Long-ish post, the main points/ subjects are
(
1) General musings about the ground markings, possible dimensions.
(
2)
The UFO landing gear was invented by "UFO investigators", contrary to Robert Taylor's description
(
3) The "ladder" ground markings might have been more superficial than was generally reported
(
4) 10cm diameter fenceposts, and many other things, can leave 10cm holes in the ground
(
5) One account (BUFORA) quotes distances that support Taylor being at the clearing -less clear in other accounts,
(
6) Maybe these RPVs look
a bit like naval mines. Maybe not.

Thinking more about the ground markings from Steuart Campbell's book, usefully provided by
@Giddierone:
If the holes were angled, maybe a small piece of mechanical plant was used to pull out some temporary fenceposts or similar?
Stick down some boards, roll in your trailer-mounted "pulling jib", and proceed, first taking out the posts on the left sequentially in a clockwise direction, move to the right and repeat, pulling them out in an anticlockwise direction
(depending on which direction we think the horseshoes indicate that the holes were angled).
Although the site was only approx. 1 mile, 1.61km from where he lived, I don't know if we know how familiar Robert Taylor was with this specific site. He might have routinely worked farther afield.
Another similar diagram is on the
UFO Casebook site,
https://www.ufocasebook.com/taylor1979.html, below left.
Below right: I removed the circle (not a ground marking, see below) and shrank the holes (they're only about 10cm wide).
External Quote:
Two types of ground markings were found at the scene. The first marks were two parallel ladder-like tracks, each about 2.5 meters long, and the same distance apart. There were also 40 holes around the tracks. They were 10 centimeters across.
UFO Casebook, link as above.
At first I thought this meant each horizontal line was 2.5m, 8'2" long, but this is incorrect; each "ladder" of horizontal lines is 2.5m long.
The circle- which is
not a ground mark- represents the minimum diameter of the main object reported by Taylor, 20 feet, 6.1m.
We don't know how accurate the diagrams are, but using the rightmost set of lines as a "yardstick" of 2.5m, I tried to get some estimated dimensions.
All will be very approximate, with a sizeable margin of error (and depend on the accuracy of the diagrams we've found):
Above right: A wholly subjective impression, but the distribution of holes might be seen as describing two "borders", one around each "track". Each border has 20 holes (if we include the small clump top left with the border on the left).

Incidentally, in the various sources quoted in earlier posts, Robert Taylor always describes the main object as hovering.
He never describes visible landing gear.
External Quote:
Taylor himself was unable to produce a sketch of what he saw. The first attempt was made by David Hammond, then a student architect and the fiancé of his youngest daughter. This sketch showed the 'UFO' standing on four slender legs, but Taylor strenuously denied that he saw any legs...
...A team from the UFO Investigation Network (UFOIN) also visited Taylor and inspected the site of the incident. they saw it as the landing of a spacecraft and concluded that the smaller objects were 'devices'. They were sure that the 'craft' had rested upon the ground and caused impressions in it.
"Report on the investigation of the Bob Taylor encounter", Steuart Campbell, 1994, quoted on the
UFO Evidence website
http://www.ufoevidence.org/Cases/CaseSubarticle.asp?ID=688, my emphases (and added capitals, strangely none in the text).
However, we have a picture -maybe taken some years after the event, Taylor looks older than in 1979 photos- where he holds an artist's impression which shows ladder-shaped landing gear.
But Taylor didn't see any landing gear.
The 'undercarriage' has in effect been invented by UFOIN to (physically) link the hovering UFO with markings on the ground, and Robert Taylor appears to be, at least implicitly, supporting this interpretation invented by people who hadn't seen what he saw, and in contradiction to his own reports/ comments.

Descriptions of the "ladder" markings by visitors to the site differ significantly:
External Quote:
Det Con Ian Wark, the scene of crime investigator, arrived at the clearing to find a large gathering of police officers were already there.
He told the BBC he saw strange marks on the ground. There were about 32 holes, which were about 3.5 inches in diameter, as well as marks similar to those made by the type of caterpillar tracks often fitted on bulldozers.
...The police report from the time said the marks on the ground indicated an "object of several tons had stood there but there was nothing to show that it had been driven or towed away".
(Det Con, more often DC = Detective Constable, the starting rank of UK police investigators)
BBC News, Scotland 19/11/2019

