My TM-86H is now up and running. The problem was a lack of sufficient oil in the tank. As I said in my original post, my
chipper was delivered just hours before bad weather was closing in and in my haste to get up and running I purchased what I thought were 4 5-quart containers of oil without noticing that they were now 1-gallon containers. Yesterday when I finally got the
chipper back out with enough time to sort things out I discovered that the oil level was low in the tank and checked the “can” sizes online to confirm the mistake.
As I previously posted I am using this
chipper with a BX-2200 Kubota which is specified to have 16.7 Hp at the PTO shaft. This is pretty much the minimum recommended for driving the TM-86H.
My experience during the first couple of hours of using this
chipper is as follows.
1. The quality of construction is very high and entirely consistent with heavy continuous use
2. All operating controls are convenient to work with and access to hook up to the tractor is very convenient once a drive shaft of the proper length is available.
3. As I previously posted, it is not possible to properly attach this
chipper to a BX-2200 Kubota unless a quick-hitch is installed on the tractor. Cutting the drive shaft will enable a power connection but it will not be possible to set the
chipper flat on the ground. That can only happen if the attachment to the
chipper is extended at least another 3” or so back from the normal Cat 1 hitch location. This is not really a problem in my opinion because the quick-hitch is virtually a necessity anyway in order to expedite hook-ups and it is not an expensive accessory. The requirement for it however is something the customer should know about up front. I did not and
WoodMaxx sales seems skeptical of the need. Had I followed their recommendation to cut the shaft to directly connect without the hitch, I would now be forced to purchase another drive shaft.
3. With less than 17 Hp I am limited to pine ~3” or less in diameter and I am choosing not to chip hardwood over 1”. These are quite acceptable limits for me. Any hardwood above 1” is firewood. My pine limit may also be a bit conservative as the pine I have so far chipped is dry and I’ve been operating with a feed rate at about 7. I haven’t yet played with feed rates as thing were going very well until I choked on a larger piece and stopped operation for the day at that point.
4. The condition which choked the
chipper and stalled the tractor was a single soggy 3” pine limb. After opening the cutter housing we found the exhaust chute plugged and casing full of chips. It took a couple of clean out attempts before we got the hang of properly clearing it out. The lesson learned was to be more conservative about rejecting big water-soaked pieces. Dry and newly cut material seemed not to cause a problem. Also I am still learning how to manage the feed control and rates to best deal with problem situations. Of course this is an issue which is partly the result of operating with barely enough PTO power.
5. The only aspect of operation which I found annoying was the sensitivity of the feed control bar to false depression by passing branch material. I’m not sure anything could be done about this without seriously compromising safety. I am going to see whether it is possible to change the position of the bar so that it is a bit more under the hopper where it would not be constantly vulnerable to passing material.
Over all I am very impressed with the design and function of the TM-86H, especially as it is being supplied with the absolute minimum PTO power. However I still feel that the customer support upon initial delivery was inadequate. I only discovered the requirement for the quick hitch after the
chipper delivery which further delayed my setup. Then
a couple of weeks later after the quick-hitch was delivered I was in a panic situation with bad winter weather closing in just hours away. Despite multiple calls for support I have not received any
WoodMaxx assistance in resolving this issue.
