B250 DIESEL

B-250 serial numbers 16027 to 23467 built 1958,making your tractor autumn-ish 1958 build date.

Starting serial numbers on IH always started at 501.

B-250 built 1956 to 1961. First no. 501; last no. 30260.

5 forward & 1 reverse gears. Live hydraulics via engine driven oil pump, NOT live pto single clutch. Diff lock fitted. Disc brakes. 30HP gross.

64 industrial verions constructed 1958 to 1960.

Early versions had twin steering arms, later models had single steering arm using the better steering box designed for the B-275 tractor.

The B-275 was basically the same tractor with an uprated engine to 35HP gross, and a new gearbox giving 4 F & 1 R, with a hi & lo ratio. Built 1958 to 1968.

The B-414 was uprated B-275 with 40HP gross. Built 1961 to 1966.

All models were popular in U.K., despite being harder to start with heater plugs required for the indirect injection engines. They had high 100 Pounds to 1HP weight ratio, and were better for field work than the equivalent Fordson, MF & DB models of the time. All are very desirable today amongs collectors especially for ploughing competitions.

I have a complete listing for all IH tractors built in Doncaster England, and can help anyone else who requires their tractor dating.

We had many B-250s and B-275s sold in my area of New York. But, since we're fairly close to Canada, I can't say exactly where they all originated, but local IH dealers sold both.
My local Allis Chalmers dealer also sold a British diesel tractor around the same time - the ED-40. "ED" stand for English Diesel", just as the "B" in the IH series stands for "British."

I have a few B-275, B-414s, and an ED-40. The tractor salvage yard nearby to me had a pile of B-250s - he often brings them here from Canada. My early B-275s have air-governors and in-ling CAV injection pumps- and I assume your B-250 has the same?

Mahindra is making and selling tractors under their own name and still using the B-250 platform.

The new E40-DI has a three cylinder 115 cu in diesel. Everything else is almost identical to a
B-275-414 including manual steering and a 8.3 gpm hydraulic pump, except it has a single
clutch. It is rated 39 engine HP @ 2450 rpm and 31 pto hp.

The C4005-DI has the 144 cu in four cylinder diesel that was introduced in the B-250 and B-275 and hydrostatic power steering that was first offered in the 424 and the dual clutch to
give live pto. It also has the 8.3 gpm hydraulic pump. It is rated 39.5 engine HP @ 2300 rpm
and 31.5 pto hp.

The C4505-DI has the 154 cu in diesel that was introduced in the B-414 and also has
hydrostatic power steering and dual clutch. It has 8.3 gpm hydraulic pump. It is rated 43 engine
HP @ 2300 rpm and 34.5 pto hp. All of the gearing on these three models, pto, etc, is of the same design as the 275, 414, 424,
444 line of tractors.

Here are some photos taken yesterday of me beating my little B-275 pretty hard blowing some snow - 7 feet deep in places with a Deere snow-blower. I usually use my 1020 Deere tractor, but it's a 1/4 mile away in a barn and with all the snow - will be stuck there until springtime.
