Hard as stone. Its had cow or buffaloes on it for a millennium. About 8 inches is all I need to plant hemp. The plant material will rot into the topsoil providing a good amount of nutrients where its needed, on the top 6 inches

A thinner coating is harder than a thicker coating, thats why a few thinner coats will resist scratching better than thick coats. Looks Great!

I did a short test run and did not lower the plough completely, but the 3 bottom plough moved through centuries old grazing land like it was pulling a small wagon at depth of just over 6-7 inches. I chose not to use coulters as even with short grass it tends to clog the ploughs. Tomorrow I will stake out a 10 acre plot with flags and wait for a good day to put steel to earth. The David Brown 990 6 speed live drive is just a wonderful joy to drive and each day I'm getting more proficient in her operation.

You can use VM&P Naphtha to help try time, its a little hotter than regular paint thinner, but with oils based paints they get harder when thinned and dry quicker

How are you applying the paint, brush or spray?

reminds me of radio, you have to use your imagination, that's good

Replacement engines were grey for some types of equipment and blue for others. There were manufactures of equipment like Panzer and others that used blue as the colour of their machines and in those cases the engine was painted the same colour blue as the equipment by the manufacturer. Wheel Horse used red as the colour of their engines until the very late 1970's, the twins were the first to go black, but soon after the single cylinders also were either paint black by wheel horse or came that way. Ford blue and Pontiac blue are both lighter than the blue Kohler used on mostly service engines. Most kohler generator sets, welders and other service equipment came with Kohler blue engines, when replacement engines were ordered they were sent in grey colour for engines that were painted by the OEM manufacturer and Blue for engines originally supplied as blue. BTW, replacement engines were designated as such on the serial number and generally did not carry the same spec number as the original engine, but rather one that was compatible from current stock. This is how you determine if your engine is original. Hope this helps.

Can you specify or show/describe the colour blue. They had a factory blueish/grey, but some manufactures also painted them.

Yep, you’ve gone full rotisserie

Again I screwed up. I referred to your tractor as a C-121 in my original post and then referred to my mistake as calling it the correct C-141 model in my apology. I can see how you could be confused, lol. A chap after my own heart. I like and respect how you feel.

My apologies for referring to your tractor as a C-141, but my info still holds true. I thought your tractor was a C-121, maybe that was another recent post from someone else. Did you notice the serial number was over stamped on the second digit? The 16hp Kohler is a beast. While the 16-18 hp magnum twins a powerful, smooth, and quiet. I honestly don't believe they have more torque than the K341. I know they aren't nearly as reliable, durable, or inexpensive to rebuild.

It's a 1979 C-141, should have had a 14 hp Kohler k321 in it originally. Looks Belgium made

The C-121 was a newer (1978-1979) version of the C-120 (1975-1977), Wheel Horse and Toro often just used an addendums to the older parts and service manuals for newer models. There may be a C-121 Part/IPL manual out there on PartsTree, but it is probably just an updated microfiche file from Toro. You can use the C-120 parts and service manuals for the C-121 and consult the addendums for differences. The C-121 was made 2 years and in 8 speed and Hydrostatic drive models 1978 C-121 8 speed was model 81-12K801 Hydro was model 81-12KS01. The 1979 C-121 8 speed was model 91-12K801 and the Hydro was model 91-12KS01. There are 4 or 5 addendum's for the later model C-121 so for changes made in newer models and others for Belgium made models. I have attached the addendums here and the service manual. The way to read model numbers form 1976 to 1980 Wheel Horse Tractors is the first number is the year, not sure what the second number means, the next two numbers are the horsepower, the letter stands for the engine brand, K= Kohler, B= Briggs, etc. The next number was was 8 for a 8 speed, and 6 for a 6 six speed or S for a Sundstrand Hydro. Model 91-12K801 was a 1979 12 hp kohler powered 8 speed Model 81-12K801 was a 1978 12 hp kohler powered 8 speed and Model 81-12KS01 and 91-12KS01 were 1978 and 1979 hydrostatic units Tractor 1975 C-100 C-120 C-160 8spd IPL #803983.pdf Tractor 1979 C-121 8-Speed 91-12K801 TIPL.pdf Tractor 1979 C-121 8-Speed 91-12K802 Details & Attachments (1).pdf Tractor 1979 C-121 8-Speed 91-12K802 Details & Attachments.pdf Tractor 1979 C-121 8-Speed 91-12K802 TIPL.pdf Wheel_Horse_1978_b-c-d-series_service_manual.pdf

Yes very nice Gantry, I may build one my self. very compact and handy

Have you looked at the parts or service manuals?

