The main thing it needs is new bearings for the shaft that the tines
run in, probably a new drive chain and maybe a new tiller shaft. The
bearings (I guess, there's nothing left of them!) are 'bronze bush'
type ones. Does anyone know of any suppliers that specialise in
Howard Rotavator spares?


The bearings should be needle-roller types, bronze bushes would not
stand up to the workload. The part numbers you require are 253037264
and 252530382 (the needle cage and the outer come as separate items).
The drive shaft and sprocket is part number 64364 and the drive chain is
64393.

We always carry a fair range of Howard parts in stock and all of the
above parts are currently available off-the-shelf. Visit our website at
http://www.davenport.gb.com and enter the part numbers in the "Part
number lookup" field and you will get prices and current stock levels.
You can order online too if you want.

Hope this helps.

Chris.
