The 4550 4WD’s 38 PTO hp is the first Mahindra figure on this site that clears a 35-hp chipper minimum. Its 48-hp engine also passes several 45-hp ceilings when a maker rates in engine horsepower. On this tractor, check the upper limits as carefully as the minimums.

Scope of this guideU.S. 4WD · 8F/2R full constant mesh gear · dual clutch · open station ROPS. Each configuration below states the model and equipment covered by its sources.
Screen PTO-rated products against 38 and engine-rated products against 48, then remove anything whose maximum is exceeded. For the 8-inch class, compare the 3-hp margin over WC88’s minimum with its much higher full-feed condition before relying on the label.
Mahindra lists 48 engine hp and 38 PTO hp for the 4550 4WD in both the current table and the linked brochure, with no named engine standard.
WC88’s 35-PTO-hp minimum is cleared by 3.0 hp; Woodland Mills ties full 8-inch logs at full feed to over 60 PTO hp.
48 engine hp exceeds Farmry WCAP5’s 45-engine-hp maximum by 3.0; WC46, TFG55 and FM-54 Y are exceeded on PTO power.
The Farmry LFS series (15–35 hp, basis unspecified) is exceeded on both engine and PTO figures. LFP47’s 25–45 band is exceeded on engine hp only.
FM2572’s 42-hp minimum is cleared on engine power but not PTO power; Wallenstein BX72S’s 50-engine-hp minimum is missed by 2.0.
A rear remote spool is listed as standard; lift is 3,527 lb at 24 inches in the web table. The web table’s 103.74-inch height conflicts with its own 2,380-mm figure.

U.S. 4WD · 8F/2R full constant mesh gear · dual clutch · open station ROPS
38 PTO hp
Mahindra 4550 4WD open-station ROPS gear tractor (8F/2R full constant mesh, dual clutch) in the current U.S. 4500 Series table and linked brochure. No model-year or serial cutoff is established.
Engine power
48 hp · 48 hp at 2,300 rpm labeled “(T4)” in the current 4500 Series specification table and the linked brochure. The rating standard is not named. This is not PTO power.
Rear hitch
Category 1 and 2 adjustable with telescopic stabilizers, position and draft control (Mahindra 4500 Series table and brochure)
Lift at 24 inches
3,527 lb · 3,527 lb at 24 inches aft in the current 4500 Series web table. The linked brochure lists 3,527 lb for 4WD models without naming the measurement point. No lift-point figure is published.
Lift at link ends
Not confirmed in reviewed sources
Hydraulics
8.7 gpm implement pump (open center, full-live with position and draft controls) in both sources; steering pump is listed separately in the brochure. Rear auxiliary remote: 1 spool standard (brochure). No usable outlet flow is published.
Pressure
No tractor relief pressure is published in the reviewed table or brochure. The brochure’s 2,350-psi figure is the 4550B backhoe’s relief valve setting, not a tractor rear-remote rating.
The current web table labels 3,527 lb as lift capacity at 24 inches aft. The linked 4500 brochure lists “Lift Capacity (lbs.)” of 3,525 (4540 2WD column) and 3,527 without stating the measurement location.
The web table’s located 24-inch label is used for 3,527 lb. Confirm the figure and measurement point in the operator manual for the actual serial.
Overall height
The current web table lists the 4550 4WD at 103.74 in. (2,380 mm); the brochure lists 93.7 in. (2,380 mm).
2,380 mm is 93.7 inches; the web table’s inch figure appears to be a transcription error. Height does not enter the attachment screen; measure the actual tractor for storage or doorway clearance.