However, the
Journal of Transient Aerial Phenomena, quoted on the
(link) UFO Casebook website, has a very different take:
External Quote:
The ground marks (see Figure 3) were of two types. First, there were two isolated ladder type "tracks" about 2.5 m long and the same distance apart. Each "rung" of the ladder (see Photograph 1), was 2 or 3 cm wide and deep, and about 30 cm long, and the area of grass between each "rung" was evenly flattened, but not as deeply as the "rungs". Although the "tracks" appear to be impressions made by a heavy object, the indentations were only in the grass; they did not alter the ground profile under the grass as they would have done if subjected to a heavy weight.
Did a quick search,
Journal of Transient Aerial Phenomena was published by the British UFO Research Organisation, BUFORA
(
https://en.wikipedia.org/wiki/British_UFO_Research_Association). The quote is from Vol. 1 No. 2, March-April 1980,
"CLOSE ENCOUNTER IN SCOTLAND",
PDF below, pages 41-46 (PDF pages 21-24).
The other issues of JTAP are available here,
https://www.bufora.org.uk/Journal-of-Transient-Aerial-Phenomena.php, 19 issues total, July-August 1979- March '89.
The article includes photos of a "track mark" and a hole (see PDF); annoyingly there is no metre rule, tape measure or other indication of scale, and like other pictures in that issue they are low resolution, high contrast b+w, almost useless- but the text (quoted above)
is useful: The amateur UFO group BUFORA seem less impressed (no pun intended) by the 'ladder' markings than DC Wark was. And BUFORA isn't a
particularly sceptical group, see the Wikipedia entry (link above).
Speculation (rightly frowned upon here)- Dechmont is on the edge of countryside but in Scotland's Central Belt; the outskirts of Edinburgh are approx. 11.4 miles, 18.3 km away; Glasgow 27 miles, 43.5km. Maybe DC Wark was more familiar with urban areas than rural sites back then.
The track marks might be a bit of a nothing-burger. We don't know what caused them, but they probably didn't require any great weight or downward force. There's a photo of Taylor examining the markings- I think he's beside one of the tracks.
It might be telling that, for all the visits to the site, we don't have any
good photos of the markings, and none in colour.
1979; I'd guess most households would have 1 or 2 film cameras (and if not, cameras weren't rare or too expensive).

The site was briefly fenced off (that's probably the fence behind Taylor in the pic above), I'd guess by Taylor's work colleagues, not the police.
Maybe someone had put up a temporary fence or fences there before- 10cm/ 4" diameter fenceposts aren't rare.
Steuart Campbell reported that the local water provider had conducted work about 100m away and that there were pipes cached in a nearby field; UK utilities are notorious for not communicating with each other or with local "stakeholders"; it's entirely possible that the water authority proceeded without liaising with the Livingston Development Corporation (Taylor's employer- not Livingston Council as I put earlier) and left some materials/ plant in a nearby clearing for a few days.
Essentially, if you find 10cm holes in the ground, there are many terrestrial possibilities to consider.

The JTAP/ BUFORA article was useful in another way; I found it difficult to understand Taylor's distance from the UFO from other accounts, e.g.
External Quote:
It took time for him to reach his pick-up truck as he was forced to crawl some 90 yards ( 82 meters) to it.
NICAP,
The Livingston UFO Assault, which implies (to me) that Robert Taylor collapsed that distance from his vehicle.
External Quote:
He later reported seeing a spherical object around 21ft in diameter hovering above the forest floor almost 500 metres away.
Scottish Daily Express 29/07/23
But the JTAP/ BUFORA article's info tells us Taylor had to travel some 520 m, 569 yds back to his truck,
External Quote:
..he crawled on his hands and knees for about 90m back up the track down which he had walked. After that he managed to stand (unsteadily) and half staggered, half crawled the remaining 430 m to where his van was parked
-which ties in with him being close to/ at the clearing where he claimed to see the UFO.

My suspicions are that Robert Taylor had a seizure (
post #13, also #15) without any external triggers, and that this adequately explains his account and symptoms; the ground markings are coincidental and unextraordinary.
But others here might have different ideas.
Perhaps these RPVs might, at a glance, be said to loosely resemble sea mines (thinking particularly about the undercarriage):
Westland Wisp, from 1976. Only 3 built AFAIK, a remotely piloted helicopter that sent back real time TV images.
In two pictures above it might appear dark grey, it's actually black and green camo. (Lower right might be a display model?)
Why any would end up near Dechmont village is a good question, but defence contractors and soldiers do unusual things at times.
Though I think it's extremely unlikely,
maybe one or two of these things sufficiently startled Robert Taylor, or had sunlight reflected off its rotors, and induced a seizure; garbled perceptions led to him associating rotors with the main object -perhaps a large dark tarpaulin or pair of tarpaulins , edges not reaching the ground but tied to surrounding fence-posts, hence the holes. Visible portions of the supporting uprights/ material on the ground under the covers might have been green or camouflaged, blending with the background.
Light filtered through/ reflected off rotors can induce seizures in some people,
