Bhagwan Engg. Works, the no-nonsense folks from Malerkotla, Punjab who've been building honest farm gear since 1968 and staying tight with the KS Group, really understand what makes a tractor-straw reaper combo actually work well in real fields. For the best tractor for straw reaper, they point straight to reliable 50-70 HP models that give enough PTO power, good weight for traction in wet or loose soil, and enough hydraulics to handle heavy-duty reapers without bogging down. Farmers in Punjab swear by brands like Mahindra (575 DI or 475), Sonalika (DI 60 or Sikander RX 50), Swaraj (744 FE or 735), John Deere (5050 D), or New Holland (3630 TX) in that range—they pull the reaper smoothly at 2-3 km/h, keep the blower spinning strong for clean straw flow, handle uneven ground without tipping, and don't guzzle fuel like bigger beasts. These tractors pair perfectly with Bhagwan's straw reapers because of solid 3-point linkage, strong drawbar, and easy maintenance—farmers get low grain loss, fast coverage (1.5-2 acres/hour), and less wear on both machine and tractor. In short, pick a proven 50-70 HP workhorse from these brands, and your straw reaper runs like a dream, saving time, fuel, and headaches season after season
