Ransomes TG4650 cylinder gang

We see it on playing fields, sports fields, parks and other large, open spaces. The TG4650 is a popular choice with local authorities, contractors and even turf growers. So what is its appeal?

Easy: high output, strength of build and the ability to detach quickly, thus freeing up the tractor for other jobs.
It is clear to us, as we watch this mower going through its paces, that Ransomes understands the importance of productivity. This is a seven-unit, trailed, all-hydraulic gang mower with a 4.69m working width. The mower can be fitted with eight- and 11-bladed Sport 200 cylinders, but we test it with a set of Magna 250s (254mm diameter), six-bladed, fixed head cuttings units. Overall it makes a big machine and one that gives an exceptional performance at 10km/h — that’s covering the ground at a rate of 3.5ha/h.
For transport the TG4650 folds neatly to a safe and road-legal 2.28m. The two outer wing units are cleverly and securely positioned on top of the machine to give a low centre of gravity and increased stability when travelling at high speeds. And there’s no problem towing the TG4650 on highways. It is fitted with suspension, over-run brakes and full road lighting as standard.
The remote controls are designed for tractor mounting. They are hand-lever controls operated through pull-push cables and hydraulic control valves. They take a little concentration at first, as Ransomes emphasises safety wherever sharp blades are concerned. There is a lever to lift and lower the centre units. The outer units can be controlled separately to vary the working width, but we are disappointed there is no control to lift and lower all units simultaneously. Selection of forward, neutral and reverse reel drive is via a lever — and you can backlap with this one, if you must. There’s also a big red button to activate reel drive when the units are lowered. Lifting the units brings the cylinders to an instant halt.
Our tester wastes no time mowing the rugby pitch. This mower is tight on the turns and covers the ground at a belting pace. “The mower rides well over the ground and it’s quite manoeuvrable for its size,” observes one tester. The swing drawbar gives good manoeuvrability as it places the mower a good distance from the tractor. Variable weight transfer control is another standard feature.
Height of cut is easy to adjust using a 17mm spanner and keeping an eye on the 13mm gradations.
There’s no doubt the TG4650 is built to last. The chassis is constructed of heavy-duty tubular and plate steel. The drawbar is square-section steel tube with interchangeable towing eyes for tractor pick-up hitch or swing drawbar. Heavy-duty hydraulic pumps are fitted.
Ransomes has also made this mower mechanic-friendly by using a colour indicator on the hydraulic filter and clearly visible gauges for oil level checks. Each hydraulic pump has a diagnostic test port. There are some 56 points that need greasing weekly; but they are all easy to reach.
