Very cool! You can look on ebay or call Zimmermans for manuals. Welcome to the board!

got it home this evening and made 4 passes down the runway I'm building in the backyard, accomplished more in 15 minutes than I did in 4-6 hours on my Kubota. will check out Zimmerman for the maual, does not look I will need much though, runs great and moves lots of dirt, just what I was after.

I am just outside if Redding CA, got a firm grasp of most thing
s on it, there is a lever just below the gearshift I don't know what it is yet? I was thinking a PTO engagement but it does not seem to do anything in either position, it is a short lever, maybe 6-7 inches. will investigate further this evening and post a pic of it. the tag on the blade frame has the model number as BH-ADH , it has a American equipment tag from Oakland CA.

figured out the short lever is the pto engagement lever, just wasn't moving it far enough. pushed dirt for about an hour tonight working fairly hard, pressure drops off at idle when hot, checked to make sure it was pumping but it is low at idle. do not have a manual as of yet, need to know what oil goes in where so I can get them all changed this weekend. from what I read it uses 50wt non detergent oil in the trans and final drives, I am assuming the engine would be the same. how much oil do I need to buy? I think I read somewhere last night here that the finals hold around 8 gallons? any standard service info would be appreciated.

No: Make sure you use a good diesel oil in the engine. I myself am not a fan of the 15W-40 Diesel oil, I would use a good severe duty 30 weight diesel oil, Also make very sure you have oil in the injection pump governor since your tractor most likely has a Timken governor. Also check the oil in the injection pump and the air cleaner. Use the same oil as what you use in the engine. I do have a book I can look later this weekend.

Kevin · October 07, 2010, 02:03:33 PM

is it fairly obvious where to check the oil levels on thise two? I am a lead tech in a motorcycle shop for the last 15 years and a A&P aircraft tech, but frankly don't know anything about diesels, other than theroy of how they operate. driving the tractor, no problem, just not familiar with serviceing it.

ok, I think I found the injection pump fill, a little screw on breather cap, there was little to no oil in there, added some, but do not see a level mark, where is it or how much? I am guessing the governor is just forward of the pump and the throttle lever connects here, where do I add to it or check its level? going to replace the oil pressure and water temp gauges tonight to get a firm grasp on what its doing while running, this morning while cold it shows 20-25 psi at a fast idle, ok? going to try and source a fuel and oil filter.
thanks Kevin

I've used the 15-40 in my AD with no problems. The 30wt would be fine maybe better in hot weather, for an old worn engine. The oil filter is probably a brass screen and needs to be washed. No replacing of anything. The oil fill line for the injection pump is just up from the bottom of the pump, maybe a "wing" nut style. It shouldn't hold very much. Governor is the same setup with a filler plug on top.

My AD when its cold holds about 45 lbs of oil psi. When I work it hard, it will drop to about 15 or 20 psi. If I'm not mistaken, thats about what the book calls for. There is an external oil pressure adjustment on top of the oil filter housing. I've never adjusted any of mine, so I can't really give you the rundown, but it sounds very simple in the book. I think yours will be fine, as long as it has about 5 or 10 when its real hot.

The bottom comes off the air cleaner, with some spring clamps, or with wing nuts. Dump the old oil out, and wipe it out, then there should be a fill line to where the top of the oil needs to be. If it has a pre cleaner, take it apart also. Its just spring loaded and turns. I never had a good one on a tractor to clean. I think just dump out the big stuff and no oil is needed.

50 wt in the transmission, and that fills everything. 8 gallons, I'm pretty sure.

Make sure to keep the fan belt tensioned. If not it causes the fan to slip, and not cool properly. Could cause serious problems...