Rods like pistons are sold in off sizes, over sized for pistons and undersized for rods. That way if you have to remove material off the crank you can still purchase a rod for it.

Very good start. Looking forward to seeing this project move forward.

Very nice pictures, enjoyed them. Thanks

The pictures were a joy to see, thanks so much for sharing. What's the story with the Uni-Horse 6 8, is that a Wheel Horse?

Very Interesting development in this tractor. It is not a 1965 David Brown 990 Selectamatic, but rather a 1964 David Brown 990 Implematic. The Model number is H990/UA, s/n 471597 (December 1964). The "U" the model number means it was special for the American market, and why it has 990 Selectamatic tin on a 990 Implematic tractor. There was an import deal with Bolens to the American market. The reason for the color change was to make them look like Bolens tractors. The "A" meant it is an agricultural variant. The Implematic had the 6 speed Hi-Lo with 2 more speeds in reverse and the Selectamatic was a 12 speed 4 range (low slow, low, high slow, high), with the ability to up shift from 1st, 2nd, 3rd and 2nd to 3rd and to downshift from 3rd to 2nd in any of the ranges without stopping. The David Brown 990 Implematics made for the European market were red with a rounded front hood. Still the engine and drive train are extremely proficient for agricultural work. And on the collector side a very unusual tractor here in America as CASE was selling a comparable tractor at their stores and had the benefit of a huge name recognition here compared to David Brown. In another interesting piece of trivia the management of David Brown saw a classified advertisement in The Times in 1947 offering for sale a High Class Motor Business, which turned out to be the sale of Aston Martin. David Brown acquired Aston Martin for £20,500 and, in the following year, Lagonda for £52,500, followed by the coach-builder Tickford in 1955. David Brown subsequently concentrated all the Aston Martin manufacturing at the Tickford premises in Newport Pagnell. The David Brown years saw production of the legendary DB series of Aston Martins, which were featured in some James Bond films. David Brown also had connections with Vosper shipbuilding, and Delapina and Radyne machinery. Both car companies were sold in 1972 to Company Developments Limited, when Aston Martin was in financial trouble, for a nominal £100

I call it Tractor SFU; Special Forensic Unit. You literally have to go back in time and find out what each and every owner/operator did to the machine and how to remedy the issues and repairs. These types of enquiries are not unlike scientific enquiries you will do at Uni. I've done this on 30+ machines and it never gets easy, but the knowledge you attain does transfer into real world problem solving. You're going to be very successful.

The Kohler 7hp (k161) and 8hp (k181) both had a bore of 2.938 inches. The only difference between the two engines is the stroke, with the k161 being 2.500 an the k181 being 2.750

Duro Corporation made the first Massey 4 wheel mowers, followed by Beaver MFG which built the first year MF-10 in 1965, In 1966 taking the Beaver MFG design AMP of West Des Moines, Iowa built the MF-10 and in 1967 added the MF12H Hydrostatic model. The MF series continued with 8-16 hp models. The Tecumseh powered tractors were MF-7, MF-8, MF-10, and MF-12 hp models and Kohler powered machines were the MF-14 and MF-16. July of 1976 was the last of the MF series and the newer 1000 series (1200, 1600, 1450, 1650, 1655, and 1855) appeared in the fall of 1976 as the 1977 model year, that series only had a 2 year run until 1979 and there wan't another Massey mower for nearly 10 years after that. The next Massey tractors were built by Case/Ingersoll and were copies of there 200 and 400 series mowers, that run also only lasted two years and then Simplicity was contracted to build Massey mowers in the late 80s early 90's and have ever since. Massey never actually produced any lawn and garden machine themselves.

Glad to see the collection on display
