Yes — from the photos, that appears to be an older Howard Rotavator (or possibly a Lely or Ford-branded version of the same machine). Here are the key identifiers that point toward a Howard Rotavator:

Distinctive gearbox shape and side cover – the large rounded gearbox housing with the bolt-on access plate is a hallmark of Howard tillers from the 1960s–1980s.

Heavy-duty chain drive housing – Howard used an oil-bath chain case on one side (as seen in your photo) rather than a gear drive, which matches that large bulged cover and filler plug.

Adjustable tailboard and depth skids – the rear panel with side plates and chain support are classic Howard design elements.

Three-point hitch configuration and PTO shaft setup – the overall geometry matches Howard’s “HR,” “Rotavator E,” or “Rotavator 60/70” models.
Likely model
It looks most like a Howard Rotavator HR30 or HR40, depending on the width (around 60–80 inches wide).
If you measure the working width and find a tag or stamped number on the gearbox housing, it can confirm the exact model.
Common models from this era include:
HR30 – ~60" tilling width
HR40 – ~80" tilling width
Rotavator 70 series – similar build but newer decal style
Notes
These units are PTO-driven (540 rpm), chain-drive tillers, very durable, and still serviceable.
Gearbox oil and chain case oil should be checked or replaced before use.
Howard was originally a British company (later acquired by Daken/Howard Australia and CNH).
If you can find a data plate (often on top of the gearbox or left-hand side near the hitch frame) or give me the overall width, I can narrow down the model exactly.
