lot of stress on the center pins and bearing due to the lack of load balance on the rear axle.
We ran a caribou (very similar to wisent) for a few years and learned some of these things the hard way. Also jack up the front and back to check for play in the bogie bearings. When they get bad they bind the axle and start dropping metal into the bogie housing. Its about 12k per side on the bogies, maybe more.
You are right, they will skid over dirty water with tracks on. Very, very good in soft ground.
We have had excellent service from Ponsse and have heard very little bad about them
What sort of harvester are you running?
Without any support...that's tough. K-I-S-SYeah there is no dealer support for anything down here. No one knows how to work on these machines. I'm on my own. Thats part of why I'm apprehensive to step up to a machine that is not totally mechanical. There is very little electrical on my 132. Its got the five lever loader and the manual transmission. No frills here. She packs the wood out though. 4mbf per hour yesterday. Short skid is key though like 1270 said. Its not unusaul to have a 1/4 mile skid from the back of the woods to the landing. In some cases I've done 1/2 mile from woods to the landing. That gets old. I did that this spring. The woods still had frost, but we never would have gotten a truck up through the chisel plowed field. Had to run it to the road. Usually I get a little extra kick from the mill for that though.
yikes!The site we are logging now, the skid is over a mile. Doing good to get 10 cords out an hour with 2 skidders.
